The Christchurch Wastewater Treatment Plant (CWTP), also known as the Bromley sewage plant, is the main wastewater treatment plant of Christchurch, New Zealand. It is located in the suburb of Bromley, adjacent to the Avon Heathcote Estuary. Opened in 1962, it replaced an earlier sewage disposal farm that had operated since 1882. In late 2021, two trickling filters burned down and adjacent suburbs have since been subjected to a putrid smell.
