1 1.1 Project contents and scale 1.1.1 General Situation to Project For recent years, Tongxu County develops quickly in industry production. With the increasingly expansion of city scale, the growth of population of county seat as well as the continuously improvement of the people's living level, the water supply in Tongxu County is severely insufficient, which considerably constrains its economic and social development. Therefore, to build urban water supply network works and to set up a complete, rational and sound water supply system has become urgent. The Tongxu County this time, by the help of loan offered by World Bank, will build a water supply system with daily water supply capacity of 35000 m3/d. 3 Presently in Tongxu County, there is 1 water plant with water supply capacity of 8000 m /d, the water-consumption population is around 50000, and the consumption rate gets to 52%. The water supply is short, the contradiction between supply and demand is obvious for which sometimes suspension of water supply happens and severely affects the normal living of the people. In addition, the water supply network in this county is unreasonable with its overall arrangement, the technology of water treatment plant is incomplete, and the factors like the insufficiency of water-treatment degree have limited the development of water supply industry. In light of 2002-2010 City Overall Plan of Tongxu County, it is predicted that the gross 3 3 water consumption of county seat in 2010 be 43400 m /d, while that in 2020 be 75900 m /d. So the construction for the water supply project will effectively relieve the tension situation of short supply. As a World Bank-funded project, this project is under the general organization by Henan Project Office. The preparation period of this project is from Jan. 2005 to Jun.2005, the construction period is from Jul.2005 to Aug.2006. It is predicted that this project will be put into use by the end of 2006. The total investment for this project is 5346.07 ten thousand yuan.

2.1.8 Major environmental problems in project area
Tongxu County is one of the city-level counties directly under jurisdiction along Huaihe River and also one of the main pollution sources of Huai River. For many years, the domestic water and processing water of Tongxu County Seat are mainly drained into the west branch of Old Channel without any treatment, those of some areas are penetrated directly into underground which causes pollution to the groundwater of shallow layer. The water quality for west branch of Old Channel is polluted severely due to having received the domestic sewage and industrial wastewater, and the contents for pollutions factors like the PH, COD, BOD, non - hydronium ammonia all have exceed the Category V standard value as stated in Standa'dfor Quality of Surface Water Environment. The pollution of water body has directly caused the pollutions to shallow-layer groundwater and the farmland on banks along the river and endangered the body health of the people on banks. 2.1.9 Basic intensity
The basic intensity of Tongxu County is Degree V.
7 2.2 Social Environment 2.2.1 Administrative allocation and population

And the built-up area is 1Okm ; while the population in 2020 will reach 160000 people, built-up area will be 15 kM2, at the appointed time, the county seat will show its strong attracting strength and radiation strength in social & economic development, as a political, economic and cultural center, Tongxu County will present its city characters obviously and become a modem city of Yudong Plain. 2.2.2 Gross domestic products
The economy of Tongxu County gives priority to agriculture. There is cultivated land of 1151000 mu, per capita cultivated land 1.95 mu, the per capita cultivated land for agricultural population is 2.14 mu. The principal crops involve wheat, com and soybean etc., commercial crops involve cotton, peanut and rape etc., in addition to multi-amphisarca, vegetable, tree and pent. In 2002, the grain gross production gets to 268692 Tons, while the output of oil plants to 30151 Tons, the cotton gross production to 10838 Tons and gross production for amphisarca and vegetable to 1178490 tons. In the last few years, the planting area for economic fruit-bearing forest has increased substantially, covering apple, peach, grape etc., the fruit-bearing forest area in 2002 reaches 19100 mu. The total output value of agriculture in 2002 reaches 144062ten 144062 ten thousand yuan. In Tongxu County, the industrial base is poor, and the industrial development is very slow in the period from the foundation of China to the 1970s. However, with the help of spring breeze of reform and opening up, economy of Tongxu County sees a mushroom Growth, the industrial undertaking also develops vigorously, and the core industries like the processing of subsidiary agricultural products, chemical industry, construction, textile and leather etc. have driven the development and growth of other industries. By the end of 2002, the industrial enterprises at township level or above have counted up to 3595, the gross output value of industry in 2002 has gotten to 304705 ten- thousand yuan. As a historically famous market town,' the Tongxu County seat is developed with commerce and trade. Of late years, as the increase of surplus labor and the inrushing rural population into county seat, more and more people are engaged in the third industry, presently there are 3226 business stalls throughout county seat, and, by the end of 2002, the gross amount for commerce and trade service has gotten to 93559 ten thousand yuan. 2.2.3 Development goal and overall plan of county seat
In light of the Overall Plan of Tongxu County Seat (2003-2020), the overall goal is concemed with that the county seat will, on the basis of using the industry to prosper this county and enhance economic strength gradually, be built into a political, economic, cultural and Scientific information center, as well as a modem city giving priority to food and textile industries, supported by commerce and trade industries. The population and scale of Tongxu county seat are planned as: by the end of 2003, the population is 11000 people, the city zone area is 10.9 kin2 , the resident population is 98000 people, and the gross industrial output value is 1 billion yuan. In light of the development program of county seat, the population in 2010 in built-up area of county seat will be 130000 people, the land used for construction will be 20.6 km2 ; the population in 2020 in built-up area of county seat will be 160000
8 people, the land used for program will be 80-100 km2. (1) Principal industries and development program of county seat The economy of Tongxu County which is developing rapidly in recent years has formed a industry system supported by such industries as processing of subsidiary agricultural products, chemical industry, construction, textile, machinery manufacture, illumination industry etc. In light of Overall Development Program of Tongxu County Seat (2003-2020), the overall development goal is concerned with that the county seat will, on the basis of using industry to prosper this county and enhance economic strength gradually, be built into a political, economic, cultural and scientific information center, as well as a modern city giving priority to food and textile industries, supported by commerce and trade industries.
(2) Development goal for industrial economy 1) The industrial enterprises over the county should complete their adjustment of product structure in such a way that the industrial structure and economic structure is going in reason. The production equipments, technical level, management level, product quality could get to a new stage. The innovation dedication ratio as of 2006 may reach over 50%.
2) One or two big brand products which may affect the development of national economy should be cultured so as to produce a fist product to enter into national market and international market and thus drive the development of overall county economy.
