The city of Sugar Land’s Main water system uses chloramines for disinfection. Chloramines are a better long-term choice for systems on surface water because they produce lower levels of disinfectant byproducts like trihalomethanes when chlorine mixes with natural organic substances in water. However, prolonged use of chloramine coupled with other factors that can affect water quality, such as high temperatures, may result in the growth and/or persistence of organic matter within the pipes of the distribution system. Though harmless when consumed by humans, this organic matter can introduce unwanted taste and odor, and hinder the ability to maintain an adequate disinfectant residual. A temporary conversion to free chlorine, partnered with flushing activities, clears distribution pipes of this organic matter and improves the quality of your water overall.
