Bollineni Hillside Phase I in Perumbakkam off Old Mahabalipuram Road sprawls across 45 acres and consists of 1295 dwelling units. For ease of administration, the community is cleaved in the middle, the north side servicing a half of those dwelling units and the south side the other half.

Both segments have a separate STP-WTP unit. These units are eminently useful, but are a criminal guzzler of energy, a fact that sticks out painfully when the EB bill arrives. Sajeev Kumar, president of Bollineni Hillside Residential Township Owners Association (BHRTOA), estimates the community’s monthly electricity bill at ₹10 lakh. “Electricity expense is one of the top three expenses,” he points out.
