Jordan Valley Water uses both surface water and groundwater sources to supply water to its customers:

Surface water ― the majority of the water Jordan Valley Water's customers drink comes from melting snow and rain in the Provo River Watershed. This watershed covers approximately 528,000 acres in Wasatch, Utah, and Summit counties. Snow melts and rain runs off into numerous smaller tributaries and into the Provo River, filling Jordanelle and Deer Creek Reservoirs. This water is treated at the Jordan Valley and Southeast Regional water treatment plants. Several mountain streams along the east bench in Sandy are also treated at the Southeast Regional Water Treatment Plant.

Groundwater ― about 20 percent of Jordan Valley Water's water is supplied from approximately 30 groundwater sources located in deep underground aquifers that are naturally recharged by melting snow and rain. These are located primarily in the southeast portion of the Salt Lake Valley.

Because of our urban environment sources and the recreational activities that occur in our watersheds, the water sources have a low to moderate susceptibility to various potential contamination sources (PCSs). These include leaking underground storage tanks; commercial and residential herbicides; pesticides and fertilizers; agricultural runoff; human and animal activities in the watershed; residential and industrial sewage; and storm water runoff.

To determine PCS impacts, Jordan Valley Water conducted a source water assessment and maintains a Drinking Water Source Protection (DWSP) Plan for all surface water and groundwater sources. This plan identifies source protection zones, PCSs, and management strategies to protect the drinking water delivered to Salt Lake Valley.

Once a source is polluted it can take decades and millions of dollars to restore it to its pristine condition. The most effective protection measure is pollution prevention. You can help protect your drinking water by properly disposing of all household hazardous wastes (i.e. motor oil, paint, pesticides, etc.) and by using recreational areas responsibly.
