Hatcase Pond, located in Dedham and Eddington, has been the primary water source for the City of Brewer, and parts of Eddington, Holden and Orrington, since the 1950’s. Our treatment begins with maintaining a high quality water source. To maintain a high quality water source, we have focused on limiting activity around Hatcase pond through land purchases and conservation easements.
Next, we treat the water at Hayes Treatment Plant using the following treatment techniques to ensure the safety of the water delivered to your system. These techniques include ozonation and chloramination. Ozone gas, a powerful disinfectant, is used to provide primary disinfection. Chloramines, a combination of chlorine and ammonia, are used to provide a disinfectant residual in the distribution system. Ozone levels at the plant and chloramine residuals in the distribution system are continuously monitored to ensure adequate disinfection has occurred, prior to delivery to you.
