Due to the location and climate of Phoenix, the city has developed a diverse portfolio of water sources to meet the cities needs. These sources include the Salt River Project (SRP), Central Arizona Project (CAP), reclaimed water, and groundwater from the cities wells.
The Central Arizona Project (CAP) delivers water 190 miles from Phoenix at Lake Havasu through a system of canals. The CAP system uses a series of pumps and integral storage reservoirs at Lake Pleasant. Over 1.8 million acre-feet of water is carried each year and accounts for 20% of Phoenix's water. The Salt River Project (SRP) transfers water from the Verde and Salt River watersheds using a system of six dams, 1,300 miles of canals and 255 high-capacity wells. The SRP accounts for 50% of Phoenix's water. The final 30% of the city's water comes from wells and recycled water.
By insuring Phoenix's water supplies are diversified, the city can plan for future growth and adequately handle shortages. In recent years arsenic and potentially carcinogenic disinfectant byproducts have exceeded health guidelines.
