New golf courses will not be approved in Washington County unless developers can prove the use of their own nonpotable water for irrigation. This was one of new water restrictions announced by the Washington County Water Conservancy District on Wednesday. The largest cities in the county have banned non-functional grass for commercial and and industrial developments, and have limited the amount of grass that new homes can have. The new ordinances also require the use of untreated and reuse (treated wastewater) where available for outdoor irrigation use. Currently, the use of these types of water is being used for parks, schools, golf courses and city owned facilities. Other restrictions announced include the limiting of water use by car was facilities, and calling for appliances in the county to be Energy Star certified. The Washington County Water Conservancy District is projecting that the new ordinances will save nearly 11 billion gallons of water over the next 10 years.
