Public Health Engineering Department Tender Document for Jawai Project Pkg-V and Cluster -III CHIEF ENGINEER, PROJECT, JODHPUR Including 10 Years O&M CHAPTER-1 PROJECT IN BRIEF 1.1 BACK GROUND The Jawai- Hemawas -Jodhpur Canal conveyance System was in use up to the year 1998 to meet drinking water needs of Jodhpur city, Pali town, five other towns of Pali district and 372 villages of Pali and Jodhpur District. This system was discontinued for Jodhpur city when RGLC water reached in Kaylana impounding reservoir of Jodhpur City in the month August 1998. The 228 villages & 6 towns of Pali district are covered through Jawai Canal System up to Rohat as source from the year 1999. The total average annual losses in open canal were of the tune of approx. 980 mcft as against net water demand of 1204 mcft in the year 2005-06. On an average, nearly 50% to 60% water quantity drawn from Jawai Dam was being lost due to seepage, pilferage and other reasons. Jawai Pipeline Project was framed with the objective to conserve water to enable additional coverage with the water so saved. The villages/towns of Pali district, which are facing acute potable water shortage due to existing ground water source having gone dry or deterioration in quality of water available, are proposed to be covered through this project. Total 333 no. additional villages and 3 no. additional towns of Pali district have been identified for coverage through this project. The A&F sanction of Jawai Pipeline Project was issued by 164th PPC meeting held on dated 25.6.2005 for Rs. 354.73 Crores. Third revised A&F of Rs. 634.79 Crores was issued in 178th PPC meeting held on dated 11.10.2007.The project was divided in five packages to give flexibility to suit cash flow requirements & ease of implementation, as per approval issued in 409th TC meeting dated 5.10.2005. Each package was arranged in such a way that its completion may derive benefits of the investment. Package-wise brief status of Jawai Pipeline project is as follows: Work of Package-1: It is related to work of dead storage pumping from Jawai Dam . It may not be required as dead storage of Jawai Dam has been reduced to about 1/3rd capacity for which present temporary pumping arrangements would be adequate. Work of Package-2: It is related to Transmission Main works from Jawai Dam to Mandli-Pali. Pipeline from Jawai to Pali of size 2000mm to 1100mm MS/GRP in total length of 88Km has been completed and is in use .The pipe line is working as gravity main. Work of Package-3: It is related to Water Supply Distribution Improvement in Pali City and is complete with construction of two OHSR, about 52 Km pipeline and upgradation of three pumphouse in Pali City and is in use. Work of Package-4: It is related to work of pipeline from Pali to Sojat & Rohat and Khod to Kherwa.The work related to Pali-Rohat pipeline ± 37.3 Km, 350/300 mm dia GRP/MS completed and is in use. Pipeline from Mandli (Pali) to Sojat, -45 Km , 800/750/350 mm DI K-7 is completed. Remaining work of package i.e. pipe line from Khod to Kherwa is taken up along with cluster project-II whose tender are under process. Work of Package-5: It is related to Pipeline from Sojat to Raipur- Bar-Jaitaran-Anandpur Kallu-Nimaj and is part of this contract. 01- PROJECT IN BRIEF updated Vol-II 1 Public Health Engineering Department Tender Document for Jawai Project Pkg-V and Cluster -III CHIEF ENGINEER, PROJECT, JODHPUR Including 10 Years O&M 1.2. THE PROPOSED PROJECT AREA : As briefed above the Jawai Pipeline Project is mainly to convey water through close conduit to benefit committed 6 towns and 228 villages as well as additional beneficiaries 4 towns (3 towns of Pali and 1 of Sirohi district) and 333 villages by way of saving/eliminating canal losses. The additional beneficiaries 333 villages and 3 towns of Pali districts are to be benefited by means of framing cluster packages from various outlets of transmission main. Brief of additional beneficiaries i.e. 333 villages and 3 towns of Pali district is being depicted below. Cluster Trunk Main No. of Villages/Towns Remarks Project Segment I Jawai to Sojat 111 Villages & 1 Sanctioned and work is under execution Town since 1st September 2012. II Khod to 82 Villages & 1 Town Sanctioned and work is to be executed for Kherwa and 26 existing which tender already invited. covered villages III Sojat to Bar 133 Villages & 1 Sanctioned and shall be executed along with Jaitaran-A.Kallu Town execution of Package V in this contract. Administrative & Financial Sanction for Jawai Pipeline project Package-V is already available as mentioned above. The Technical Sanction of this Package has been accorded in 587th TC dt. 12.08.2013 for estimated cost Rs. 112.86 Cr. The Administrative & Financial Sanction to Jawai Cluster Project-III for benefitting 133 villages and 1 town Jaitaran of Pali district, comprising work with offtake at SOJAT, 30 MLD WTP and pumping station at Sojat, Chandawal, Haripur, Kalab Kallan, Near Bagari, Bar, Sabalpura, Nimaj, Jaitaran, Ap.Kallu, Lambiya and Balupura along with rising and distribution mains, reservoirs etc. was issued in 190th PPC held on dated 30.05.2013 for Rs. 214.50 Crores. Technical Sanction was accorded to this project by Technical committee of RWSSMB in its 587st meeting held on dated 12.08.2013 for estimated cost Rs.163.07 Cr. As against norms of 70 LPCD laid in the guideline of GoI, the State has decided to supply 55 LPCD water from surface source and rest will be continued through existing ground water based system. So, complete new infrastructure is to be created at Sojat H/W to the benefiting 133 villages and Town Jaitaran. For this purpose 133 villages and one town have been grouped into clusters. Each cluster will have its independent overhead service reservoir (OHSR) from where distribution pipelines are to be laid up to villages of clusters up to the Village Transfer Chamber (VTC) to be developed at each of village to facilitate drawl and metering of water supply. Subsequent management and distribution would rest with the Village Water and Sanitation Committee (VWSC)/Pani Samiti. The scope includes construction of all related works of pumping and transmission system including :DWHU7UHDWPHQW3ODQWV&:5¶V Pumping Stations, Service Reservoirs, Rising and Distribution network up to Village Transfer Chambers, 363¶VZLWK&:7¶VHWFfor the respective water demand of 133 villages & one urban town Jaitaran up to design year 2044. The list of villages now proposed for coverage through Package-V in Cluster Project-III, are tabulated below. The villages/ schemes have been grouped from the point of view of minimum travel of water in pipeline and making optimum use of present facilities available in rural water supply schemes. 01- PROJECT IN BRIEF updated Vol-II 2 Public Health Engineering Department Tender Document for Jawai Project Pkg-V and Cluster -III CHIEF ENGINEER, PROJECT, JODHPUR Including 10 Years O&M Abstract of Offtake wise Villages/Towns to be covered in water supply network is as follow: TABLE NO. 1.1 DESIGN POPULATION DESIGN DEMAND NAME OF OFFTAKE NO.
