15.07.060 Community or cluster systems.
Individual lots or structures to be served by a community system of collection and disposal of sewage by soil dispersal cells shall be clearly marked on the final plat to indicate this means of wastewater dispersal.
(1) Municipal Confirmation. If the components of the proposed community system are not installed and available to all lots or building sites when a final plat or certified survey map is submitted to the County for review, the submitter must include a certified resolution from the city, village, town or town sanitary district that documents and confirms acceptance of the community system and that all buildings within the development will be served by the system.
(2) Ownership. All components of the community or cluster system will be owned and maintained by the municipality and the special purpose district.
(3) Component Accessibility. All components of a cluster system shall be accessible to the municipal employees, their maintenance agents and the County Sanitarian via recorded affidavits, easements, public right-of-ways or municipal land ownership.
(4) Maintenance. The municipality and the special purpose district will have full responsibility for operation and maintenance of the cluster system. They shall be responsible for all maintenance requirements as stated in the conditional approval of the system design plans, as well as requirements stated in any maintenance contracts with a component manufacturer and the County. In addition, they will be required to follow all the requirements stated in the management plan for the system.
(5) Occupancy. With the exception of a model dwelling unit(s), no building shall be occupied unless the cluster system is fully operational and the building is connected to the system.
(6) State Approval. All cluster systems shall be approved by the Department of Commerce and the Department of Natural Resources where applicable. Approval shall be obtained prior to any final plat and/or committee approval by the County Board of Supervisors.
(7) Design Requirements. All cluster systems shall be designed in accordance with Comm. 83 and any other applicable Wisconsin Administrative Codes. All residential designs shall be based on design calculated flows of one hundred fifty (150) gallons per day per bedroom or appropriate public sizing.
(a) The final plat or conditions of the development shall require a recorded maximum design flow for each lot or unit based on 150 gallons per day per bedroom.
(b) Any commercial buildings served by a cluster system shall have a maximum pre-determined design calculated flow. This maximum flow must be recorded information on the final plat or final approved plan.
(c) Contaminant Loads. All cluster systems must maintain influent quality as stated in Comm. 83.44 Wisconsin Administrative Code. In the event commercial or other uses cause the influent quality to be unacceptable, pre-treatment may be necessary to improve the influent quality.
(8) Deviation of Design Plans, Wastewater Flows or Contaminant Loads. All community systems shall be constructed in accordance of the approved plan, not to exceed maximum design flows, maintain acceptable contaminant loads and adhere to all maintenance and monitoring requirements. Any deviation from these requirements will require re-submittal to the Department of Commerce and possible alterations to be done on the system. Deviation from the specifications and limitations relative to the installation and maintenance of the method or technology of a community system will constitute a violation of this ordinance.
