Plano's Water Source


The City of Plano contracts with the North Texas Municipal Water District (NTMWD) for the water supply to our community. Since its founding in 1951 by ten cities, including Plano, the primary concern and responsibility of the NTMWD has been the conservation and preservation of clean, high-quality, safe drinking water. This concern is shared by the City of Plano, who with the NTMWD has combined proper operation and up-to-date technology to provide consistently safe, reliable and quality drinking water to Plano water consumers.

The NTMWD obtains surface water from three sources: Lake Lavon, Plano’s primary water source, and Lakes Texoma and Cooper, our supplemental water sources. TNRCC will be reviewing all of Texas’ drinking water sources. The source water assessment process will be completed within three years. It is important to protect your drinking water by protecting your water source.
