Cooling Tower Make-up: Cycles of Concentration, Blowdown, Drift Loss
A 200 TR cooling tower in an Indian summer evaporates roughly 35 m³/day of water — most of it cooling the chiller condenser, the rest carried by drift and dust loading on the tower fill. Make-up water Read more →

Greywater Recycling System Design: NBC 2016 + LEED + IGBC Compliance
Greywater is the wastewater from baths, lavatories, kitchen sinks, and washing machines — distinguished from blackwater (toilet, urinal). It accounts for 50-80% of a building's wastewater volume. With Read more →

Soak Pit & Recharge Pit Design: Sizing per IS 16636 + NBC for Site Stormwater
A soak pit absorbs storm water (and sometimes greywater) into the soil. A recharge pit recharges groundwater through deeper, larger-diameter design. Both serve as on-site stormwater disposal — require Read more →

Plumbing Vent Pipe Sizing: NBC 2016 + IPC 2018 + Loop / Wet Venting Strategies
A plumbing system without proper venting traps will siphon. Trap-seal loss = sewer gas in occupied spaces. The vent system pressurizes the drainage piping so siphonage cannot occur. Sizing the vent pi Read more →