(3) Construction program of major industries Major industries play a vital role in industrial economy and considerably affect the development tread and scale of industrial economy. In light of the industrial policy and the status quo of industries of Tongxu County, the.major industries involve: textile industry, machinery industry, light industry and food industry etc. 2.2.4 Status quo of water supply and water source protection
At present, the water supply is.undertaken by County Water Undertaking, which is founded in 1982, 3 with supply capacity of 8000 m /d, for which the water source is from groundwater, and there is 7 water-supply wells, 2 water tanks. The water supply area is 7.5 km2, and the application ratio of water supply gets to 52%. The DN75-300mm pipeline laid with Xingzheng Road, Renmin Road, Wenwei Road, Jiefang Road, Old street and north to Yinbing Road etc. is 15000 m long. Presently, the problems existing with the water supply of county seat mainly cover the following: ID Water supply is short, the contradiction between supply and demand is obvious; (2) The protection measures to water source is not powerful, the blind exploitation is serious; () The technological equipment for water plant is incomplete, the water treatment depth is not enough; (I The pipeline is unmatched, its allocation is not reasonable; © The sources of groundwater fail to subject to general management. The protection measures for water sources involve: (X) to enlarge the area of water saving and irrigation, to reduce the produced quantity of groundwater I) to subject the surface water and groundwater to the overall program, adjustment of storage jointly; I) to improve the recycle ratio of industry-purposed water, to drain the wastewater only after meeting the standard. 2.2.5 Discharge and wastewater treatment program of city
9 (1) Discharge of wastewater Hypsography of Tongxu County is high in west and low in east, the overall gradient degree is small, the mean gradient ratio is around 1/5000. The main draining riverway for county seat refers to the east branch of Duzhuanghe River. The existing draining direction for storm sewage runs in: storm sewage for county seat- west branch of Old Channel- Old Channel of Wohe River- Wohe River- Huaihe River.
(2) Existing environmental problem At present, the domestic sewage for county seat and partial industrial wastewater both are discharged directly, which causes pollution to surface water system and groundwater sources. The existing problems concerning discharge system for county seat involve: the draining pipeline system is unsound, the existing draining pipelines mostly fail to satisfy the design standards for setting depth of gradient of rain pipe and channel, draining in partial county seats is non-smooth, in addition, the confluence for storm sewage, the water quality of surface water is poor and the environmental pollution is heavy. The existing problems concerning the water supply for county seat cover the following: (G) insufficient of water supply capacity; (0) unmatched equipments with water plant; (a) the water quality failing to meet the standards; (G) the pipeline is unmatched, the application ration of water supply is low; (5) the groundwater lacking of overall management etc.

The water supply potential of tap water for Tongxu County for this time is far from meeting the demand which gives rise to a great inconvenience to the people's living and economic development. Presently, due to short supply with water, the inhabitants and partial enterprises use water by the aid of self-provided wells for which the water quantity and quality are both instable, which directly influence the health of the people; in addition, the groundwater is in disorder exploitation, which is adverse to the sound distribution and protection of groundwater. In light of the investigation of Tongxu Sanitation and Antiepidemic Station to the endemic fluorosis situation, the dental fluorosis and Kaschin-Beck disease are the commonly diseases encountered by the inhabitants of county seat and its surrounding, with cardinal symptoms like the dental fluorosis and pain with articulation. The existing investigation data for the 12 villages and towns and 611 natural villages of Tongxu County see to the following schedule:
1 2 Table 2-3 Schedule of endemic fluorosis station investigation

Slight-degree village Mediate-degree village Heavv villagee
1985 90 278 59 5146 72.8
2003 457 / /
As viewed from above schedule, the long-term drinking the shallow water of high-content fluorine may cause to some extent the fluorosis cases, and, the disorder exploitation of groundwater is non-beneficial to the rational disposition and protection of groundwater.

Major ecological impact: The major ecological impact for this water supply project mainly involve the construction of water source area project in which the farmland vegetation will be damaged, and the construction of conduit pipe in which it is not necessary to pass through riverway and bridges, the construction type is subject to a by-stage construction during which the filling work can be done at the same time, therefore it brings a slight impact to ecological environment due to short construction period, and, few soil and water loss. In addition, the construction of water distribution plant may considerably damage the agricultural vegetation, however, the hardening and afforestation to water source area and plant site may, after the completion of project, be adopted in such a way to reduce its impact to an undermost degree.
