For Hence, there will be no alteration to natural drainage system. m 1 A 1.6 What are the quantities of earthwork involved in the construction activity cutting, filling, reclamation etc. (Give details of the quantities of earthwork involved, transport of fill materials from outside the site etc.).
It is estimated that approx. 20,000 m3 of earth material will be excavated during initial construction phase for foundations, basement. 80-90% of excavated material will be re-used for road construction and landscaping. Very little cutting, filling and reclamation etc. will be done as the site is fairly plain with an average elevation of 80 m. The soil excavated during construction will be first temporarily stored in an area earmarked and then shall be used for backfilling, landscaping & road construction and rest of the soil shall be transported to the designated disposal site in tune with the local norms. Proper drainage system will be provided to deal with the storm water in case of rain during construction.
1.7 Give details regarding water supply, waste handling etc during the construction period. Water Requirement (Construction Phase): ~ 12 KLD Source of water: Treated water from CSTP supplied through hired tankers will be used during construction. Construction Debris (Bricks, Cement, Concrete and Mortar) generated will be reused in road construction, backfilling and leveling, spare debris (if any) will be disposed off as per the norms. Ready mix concrete will be used for construction on site. The fertile top soil will be scrapped, separately stored and reused for horticultural purpose. Spillage of oil from the machineries will be properly collected and disposed off. Proper Sanitary facilities and wash area will be provided and good hygienic conditions will be maintained throughout the construction phase. Approx 100 workers will be hired till the project completion. Solid waste generated = 100 x 0.25 kg/ capita/day = 25 kg/day Water Requirement during construction: Fresh Water- 12 KLD Septic tank/soak pits with mobile toilets shall be provided to take care of waste water generated from site (labor camps and site office) Domestic solid waste generated will be managed as per MSW (M & H) Rule 2016.

For 1.8 Will the low-lying areas & wetlands get altered? (Provide details of how low lying and wetlands m 1 are getting modified from the proposed activity). A
There is no low-lying area & wetlands in or near the project area . A nallah is flowing North East of the project along the boundary wall while the river Ganga is at a distance of 16 km south east of the project. 1.9 Whether construction debris & waste during construction cause health hazard? (Give quantities of various types of wastes generated during construction including the construction labour and the means of disposal)
Wastes which will be generated during the construction phase include the following: Excavated materials from earthworks (e.g. cuttings, basement excavation, foundation etc), General construction waste (e.g. wood, packing material, scrap metal, concrete and empty cement bags); Hazardous wastes generated by general site practices e.g. vehicle, plant maintenance/servicing and paints, solvents and varnishes. Municipal wastes generated by site workers. Most of the construction waste will be reused in road construction and surplus will be sold to recyclers.
Excavated Materials from Earthworks It is estimated that approx. 20,000 m3 of earth material will be excavated during initial construction for foundations & basement etc. Maximum percentage of excavated material will be re-used within premises for different purposes. The excess earth would only be the construction wastes and will not cause any health hazards.
Municipal Waste & Other waste Municipal wastes comprise food wastes, packaging and waste paper. Generation rate of solid waste from labour colony will vary from place to place due to habits and living condition. Approximately 0.25 Kg/capita/day of municipal waste may be expected during construction phase. The domestic waste water generated from construction camps shall be disposed off through septic tank / soak pit or mobile toilets with STP/ municipal sewer. Some amount of debris, cuttings and construction materials may be observed at construction site. However the quantity of their waste materials would be very small and limited up to the construction site only.
11 Proposed Affordable Housing “Sai Gaon”. Form 1 at Village- Luchchepur Kazi Sarai, Babatpur Road, Varanasi, Uttar Pradesh
For Contamination by these wastes would be negligible and would be collected time to time during m 1 construction phase and disposed off accordingly. A The Impact on soil during construction phase will be marginal and reversible in nature.

