Highland Village's self-supplied ground water is treated with chloramines, a type of disinfection where ammonia is injected into the raw water prior to chlorine.
City water technicians obtain daily chloramine residual samples to assure proper water disinfection levels are obtained and maintained. Water samples are also submitted to a laboratory for bacteriological analysis on a monthly basis.
In compliance with Texas Commission on Environmental Quality (TCEQ) and U.S. Environmental Protection Agency requirements, the City of Highland Village produces and mails out to citizens an annual water quality report. The annual Consumer Confidence Report provides information regarding the contents of Highland Village's water. View the most recent or all past Consumer Confidence Reports.
