Pis. Miry Butler, Mayor May 16, 1985 Page 2 The reason for the credit is that the Commission underspent its 1984 budget by 5.5%, or approximately $4,650,000.00. The budget was underspent primarily in the areas of contracted services, wages, benefits, materials, supplies, utilities, and chemicals. The Cannission also realized increased revenue from its Industrial Strergth Cderge and Investment Earnings (refer to Attachment C - 1984 Fiscal Report). In addition, the total flow discharged to the MDS in 1984 was greater than estimated by nearly 8%. The increased flow is primarily due to annual precipitation of at least 10 inches above normal for both 1983 and 1984. As shown in Attachment D - Annual Commnity Flows, the total metropolitan area wastewater flow varies nearly +7 percent depending upon the amount of precipitation received in the period prior to and during the year of record. This variation in the wastewater flow is primarily the change in the aneunt of inflow/infiltration (I/I) as a percentage of the total wastewater volume. According to our flaw records, it appears that significant I/I flow is present in your sewage collection system. The volume of I/I flow is minimized when sewers are properly installed and an on -going maintenance program is implemented. The Commission has begun the preparation of the "1986 Statement of Sewer Services Charges" for the 104 communities who discharge to the MDS. The initial step in this process is to estimate the wastewater flow that will be generated by each of these communities in 1986. Based on historic flow records, precipitation trends, and your community's anticipated growth (i.e., 50 residential equivalent connections), the Commission has estimated your community's 1986 flaw to be 225 MG. The Commission has also initiated the preparation of its 1986 Budget. The Budget includes the Cammission's operation and maintenance costs plus the user portion of the debt service necessary to fund existing and proposed capital improvement projects. The 1986 Budget, which will be presented for public hearing this summer, is expected to be approximately 68 greater than the Commission's 1985 Budget. In accordance with State Statutes, the budget will be allocated proportionally to the 104 communities who discharge to the MDS, based on their estimated wastewater flaw. The 1985 wastewater flow estimate for your community is 200 MG (refer to Attachment E - Statement of 1985 Sewer Service Charges). This estimate, which was made in mid-1984, includes the 50 new residential equivalent connections (REC's) that are expected to be added to your sewer system during 1985. Based on the metered flow data from the first quarter of 1985, this estimate appears to be slightly low. Should future flow data indicate a major departure from the flow originally estimated, the Cammission will advise you accordingly.