2.7 Give details of the water requirements met from water harvesting? Furnish details of the facilities created.
Water harvesting pits have been proposed for augmentation of ground water. The rainwater collected from the rooftop will be conveyed into the rainwater harvesting system consisting of Desilting-cum-filter Chamber, oil and grease separators and borewells for recharge into the groundwater. RWH will be initially
16 Proposed Affordable Housing “Sai Gaon”. Form 1 at Village- Luchchepur Kazi Sarai, Babatpur Road, Varanasi, Uttar Pradesh
For done only from the roof top. Runoff from green and other open areas will be done only after permission m 1 from CGWB. No demand will be met from the process. A Analysis of the observed data on intensity duration of rainfall of past records over a period of years in the area is necessary to arrive at a fair estimate of intensity-duration for given frequencies. The longer the record available, the more dependable is the forecast. In Indian conditions, intensity of rainfall adopted in design is usually in the range of 15 mm/hr to 40 mm/hr. The intensity of precipitation for design of drainage scheme has been taken as 40 mm/hr. Table 8: Calculations for storm water load Peak Run off Max, Rainfall Intensity 40 mm/hr Location Runoff Area m2 Rainfall Peak Run off Coefficient intensity in m3/hr (in m) Roof Area 0.8 2247.06 0.04 72 Paved area 0.6 5476.62 0.04 131 Green Area 0.2 2474.64 0.04 20 Total Runoff m3/hr 223
Total Runoff = 223 m3/hr Roof top runoff= 72 m3/hr Taking 15 minutes Retention Time, Total volume of storm water = 223/4= 56 m3 Particular Size Volume Desilting Chamber 5.0 m x 1.75 m x 2 m 17.5 m3 Recharge Pit 2 m x 1.75m x 1.5 m 5.25 m3 Total Effective Volume 22.75 m3
Total Effective Volume of a pit+ Chamber = 22.75 m3
Hence No. of pits required = 56 / 22.75 = 2.46 pits or 3 pits No. of Pits Required for Roof top rainwater harvesting: Roof top Runoff = 72 m3/hr Taking 15 minutes Retention Time, Total volume of storm water = 72/4= 18 m3 Hence No. of pits required = 18 / 22.75 = 1 pit No. of pits provided: 3 pits
Note: RWH will be initially done only from the roof top. Runoff from green and other open areas will be done only after permission from CGWB.

For 2.8 What would be the impact of the land use changes occurring due to the proposed project on the m 1 runoff characteristics (quantitative as well as qualitative) of the area in the post construction A phase on a long-term basis? Would it aggravate the problems of flooding or water logging in any way? Since this is a group housing project, the paved area will increase thus the land surface will change thereby increasing the run off during rains. Maximum storm rainfall of 40 mm has been assumed on the past experience. No adverse impacts are envisaged due to proposed project on the run off characteristics of the area as adequate arrangements have been made to trap the rainwater and suitable storm water drainage system has been provided.
There will be change in the surface run off coefficient in the pre construction phase and post construction phase. The surface run off will be captured and used for harvesting so that the ground water level is consistent. The storm water drains will be cleaned in the pre-monsoon phase so that the water logging will be avoided.
During the post-construction phase, runoff from the project shall not be allowed to stand and create water logging or enter into the road side or nearby drain. Adequate measures shall be taken to collect such run off and either shall be reuse or stored in recharging pits. Suitable garlanding drain as per the existing contours of the plot will be developed. The project will not aggravate the problems of flooding or water logging in any way, as the topography is plain.
2.9 What are the impacts of the proposal on the ground water? (Will there be tapping of ground water; give the details of ground water table, recharging capacity, and approvals obtained from competent authority, if any).
There will be no impact on the groundwater as no water abstraction is proposed during construction or operation. Groundwater will be recharged further as rainwater harvesting is proposed in the project. The rain water collected from roof top, will be sent for ground water recharging through 1 no of RWH pits. 56 m3/hr of water is available for ground water recharge which will be recharged through RWH pits. A major part of the area is under green or open land which will percolate naturally and augment the ground water. Therefore, most of the rain water will be directly infiltrated through these open/green areas.
18 Proposed Affordable Housing “Sai Gaon”. Form 1 at Village- Luchchepur Kazi Sarai, Babatpur Road, Varanasi, Uttar Pradesh
For Hence no adverse impacts are envisaged due to the project on the ground water quality and the level. m 1 Maximum recharging of the underground aquifer will be done to improve the water table. A As per hydrogeological investigations carried out by CGWB, there are no high yielding open wells around site. The ground water structures by which groundwater are exploited is tube wells only. The exploratory tube wells around premises have good yield up to the end of winter and during summer there is a drastic fall in water table.
2.10 What precautions/measures are taken to prevent the run-off from construction activities polluting land & aquifers? (Give details of quantities and the measures taken to avoid the adverse impacts). Effective measures will be adapted to reduce the storm water run-off from the construction site- . Ensuring vehicles stick to the access track. . Cleaning all mud and dirt deposited on roads from construction-related activities. . Excavation work will not be carried out during monsoon season. . Constructing a fence around the site to trap sediment whilst allowing water to flow through. . Diverting up-slope water with turf and not mixing mortar in locations that will drain into storm water system. . Preventing wastewater from brick cutting activities and stockpiles entering the storm water system. . Construction material will be stored in temporary shed at the earmarked place and will be covered ensuring that no leach ate or spoilage of land occurs. . Curing water will be sprayed and, after liberal curing, all concrete structures will be painted with curing compound & covered with gunny bags, then the water will be sprayed.
2.11 How is the storm water from within the site managed? (State the provisions made to avoid flooding of the area, details of the drainage facilities provided along with a site layout indication contour levels).
Since the existing topography is congenial to surface disposal, a network of storm water pipe drains has been planned adjacent to roads. All building roof water will be brought down through drain water pipes. Proposed storm water system consists of pipe drains, catch basins and seepage pits at regular intervals for rain water harvestings and ground water recharging. The storm rainfall of 40 mm/hr. has been considered for designing the storm water drainage system. The storm-water drains will be cleaned in the pre-monsoon phase so that the possibility of the groundwater pollution & water-logging can be minimized / avoided.

