AWWA REUSE52108

As the population grows, the demand for water is increasing and stressing potablewater systems. As this demand for potable water increases, use of reclaimed wateris becoming more and more important as an alternative source of water forirrigation. Water reuse is the wave of the future in Las Vegas Valley, Nevada,water management. In order to meet the water demand needs for major water users,the Clark County Sanitation District and the Las Vegas Valley Water District havecreated a water reclamation and reuse project in southwest Las Vegas to providerecycled water to golf courses, schools and parks. One of the major concerns withusing reclaimed water for the golf courses is water quality. Factors which affectthe reclaimed water quality include salt concentrations, dissolved elements,chlorides, and pH. The total dissolved solids (TDS) concentration of thereclaimed water is approximately 1200-1400 mg/L. Excessive concentrations ofdissolved salts in the root zone hinders water uptake for landscape plants andturf, and plants may become water-stressed even though the soil is moist. Inaddition to water quality, the cost of recycled water is also an important aspectof the feasibility of this project. This paper discusses how the $22 millionWater Reuse Facilities are optimized to make recycled water affordable, meet highwater quality standards and remain attractive for large irrigators to use. Thepaper concludes with a discussion of financing issues, institutional complexitiesin the project development, public acceptance, regulatory requirements andbenefits of water reuse. Includes table.
