The Murray Water System provides potable water to the City of Murray and portions of Calloway County. The water system serves approximately 8,000 customers, including several outlying water districts. In 2021, the water treatment plant processed 1,246,301,000 gallons of water. Groundwater is used as the raw water source.

A well field, consisting of six wells, pumps water to the plant for treatment. The McNairy Limestone Geologic Formation is the source of raw water. The existing treatment facility was completed in 1992 as a nominally rated 7 MGD plant, however the current production is about 3.33 MGD. The water system is known for providing very good quality of water: soft, and free of taste and odor.

Loss of Water Service

The City of Murray Water System expressly reserves the right to disconnect, confiscate unauthorized devices, and/or discontinue water service or any other connection with or without notice where the City of Murray Water System discovers, finds or is otherwise made aware of any such installation that poses a threat to the public water supply, public health or public safety.

Water Supply

The City of Murray Water System cannot guarantee a specific water pressure, quantity or an uninterrupted supply of water. The supply will be as free from interruptions as is possible. The supply and pressure in the public water system may be affected by main breaks, scheduled repairs, alterations, additions, fire hydrant usage, variations in hydraulic performance and acts of God.
