HYDERABAD: With water leakages taking place at regular intervals on Ring Main-I of Krishna Drinking Water Supply Scheme (KDWSP) Phase-II, leading to huge wastage of water and money, the Hyderabad Metropolitan Water Supply and Sewerage Board has proposed online leak detection and preparation of DPR.
Since commissioning of the pipeline, some 45 major leakages and bursting of pipelines took place on RM-1. The HMWS&SB decided to go in for online detection for up to 6,000 mts to ascertain the pipeline condition. It was found that frequent leakages and bursting of pipelines are occurring on the stretch of about 6,000 mtrs from Nandi Hills to Shivaji Chowk at RCI compound.
HMWS&SB has invited Expression of Interest for online leak detection and preparation of detailed study on RM-I of KDWSP Phase-II. The total length of RM-I pipeline from Sahebnagar to Mailardevpally pumping station is about 14 kms and is laid with PSC pipes. HMWS&SB officials told Express that KDWSP envisages tapping of 16.5 tmc of raw water from river Krishna (270 MGD) in three phases.
The treated water is being pumped by three pumping stations at Kodandapur, Nasarlapally and Godakondla on Hyderabad-Nagarjunasagar State Highway to Master Balance Reservoirs at Gungal. From Gungal, the water flows by gravity to Sahebnagar Terminal Balancing Reservoir and is then distributed further.
