Tailoring Irrigation Water from Municipal Reuse Facilities for High Value Crops
The high total dissolved solids (TDS) in the effluent applied to golf courses is affecting the turf quality. Alternative solutions will be examined for sustainability and economics.
Need and Benefit
The Stadium Golf Course and the Tournament Players Club (TPC) of Scottsdale, Arizona are the locations of this research study. The TPC and the Desert Course are recreation facilities on government (Reclamation) land that was purchased for the Central Arizona Project (CAP). The golf course industry brings approximately two billion dollars annually to the State of Arizona's economy. The Phoenix Open Golf Tournament brings fifty million dollars locally. The Arizona Department of Water Resources (ADWR) has required the City of Scottsdale golf courses to convert from CAP water use 100 percent effluent on golf course turf. The salinity in effluent used on turf has created problems.
It is our mission to manage, develop and protect water and related resources in an environmentally and economically sound manner in the interest of the American public. The benefit of this research has significant economic impacts for the augmentation of water supplies and the local economy. We will focus on research and development to improve and increase reuse water on turf-related projects.
Under the Reclamation Recreation Act, Title 28, there is a Federal responsibility to provide opportunities for public recreation at Federal Water Projects. This federally owned land was purchased for the Central Arizona Project (CAP) and the land is currently deriving revenue from its success as a turf facility. However, turf sustainability is in question, due to the water quality of CAP water and effluent.
Under the Reclamation Wastewater and Groundwater Studies and Facilities Act, Title 16, we are directed to undertake a program to investigate and identify opportunities for reclamation and reuse of municipal, industrial, domestic, and agricultural wastewater (CAP water), and naturally impaired ground and surface waters, for the design and construction of demonstration and permanent facilities to reclaim and reuse wastewater, and to conduct research, including desalting, for the reclamation of wastewater and naturally impaired ground and surface waters. Salt in the waters has become a very serious issue in the Western United States.
This project will also advance the following Research and Development Output Areas:
* WS2 Desalination and Water Purification Research Program. Of the eight emphasis areas noted for WS2, we are focused on partnerships, economic improvements, reuse, and technology transfer.
* WD4 Water Quality. Develop and improve tools, models, and methods for managing water quality issues that impact operations and deliveries.