2 0 7. Environmental Impact Analysis
7.1 Environmental impact and pollution control measures at construction stage 7.1.1 Analysis to water environmental impact
The sewage at construction stage is mainly originated from domestic sewage of construction staff, which may cause no impact to surrounding water body due to small quantity and few pollutants. 7.1.2 Analysis to impact due to dust pollution
The dust pollution at construction stage involve two types, one type refers to the dust produced during transporting building materials, such dust may, due to transportation line being so long, cause pollution in transportation line if no proper pollution control measures are adopted. However, the evaluated project is located north to Old county seat, it will, after adopting some proper control measures during transportation, cause slight impact to the people. Another type is concemed with the dust which is produced at constructions, such as the in-field earth excavation, on-the-spot piling up, on-the-spot field conveying and piling up of building materials, clearance and piling up of construction refuses etc. The dust at construction field may give rise to some impacts to the work staff and those areas at wind direction. The construction unit must do well the water spraying work at those areas the dust is likely produced like the piling-up field, construction site, so as to keep ground humidity; the materials which may likely produce such dusts as cement and lime shall be stored in material storage or covered with canopy cloth. 7.1.3 Analysis to impact due to noise pollution
The main noise sources at construction stage come from such high noise equipments as excavator, pile driver, jolter, cutting machine, electric saw etc. the maximum source intensity value is I 1OdB (A) . The noise which the project produces may give rise to a big impact to surrounding environment. Clause 30 as stated in the Prevention and Treatment Law on Noise Pollution of the People's Republic of China defines that the constructions at night which may produce environmental noise pollution is forbidden. Therefore, the construction unit shall avoid an at-night construction as far as possible, and the high-noise equipment shall work to avoid nooning time; the pipeline's construction shall, when passing a sensitive area, be done in manner of labour excavation so as to control the noise impact to the undermost degree. 7.1.4 Analysis to impact due to solid waste
The solid waste at construction stage involves the building refuse and construction earthwork, among therm, the building refuse refers to those produced due to dismantling the former building at the previous stage of construction, the construction refuse refers to the building refuse and waste earthwork. The solid waste at construction stage reaches to an amount of around 14000 tons. If failure to treat solid waste in time, it will produce a secondary dust and thus cause partial environmental pollution, which may bring impacts to site staff and surrounding environment at leeward direction. The construction unit shall clean the building refuse out of construction site timely and send them to local special waste treatment site or piling-up site, and shall backfill the waste earthwork into natural
2 1 low bottomland timely. 7.1.5 Analysis to ecological environment impact
The impact of the purposed project to ecological environment is mainly concerned with the cultivated lands to be occupied by the construction of water distribution plant, and the farmlands and road to be occupied during the laying of conduit pipeline. The environmental impact caused by laying of conduit pipeline is mainly concerned with the construction stage, including the following: (1) Damage to agricultural ecological environment on the way (O Temporarily occupied farmlands will reduce their grain output, which will also cause a temporarily damage to the agricultural ecological enviromnent which have come into being in local place. (O) The large amount of earthwork which is excavated during construction will change directly or indirectly the partial ecological environment and further reduce the fertility of soil. 0)The cut-away trees during construction will also give rise to a relative impact to surrounding ecological environment, but the amount is small and may be recovered reasonably after the cornpletion of construction, for this reason, it will not cause a long-term adverse impact. 7.1.6 Impact to city ecological landscape due to construction
The piling-up of materials at construction site, the set and use of construction instruments, especially the excavation of road and the piling of earthwork at the construction of pipeline, all will cause an adverse impact to the overall harmonious ecological landscape. 7.1.7 Impact to sensitive spots like the natural reserve scenic spot, cultural relic and historic site due to construction
There are no sensitive spots like the natural reserve scenic spot, cul--iral relic and historic site appeared in the water source land, water distribution plant and along the laying line of pipe network. 7.1.8 Impact to residents' living due to construction
The impact at construction stage will be slight to the people surrounding due to no sensitive spots being found within 2000m away from the water source land and water distribution plant. 7.1.9 Rational analysis to environment on resettlement plan
No resettlement problem is concerned with this project. The impact of this project to local residents involve two aspects, one is the impact to local residents due to land acquisition required by water source land, another is the temporarily impact to local residents due to construction.
(1) Permanent occupied lands of this project The lands acquisition in this project is 36 mu, among it, water plant occupies lands of 18.9mu, water source land occupies lands of 17.1 mu, all of the lands belong to cultivated lands and are possessed by collectivity. The impact to area of occupied lands before and after construction of this project is presented in the table 7-1. (2) Temporarily used land at construction stage It refers to temporarily supplied lands at construction stage, including the sandstone stock ground for boring well, temporary road at construction stage, lands occupied by the construction of pipeline, the temporarily occupied land is around 70 mu.

lands Per capita cultivated lands Mu/people 1.1
after the Total population People 198
occupation of Total cultivated lands Mu 181.8 Reduced by 16.5%

(3) Population affected by the project The Population affected by the project refers to those people affected by land acquisition. In reference to site statistics, the land acquisition by water plant has actually affected 6 families, 24 people in total, and all of them belong to the agricultural population. In sum, the people involved in this project, no matter the permanent occupied land or temporary occupied land, is few and does not require resettlement, except for a rational compensation as per concerned national policies. 7.1.10 Environmental rational analysis to choice of earth-material stock ground, excavation waste dump
The building materials used at construction stage shall be conveyed by demands, which will not cause to much piling, so they will be piled up at construction site and covered by a poncho so as to prevent from dusts due to wind or, losses due to rain. The waste earthwork and building refuse will be temporarily piled up at construction site, among them, the earthwork will be backfilled timely, the rest earthwork will be used to fill in pits, while the building refuse will be cleaned away and transported to a city building refuse store ground. 7.1.11 Impact to the city traffic due to construction
The transportation of building materials and building refuse at construction stage will augment the traffic loan, but such adverse impact is slight for the reason that the plant address is far away from urban area and there are few vehicles going along transportation line. The laying of urban water supply pipe network may do a big adverse impact to city traffic and may cause a blocking at construction stage, for this reason, a temporary convenient pavement shall be set on the busy road, and also the construction shall be done by stages and shall be completed as soon as possible. In addition, the construction shall avoid the busy time with regard to a very busy road. The excavated earthwork shall, in addition to used to backfill, be removed timely, the piled-up earth shall avoid to occupy the road as far as possible in order to ensure a smooth traffic for the excavated road. 7.1.12 Impact to the people's health due to construction
The noise and dust produced at construction site may cause some adverse impact to the body health of construction staff, what's more, the dust in a big-wind day may cause a adverse impact to the health of
2 3 those people at leeward direction. 7.1.13 Impact to local society and economy due to construction
A large number of construction raw material needed in construction may bring some business chances to building material market. In aforesaid various impacts, the majority of impact of the project proposed to surrounding ecological environment will be temporary, except that the lands occupied by the construction of plant site may do a permanent impact; all of them will end by the completion of construction and will not give rise to a significant damage to surrounding ecological environment. 7.2 Environmental impact at operation stage 7.2.1 Impact to groundwater source of water source lands due to water consumption by project 2 The water source land for this project is proposed at a 3km area which is north to county seat, west to Wohe River, east to Gongkai Road. According to the preliminary survey conducted by the geophysical reconnaissance center of China Earthqiuake Bureau, the water bearing layer of the soil of this area features thick granule, large water yield, good water quality, so the quantity of water is sufficient and certified; in reference to the reconnaissance report, the allowable production for the water source area is 50400 m3 / d, the actual produced quantity is 35000 m3 / d, accordingly, it could meet the exploitation demand of 35000 m3 / d by this project. Presently, the groundwater the produced quantity for deep groundwater is few, the deep groundwater is mainly drained in manner of underground runoff and drained toward lower reach, in this sense, it is a advantage for using deep groundwater. Therefore, the water intake project with capacity of 35000 m3/d will not produce a big impact to the groundwater sources of this region. 7.2.2 Impact to ecological environment due to water source area and permanent occupied land
The permanently occupied land covers an area of 36 mu, among it, the water plant occupies lands of 18.9 mu, water source land occupies lands of 17.1 mu, all of them are cultivated lands and possessed by the agricultural community. The permanently occupied land will cause an impact that the former structure of earth surface is affected, the vegetation is damaged as well as the status quo of land use and the origin ecological system are changed partially. Therefore, the ground for plant site shall be hardened during construction, the vegetation surrounding plant site shall be recovered so as to avoid the occurrence of soil and water losses. The water demanded by ground plants is mainly from the shallow groundwater, the water source used by project belongs to the semideep groundwater and deep groundwater. As has a preferable isolation layer to the shallow layer, the water power connection is not close, and, the intake of water by project will not cause a vertical supplement to shallow groundwater and so will not affect the growth of ground plants and not cause a ecological damage. 7.2.3 Impact to production water and domestic water of local farmer due to intake of water
This proiect will not cause imact to the production and domestic water of the local people for the
2 4 reason that there is no villager and no irrigation well in the water source land. The farmland irrigation gives priority to the irrigation by Yellow River water which is introduced through the Qiliwan of Huigu Ditch and distributed into each branch ditch through the west branch of Wohe River. A planned exploitation of groundwater source will be in favor of the use and distribution of water source. After this project is completed and put into use, the exploitation area will be supplied with water by flow pipe network.
