This chapter is adopted pursuant to the authorization in §§ 59.70(1), 59.70(5), 145.20, 145.245, 145.13, 145.19, Wis. Stats. and Chs. SPS 382, 383, 384, 385, 386, 387 and 391, Wis. Adm. Code.
(1) 
This chapter is adopted to promote and protect public health and safety by assuring the proper siting, design, installation, inspection and management of POWTS and nonplumbing sanitation systems.
(2) 
In order to achieve these purposes, it is the intent of this chapter to include, but not be limited to, the following methods and strategies:
(a) 
Develop a sanitary permit program that continues to ensure public health, safety and welfare to the residents and visitors of Oneida County.
(b) 
Maintain and improve the inspection and enforcement process for new system installation.
(c) 
Improve the maintenance and tracking program for systems previously installed as well as new systems installed each successive year.
(d) 
Allow municipal ownership of a private sewage system servicing multiple structures on different parcels.
(1) 
Oneida County has over 1,127 lakes and other water bodies within its boundaries. It has a large amount of vacation properties that are used on an intermittent basis.
(2) 
The land area of Oneida County includes 791,347 acres and 68,096 acres of surface water. The soil in Oneida County is predominately sandy or loamy, which has moderate to very rapid permeability, but poor treatment capabilities (Soil Survey, Oneida County, Wisconsin, February 1993).
(3) 
Water supplies in Oneida County are predominately drawn from sand and gravel aquifers, which are replenished from precipitation and drainage. Water seeping from private sewage systems help fill these same aquifers that property owners and visitors use for drinking water supplies (Soil Survey, Oneida County, Wisconsin, February 1993).
(1) 
Should any section, clause, provision or portion of this chapter be adjudged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this chapter shall not be affected thereby.
(2) 
This chapter shall not create a liability on the part of or a cause of action against the County or any employee thereof for any private sewage system or nonplumbing sanitation system which may not function as designed. There shall be no liability or warranty for any site which is approved or denied. The issuance of a sanitary permit and the final inspection of such a system does not warrant the system's function, nor is there a guarantee that the system is free of defects or that all aspects of the system comply to Wisconsin Statute or Administrative Code requirements.
The provisions of this chapter shall be held to be minimum requirements and shall be liberally construed in favor of the County and shall not be deemed a limitation or repeal of any other power granted by the Wisconsin Statutes and related administrative codes.
The following terms shall have the meanings indicated in this section.
