Answers from the rulebook for Town of Sand Lake

Rules another office applies inside Town of Sand Lake

Town of Sand Lake does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Septic permitRequired

    New private on-site wastewater treatment (septic) system installed on land inside Sand Lake town, Sawyer County, WI. This is the Wisconsin statute that applies there; the statute does not name the local unit that issues the permit.

    • The permit must be issued by the governmental unit responsible for regulating private on-site wastewater treatment systems. This excerpt does not identify whether that unit is Sawyer County or a town sanitary district; that is unresolved.
    • Approval is based on the regulations in force on the date of approval (s. 145.19(3m)(b)).
    • The permit is valid for 2 years from issue and renewable (s. 145.19(7)); changed regulations do not impair its validity.
    • Permit may be transferred to a subsequent owner of the land, who must obtain a new copy from the issuing agent (s. 145.19(8)).
    • Soil or percolation test results are retained by the governmental unit where the property is located and are accepted as the basis for an application unless the soil at the test site has been altered (s. 145.19(1r)).

    sanitary permit validity period: 2 years

    “no person may purchase or install a private on-site wastewater treatment system unless the owner of the property on which the private on-site wastewater treatment system is to be installed holds a valid sanitary permit issued under this section.”
  • Septic inspectionRequired

    Private on-site wastewater treatment (septic) systems installed on land inside Sand Lake town, Sawyer County, WI, under the statewide statute. The statute does not name the inspecting unit for Sand Lake town.

    • The governmental unit responsible for regulating private on-site systems must inspect after construction and before backfilling (s. 145.20(2)(d)).
    • The statute provides that the unit is not required to conduct an on-site inspection in a listed case: 'is not required to conduct an on-site inspection if a building or structure is being constructed which does not require connection to an existing private on-site wastewater treatment system.' This sentence appears immediately before s. 145.20(2)(i); its lead-in clause was not captured in the page output, so its subsection letter is not confirmed.
    “inspect all private on-site wastewater treatment systems after construction but before backfilling no later than the end of the next workday, excluding saturdays, sundays and holidays, after receiving notice from the plumber in charge.”
  • Permit feesVariable (with conditions)
