Where Our Water Comes From

The City of Murphy purchases water from the (NTMWD) North Texas Municipal Water District, located in Wylie, Texas. With two large capacity supply lines passing through the city, sufficient water for the foreseeable future is assured.

About Our Water Supply

The City of Murphy supplies water to approximately 5,700 households and businesses. The City has generator backup power supplies to ensure that water and wastewater services will have power available even through extended power outages.  Two water towers with a capacity of 1-million-gallon each supply the northern part of the city. Towers are located on West Betsy Lane and Rodeo Drive.  The Hawthorne Pump Station houses three ground water storage tanks, including a 2-million-gallon ground storage tank, a 1-million-gallon ground storage tank, and a 250,000-gallon ground storage tank to supply the southern side of the City. The City’s water pressure is about 60 to 70 PSI.

Water Odor & Taste

Spring and fall sometimes bring a change of odor and flavor to the public water supply since our water source includes surface lake water from Lavon Lake. This is not a health hazard.  The NTMWD is upgrading the plant to include ozone to treat the water which will improve the seasonal taste and odor issues.

Wastewater Infrastructure

The City has a complete sewer system with required capacity by connecting to a 30-inch line with the Muddy Creek Regional Waste Water Treatment Facility in Wylie, Texas.
