City of Duncanville Water Company

How do we source our municipal water? Duncanville receives its water from surface water sources and has consistently maintained its "Superior" water quality rating. We purchase our surface water from the City of Dallas, which processes and utilizes water from seven distinct sources: the Elm Fork of the Trinity River and lakes Grapevine, Lewisville, Ray Hubbard, Ray Roberts, Tawakoni, and Fork.

The Texas Commission on Environmental Quality (TCEQ) has conducted a Source Water Assessment for all municipal water systems that manage their own sources. This assessment describes how vulnerable your water supply might be to contamination based on environmental conditions and human activities. The system from which we purchase our water has received this assessment report.

According to the water loss audit submitted to the Texas Water Development Board covering January 1 through December 31, 2017, the Duncanville system experienced an estimated 8.59% loss of total system input volume. For additional information about our system, please contact us at (972) 780-4900.

Special Notice: Some individuals may be more susceptible to certain microbial contaminants like Cryptosporidium in municipal water. This includes infants, some elderly persons, and those with compromised immune systems (such as organ transplant recipients, people undergoing chemotherapy or steroid treatments, and individuals with HIV/AIDS or other immune disorders). These individuals should seek guidance from their healthcare providers regarding their water consumption. Additional guidelines for reducing infection risk from Cryptosporidium are available at www.epa.gov/safewater or by calling the Safe Drinking Water Hotline at (800) 426-4791.

This report summarizes the quality of water we provide our customers, using data from the most recent EPA-required tests.

Additional Health Information for Lead: If present, elevated lead levels can cause serious health problems, particularly for pregnant women and young children. Lead in municipal water typically comes from materials and components associated with service lines and home plumbing. While we're responsible for providing high-quality water, we cannot control the materials used in plumbing components. When your water has been sitting for several hours, you can minimize potential lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If concerned about lead in your water, consider having it tested. Information about lead in municipal water, testing methods, and steps to minimize exposure is available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.
