The City of Midlothian’s water treatment facilities produce treated raw water for both retail users (residents, businesses, industries, etc.) and wholesale customers. The city’s two water treatment plants currently have a combined rated capacity of up to 24 million gallons per day (MGD).

The city’s Tayman plant (plant No. 1) is a conventional water treatment plant that was initially built to treat up to 3 MGD in the mid-1980s. Over the years, this plant has undergone a number of expansions and upgrades and currently has a rated treatment capacity of up to 12 MGD. The raw water source for this plant is Joe Pool Lake, which the city has under contract with the Trinity River Authority of Texas. 

The city’s Auger plant (plant No. 2) is a low-pressure microfiltration membrane water treatment plant that was initially built with a rated capacity of 8 MGD in 2013.  This plant, which was expanded to 12 MGD in 2022, is once again under construction to expand to a rated treatment capacity of 24 MGD by the spring of 2024. Raw water sources for this plant are Richland Chambers and Cedar Creek lakes, which the city has under contract with the Tarrant Regional Water District. 

Our goal has been and always will be to provide the safest quality water to the citizens of Midlothian and our wholesale customers. Our management team and operation and maintenance staff take pride in providing this service to our community. The city has been recognized as a Superior water system by the State of Texas.
