Water Plant Operations
The City of Horseshoe Bay began providing water to Horseshoe Bay in 1973.
The City operates two Water Treatment Plants, Central
and West. Under a purchasing contract with the Lower Colorado River Authority the City obtains untreated lake water from Lake LBJ. According to the annual Consumer Confidence Water Quality Report (PDF), the plants consistently produce water meeting or exceeding both state and federal standards. All City plant operations personnel responsible for production of treated water participate in advanced training and licensing to ensure that the water quality and plant operations remain at their best.
Water Treatment Plants
The Central Water Treatment Plant, completed in May 2006 is capable of producing 4.0 million gallon of water a day (MGD). The facility combines conventional coagulation and settling with a state-of-the-art filtration system. PALL Water Processing supplied the new filtration equipment described as "Microza Membrane Technology". The PALL filtration system was developed to provide a 5 Log (99.99%) reduction of Cryptospordium and Giardia lamblia cysts with a 0.1-micron (0.0000039") membrane filter. Along with new treatment equipment installed a the Central Water Treatment, a SCADA System, (Supervisory Central and Data Acquisition System) including fire and security systems have been installed to monitor and control the water production process.
June 2017 the City upgraded the West Water Treatment Plant from 1 million to 2 million gallons a day, equipped with the same type of Micro Filtration system as the Central Water Treatment Plant.
The City's central water storage system consists of two tanks on Pawnee with a combined 3.0 million gallons. Water is pumped to the City's 750,000gallon Elevated Water Storage tower built in 2014, located in Summit Rock Subdivision. Centrals distribution system is capable of transferring water from Summit to the West Elevated Tower via an interconnect between the two distribution systems. The West Water Storage system consists of one elevated storage tank located near the West Fire Station on Broken Hills.
Water produced at the Water Treatment Plants is treated with:
- a combination of Chlorine and Ammonia are added as a disinfectant in accordance with state and federal regulations
- acid and caustic for pH adjustments to achieve maximum total organic carbon (TOC) removal prior to disinfection which was designed to lower disinfection by-products to greater levels than mandated by state and federal regulatory agencies
- Aluminum sulfate (alum) and polymer for coagulation
The Utility Department provides water to City customers in Bay Country, Escondido, Horseshoe Bay, Horseshoe Bay South, Horseshoe Bay West, Pecan Creek, Sienna Creek,The Trails of LBJ. The City also furnishes treated water to Oakridge, Deerhaven and Sandy Harbor Subdivisions under wholesale contracts and provides out of City services to The Hills and Quail Ridge Subdivisions.
Water Plant Projects
Due to the drought that occurred in 1999, the West Water Treatment Plant construction was expedited and was online in September 2001. This plant is a modular treatment facility with a capacity of 1 million gallons per day. The site was designed to accommodate another 1 million gallon treatment unit within the existing building. The total cost of the facility was $2.2 million. Construction to expand capacity to 2 million gallons per day was completed in 2018.
