St. Louis does not operate a municipal recycled-water network. Greywater reuse on private property is governed by Missouri plumbing code and the city Plumbing Division, and rainwater harvesting for irrigation is allowed under MSD Project Clear stormwater incentives.
Unlike arid Western cities, St. Louis has abundant Mississippi/Missouri river supply and no purple-pipe reclaimed-water system. Title X Plumbing Code adopts the Missouri Uniform Plumbing standards, which allow approved greywater systems for subsurface irrigation if separated from potable lines and permitted. Rainwater cisterns are widely used, and MSD's Rainscaping rebate program co-funds rain gardens and permeable pavers to reduce combined-sewer overflows. Direct potable reuse is not authorized at the city level.
Cross-connecting greywater or rainwater to a potable line without a permitted backflow preventer triggers Plumbing Division correction orders and risks revocation of the building's water service.
