For maintenance of big real estate ventures that have lot of greenery, it is difficult to get water. With municipal water supply limited and groundwater resources scare, it is difficult to nurture the greenery. In view of the dependence on groundwater, it is equally important to take measures for recharge. Parks and avenue plantations in such ventures help recharge groundwater.

To overcome the problems it is ideal to have a sewage treatment plant (STP) on the premises. The idea occurred to Suresh Bavineni, Director of VPL Projects of Vizag Profiles Group, when he visited luxury tourist resorts in hilly or far flung areas where there is no municipal sewage treatment and such plants are in use.

Picking up on the idea, he decided to implement it in Green City near Apparel Park at Vadlapudi. He got the equipment for the STP with 1.6 lakh litre capacity from a Chennai-based company and got it installed. “This is not a mandatory requirement for the project but we decided to do it as a conservation move and it is our effort to save water,” declares Mr. Suresh. No project in the city has it so far, he says.

The sewage from the villas with an extent of three lakh sft is collected in a sump and after treatment is pumped into another sump.

About one lakh litres of water is collected in the sump with about 70 per cent of the 100 villas occupied. However, the water treated depends upon the use in the villas, he says.

The water is used for wetting the park and avenue plantations in Green City. About Rs.50,000 is spent on maintenance of the STP. However, unless the real estate venture is reasonably big, it is difficult to maintain it, he points out. Though it is not mandatory setting up such plants and maintaining them totally depends upon the commitment of the residents’ association, he says.
