The policies described herein are in the best interest of the City of Airway Heights. This chapter is necessary to protect the water supply of the region, which is vital to public health and safety, and to prevent endangerment of public and private property. Developing and utilizing reclaimed water can reduce the need for additional potable water. In light of these circumstances, certain uses of potable water may be restricted where reclaimed water is available or production of potable water is unduly impaired. To encourage the use of reclaimed water in lieu of potable water the City desires to sell the reclaimed water. (Ord. C-717 § 2, 2010)
13.10.020 Water reclamation policy.
