All septic systems which exist at the time of adoption of this chapter and which are within one hundred twenty-five (125) feet of any Great Pond in Conway shall be tested by a licensed septic designer on or before December 31, 1992. The inspector shall use a standard inspection form provided by the town and shall report the findings to both the owner and the Selectmen or their appointee. Based on the inspection, the following actions are required where appropriate:

  • If the bottom of the bed or the distribution box is found to be more than two (2) but less than four (4) feet above the estimated seasonal high-water table (ESHWT) and the bed or tank are located between seventy-five (75) feet and one hundred twenty-five (125) feet from a Great Pond, a new system shall be designed and approved by the state within two (2) years from the date of inspection. The existing system may continue to be used but must be inspected by the Selectmen or their appointee annually. The owner shall install a means of inspection accessible at the ground surface, and the owner shall reimburse the town for the cost of each annual inspection. The system shall be replaced immediately upon failure. If the new system is located within one hundred twenty-five (125) feet of the Great Pond, the new system shall have a means of inspection accessible at the ground surface, and shall be inspected by the Selectmen or their appointee at least once every five years.
  • If the bottom of the bed or distribution box is found to be less than two (2) feet above the ESHWT and/or is less than seventy-five (75) feet from a Great Pond, a new system, with a design approved by the state, shall be designed and installed within two (2) years from the date of inspection. If the new system is located within one hundred twenty-five (125) feet of the Great Pond, the new system shall have a means of inspection accessible at the ground surface, and shall be inspected by the Selectmen or their appointee at least once every five years.
  • If the bottom of the bed or distribution box is found to be in the ESHWT and/or is found to be in failure, a new system, with a design approved by the state, shall be installed immediately. If the new system is located within one hundred twenty-five (125) feet of the Great Pond, the new system shall have a means of inspection accessible at the ground surface, and shall be inspected by the Selectmen or their appointee at least once every five (5) years.

In the event that an existing lot is developed or redeveloped, or an existing system is being replaced, and there is no possibility of meeting the setbacks listed in 122-2 and 122-3 above, a septic system shall be allowed at the sole discretion of the state. New lots shall be created only if the standards listed in 122-2 and 122-3 above can be met.
