DPW-Water and Sewer


On July 1, 2016 the City of Somerville Water & Sewer Department instituted a monthly water connection charge. This amount will be factored based upon meter size as shown in the following price sheet, for example, an account with a 5/8" meter will be billed $5.00/per month or $20.00/based on a four month, tri-annual billing cycle. Commercial accounts will continue to bill bi-monthly, thus the appropriate base charge will be applied twice a billing cycle.
