The North Texas Municipal Water District (NTMWD) has scheduled a free chlorine maintenance that will be conducted on the NTMWD Wylie water transmission system and customer cities’ distribution systems for a 28-day period beginning Jan. 14, 2013. As a member city, Richardson receives its water from NTMWD.
Free chlorine maintenance allows water suppliers to maintain the disinfectant residual in their systems without flushing systems, 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 Texas Commission on Environmental Quality. Chloramines provide a longer lasting residual disinfection in water pipelines and storage facilities.
The free chlorine maintenance does not affect water quality, and water 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.
