Clean, reliable drinking water is one of the most important services HCMUD 71 provides. The District operates under strict regulations established by the Texas Commission on Environmental Quality (TCEQ) and the U.S. Environmental Protection Agency (EPA) designed to protect public health and ensure that drinking water meets state and federal safety standards.

HCMUD 71 obtains its drinking water from groundwater wells that draw from the Evangeline Aquifer in Harris County. This water is disinfected with chlorine, as required by state and federal regulations, before it enters the District’s distribution system. Chlorine helps control potentially harmful microorganisms and maintain a disinfectant residual as water moves through the system.

Every stage of the District’s water system is carefully monitored to maintain quality and reliability. TCEQ requires routine testing for a wide range of water quality indicators, including disinfectant levels, pH balance, and the presence of naturally occurring minerals and trace elements. The District also tests for potential contaminants such as bacteria, nitrates, lead, and copper according to federal Safe Drinking Water Act standards. Testing is conducted at multiple points throughout the system, from the source wells to the storage tanks to customer connections, to ensure consistent quality.

Water samples are analyzed by state-approved laboratories, and results are reviewed by TCEQ. If a sample does not meet established limits, the District is required to take immediate corrective action and notify regulators. These safeguards ensure that potential issues are identified and addressed promptly to protect public health.

Each year, residents receive a Consumer Confidence Report, also known as an Annual Drinking Water Quality Report, which summarizes water quality testing results for the previous calendar year. The report provides detailed information on the District’s water sources, detected substances, and compliance with state and federal standards. Copies of the report are made available through the District’s website and provided to customers as required by law.

To further protect the system, HCMUD 71 maintains active disinfection processes at all times using chlorine residuals approved by TCEQ. The District also conducts routineflushing of water lines to remove sediment and maintain water clarity. Storage tanks, wells, and valves are regularly inspected and maintained to ensure proper operation and prevent contamination.

Water quality management also depends on residents. The District’s Rate Order requires backflow prevention devices on sprinkler systems, pools, spas, and other potential cross-connections to prevent non-potable water from entering the District’s system. Residents should report any sudden changes in water clarity, pressure, or odor to the District’s water operator, Regional Water Corporation, at (281) 897-9100.

Residents are also encouraged to sign up for District email and text alerts at www.hcmud71.com/sign-up-for-email-or-text-message-alerts to receive timely notice of water outages and other service advisories.

By maintaining rigorous testing, well-maintained infrastructure, and ongoing coordination with state and federal agencies, HCMUD 71 works to keep its water supply clean, safe, and reliable for all residents.
