(A) General:
1. No subdivision may be approved without sewage disposal facilities that comply with this section, or the posting of surety bonds guaranteeing such improvements.
2. All sewage disposal facilities must be designed and constructed according to all applicable rules, regulations and standards contained in ordinances of the city of Spring Valley, the Illinois environmental protection agency, the "Standard Specifications For Water And Sewer Main Construction In Illinois", and all other applicable agencies. Plans, specifications, and construction must be approved by the Illinois environmental protection agency, and the city engineer. Before recommending approval of a subdivision, the plan commission must consider the availability of sewage disposal facilities to the proposed subdivision. Regardless of the location or lot size, a subdivision will be disapproved if the city engineer finds that the drainage, soil conditions, disposal facilities or other conditions may create a hazard to public health.
(B) Public Sewer Systems: The facilities on the site must be designed and installed to connect to the public sewer system with the approval of the city engineer according to the requirements of this section, unless an individual sewage collection and disposal system is permitted under subsection (C) of this section.
(C) Individual Sewage Collection And Disposal Systems: The city requires that lots be serviced by public sewage collection and disposal systems. The city council will not consider approval of a preliminary plat or building permit for lots that are not proposed to be serviced by public sewage and disposal facilities unless no public sewer is available within two hundred feet (200') to the nearest point of the closest lot of the proposed subdivision and written approval for construction of such facilities have been provided by Bureau County health department. Any request for individual sewage collection and disposal systems must be approved by the Bureau County health department and Illinois private sewage disposal code which control their design. Where septic systems and individual wells are approved by the city and county, data regarding their location and construction specifications must be included on the final plat as required by this title.
(D) Sewer System Design And Construction:
1. Sanitary sewers and services of approved design and capacity with a minimum earth cover of three feet (3') must be provided to serve all lots and to provide for reasonable expansions of the system.
2. Sanitary sewers must be designed using the criteria of the state of Illinois department of health and the Illinois environmental protection agency.
3. Sanitary sewer manholes must be located at points that will minimize the possibility of submergence in storms. (Ord. 1379, 6-9-2008)
