The interim system has been sized to treat the maximum amount of water (1 million gallons per day [MGD]) that the Morses Pond wells can pump given the additional hydraulic constraints imposed by the additional treatment equipment. The interim treatment media (GAC/IX) are estimated to last more than 16 months based on current PFAS levels and proposed system flow rate (1 MGD). The current cost to purchase water from the MWRA is $4,000 per 1 million gallons. There is both a cost savings component and a demand component of the interim solution that will benefit the Town. There are times during peak demand that the MWRA system will be at maximum pumping capacity and we will still need the additional million gallon supply to meet the system demand.
