All residential or commercial structures in Grant County provided with water service and/or a water plumbing system that are intended for permanent or intermittent human habitation or to occupy as an accessory use not connected to public sewer, shall be served by a state-approved private on-site wastewater treatment or holding systems design into which all domestic wastewater and sewage shall enter for holding or treatment and dispersal that complies with the provisions of the Wisconsin Statutes, Wisconsin Administrative Code and this chapter.
A. 
Portable restroom. A portable restroom must be a state-approved product for the use, and the pumping, transportation and disposal of the contents shall be in accordance with Ch. NR 113, Wis. Adm. Code, and shall be maintained pursuant to this chapter. A permit is not required for the placement and use of a portable restroom.
B. 
Vault privy. Only vaulted-type privies are allowed pursuant to this chapter, and require an approved, Grant County vault privy nonplumbing sanitation system permit prior to placement or construction on a parcel. The pumping, transportation and disposal of the contents of a vault privy shall be in accordance with Ch. NR 113, Wis. Adm. Code, and shall be maintained pursuant to this chapter. Pit privies are not permitted in Grant County.
C. 
Nonplumbing sanitation system. Nonplumbing sanitation systems pursuant to Ch. SPS 391, Wis. Adm. Code, are not recognized as an existing POWTS design for a replacement holding tank permit. A permit is not required for the placement or construction of a nonplumbing sanitation system within the scope of Ch. SPS 391, Wis. Adm. Code, except for vault privies and camper unit transfer container use.
D. 
Holding tank. Installation or use of a holding tank in Grant County for a new construction site (new system) or method is prohibited. Holding tanks are allowed as the system of last resort only as a replacement system to an existing failing POWTS. A sanitary permit application that designates a holding tank as a replacement system or as a system failure contingency plan shall not be approved unless a soil and site evaluation report determines that the property is unsuitable for any type of in-situ, soil-based POWTS design.
E. 
Building sewer. If placement of 18 inches of soil cover over the building sewer pipe per § 382.30(11)(c), Wis. Adm. Code, results in less than eight inches of separation between the soil and untreated or unprotected building materials, an approved alternative method of frost protection shall be used.
F. 
Public sewer. When public sewer, becomes available to a property served by a POWTS, connection to the public sewer shall be made within one year from date of availability as established by the local public sewer service entity. The disconnected existing POWTS shall be abandoned per code.
An application from a property owner(s) for any permit governed by this chapter or a soil and site evaluation report submitted to the Grant County Conservation, Sanitation and Zoning Department for review grants consent from the property owner(s) to department staff to enter the owner(s) properties during normal working hours to perform installation, operation, maintenance or soils inspections at the discretion of the Grant County Conservation, Sanitation and Zoning Administrator or Zoning/Sanitation Technician.
A. 
When a POWTS or nonplumbing sanitation system is identified as failing or identified as unlawfully altered or installed, its use shall be discontinued, and an order shall be issued to the responsible person(s) to correct or replace the POWTS or nonplumbing sanitation system.
B. 
When a component of a POWTS or nonplumbing sanitation system is identified as failing to operate or function as designed, the entire system shall be evaluated for compliance to the Wisconsin Administrative Code in effect at the time the system was installed, including a soils evaluation for those components that utilize in-situ soils for treatment or dispersal.
When public sewer connection is required or components of an existing POWTS are not part of an approved replacement POWTS design or when an existing POWTS or components thereof are identified as failing they shall be abandoned as prescribed per § SPS 383.33, Wis. Adm. Code. The contents of all abandoned tanks, seepage pits, or cesspools shall be pumped out and disposed of in accordance with Ch. NR 113.
A. 
The provisions of this article are to establish lots and elevations with sufficient areas and soils to permit the installation and use of soils-based POWTS designs to serve one- and two-family dwellings that shall apply to all proposed subdivision plats not served by public sewer. Proposed standard building lots on subdivision plats shall comply with the lot standards, zoning, and dimensional requirements of all applicable Grant County ordinances.
B. 
Plat submittal. A proposed subdivision plat not served by public sewer shall be submitted to the CS&Z Department for review with all applicable fees and must be accepted and approved prior to final plat approval with the Register of Deeds office. In addition to the requirements of the Grant County Subdivision Ordinance[1] a proposed subdivision plat submitted for review shall be drawn to scale that clearly indicates and includes:
(1) 
All lot areas that do not meet the area, width, elevation, soil, wetlands, floodplain or zoning requirements shall be delineated with limitation(s) identified and restricted by a clearly labeled outlot restriction on the plat. This restriction shall prohibit the construction of buildings and POWTS installations.
(2) 
Identify all lots that will have structures built to be served by a community-type POWTS design and identify all areas where a community-type system will be located.
