Central Acton Water Treatment Plant

 The relative importance of this project is to reduce the concentrations of iron and manganese from the Conant No. 1 and No. 2 sources. The Acton Water District would be unable to meet their projected maximum day demand without these sources, and these sources have been consistently exceeding the SMCL and ORSGL for manganese. The construction of the new water treatment plant will fix the noted problems to ensure public health, safety, and reliability of the water supply.
