The user population of the Horseshoe Bay Water Distribution System does not reach its peak until summer and the resultant levels of peak and low usage vary widely. This fluctuation impacts levels of disinfectant residual and, consequently, water quality — especially at the end of the line. Maintaining proper disinfectant residual is not traditionally problematic for closer lines of the system. Also, manual flushing of the utility’s hydrants to maintain water quality has resulted in excessive time and labor as workers must access the outlying areas.
Horseshoe Bay wanted to make this automated flushing project part of a much more comprehensive program to maintain water quality in our system.
