Water Treatment Process
The first step in the treatment process
is the pumping of raw water from Lake Travis into the main treatment plant. The water is then pumped through
state of the art microfiltration membranes which filter out dirt particles, bacteria and even some viruses. The
finished water is exceptionally clean and sent to clearwells for storage. The stored water is treated with
chlorine and ammonia, in a process called chloramination, to kill any remaining harmful organisms. A small
amount of fluoride is also added to prevent tooth decay.
The treated water is pumped to storage tanks at various locations around the service area.
The water is distributed from storage tanks to all our customers. The plant is staffed with professional
operators, licensed by TCEQ. Nights, weekends, and holidays, an on call staff is on duty making sure water is
flowing to you. Tests are preformed on both the raw water coming into the plant as well as treated water
leaving the plant. This testing helps ensure safety of our drinking water supply. The staff also utilizes
a computer based monitoring system called system control and data acquisition (SCADA) to monitor not only
the process taking place within the plant, but also the storage and distribution system.
