Answers from the rulebook for Westphalia

Rules another office applies inside Westphalia

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

  • Who permits septicCounty (with conditions)

    On-site septic (private wastewater) systems on land inside Westphalia city, Shelby County, Iowa. The county environmental health office's program page covers all on-site systems in Shelby County; it does not name Westphalia city, so this is inferred from the county-wide service area.

    • Iowa DNR states that local boards of health have primary responsibility for systems serving 4 homes or fewer or fewer than 15 people, and that the DNR has primary responsibility for larger public systems.
    • Counties must comply with minimum state standards developed by the Iowa DNR.
    • Westphalia city's own code was not located, so no city sewer or septic rule was found.
