This document outlines the wastewater management and treatment system, including sources from staff accommodation, canteen, laundry, and offices. It details components like grease traps, gravity collection networks, pump stations, and treatment systems for grit removal and sludge treatment. The system employs moving bed bio-reactors (MBBR), sand filtration, and hypochlorite injection for effective water treatment. Efforts to recycle water for landscape irrigation and sports field maintenance are highlighted, alongside monitoring and compliance measures to ensure environmental standards are met.
