The Water Authority of Western Australia has proposed that all municipal wastewater from Albany undergo secondary treatment at the Timewell Road (No. 2) plant prior to being piped and irrigated onto trees and pasture at a land disposal site on the outskirts of Albany.

This proposal constitutes part of a long-term plan to rehabilitate the eutrophic Princess Royal Harbour and would result in the removal of the Point King sewage outfall (a significant source of nutrients to the harbour).