7.2.4 Analysis to potential pollution source of water source area
The old channel of Wohe River is located at the east to water source land, Hugu Ditch at west, west branch of old channel at southwest. The Wohe River is also located at the east to the county seat, the water quality is good when it flows by the upper reach of water source land. The Huigu Ditch refers to an irrigation ditch by Yellow River water, the water in it is from Yellow River. The west branch of old channel is originated from the Dashuanggou Village lying at the north center of this county, flowing into the old channel of Wohe River at southwest direction at Maoli Village, the water quality at upper reach is good and falls down gradually due to receiving the domestic sewage and industrial wastewater, classified as category V. The rivers above have a function of alimentation to shallow groundwater. The mining water source for this project is the groundwater of semideep layer, which has no direct hydraulic connection to surface water, and no pollution sources surround the water source land. Additionally, during exploitation, a water-stop measure is applied to positions above deep layer in the water-source well, so the upper-layer groundwater will not vertical leakage to the semideep water layer, except that a safeguard will be carried out to the water source area after the completion of project. For this reason, it has a slight impact to the water quality of outlet water. 7.2.5 Discharge of Pollutant at operation stage
(1) Impact on water environment The project's impact to surface water is mainly due to the domestic sewage produced in office and living at operation stage. The discharge volume is 1440t/a, and the key pollutants involve COD of 3 146mg/m , ammonia nitrogen of 23mg/m 3, 0.033t/a, as well as PH: 6-9. The produced pollutant is few due to a small discharge volume, and will be drained into the city sewage pipe network after treated by septic tank, then drained into the old channel of Wohe River through west branch of old channel, so it has a slight impact to surface water environment. (2) Impact on atmosphere environment The project purposed does an adverse impact to surrounding atmosphere environment only when occurrence of leakage of chlorine. The little leakage of chlorine during normal production produces a very slight impact to regional atmosphere environment. (3) Impact on acoustic environment The noise for project proposed is produced when the water pump runs during water intaking and water transfer, the source intensity value is around 80 - 85 dB (A). The low noise equipments to be applied in this project will achieve in that the annoyance value 1m away from the pump room may be reduced to 60 -65 dB (A) by adopting such means as application of basically shock Absorption, semi-underground machinery room, deafening etc. In this way, the noise at plant boundary is predicted to meet the standards.
2 5 7.2.6 Risk accident analysis
At present, the domestic tap water production generally use the chlorination means. So the chlorine cylinder shall be strictly controlled in use and preservation to prevent from the occurrence of leakage accident. The probability of occurrence of leakage of liquid chlorine still exist although the probability of occurrence of leakage of liquid chlorine is very little; when in trouble, it may cause hurt to human body and animal, the chlorine may excite the eye, nose, throat, and will has a strong impact on the human's health and even cause to death once a ten-thousandths chlorine contents is maintained in air. In design, a automatic monitoring and waming device for chlorine is mounted in chlorinator room and chlorine storage, in addition to the mounting of safety materials and formulation of emergency measures, for this reason, the contamination accident may be reduced to an undermost degree. 7.2.7 Risk analysis to environment
The water intaking layer for water source area refers to the semideep layer (100 - 150m) and the deep groundwater (500 - 650m) . There is no fear of occurrence of a suddenly contamination accident for the reason that the surface water's impact to it is very slow and there is no other industrial pollution sources surrounding the water source area. 7.2.8 Environmental problems due to the augment of discharge volume of city sewage in future
With the enlargement of urban scale and the rapid development of economy, the city water demand will be augmented, so do the discharge volume of sewage. In light of the requirements of WTO of Provincial Financial Department, the newly-built water supply works shall give priority to satisfying the near-future construction demand, namely satisfying the urban water supply demand in 2010. By the requirements above, it is predicted that the water demand as of 2010 will be 43400 m3 /d, and the discharge volume of sewage will, if the discharge coefficient of sewage is calculated by 0.8, be 36000 m3/d; presently, the wastewater treatment project of 25000 m3/d (Stage I) of Tongxu County is in preparation, various approval procedures of which are on going, and which is predicted to be launched in December 2005, and put into use in December 2006; after its completion and putting into use, the discharge volume of produced pollutant will be reduced greatly, for this reason, the quality of surface water environment will be thus improved obviously. After the wastewater treatment project of 25000 m3/d is built and put into use, the wastewater will, by the west branch of Old Channel, be drained into the Old Channel of Wohe River; the key pollutants contained in the left water involve the COD of 39.2mg / 1, / ammonia nitrogen of 6.2mg / 1; and the discharge amount for COD and ammonia nitrogen has been reduced by 2281 t / a and 137t / A respectively; the discharge amount for COD and ammonia nitrogen after treatment is 730t / a and 137t / A respectively; and the put-down ratio gets to 75.8% and 50% respectively. In this sense, the construction of this wastewater treatment project may lead a big improvement of quality of left water of Old Channel of Wohe River and consequently considerably dedicate to the water pollution control of Huaihe River watershed. After the project is completed and put into use, the discharge volume for COD and ammonia nitrogen may satisfy the gross control index as stated by Kaifeng City. For details of the geology location for wastewater treatment plant, please see to Attached Diagram I. 7.2.9 Protection measures to environment at construction stage
2 6 T'he key pollutants at construction stage, no matter the construction of water distribution plant or that of water supply network, refer to the dust and noise. Therefore, the following measures are purposed: (1) The dust is prevented by means of sprinkling water, enveloping, backfill of earthwork timely, removing the construction waste and surplus earth timely etc., so as to reduce the pollution to an undermost degree; (2) At construction stage, it is forbidden to apply the measure closing down construction site to reduce noise because the construction of water distribution plant as well as the laying of pipe network must be done in the open air. We had better apply such measures as prohibiting the construction at nighttime, setting.up temporary sound barrier devices so as to reduce the noise to an undermost degree. (3) We shall inspire a civilized construction with a view to "In-favor-of-people project", and coordinate and solve timely the existing environmental problems at construction stage by the organization of the construction unit, liaison party of street committee and Proprietor. 7.2.10 Environmental protection measures at operation state

(1) Saving water resource Presently, there are many self-service wells in county seat, with water quantity of 27000 tld. The free mining groundwater for a directly use, due to its bad water quality, not only causes a great waste of water source, but also do harm to local people's health. After the completion of this project, those self-service wells which are covered in the scope of tap water pipe network (within the plan area of county seat) is proposed to be stopped, and the groundwater in this area will.be mined by plan and thus the water source is saved.
