CHAPTER 136 – SANITARY DISTRICT NO. 2 ARTICLE IX – SANITARY SEWER SYSTEM REGULATIONS A136-33 Purpose and Intent of this Article a. The purpose of this chapter is to promote and protect the public health, safety and general welfare of the residents of the Town, to enhance aquatic life, scenic and ecological values and enhance municipal, industrial and recreational use of water. b. The Sanitary District hereby adopts and incorporates herein the NEW Water (formerly Green Bay Metropolitan Sewerage District) Sewer Use Ordinance, dated October 20, 2016, and may be amended from time to time. In case of a direct conflict between this chapter and the NEW Water sewer use ordinance, the terms and conditions of the NEW Water sewer use ordinance shall prevail. c. The objectives of this chapter are to: 1. Prevent the introduction of pollutants into the Sanitary District wastewater system which will interfere with the normal operations of the system; 2. Prevent the introduction of pollutants into the wastewater system which do not receive adequate treatment at NEW Water, and which will pass through the system into receiving waters or the atmosphere or otherwise be incompatible with the system. d. Pursuant to Wis. Stats. 66.0813(3) the Town of Ledgeview Sanitary District #2 limits its wastewater treatment service area as shown on Attachment 1, Ledgeview Sanitary District Boundary and Sewer Service Area Map. This section does not limit the obligation to serve as it existed as of the effective date of this chapter. This section may be amended to expand such service area as provided in Wis. Stats. 66.0813(3).