For Detailed storm water management plan will be implemented and regular inspection and cleaning of drains m 1 will be carried out. A
2.12 Will the deployment of construction labourers particularly in the peak period lead to unsanitary conditions around the project site (Justify with proper explanation).
Locals will be preferably employed during the construction phase. There will be no stagnant water at site, as the run-off from the relevant areas will be systematically drained. The civil contractor will be made responsible for site sanitation and will be bound by the management to adhere to healthy level of sanitation. All sanitary and hygienic measures will be provided and maintained throughout the construction phase such as: Provision of separate toilets for the construction workers. Septic-tank followed by soak-pit will be provided for effluent treatment. Litter bins will be provided for biodegradable waste.
2.13 What on-site facilities are provided for the collection, treatment & safe disposal of sewage? (Give details of the quantities of wastewater generation, treatment capacities with technology & facilities for recycling and disposal).
During Construction Phase Septic tank with soak pit or mobile toilets and municipal sewer shall be provided to take care of waste water generated from site (labor camps and site office). Domestic solid waste generated will be managed as per MSW (M & H) Rule 2016.
During Operation Phase Sewer network will be laid for collection of sewage. Approximately 156 KLD waste water will be generated from the project which will be treated in the State of Art design STP of 200 KLD capacity and the treated water will be utilized within site for different purposes (Flushing, Landscape development & other low end uses). Spare treated water (upto Secondary Treatment) shall be discharged into municipal sewer. The sludge from the STP will be disposed along with municipal solid waste.

Total landscaped area proposed for project is 2474.64 m2. A combination of evergreen and ornamental flowering trees, palms, shrubs and ground covers will be planted along the sides of the roads and in open spaces & sat back area within the complex. Landscaping is an important element in altering the microclimate of a place. Proper landscaping reduces direct sun from striking the buildings and heating up building surfaces, prevents reflected light carrying heat into a building from the ground or surfaces, creates different airflow patterns and can be used to direct or divert the wind advantageously by causing a pressure difference. Shade created by trees and the effects of grass and shrubs reduce air temperature adjoining the building and provide evaporative cooling. A study shows that the ambient air under a tree is 20C to 2.50C lower than that for adjacent un-shaded areas.
Parks & Avenue Plantation Ornamental trees with spreading branches, shade giving with colorful flowers for people to relax and suitable patches of lawns, rockery with cactus and other small flowering xerophytic plants shall be planted.
