Aaiji Developers Residential Project, Balewadi

A residential building by Aaiji Developers at Balewadi, in north-west Pune: a basement of parking, a ground floor and thirteen residential floors with a terrace, holding 65 three-bedroom flats of about 98 to 105 sq m carpet area - five on each floor - for an estimated 325 residents, served by three lifts. Flats of this size carry air conditioning and heavier appliances, so each takes a three-phase supply. The architecture is the architect's; our scope is the MEPF design.

We prepared the calculations in July 2026. Power: every flat at 75 W per sq m of carpet area, three 15 HP lifts, the domestic, drinking-water, booster, sewage, sump and sub-soil pumps, the water treatment plant and organic waste converter, basement ventilation and staircase pressurisation, street lighting and EV charging for 20% of the 57 car bays - 11 chargers of 7.2 kW - for 673 kW connected and 332 kW of maximum demand: 369 kVA, or 443 kVA with a 20% margin, on a 630 kVA transformer, with 68 three-phase connections - 65 flats and 3 common - grouped floor by floor on four meter panels; and a 100 kVA DG set for the lifts, pumps, ventilation and common lighting at 80% diversity. Water: 325 residents at 135 litres a day - 115 litres of domestic and 20 litres of drinking water on separate pipes - 43.88 kL a day, with underground tanks of 38 kL domestic, 19 kL raw and 10 kL drinking water and a 75 kL fire tank, terrace tanks of 38 kL domestic, 7 kL drinking and 20 kL fire, and 39.49 kL a day of sewage to a 40 KLD treatment unit.
