The council finds that it has been collecting sewer user charges for the use of sanitary sewers and sewage treatment plant facilities for the purpose of paying the costs of the financing of such facilities and operation of the sewage collection and treatment system within the city of North Bend, and this chapter is intended to continue to collect sewer user charges for such purposes on the revised basis provided in this chapter. The council also finds that it is necessary in order to protect the waters within and adjacent to the city of North Bend from pollution and to promote the public health, safety and welfare of the residents of and near the city, a sewage system has been developed to be operated by the city for collection, treatment and disposal of wastewater tributary to such a system, and it is necessary in the public interest that the city establish a schedule of rates for sewage collection and disposal in amounts sufficient to pay the expenses of maintaining and operating such facilities and the payment of any outstanding sewer bonds to also provide necessary reserves. The council also finds that it has entered into a grant agreement with the Environmental Protection Agency for the construction of sewage treatment facilities in which the city has agreed that the costs of operating and maintaining the sewage treatment works shall be distributed among all users of such treatment works in proportion to each user’s contribution to the total wastewater loading of that sewage system.