3 2 (2) To be in favor of the urban fire fighting Up to now, the water pressure of some fire hydrants is deficient due to the occurrence of aging with old pipe network and heave phenomena like running, emission, dropping and leaking, which has done great harm to the fire fighting. The water supply capacity after the completion of this project will be greatly improved and thus provide a strong guarantee for fire fighting.
(3) To be in favor of urban ecological environment As one of the counties directly under city-level administration along Huaihe River, Tongxu county is one of the major drain sources of Haihe River. For many years, the most of domestic sewage and production wastewater of county seat is drained without any treatment or by simply treatment into the west branch of old channel, which affects the urban environmental quality and area landscape. Over many years, the west branch of old channel has received most of industrial wastewater and domestic sewage and thus becomes a principal drain channel of this region. With the rapid development of economy, the water quality of rivers is polluted heavily, the pollution factions like the PH, COD, BOD, non - hydronium ammonia etc., all have exceeded the maximum value of category V of Standard for Quality of Surface Water Environment, which gives rise to a heavy pollution to groundwater and earth, in addition, the large number of drained sewage over standard also bring a great difficulties to the harnessing of Huaihe River. As per the requirements of "Tens Five" Plan of Tongxu County, the construction of city WTP will do favorable actions in such aspects as collectively treatment of urban domestic sewage and industrial wastewater to achieve in the gross control of region pollutants, improvement of local environmental quality as well as protection ecology.
3 3 10. Conclusion and Proposals
10.1 Conclusion (1) This project which making use of work bank loan is approved by development plan Commnittee of Henan Province and undertaken with construction by Tongxu Water Undertaking, it is composed of three parts, namely water intaking and water transfer project, water distribution plant project, water distribution network project. The total investment is 5346.07ten 5346.07 ten - thousand yuan, the planned water supply potential is 35000 t/d. It is to be put into use in December 2006. Its construction will abate the contradiction between supply and demand of water supply, and impel the development of regional economy. (2 )The use land in plan for this project covers an area of 36 mu. The water distribution plant is located at the northwest to county seat, at the cross between Beihuan Road and Jiefang Road which is planned as the administration and living habitat, and there is no pollution nearby. The water source land for this project is purposed at the area of 3km2 which is north to county seat, west to Wohe River, and west to Tongkai Road, all of them is cultivated land. The location of project conforms to the City Overall Plan of Tongxu County Seat (2003-2020), the site selection for contraction is feasible. (3) Belonging to the production and supply industry of tap water, this project, no matter its type or scale, is not listed into the List for National Projects Being Washed out and Limited and basically complies with national industrial policy, after completion, it may achieve in annual income of 1463.67ten thousand yuan, in this point, the enterprise economic profit is good. (4) The water source land for this projecn, tl,e distribution plant will be evaluated as per Program I. The water source land is located at an area of 3km2 which is north to county seat, west to Wohe River and east to Tongkai Road. The groundwater quality of this area, in reference to the survey by provincial geology company, is good; the water capacity is proved and could meet the supply demand of 35000 m3/d, so it will not affect the groundwater reserve in a short term. While the water distribution plant is located at the north to county seat, at the cross between the Beihuan Road and Jiefang Road, where it is planed as the administration and living habitat, so it is in accordance with the Overall Plan. Therefore, the site selection for water source land and water distribution plant is feasible (5) The productions and drains of pollutants at construction stage. The domestic sewage and refuse volume at construction stage is very little. The key pollutants involve the construction noise, building refuse and dust. The noise at construction stage shall be carried out strictly as per the Noise Limitation at Boundary of Building Operation Field, so it does a slight impact to its surrounding. The building earthwork shall be backfilled timely, the building refuse shall be removed to building refuse ground timely. During construction, especially when encountered a big wind, water shall be sprayed as much as possible to prevent to dust pollution. The material transportation shall be ensured with a cover to prevent form wind and rain and secondary dust pollution. After application of the integrated control measure, the temporary pollution at construction stage may be reduced to an undermost degree. (6) The productions and drains of pollutants at operation stage. Wastewater: the sewage source at operation stage refers to the domestic sewage produced by staffS, the key pollutants involve COD, ammonia nitrogen. The sewage will, after treated at septic tank, be drained into city sewage pipe network, then into west branch of old channel. The discharge volume of wastewater gets to 1440 tons, the discharge volume of COD to 0.21 tons, the ammonia nitrogen to 0.033 tons, so which will cause a
3 4 slight impact to regional water environment. Waste gas: There is no industrial waste gas to be discharged at operation stage. However, when occurrence of leakage of liquid chlorine, it will cause pollution. This project will apply a strict emergency countermeasure for accident to avoid the occurrence of accident as far as possible. Solid waste: The solid waste in this project mainly comes from the sludge produced in sedimentation tank and the domestic refuse of office; the domestic refuse may get to an amount of 15 tons, which will be treated soundly, treatment ratio of 100%, so it will not cause an impact of piling storage to surrounding environment. Noise: The operation noise which is produced by pump in water intaking pump room and water transfer pump room will be treated integratedly, so the noise source intensity value will be controlled effectively and the noise at boundary meets the standard. The domestic sewage, solid waste, noise will not, after application of above pollution control measures, produce an adverse impact to environment. The waste gas will not, upon strictly control measures, produce an adverse impact to surrounding atmosphere. (7) Multi-plots of green lands ares reserved in plant area, with afforestation Area of 5000 m2, afforestation ratio of around 40%. (8) The investment concerning environmental protection for this project is around 65 ten thousand yuan, accounting for 1.2% of total investment. 10.2 Proposals
