St. Louis has no day-of-week or time-of-day lawn watering restrictions. The city draws abundant supply from the Mississippi and Missouri rivers via the Chain of Rocks plant, so STL Water customers may irrigate without seasonal caps.
St. Louis Water Division (city-owned) treats roughly 100 million gallons daily from two river intakes, giving the metro one of the most secure water supplies in the country. Unlike Western cities, there are no Stage 1-4 drought triggers, no even/odd-address watering days, and no fixed sprinkler windows. Customers pay metered water and sewer charges, and MSD Project Clear assesses stormwater fees on impervious surface. Waste of water — broken sprinklers, runoff into streets — can be addressed under nuisance code if reported.
Visible water waste like sprinklers running onto the street can trigger a nuisance complaint, but routine lawn irrigation is unrestricted.