(3) 
Ground grade elevation contour lines at two-foot intervals for areas of up to ten-percent slope or at five-foot intervals for areas up to twenty-percent slope and at ten-foot interval for areas over twenty-percent slope related to a vertical elevation reference point (benchmark).
(4) 
A soil and site evaluation report conducted by a certified soil tester per § SPS 305.33, Wis. Adm. Code, with profile descriptions and interpretations performed and reported as specified in Ch. SPS 385, Wis. Adm. Code, at a minimum of one soil profile evaluation excavation per each continuous two-acre of plat area, excavated to a depth of at least four feet below an expected POWTS infiltrative surface elevation. The location of all soil profile evaluation excavations and their undisturbed grade elevations related to a vertical elevation reference point (benchmark) shall be delineated on the plat.
(a) 
Additional soil profile evaluation excavations may be ordered as determined to be necessary at the discretion of the Grant County Conservation, Sanitation and Zoning Administrator or Zoning/Sanitation Technician prior to plat approval.
(b) 
The use of existing documentation that may verify soil conditions of all or part of a proposed plat may be allowed with preapproval by the Grant County Conservation, Sanitation and Zoning Administrator or Zoning/Sanitation Technician.

Editor's Note: See Ch. 305, Subdivision of Land.
Soil and site evaluation reports recorded prior to January 1, 1981, or that do not indicate grade elevations for soil borings related to a vertical reference point shall require soils and site verification by a certified soil tester if used as supporting documentation for a sanitary permit or County sanitary permit application. Verification shall require a complete soil and site evaluation report with a minimum of one soil profile evaluation excavation performed within the previously tested area. Additional soil profile evaluation excavations may be required.
Construction of a structure, addition or modification to a structure determined to cause an increase in wastewater flow and/or contaminant load to an existing POWTS serving the structure or property, the owner(s) shall possess a sanitary permit to modify the existing POWTS or to install a replacement POWTS that will accommodate the increase in wastewater flow and/or contaminant loads prior to starting construction or the property owner(s) shall provide documentation to the Grant County CS&Z Department that a POWTS with sufficient soils and size to accommodate the increase in wastewater flow and/or contaminant load already exists to serve the structure. This shall include a plot plan per Article IV, § 225-26C, with the locations of the proposed structure, addition or modification and all existing POWTS components identified to confirm all required setback distances are met.
Prior to starting construction of a structure, an addition to or a structure modification serviced by an existing POWTS, the owner shall provide documentation to the Grant County CS&Z Department that the proposed construction will not cause or affect an increase in wastewater flow and/or contaminant load to the existing POWTS.
Construction of a structure, addition or modification to a structure determined to cause an increase in wastewater flow and/or contaminant load to an existing POWTS servicing the structure or property may be allowed without installing a new, or modifying the existing, POWTS if an alternative method of calculating wastewater flow and/or contaminant load is used. The property owner(s) shall provide documentation of an alternative method of calculating wastewater flow and/or contaminant load based on a per capita occupancy (number of users), or on water meter flow data, or on total facility function flow or on effluent wastewater analytical data if the contaminant load is affected. Forms provided by Grant County Conservation, Sanitation and Zoning Department.
Documents and forms created or revised for the administration of this chapter shall be part and inclusive to this chapter.
Recorded document(s) are created to establish and implement the management and maintenance requirements and responsibilities, ownership and use restrictions for private on-site wastewater treatment or holding systems and, pursuant to this chapter, nonplumbing sanitation systems and use permit components. Such document(s) shall be recorded as an affidavit and restrictive covenant with the Grant County Register of Deeds office (including recording fee) and with the Grant County CS&Z Department in a manner that will permit the existence of the document(s) to be determined by reference to the property. The requirements and responsibilities as prescribed by such document(s) are binding upon the property owner(s), any subsequent owner(s), their heirs, and assignees and shall run with the land. Applicable items to be recorded are but not limited to the following:
A. 
Management and maintenance agreements, installation agreements and limited-use agreements.
B. 
If a POWTS serves more than one structure under different ownership or owned by a party other than the owner of the parcel on which it is installed, a document identifying all parties that have ownership of the parcel, the POWTS, and the structure(s) to be served by the POWTS. All owners are jointly and severally responsible for the operation and maintenance of the POWTS.
C. 
If a POWTS or parts thereof serving a property are located on a different parcel or lot, an appropriate overhead and underground access, inspection, operation and service easement is required.
D. 
If a POWTS design wastewater flow from a dwelling is based on methods other than the number of bedrooms, a document identifying and establishing the method used with occupancy limitation or use restriction to the dwelling determined by an alternate design wastewater flow calculation.
Monetary fees are herein established to defray the cost of administration of this chapter, and shall be required as part of a permit application and for, but not limited to, sanitary document review and inspections. The fees shall be set and amended from time to time by the Grant County Conservation, Sanitation and Zoning Committee.
