The North Texas Municipal Water District (NTMWD) has scheduled a free chlorine maintenance on the NTMWD Wylie water transmission system and customers’ distribution systems from March 7 to April 4.
The free chlorine maintenance does not affect water quality and remains safe for use. During this period, consumers who are sensitive to taste and odor changes in drinking water might notice a change during this period. This palatability change does not alter the quality of the drinking water provided to consumers.
The Texas Commission on Environmental Quality (TCEQ) allows water suppliers to perform free chlorine maintenance. Free chlorine maintenance helps reduce the need for water suppliers to flush systems in order to maintain chloramine residual (required by the TCEQ) during the warm weather periods, thus conserving water.
The NTMWD utilizes chloramines, a combination of chlorine and ammonia, in the water treatment process and to provide the disinfectant residual in the transmission and distribution systems as required by the TCEQ. Chloramines provide a longer lasting residual disinfection in water pipelines and storage facilities.
