Section 2. Southeastern Oakland County Sewage Disposal System. A. Sanitary Wastewater Disposal Charge. • (a) Water consumption information for each city is gathered from three (3) sources - The Detroit Water and Sewer Department, the Southeastern Water Authority, and the individual municipalities. This information consists of meter readings of the various master water meters serving the S.O.C.S.a.S. communities. From these meter readings the water consumption of each municipality is determined. That consumption is the basis for sanitary wastewater disposal charges using rate per one thousand (1,000) cubic feet established from time to time by the Drain Commissioner, (b) Where communities have individual sewer customers with metered sewage, permitted and approved in accordance with the provisions of, Article .V of these Regulations, then each community shall also report within fifteen (15) days following the end of each calendar quarter the total metered sewage within the community, in lieu of water consumption. Based on the quarterly report, each community shall pay a charge per one thousand (1,000) cubic feet of metered sewage, as established from time to time by the county. The rate for sewage disposal based on the metered sewage-method shall be one hundred ten (110) percent of the rate established for the master meter water method. B. Storm Water Disposal_Charae. The Southeastern Oakland County Sewage Disposal System serves a district of approximately 46,000 acres with approximately 24,400 of those acres being a combined sewer area. During dry weather flow, all sewage is piped to the City of Detroit for treatment. During storm events the district is only allowed to send 260 cubic feet per second to the City of Detroit for treatment. The district maintains the Pollution Control Facility, a treatment and retention facility, to hold excess combined sewage to its capacity during these storm events and later pumps this combined .sewage to Detroit for treatment. A storm water charge is imposed on those communities within the district that have combined sewers. -33- The storm water charge is based upon the total acreage within the community which is. served by combined sewers and a runoff coefficient assigned to the land use for that acreage. From these two factors the district has established a percentage of storm water contributed by each community within, the district. That percentage is applied to the master meter reading less the water sales billed to determine the volume of storm water to be paid for by each community. The cost of operating and maintaining the Pollution Control Facility added to the charges imposed by the City of Detroit for treatment of the storm water . establishes the total cost for storm .water treatment to those contributing. Therefore, the storm water disposal charges are determined using a rate per 1000 cubic feet established from time to time by the Drain Commissioner. C. High Strength Surcharge.
