: With Telangana government deciding to give top priority to the Information Technology Investment Region (ITIR) in Hyderabad which will become economic backbone of Telangana, Hyderabad Metropolitan Water Supply and Sewerage Board (HMWS &SB) has prepared draft proposals for water and sewerage system for the upcoming ITIR project.
The estimated daily water demand required for the ITIR area would be around 452 million litres per day (MLD). For dealing with 359 MLD sewerage and sullage generation, sewerage treatment plant and sullage treatment plants have been proposed.
ITIR is a self-contained integrated knowledge clusters for growth of IT and electronic hardware manufacturing in 49,9120 acres in and around Hyderabad.
Under the mega project, special economic zones (SEZs), industrial parks, free trade zones, warehousing zones and export-oriented units would come up five Zone I-Cyberabad and surrounding areas in 86.7 sq.km, Zone II-Shamshabad International airport and Maheshwaram 79.2 sq.km, Zone III-Uppal and Pocharam 10.3 sq.km, Zone IV-ORR Connector from Cyberabad to Shamshabad International Airport area 11.5 sq.km, ORR connector from Shamshabad International Airport area to Uppal, Pocharam-14.3 sq.km, all totaling 202 sq.km.
The water board officials told Express that the estimated daily water demand required for the ITIR area would be around 452 MLD, of which 195 MLD is potable water and the remaining 257 MLD is non-potable water. The requirement of potable water will be serviced from the storage reservoirs and the non-potable water through recycling.
The sites for elevated level surface reservoirs (ELSRs) have been suggested at Hardware Park, Hitech city, Pocharam/Uppal Industrial area, Mankhal, Shamshabad, Nadergul and at the central squares of the respective sector clusters in Shamshabad International Airport area. A major service reservoir has been planned at Mangalpally, Nagarjunasagar Highway and Sardarnagar.
Underground sumps along with overhead tanks, ELSRs and water treatment plants would be planned at strategic points for efficient water supply and drinking water would be connected with this pumping system with adequate pipelines. Water balancing will be done taking into consideration potable and non-potable water requirement and availability of treated water, they added.
A water pumping station is also planned for pumping clear water from the underground tank to respective overhead tanks. ELSRs would be proposed to cater to the entire ITIR and the size being in proportionate with the demand.
A gridiron system of pipe network is recommended for the proposed water distribution network.
Within the gridiron system of pipe network, all primary and secondary mains will be looped and interconnected.
Sewerage System: As the sewerage and sullage discharge would be around 359 MLD, sewerage treatment and sullage treatment plants, domestic sewerage network, sullage network and sewage pumping stations were proposed at the Raviral Cheruvu and central squares of the sector clusters, and near Mangalpally at Nagarjunasagar Highway.
