The Boone County Regional Sewer District also serves parts of unincorporated Boone County (BCRSD).

Septic Pumping in Columbia
Columbia's sewer service covers the city. Septic tanks are on the edges, in older subdivisions and rural acreage beyond the city limits, where heavy clay and perched water tables are common. Hinkson Creek, the city's largest watershed, runs southwest through town and joins Perche Creek in southwest Columbia (City of Columbia watersheds page).
Septic Pumping in Ashland
About 10 miles south of Columbia. The City of Ashland owns its sewer system, and BCRSD has provided contract operations since 2022. Rural homes outside the city's lines use septic tanks or lagoons. See our Ashland septic pumping page for the city's system, county lagoon rules and local soils.
Septic Pumping in Hallsville
About 13 miles north of Columbia. Missouri American Water owns the town's sewer system. Farms and acreage around it rely on septic tanks and lagoons. See our Hallsville septic pumping page for details on the claypan soils and the head of Hinkson Creek.

Septic Pumping in Rural Boone County
Most of Boone County outside its towns is on septic tanks or lagoons. A few county-level facts shape how those systems work.
Who's in charge. Boone County Resource Management administers the county's onsite wastewater ordinance, first adopted in 1993, and took over enforcement on June 28, 2022. The Boone County Regional Sewer District, formed in 1973, provides public sewer in parts of unincorporated Boone County. It contract-operates the City of Ashland's plant. Where neither a city nor the district has a line nearby, the property is on its own system.
Lagoons. Single-family lagoons are common on larger rural parcels. Under the county's lagoon requirements (updated 2022), they're not generally suitable in subdivisions with lots under 3 acres, they need 500 feet from any sinkhole, and they need at least 3 feet between the bottom and creviced bedrock. Designated sinkhole areas require an engineer-designed, certified system.
Soils. By mapped acreage in USDA NRCS soil survey data, Boone County's three most extensive soil series are Keswick, Mexico and Leonard. The official series description for Mexico places it in the Central Claypan Till Plains: very deep, poorly drained, with a dense clay subsoil. Leonard is also poorly drained and slowly permeable, and Keswick is somewhat poorly drained. All three are rated "very limited" by NRCS for septic absorption fields because of perched water and slow water movement. That's the claypan problem in a sentence: water sits on the clay rather than soaking through.
Karst. Not all of the county is claypan. On the stony slopes around Ashland, soils such as Bardley and Clinkenbeard sit over dolomite, with bedrock as shallow as about 2 to 3 feet. The county's lagoon rules treat sinkhole areas separately, and state rules keep tanks 50 feet and absorption areas 100 feet from a sinkhole's edge.

Who Regulates Septic Here
- Boone County: Boone County Resource Management has enforced the county's onsite wastewater ordinance since June 28, 2022. Its page lists a $510 permit fee for a new system or an upgrade, and a $35 "existing evaluation" fee. That evaluation is required when you add bedrooms or bathrooms to a home on septic. It isn't a home-sale inspection.
- Lagoons: single-family lagoons are under the county. Lagoons serving more than a single-family home fall under the Missouri Department of Natural Resources, per DHSS.
- Statewide: the Missouri Department of Health and Senior Services onsite program sets the construction standards in 19 CSR 20-3.060. Real-estate inspections fall under 19 CSR 20-3.070.
