Answers from the rulebook for Ellington

Rules another office applies inside Ellington

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

  • Septic permitLimited

    Onsite wastewater treatment systems inside Ellington city limits when an onsite system is proposed.

    • A construction permit is required before installing or repairing most OWTS.
    • Some single-family residential lots may be exempt from permitting.
    • The permitting agency must be determined for the location; Ellington-specific administration was not identified.
    • Lagoons serving anything other than a single-family residence are under DNR jurisdiction.
    “A construction permit is required before installing or repairing most onsite wastewater treatment systems (OWTS). Some single family residential lots may be exempt from permitting. The first step of the permitting process is to determine the agency that has permitting authority where the work is being done.”
  • Off-grid sanitationLimited

    Onsite sanitation inside Ellington city limits where public sewer is unavailable.

    • OWTS are used where central sewer service is not available.
    • A permit is generally required before construction or repair, subject to residential exemptions and the applicable permitting authority.
    • Local ordinance requirements may be more restrictive than state standards.
    “Generally, a permit must be obtained before starting construction or repair work. However, certain residential properties may be exempt from state permitting requirements. When authority is based on a local ordinance, regulation can be more restrictive than the state standard; check with your local authority.”
  • Well permitLimited

    Water-well construction inside Ellington city limits, Missouri.

    • A driller or pump installer charging for services must have a permit.
    • A landowner drilling the owner's own well or installing the owner's own pump is exempt from permit requirements but must comply with other rules.
    • Public water wells require construction authorization before drilling.
    “Well drillers and pump installers who charge for their services must have a permit to construct a well. Issuing permits to well drillers and pump installers establishes a minimum standard of competency and enables the department to enforce minimum construction standards. Landowners who drill their own well and/or install their own pump are exempt from permit requirements, but must adhere to all other sections of the rules.”

Unanswered questions are usually a sign that Ellington publishes no rule on the point, not that none exists. Reynolds County’s page lists the county offices to call.
