The City of Boerne’s water system has been recognized by the Texas Commission on Environmental Quality (TCEQ) as a superior public water system.

Water Treatment and Distribution

The City obtains its drinking water from surface and ground water. The City owns and operates the Surface Water Treatment Plant at Boerne City Lake and nine groundwater wells. Additionally, the City purchases treated surface water from Canyon Lake through the Guadalupe-Blanco River Authority.

Boerne Utilities is permitted to withdraw 833-acre feet (271.4 million gallons) of water each year from the City Lake. The City has a ground potable water storage tank capacity of 4 million gallons and operates three pressurizing standpipe tanks.

Additionally, the City provides reclaimed water for landscape irrigation from the Wastewater Treatment and Recycling Center. Currently, the City has one ground and one elevated storage tank for reclaimed water.

The City’s water distribution systems provide water to customers within the city limits and WCID #3 (Esperanza). The City owns and maintains the portion of each customer’s water service line that runs from the water main distribution network to the customer meters typically located near the customer’s front property line.

Wastewater Treatment and Collection

The City is permitted by the Texas Commission on Environmental Quality (TCEQ) to discharge 1.2 million gallons per day from the Wastewater Treatment Plant located on Esser Road. The plant discharges to Currey Creek, which flows into the Cibolo Creek south of Highway 46.

Additionally, the City is permitted to discharge 1.4 million gallons per day from the Wastewater Treatment and Recycling Center (WWTRC) located on Old San Antonio Road. The WWTRC discharges to Menger Creek, which also flows into the Cibolo Creek south of State Highway 46. It also serves as the supply for the City’s reclaimed water distribution system.

The City’s wastewater collection system provides service for customers within the city limits of Boerne and WCID #3 (Esperanza). The City owns and maintains the portion of each customer’s sewer service line that extends from the sewer collection system main to the customer’s point of connection, typically a clean-out located near the customer’s front property line.
