Deer Park Water Division
The Deer Park Water provides water for about 32,964 residents living in the Deer Park area, Texas. Established in 1893, Deer Park Water collects surface water supply from Trinity River via Lake Livingston. This water is purchased from the City of Houston through the Coastal Water Authority. Besides surface water, the City of Deer Park maintains three wells on standby that could be used on an emergency basis if the raw water supply should be interrupted for any reason. These wells draw water from the Gulf Coast Aquifer.
