Saint Paul has limited recycled-water infrastructure but allows rainwater harvesting and graywater reuse under Minnesota Plumbing Code, with SPRWS pilots exploring non-potable reuse for parks irrigation.
Saint Paul lacks a citywide purple-pipe reclaimed water system. Residents may harvest rainwater in cisterns and rain barrels for outdoor irrigation, and limited graywater reuse from laundry and showers is permitted with proper plumbing-code permits and a Minnesota Department of Labor and Industry-approved system. Como Park Zoo & Conservatory uses captured rainwater for non-potable plant care. SPRWS partners with watershed districts on stormwater reuse pilots that irrigate parks and athletic fields rather than discharge to the Mississippi River.
Unpermitted graywater plumbing can trigger building inspector orders and fines. Cross-connections between reuse and potable systems are serious code violations subject to mandatory correction and possible criminal charges.