( 1 ) Ensure the fulfillment of above various environmental protection measures. (2) Enhance the protection of water source land; those projects which are not concerned with the protection of water source are forbidden; it is forbidden to drain sewage into or pile up solid waste at the upper reach of water source as well as its surrounding, so as to avoid the pollutants to pollute the water source via infiltration. (3) The well group allocation, the well space within mining area shall be subject to the overall consideration and rational treatment of design unit. (4) At construction, the anti-leakage work of conduit pipeline shall be done well to prevent from the pollutant infiltrating into pipeline and further affecting the water quality. (5) During construction, we shall improve management; it is forbidden to produce noise at nighttime to affect surrounding environment, the operation at daytime of high-noise equipment shall avoid the lunch break. (6) After the project is put into use, the afforestation and beauty work in plant site shall be done well. It shall be ensured the septic tank and the sewer line shall be cleaned and repaired well; the domestic refuse shall be cleaned and removed timely to avoid any piling up or storage. (7) The management of the chlorinator and the leaking chlorine absorbing device shall be enhanced. Especially for leaking chlorine absorbing device, it shall be checked regularly to ensure such equipment is in normal running. It is suggested that sodium hydroxide shall be applied to absorb the chlorine due to its lower price, in addition, it could achieve in a secondary application because the hypochlorous acid that is produced when it reacts with chlorine is a kind of disinfection bleacher. ( 8 ) The plant party shall reinforce its management to avoid an improper drain.
In sum, Tongxu County Water Supply Project whose site selection is rational is advanced with design. The pollution control measures either at construction stage or operation stage are effective and feasible, after the application of these pollution control measures, the discharge of pollutants or accidents could

The location of the project is seen in Figure 1- 1. 2. Project Analysis
2.1 Water supply source analysis and selection
2.1.1 Water supply source analysis
(1) Surface water Tongxu county seat belongs to Wohe river water system. There are 7 rivers flowing over it, they are Wohe river, West Branch of Wohe river, Huijiaqu and Xiaoqing River etc., with surface runoff of 68,000,000m3 in total. Both Wohe river and West Branch of Wohe river are big rivers. Demonstrated from the view of centralized water supply, they are inadvisable as the water source of county seat. The reasons are as follows: 3 (!The assurance rate of water supply is small. The total runoff in the dry year is 18,470,000m and there is no flow sometimes according to the testing data of the hydrology department. (2)The water is polluted seriously. Due to the reception of wastewater and sewage from counties in the upper reaches and Tongxu county seat, the quality of water in Wohe River belongs to Category V surface water, It is too seriously polluted to be used as drinking water source. Table 1-1 Project composition and main construction items

The irradiation loop contains: north ring road 20T3 1km. in the north, Xikaifaqu Road west, south ring road south and Dongkaifaqu Road east.
(2) Groundwater According to the FeasibilityStudy Report of Tongxu Water Supply Project Aided by Loan from World Bank(shortened as "FSR") compiled by Henan Project Consultation Company: The water in the district is mainly pore water between the loose petrographic materials. Considering the storing condition of groundwater, water can be divided into shallow water, semi-deep water and deep water according to different geological age, geological characteristics, depth of aquifer, supply condition and waterpower nature. (DShallow water It refers to the aquifer of 40m or so under the earth's surface, which is formed by the alleviation of Yellow River Holocene Series. The rock nature of the upper part is powder sand and powder fine sand, and medium sand with gravel is at bellow level, which forms the typical structure of "dual structures", being thin in upper level and thick lower. The county seat locates the mainstream belt of the Yellow River when it changed its route, with the thickness of 20-25m and general water quantity of 60-100lm3/h. The chemical type of water is HCO3 -Na Ca and the mineralization degree is 0.5g/L. (>Semi-deep water Generally it refers to the aquifer of 40m to 350-500m under the earth's surface formed at the ages of upper, middle and lower pleistocene ages. According to the analysis of electric property to the materials of explored well, its aquiafer floor is at the depth of 470m-480m, which can be divided into the following 3 sections: it is coarse sand with gravel above 140m. It is thin powder sand between this layer and the aquifer of shallow groundwater, and the waterpower connected closely. It is lower pleistocene ages ice water, about 30m, in 140m-320m. The, rock in 320m-480m is composed of the washes in the
2 down section of lower pleistocene ages. Its aquifer is composed of medium sand and medium coarse sand. The depth of utilized sand layer is 60-70m. It can be concluded through the analysis to the measuring well curve that he quality of groundwater in this section is good. )Deep water It refers to the aquifer in the depth of about 5OOm-1OOOm. The depth of nearby drilled sand layer between 40m and 1000m under the surface is hidden in about 40m and 150m below. The water has obvious pressure-bearing quality with the mineralization degree of 1g/L and the temperature above 40 'C.
