Wastewater Services

The City of Horseshoe Bay treats its customer's wastewater at a treatment plant located west of Horseshoe Bay. The treatment plant is a Sequence Batch Reactor plant built by Aqua Aerobics.

About the Sewer System


The low-pressure sewer system installed by the City was the first to be installed in Texas and is now a popular option for many areas where rock or groundwater problems exist. After the customers utilize the potable water, it is then collected from the resident's home or business into a grinder pump system basin located on the customer's property. The pump is usually within 10 feet of the building.

The grinder pump system basin collects the wastewater which is ground up and pumped by a pressure pump through the customer's yard line to the City's sewer mainline. The main lines transport the wastewater to large collection basins called lift stations. The lift stations collect wastewater from a large geographical area usually defined by the topographical nature of the collection area. The wastewater is then pressurized and pumped through large mainlines called trunk lines that transport the wastewater to the treatment plant to be treated. 

As of October 2018, the City of Horseshoe Bay maintains 3,606 individual grinder pump systems, 88 miles of wastewater mainlines, and 9 wastewater lift stations in the wastewater collection system.
