Water Treatment Plant


The mission of the Water Treatment Plant is to produce safe and palatable drinking water for the citizens of Midlothian and our wholesale customers.

To achieve this goal, raw water is pumped from Joe Pool Reservoir to the water plant where it is treated to the high standards that have earned a “Superior Water System” rating from the Texas Commission on Environmental Quality. It is then pumped into the distribution system and to the citizens of Midlothian, Rockett, Mountain Peak, Venus, and, occasionally, Sardis and south Grand Prairie. In addition to the 5.95 MGD (million gallons per day) water rights in Joe Pool Lake, Midlothian also has an additional 9 MGD available from the Tarrant Regional Water District. Water from TRWD is treated at Water Treatment Plant No. 2, which began serving the community in the summer of 2013.
