Mantra, Balewadi, Pune

A residential project on a 16,700 sq m plot at Balewadi, on the Mula river side of Pune, with three towers of four basements, ground, podium, 30 floors and an amenity floor at 107.5 m, a separate shopping block of four basements, ground and two floors, and a club house. There are 377 homes, 32 of them inclusive-housing flats in the second tower, and 8 shops, for an estimated 2,375 residents. The architecture is the architect's. Our work is everything that has to run inside it: the electrical supply and backup, the water, fire, sewage and storm systems, and the green provisions the environmental clearance asks for, all issued in 16 submissions between July and October 2026.

Power: we built up the load from every flat, shop, lift and pump - 6,310 kW connected and 2,976 kW of maximum demand - and from it sized four transformers (three of 1000 kVA and one of 630 kVA), two 625 kVA diesel sets for the residential lifts, pumps, fans and flat lighting, and a 320 kVA set for the shops, with the room, clearances and weights the structure needs. Water: a 304.8 kL daily demand split into fresh and treated water, underground and terrace tanks for each use, and downtakes with pressure-reducing valves so the top floors and the low floors see the same pressure. Fire: a 450 kL tank, 100 kL on every tower roof, a riser in the fire shaft with a flow switch and a test-and-drain valve on every floor, and sprinklers inside the flats. Sewage and drainage: a 280 KLD MBBR plant that returns about 100 kL a day to flushing and gardens, 12 recharge pits, and pumped sumps with a standby pump in the basements. Green and safe: charging for 30% of the bays - 303 car points, 10 fast DC chargers and 87 two-wheeler points, 1,795 kW connected - 125 kW of solar panels and 27,975 litres a day of solar hot water, which with efficient lift drives and pumps and lighting timers save 20.74% of the energy, and lightning protection with chemical earthing pits. Inside the flats: sunk slabs, sleeves, pipe routes, switch and socket schedules and air conditioner points checked against the structure before each slab is cast.
