Water Treatment FacilityWater Treatment Plant 6-2016-1609
The City of Cedar Park Water Treatment Plant is located on Lake Travis and is the source of the City’s drinking water supply. Originally built in 1973, the water treatment plant started with a capacity of 2 million gallons per day (MGD). Since then the plant has undergone several expansions, the most recent of which was completed in 2003, bringing the capacity to 23 MGD. In 2006, the treatment units were re-rated, and approved by TCEQ (Texas Commission on Environmental Quality), for a total capacity of 26 MGD.

Treatment Process:
All of the operations at the City’s treatment facility are regulated by the TCEQ and EPA (Environmental Protection Agency). This facility meets or exceeds all of the requirements of these agencies. The first step in the treatment process is to pump raw water from the lake into the main treatment process; this is where the organic and inorganic material contained in the lake water is removed. This is accomplished through a combination of chemical additions followed by clarifiers to remove the larger particles and mixed media sand filters to remove the smaller particles. There are two types of treatment processes at Cedar Park’s plant; one is a conventional process installed in the 1986 expansion and the other is a high rate modular type treatment process designed to use on the exceptionally clean water coming out of Lake Travis. These modular units also allow quick and cost effective expansions to react to the high growth rates we are experiencing in Cedar Park. The final step in the treatment process is disinfection. The plant feeds free chlorine through the treatment units and is then converted to chloramine before being pumped into the distribution system. The treated water is pumped to large storage tanks at various locations around the service area. The water is distributed from these storage tanks to all our customers.

The plant is staffed 24 hours a day, 365 days a year by professional licensed operators. Their licenses are issued by TCEQ. Nights, weekends and even holidays, the staff is on duty making sure the water is flowing to you. Tests are performed on both the raw water coming into the plant as well as the treated water leaving the plant every day. This testing helps ensure the quality and safety of our drinking water supply. The staff also utilizes a computer based monitoring system called a SCADA (system control and data acquisition) to monitor not only the process taking place within the plant, but also the storage and distribution system.
