Wisconsin State Regulations

Wisconsin Administrative Code
Chapter Comm83, Private Sewage Systems
July 1, 2000

A major Code revision was implemented on July 1, 2000; however, a Code "fix-up" package is in progress, including corrections to Code text, changes in soil application rates, and vertical soil separation distances. The exact effective date is unknown but is estimated at late 2002.

Those technologies approved for onsite wastewater treatment and disposal include gravity/flow, septic tank/soil absorption, pressure distribution, mound, at-grade, holding tank, intermittent sand filter, recirculating sand filter, aerobic treatment unit, dripline, evapotranspiration bed, constructed wetland, peat filter, and fabric filter. Technologies not listed above may be allowed with alternate product approval or experimental approval.

Surface discharge may be permitted by the DNR for large systems (greater than 12,000 gpd). The DNR has jurisdiction over surface discharge systems and issues any required WPDES or NPDES permits.

State Code allows for drainfield area/size reductions. Reduction may be based on treatment efficiency and/or soil application rates.

A funding program exists to assist homeowners replacing failing systems. Questions may be directed to:

Wisconsin State Code requires management programs/contracts or districts to monitor and maintain onsite systems or individual liquid waste systems. All onsite systems approved after July 1, 2000, must include a management plan that lists maintenance requirements. Maintenance contracts are required if service, inspection, or maintenance is required more than once a year by the system designer or component manufacturer. Governmental units must adopt a maintenance program if they participate in the Wisconsin Fund Grant Program. Also, since July 1, 2000, all counties must track inspection, servicing, and maintenance events that are specified in an approved management plan. Counties are just beginning to implement this part of the program.

Approximately 12,000 new construction permits are issued in Wisconsin annually, with approximately 8,000 system repair/replacement permits (combined) issued. These records are maintained at both the state and local levels.

In Wisconsin, a failed system is defined in Ch. 1435.245 Wisconsin statutes that reads, in part: "A failing private sewage system is one that causes or results in any of the following conditions:
a) The discharge of sewage into surface water or groundwater;
b) The introduction of sewage into zones of saturation that adversely affects the operation of a private sewage system;
c) The discharge of sewage to a drain tile or into zones of bedrock;
d) The discharge of sewage to the ground surface;
e) The failure to accept sewage discharges and backup of sewage into the structure served by the private sewage system."
The most common reason for system failure in the state (based on Wisconsin Fund applications) is that the system is located too close or into zones of saturation. These are typically older systems that were installed before proper soil evaluation techniques were in place.

Wisconsin has a licensing/certification program for onsite wastewater professionals. A list of individuals registered, certified, or licensed by the Department of Commerce can be accessed via the Web site http://www.commerce.state.wi.us/SB/SB-CredentialStatusCheck.html Soil/site evaluations are provided by certified soil testers (private); construction inspections are performed by Certified POWTS Inspectors (public), and soil/site and construction inspections/verifications are performed by county and State staff with the same credentials cited above.

Total number of onsite systems: Approximately 680,000 (30% of households); 1990 U.S.
census reports approximately 580,000 systems.

Number of new systems installed each year: Approximately 10,000.

Failure definition: Discharge of “sewage” into the building, surface- or groundwater, draintile
or zones of bedrock, or onto the ground.

Number or proportion of systems presently failing: NA

Number or proportion repaired annually: NA

Number or proportion replaced annually: Approximately 9000.

Number or proportion of repairs or replacements that require alternative technology (e.g.,
sand filters, pressure dosing):
Approximately 2500 per year: 1800 mounds,
400 Wisconsin-at-grades, 300 in-ground pressure systems.

Number or proportion of repairs or replacements that require advanced technology (e.g.,
disinfection, nutrient removal):
Less than 100; about 75 aerobic units and 25 sand filters.

Cost of a conventional septic system installation: $3000-$4000; range $1500-$15,000.

Cost of a centralized sewer tie-in (including fees and cost of the sewer lateral):
$12,000-$30,000.
