Midlothian Water Hardness & Quality Report (2026)

The City of Midlothian, Texas provides water service to approximately 35,000 residents through a municipal system sourcing surface water from three major reservoirs: Richland Chambers Lake, Cedar Creek Lake, and Joe Pool Lake. These water bodies span six counties — Navarro, Freestone, Dallas, Tarrant, Henderson, and Kaufman — providing a diverse supply portfolio. The utility operates treatment facilities to process both surface and groundwater sources and can be reached at (972) 775-6663.

Midlothian's water supply originates from the Trinity River watershed, drawing from reservoirs that collect runoff through areas underlain by Cretaceous and Tertiary geological formations. The region's bedrock consists primarily of limestone and sandstone layers typical of North-Central Texas, which naturally contribute dissolved minerals to the water. This geological setting produces a moderately hard water supply, characteristic of the region's carbonate-rich aquifer systems and surface water interactions with limestone formations.

At the moderately hard level, residents experience typical scale buildup in water heaters, reduced soap efficiency, and mineral deposits on fixtures and appliances. Dishwashers, washing machines, and water heaters require more frequent maintenance and descaling. Many households benefit from point-of-use water softeners or whole-house filtration systems to extend appliance lifespan. The 2024 Consumer Confidence Report confirms compliance with Texas Commission on Environmental Quality (TCEQ) standards. However, independent water quality assessments have identified eight contaminants exceeding health advocacy guidelines — including arsenic, radium, and trihalomethanes. Residents concerned about specific contaminants should request the full annual water quality report or contact the treatment plant directly.
