Keshavpuram drinking water project in full flow

Hyderabad: Summers in Hyderabad were once synonymous with drinking water shortage woes, serpentine queues at public taps and protests in front of the Hyderabad Metropolitan Water Supply and Sewerage Board’s (HMWSSB) office at Khairatabad.

Three summers have passed since the Telangana government came into power and unlike in the past, such scenes are rare. Thanks to abundant rains and advanced planning, drinking water availability in summer is no more a major concern for Hyderabadis.

But not ready to be content with this, the State government is constructing a 10 TMC capacity reservoir at Keshavpuram on the city fringes to meet the drinking water needs of the city in future. Planned at a cost of over Rs 4,300 crore, it will take about three years for the project to be completed.

Chief Minister K Chandrashekhar Rao had specifically instructed the Board to plan projects with an eye on future requirements. With the city expanding rapidly, the drinking water demand will increase further and the Keshavpuram reservoir will cater to this demand, said HMWSSB Managing Director M Dana Kishore.

The project is making steady progress, with the HMWSSB already issuing tender notifications for construction of the reservoir. As per rules, the company that bags the tender will have to attend to and fix any defects in the project for two years from the date of completion.

The project involves formation of earthen bund reservoir at Keshavpuram, construction of concrete block consisting of spill way block, intake structures, Raw Water filling arrangement from Kondapochamma Sagar Reservoir and scour sluice structure, inlet and outlet sluice arrangements, service roads on top and around the bund etc.

A raw water gravity pipeline of 3600 mm diameter will be laid from Kondapochamma Sagar (Pamulaparthy) to the Keshavpuram Reservoir. Raw water drawal arrangements from Keshavpuram Reservoir to the Water Treatment Plant will be made, besides construction of a 750 MLD capacity WTP at Bommarasipeta.

The plan
– Construction of clear water reservoir, pumphouse & electro-mechanical equipment at Bommarasipeta WTP.
– Pumping mains of 3,000 mm diameter will be laid from WTP at Bommarasipeta to proposed Master Balancing Reservoir (MBR) at Ghanpur.
– Construction of 80 ML capacity MBR at Ghanpur including MoM of all reservoirs

Project will be ready in 3 years: Board MD

The HMWSSB is on fast track since the last couple of years. Taking up new projects and extending services to more areas in the city, the Board has been introducing new initiatives like mini jetting machines, Cured-in-Place Pipe (CIPP) technology for repairing old pipelines and so on.

HMWSSB Managing Director M. Dana Kishore tells us what is happening.

Q: A 10TMC capacity new reservoir is being planned at Keshavpuram. What is the progress?

A: It is being constructed to meet the drinking needs of Hyderabad. The estimated cost of the project is over Rs 4,000 crore and it is in the tender stage. The project will be completed in three years.

Q: What is the status of the water supply project to 183 villages within the ORR?

A: The 70 MLD-capacity project aids in water supply to 183 villages beyond GHMC limits and ORR. As part of the project, 190 reservoirs are to be constructed and works pertaining to 104 reservoirs have commenced. Though the entire project will be completed by November 2018, water supply to some areas will begin from February.

Q: By when will the HUDCO-supported Malkajgiri project be completed?

A: The project will be completed by end of December. Nine reservoirs have to be constructed and four ready are for inauguration and works on the rest are on at a brisk pace. Over 30,000 new connections are to be issued under the project and except for 500 connections, rest have been issued.

Q: Any plans to construct more STPs?

A: At present, HMWSSB is equipped with 750 MLD STP capacity. Works are on to enhance capacity by 700 MLD. In a couple of months, tenders will be floated for four STPs along the River Musi and four along the nalas in the core city to treat and recycle water.

Q: HMWSSB had plans to extend sewerage connectivity to fringe areas. What is the progress?

A: At present, sewerage connectivity is confined to the core of the city. In the peripheral areas, the sewerage network is being handled by GHMC and efforts are on to prepare a master plan for the peripheral areas. Shortly, Expressions of Interest will be floated for the master plan and it should be ready in three to four months.

Q: How is the performance of the mini jetting machines?

A: Sewerage-related complaints have come down by 70 per cent after introduction of mini jetting machines. Many other cities too are planning to procure these machines as they are coming in very handy to address sewage overflowing issues in colonies where conventional machines have limited access. GHMC too is planning to buy 50 mini jetting machines to address such issues in peripheral areas.
