A. Purpose: This chapter sets forth uniform requirements for users of the POTW for the City of Rigby and enables the City to comply with all applicable State and Federal laws including the Clean Water Act and the General Pretreatment Regulations (40 CFR, Part 403). The objectives of this chapter are:
1. To prevent the introduction of pollutants into the POTW that will interfere with the operation of the POTW;
2. To prevent the passage of pollutants through the POTW, inadequately treated, into receiving waters or the atmosphere or otherwise be incompatible with the POTW;
3. To improve the opportunity to recycle and reclaim wastewaters and sludges from the system;
4. To protect POTW personnel who may be affected by wastewater and sludge in the course of their employment and to protect the general public;
5. To establish an equitable distribution of the cost of operating the POTW;
6. To establish an equitable means, through the collection of a sewer main connection fee, of requiring persons connecting to an existing sewer main which directly benefits their property, to participate in the costs of installing such main; and
7. To establish an equitable means through a sewer service connection fee of requiring persons who connect to the sanitary sewer system and the wastewater treatment section 8-1-5 plant to participate in the capital costs of constructing the entire system and to pay the direct costs of making such connection.
