  Here’s a scenario that plays out more often than developers admit: a 500-flat project gets its occupancy certificate held up at the pollution control board stage, not because the towers aren’t ready, but because the STP submitted for approval was sized using a per-flat shortcut borrowed from a smaller project. The reviewing engineer runs the numbers, finds the plant is roughly half of what the population and water-consumption figures actually demand, and sends the file back. By then, the plant room is already cast in concrete, too small to expand without tearing into finished civil work. That’s the cost of guessing at a KLD number instead of calculating it, and it’s a mistake that surfaces at the worst possible stage of the project. That’s the real problem with STP sizing for large apartment communities. It isn’t a fixed formula you plug flats into and get a magic number out. It’s a set of engineering judgments, occupancy, water use, peak flow, future growth that, done carelessl...