2.1.2 Supply, runoff and drainage condition
(1) Shallow groundwater The shallow groundwater mainly receives rainwater, side ooze of Yellow River, ooze and leakage of channels, ooze of irrigation, ooze and leakage of pools and supply of runoff. (2) Semi-deep groundwater The groundwater system of semi-deep refers to the groundwater in the aquifer of edio-pleistocene and upper Pleistocene ages. The depth of aquifer roof is 70-80m and the aquiafer floor is buried at 150-170m. It is composed of 3-6 layers of fine gand and medium-sized sand. The total thickness of aquifer is 12.1-46.35 m being regularly thinning from northwest to southeast. The depth of yearly mean water level is generally 12-15m. The specific yield of middling rich water area is 50-60m`/h'm. There is no direct power relationship between semi-deep groundwater and surface water. Its supply source mainly comes from sideway runoff of shallow groundwater. In the.natural condition, the level of semi-deep groundwater is higher than that of shallow groundwater. Because of large exploration, the level of deep medium groundwater decreases and is lower than that of shallow groundwater. Through drilling and in the form of skip flow, the relationship between shallow groundwater and the waterpower of semi-deep groundwater is close, which forms skip flow supply.
2.1.3 Dynamic analysis of groundwater
Through the analysis to the observation materials of water table of many years, the change of shallow groundwater level is affected in natural conditions by hydrology, weather and part agriculture exploration and the dynamic type of groundwater belongs to "ooze-exploration-evaporation". The high water level occurs in July to August and the low water level occurs in May to June. In the artificial conditions, the water level is affected not only by shallow exploration but also by semi-deep exploration and artificial retuming irrigation of groundwater, and the groundwater type belongs to "ooze-exploration". The high water level occurs in April to June and the low water level occurs in August to September. The change of semi-deep groundwater level is affected in natural conditions by the control of local hydrology, and the groundwater type belongs to "supply-drainage". The high water level occurs in July to August and the low water level occurs in November to December. But the high water level occurs between February to March and the low water level occurs in July to August in artificial conditions. (1) Shallow groundwater The shallow groundwater is hidden in 0-70m and the exploration of groundwater is 501,500m3 /year (excluding agricultural water). The water level in the center of funnel decreases obviously. (2) Semi-deep groundwater
3 Aquifer of semi-deep groundwater is hidden in 70-170m. The exploration quantity is 2,945,400 m3/year. The depth of water level in the center of funnel is 14m, and yearly average depth decreases by 0.5m. 2.1.2 Analysis for quality of supply water
The groundwater quality analysis according to FSR is as follows: (1) Physical property of groundwater For its colourless, tasteless and odourless nature, the groundwater in Tongxu County is more suitable to be used as source of living water, process water and agricultural irrigation water. The seasonal temperature change of shallow groundwater is affected by air temperature, temperature of supply source and the decreasing depth of exploration. The water temperature is generally between 15.4-16.1'C. It belongs to cold water, suitable for process water, agricultural water and living water. The highest water temperature occurs in August to September and the lowest occurs in January to February. There is no affection on the temperature of semi-deep water from air temperature. The temperature of semi-deep water is generally in 17-18-C without distinct yearly change. Artificial returning irrigation and the increase of exploration depth etc. are the main factors that affect the temperature of semi-deep groundwater. (2) Chemical property of groundwater (D Shallow water
Shallow water belongs to freshwater with the main chemical type HCO3 - Ca -Mg or HCO3 _C - Mg. North and east from the old city to Hai River and Beigecun Machine Works there is a layer of polluted salt water. 2) Semi-deep groundwater The existing wells in water plant of Tonaxu County are all semi-deep wells. According to the water quality report to pipe water in Tongxu water plant inspected by Kaifeng inspection station of Henan urban supply water quality inspection network in October 2001 in the FSR. the quality type of semi-deep
groundwater in Tongxu County is HCO1 Na, Mg Ca with the moralization of 0.564g/L and total rigidity of 0.206g/L. Through the comparison evaluation of testing results of tap water according to Quality Standard of Groundwater, it is shown that in the 31 analyzed and tested items the index of single component of semi-deep groundwater all reach the water quality standard of type I , II,and III except for the over-proof of total number of the faecal coliform. For the good result of comprehensive evaluation, it is suitable for the source of centralization living drinking water. Therefore it can be drunk as drinking water after disinfections. Through the comparison evaluation of testing results of tap water quality according to Quality Standard of Drinking Water in Water Source, it is showri that: in the inspected items all index of water reach standard I of source water with good water quality, which can be drunk as living drinking water only after disinfections. Through the comparison evaluation of testing results of tap water quality according to Sanitation Norns of Quality of Drinking Water, it is shown that in the inspected items all factors except for colibacillus and residual chlorine meet standard, and the main reason is chlorine is not added before discharging of the water from water plant, therefore, the semi-deep groundwater can be drunk as drinking water only after disinfections.
4 2.1.3 Decision of source and laying type of wells
(1) Decision of source According to FSR of Tonzxu Water Supply ProjectAided by Loan from World Bank compiled by Henan Project Consultation Company.

According to the overall plan of Tongxu county seat, the following two programs of the water supply current situation, selection of source place and water-distribution plant are advanced. Table 2-2 Plan Content Comparative Table Serial Program Content No. The site of plant is located at the cross of Beihuan Road and Jiefang Road in northem county seat. The place, due to its pollution-free source, convenient traffic, good extemal environment that will no produce adverse influence to the sanitation of the water supplied, is planned as I Program I administration district and residential place. What's more, it is near to source place, which shortens the distance of Water transfer pipes and lower the investment by taking advantage of height difference of landform, and it is convenient for future water-distribution as it locates in the planned Site. The site of plant is located at cross of Xingzheng Road and Xikaifaqu Road in southwestevacounty seat with convenient traffic. But the distance to new administration district is long, which is profitless for the future 2 Program Is water-distribution. The poor sanitary condition will affect the operation of water plant. And what's more, the investment cost will be increased because of the long distance to source place and long distance of Water transfer pipes.
According to the demonstration result of the program for Tongxu Water Supply Project FSR, the program I is reconunended because it is deemed in this evaluafion that the scienfific and reasonable plan I with lower investment was in conformity with the overall plan of county seat therefore, the locafion of water-distribution plant is selected according to program I.

