Permits

Who issues them here.

Permit fees, forms & process

Any new system or major repair in Howell County needs a permit before construction starts. This county’s full guide is still in production — the authority contact is the official source in the meantime.

All Missouri permit guides

Local rules

What’s different in Howell County.

Four things decide what you can build and what it costs: zoning, environmental protections, power for aerobic systems, and the ground itself. We publish each one only where we have checked it — and say so plainly where the answer is “same as the rest of Missouri”.

Zoning & land use

No Howell County ordinance governs onsite wastewater here. The state standard in 19 CSR 20-3.060 applies, and DHSS contracts Howell County Health Department to take the construction permit application and inspect the work. RSMo 701.031 exempts a single-family lot of three acres or more from state permitting, with conditions - confirm the exemption with that office before anyone digs.

Source: Missouri Department of Health and Senior Services, OWTS Construction Permit Process - the department's own per-county permitting-authority list, giving the agency, authority type (DHSS Onsite Program, Local Authority by contract, or Local Authority via ordinance), address and phone for each Missouri jurisdiction ↗ · retrieved Sep 1, 2026

Also: Missouri Revised Statutes section 701.040(1) - city or county governments may adopt the state standard by order or ordinance, and where none has, the department of health and senior services enforces it - read with section 701.047, which permits a city or county to adopt standards more restrictive than the state's ↗ · retrieved Sep 1, 2026

Environmental protections

Nothing in Howell County changes this. Missouri’s protected-water designations do not change what a household septic system may do. Outstanding National and State Resource Waters, the metropolitan no-discharge streams, the losing streams and Lake Taneycomo are all defined in the Clean Water Commission’s water quality standards (10 CSR 20-7.031), and every one of them attaches to a permitted discharge or a department approval — which an absorption field serving a single home under 3,000 gallons a day is not. The rule that does bind is statewide and keyed to a physical feature rather than to a water body: an absorption field sits at least 100 feet, and a sewage tank at least 50 feet, from the topographic drainage of a sinkhole (19 CSR 20-3.060). Where that matters in a given county is in its geology notes, because that is where the sinkhole measurement is.

How Missouri permitting works

Checked against Missouri Clean Water Commission, 10 CSR 20-7.031 Water Quality Standards, sections (8) Outstanding National Resource Waters, (9) Outstanding State Resources Waters, (10) Lake Taneycomo and (13) Losing Streams, with Tables D, E and F, as published by the Missouri Secretary of State (Code of State Regulations, 9/30/23) ↗ · retrieved Sep 1, 2026

Also: Missouri Department of Health and Senior Services, 19 CSR 20-3.060 Minimum Construction Standards for On-Site Sewage Disposal Systems, definition 54 (setbacks of 100 feet for a disposal field and 50 feet for a sewage tank from the topographic drainage of a sinkhole) and definition 55 (sinkhole) ↗ · retrieved Sep 1, 2026

Geology & soil

Subsoil that percolates too slowly is the governing constraint in Howell County, on 65.7% of the soils Missouri's own NRCS septic suitability rule rates, with a seasonal high water table next at 36.4%. The rule puts 53.7% of the county in its unsuitable class for a conventional absorption field. The Missouri Geological Survey maps 1390 sinkholes here, and 62.9% of the rated soils weathered in place from limestone or dolomite. Effluent reaching solution-widened rock gets little filtering, and 19 CSR 20-3.060 keeps an absorption field 100 feet, and a sewage tank 50 feet, from the topographic drainage of a sinkhole.
