Where Our Water Comes From

The City of Murphy receives drinking water from (NTMWD) North Texas Municipal Water District. Murphy’s water is mainly from Lake Lavon. The NTMWD Water Treatment Plants are in Wylie, Texas. Lavon Lake serves as the NTMWD’s main raw water supply source, with the NTMWD holding water rights in the reservoir. Lavon Lake also serves as a terminal reservoir for additional supplies that are transferred to the reservoir to augment supplies from Lake Texoma, Jim Chapman Lake, Lake Bonham, and the East Fork Wetland Project. Additional supplies are available through a contract with the Sabine River Authority (SRA), providing for water transfer to Lavon Lake from Lake Tawakoni, and from a contract with the Greater Texoma Utility Authority for additional supplies from Lake Texoma. Murphy’s distribution system is supplied by 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 over 6,200 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 Elevated Storage Tanks (EST) with a capacity of 1-million-gallon each supply the northern part of the city. The EST’s are located on West Betsy Lane and Rodeo Drive. The Hawthorne Pump Station houses three Ground Storage Tanks (GST), including a 2-million-gallon, a 1-million-gallon, and a 250,000-gallon GST to supply the southern side of the City. The City’s water pressure average is 65 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 conveyance sanitary sewer system with required capacity by connecting to a 30-inch main line with the Muddy Creek Regional Waste Water Treatment Facility in Wylie, Texas. The City of Murphy does not treat any wastewater collected.
