Certificate of Water Availability: For single-family or two-party water system For public water system |
In order to obtain a septic system permit or building permit, applicants must prove they have source of water. This is accomplished by supplying a "Certificate of Water Availability Form." If the source of water is a single-family, two-family, or Group B water system, the applicant is required to submit a well report fact sheet that describes the well's capacity and construction. This is to ensure that the well meets safety codes and is capable of delivering the necessary volume of water. See column to the right. | Locating or Recreating a Water Well Report Fact Sheet |
