Non-Potable Water For New Development

Non-potable water is raw-untreated water that originates from mountain snowpack and is not of drinking water quality. Greeley uses non-potable water for irrigation and return flow obligations to comply with Colorado water law.

Greeley has been using non-potable water for irrigation since 1870, delivered through a large network of ditches and laterals running through the city. Most city parks and golf courses are already served by non-potable water. Expanding use of non-potable water is a city priority as it decreases the need for treated. It is an important component in Greeley’s water future. The city completed a non-potable master plan in 2021 which provides a 5- and 20-year plan for capital projects for improving and expanding the system. The city encourages non-potable irrigation for commercial and residential development. Non-potable water is approximately 30% less than potable water.
