§ 5.10. Water reuse/recycling.

Las Colinas is a twelve thousand (12,000) acre, master-planned development located within the City of Irving. The development includes four (4) golf courses, luxury hotels, office buildings, and exclusive residential areas. A major feature of the Las Colinas development includes extensive waterways, lakes, and landscaped areas.

The Dallas County Utility and Reclamation District (DCURD) provides nonpotable water to the Las Colinas development. This nonpotable water is used for irrigation of the four (4) golf courses, offices, street medians and open spaces; and evaporation make-up water for various lakes and waterways within the development.

The nonpotable water supplied by DCURD is a combination of surface water from the Elm Fork of the Trinity River and reclaimed wastewater purchased from the Trinity River Authority's Central Regional Wastewater Treatment. DCURD has a contract with TRA to purchase up to eight thousand (8,000) acre-feet per year (7.14 million gallons per day) of treated wastewater effluent. During the past five (5) years, the amount of reclaimed wastewater used by DCURD for nonpotable use has averaged over one million (1,000,000) gallons per day.

It is anticipated that future development within parts of Las Colinas will continue to use reclaimed wastewater for irrigation and evaporation make-up water. In addition, Irving recently completed a "Recycled Water Implementation Plan" and will be pursuing authorization to start a new direct reuse system to serve additional customers with reuse water.
