Land requires a means to supply water by means of either an on-site private sub-surface well, or municipal water service. An on-site private well can be location by an on-site inspection or by well drilling records at the local municipality. Private wells are usually governed by the Clean Water Act, and localBoard of Health. A municipal water supply system is governed by the Massachusetts Department of Environmental Protection (MDEP) and the local water department. The location and age of an on-site well is important relative to the specific design requirements and setbacks to structures, property lines, and on-site sub-surface septic disposal systems, and resource areas described in the Massachusetts Wetlands Protection Act (M.G.L. Chapter 131, Section 40). Municipal water will be the responsibility of the local water department where the water extends from the property boundary to the water main. Associated water quality, easements and betterment fees can affect a properties value. Permitting for on-site sub-surface water well can vary depending on the site constraints. The jurisdictional regulatory authority include but are not limited to local Board of Health, and Conservation Commission, A municipal sewer system usually has a local water department or public works department to regulate connection or extension to the water piping network unless operating through the Commonwealth of Massachusetts.
