Lawn Watering Program

The City of Sioux Falls’ lawn watering program has three stages that take into account water available in the Big Sioux River, the Big Sioux Aquifer, and through the Lewis & Clark Regional Water System. It also uses the daily demand for water to determine how and when we change between stages of conservation.
