SUSTAINABLE WATER SUPPLY PLAN-2040 FOR LUCKNOW CITY

摘要

The municipal water supply situation in Lucknow is considerably better because of the availability of local groundwater resources from the perspectives of resource availability, financial sustainability, but environmental benefits, yet is mostly taken for granted and not taken fully into consideration in technical and financial water supply planning. Shifting groundwater supply (from existing 47.90 % to 25%) to surface water supply (increased from existing 52.10 % to 75%) means demand of 1001 MLD surface water by 2040 from current 575 MLD (2014), a gap of 426 MLD has to come from augmenting Gomti river flows by canal systems off- taking from Sarda and Ghagra rivers to guarantee the availability of 500 MLD surface water additionally in all seasons for existing and new proposed Water Works. This paper explores merit and demerit of various options to augment Gomti river flows namely- (i) lifting of water from Ganga river at Lav-Kush barrage Kanpur, 80 km away; (ii) pumping water from Ghagra river at Elgin bridge Barabanki,60 km away; (iii) lifting water from Sarda Sahayak Feeder at km 65 to Kheri branch (11km pipe) through Munderi escape to Gond-Sarayan (tributaries) to Gomti river, (iv) lifting water from SS Feeder km 104.0 (27 km pipe) connecting Ateria escape of Kheri branch to Gomti river; and (v) by gravity flow connecting SSF km 140.78 by 20km pipe line directly to Gomti river, near bridge at Lucknow-Sitapur Ring Road. Gomti River as analyzed in option (v) and UP Jal Nigam have been directed to prepare DPR for upcoming Water Works at Alambagh and Indira Nagar.