3. Analysis for the factor of project pollution
3.1 Producing links of key pollutants 3.1.1 Construction stage
(1) Fugitive dust: The fugitive dust pollution at construction stage individually comes from vehicle transporting construiction material and from in-site cbnstruction and the laying of pipe network. (2) Noise: Noise at construction stage mainly comes from high- noise equipments used during
13 construction such as excavator, pile driver, cutting machine and electric saw etc. (3) Solid waste: Solid waste at construction stage mainly comes from domestic refuse of construction personnel, different kinds of building refuse and waste earthwork. (4) Water discharged after well clean-up: Discharged water is pumped during cleaning up the source well.
3.1.2 Operation stage
(1) Wastewater: Wastewater at operation stage mainly comes from domestic sewage produced by workmen and managerial staff. The production quantity of wastewater is 1440t/a. (2) Wastewater of clean water tank: The wastewater is produced by cleaning up the tank once a year, and the water consumption is 250 t/a. (3) Waste gas: The waste gas at operation stage is thus formed that few unorganized chlorine is dissipated due to the occurrence of running, emission, drop, leakage cases when adding chlorine in chlorinator room. (4) Noise: The noise at operation stage is mainly from the machinery noise which is produced when the water pump is in operation to take or convey water from well source, the maximum source strength value ranges from 80 to 85dB (A) (5) Waste solid: solid waste at operation stage comes from office domestic refuse, with quantity of l5t/a. 3.2 Source intensity analysis 3.2.1 Construction stage
(1) Dust The dust in construction stage respectively comes from the vehicle to transport building materials, the field construction and the laying of pipeline. The pollution concentration mainly relies on wind direction, wind speed and wind strength etc. The key pollutant is TSP. (2) Noise at construction stage considerably come from the those high noise equipments applied at construction, like the excavator, pile driver, cutting machine, electric saw etc. The maximum source intensity value may get to 11 OdB (A) (3) Waste solid: Different kinds of building refuses at construction stage may get to around 500t. During laying piping the earth excavation is 5000 m3 , backfill amount is 4200 m3 and the surplus is 800 m3. The domestic refuse produced by construction staff is less comparatively. (4) Well cleanup and drain: The discharge of groundwater pumped during cleaning up a single source 3 well is about 60m /h. The cleaning period is 2-3 days. There is no pollution with the water, which can be directly used for irrigation of farmland.

1.8 Prediction to water demand
The integrative domestic water demand of county seat, as calculated by prediction, is 43400 t/d in the short term. Since the daily water supply capacity of the existing tap water plant, after maintenance, will be 8000 t/d, the water all the supply capacity of self-service wells of partial manufactories and inhabitants is around 27000 t/d, and of self-service wells in planning area will be stopped in 2005 according to the Notice of the People's Government Tongxu County on The Stop of Self-service Wells in Planning Area of County Seat, the new-increased water demand of Tongxu County shall be 35400 t/d. In light of above analysis results, the water demand size for this project is determined rationally as 35000 t/d.
1.9 Balance of Demand and Supply in Long Term
75900 t/d. In light of the Overall Plan of Tongxu County Seat, 2020 long-term water demand of county seat shall be In The water supply capacity of tap water plant is 43000 t/d, so the new-increased water demand shall be 32900 t/d.
3 the long termn, it cannot meet the urban water demand until a water supply capacity of 35000 t/d is newly increased. 2. Rationality analysis to program selection of water source land In reference to Joint Reconnaissance Report on Exploitation and Mining of Water Source Land of No.2 Water Plant of Tongxu Water Undertakings of Kaifeng City of Henan Province, the water source land is purposed to fall 2 into a 3km area where it is at the north to county seat, west to Wohe River, and east to Tongkai Road (Tongxu-Kaifeng). On the basis of estimation results of reconnaissance, in this area, the water in semideep and deep layers are not affected by air temperature, the annual change is unobvious, commonly 17-18 °C, the water type is HCO3 * -Na, Mg, Ca type, the groundwater mineralization is ordinarily 0.564 g/l, and the total hardness is 0.206 g/l. All the existing wells of tap water plant belong to the semideep-layer well. In light of the Water Quality Report for Pipe Network of Tongxu Water Undertakings as monitored by the Kaifeng Monitoring Station in October 2001, all the single components of semideep groundwater, except for the total coliform group which exceeds the standards, reach the standard Category I, II, III. The result for overall evaluation is good, so it is, suitable for Centralization domestic potable water source. All the test items for deep groundwater reach the top-grade source water Standard, the water quality is good, accordingly the water, only after being treated with disinfection, can be used as domestic potable water. As viewed from the In light of the prediction to the water-level drawdown of exploitation well and the calculation of replenished quantity, we can conclude that the produced quantity 35000 m3 /d of water source land may not only ensure the replenishment, but not affect the agricultural water and the normal use of existing exploitation wells of county seat, it is feasible to daily exploit 35000 m3/d of deep groundwater, which will not cause a comnpetition with agricultural water, in addition, since the underground runoff of deep groundwater is very slow and the groundwater exploitation quantity of deep-layer groundwater within Tongxu County is very little, the deep groundwater is mainly drained via underground runoff into the lower reach, so which is one of the advantages to use deep groundwater. In sum, the water quality of deep groundwater of Tongxu County Seat is good and the water quality is sufficient, which is in favor of the long-term stable supply of water source. After the in-a-lump investment of this project, the operation cost is to be low, the process flow is simple, and the water-source well exploitation means combining the deep groundwater and shallow groundwater together, which is adopted in this project, is in accordance with local conditions. Therefore, the design selection for the water source land of this project is scientific and rational. 3. Rationality analysis to process selection of this project The production of tap water in this project mainly adopts the chlorination which is in general use in domestic, the purpose of sterilization and disinfection is primarily to use the physical or chemical means to kill the pathogenic microorganism in water, so as to prevent from its dangerous to the health of human, livestock and foul, as well as its pollution to ecological environment. In light of domestic production technology and economic condition of tap water industry, most of the tap water plants apply the liquid chlorine as the disinfecting agent, so this means may save cost due to its mature technology, simple process as well as good disinfections The groundwater which is treated as the water supply source in this project is good with quality, if applied with liquid chlorine desinfections, it can satisfy the requirements on the outlet water quality, additionally, this means applied may save investment and save the cost in operation. Therefore, the liquid chlorine for disinfections is thus applied in this project and its process is mature and reliable.
