On October 2, 2017, at 6:00 a.m. East Rio Hondo Water Supply Corporation (PWS ID 0310096) and Arroyo City (PWS ID 0310031) will change our primary disinfectant from "Chloramines" to "Free Chlorine". The change in disinfectant is conducted as an annual distribution maintenance procedure in order to reduce nitrification and biofilm issues throughout our distribution system. It will take time after the change in disinfectants for the conversion to take place in the distribution system. We will be using free chlorine for 4 weeks. The 4-week period will end on October 31, 2017 at 6:00 a.m. After that time period ERHWSC will revert back to Chloramines for our disinfection process. During this conversion process a stronger chlorine/bleach odor may be apparent in your drinking water, as these odors are a product of the breakdown of chloramine by free chlorine. All regulatory requirements will be adhered to during this process in regards to the level of chlorine in your drinking water. E.R.H.W.S.C. advises any customers with medical conditions affected by Free Chlorination to consult medical professionals in regards to any affects concerning consuming chlorinated drinking water. If you have any questions, please contact Amanda M. Ramos, Administrative Services Manager at (956)247-7817.
