4. Approving Evergreen Sewer Rates for Fiscal Year 2005-2006DATE: August 3, 2005 TO: Jim Patrick, City Manager Mayer Kennedy & City Council Members FROM: Rick Wills; Deputy Finance Officer RE: Evergreen Sewer Rate for Fiscal Year 2005/2006 Please find attached several sheets of information. This compilation is for the Wastewater Treatment Plant operations only and does not include the billing costs, bad debt expense, depreciation or sanitary sewer expenses. The first skeet is a compilation of the expenses of the WWTP for the fiscal year 2005. Our operating expenses increased by about 8% from the prior year. FY2004 expenses are included for comparison. The City spent $96,534 on the plant expansion/rate study/facility plan. The City also spent $17,804 on consultants regarding the feasibility of extending sewer lines north of Kalispell along Whitefish Stage Road. These expenses were not used in the formula for Evergreen's FY 2006 r�.�G. af,Gy uv Elul xlitpa44 lxi4ir 4VlilGf44 vr.A4xx 4114 �.a43' uxtu •.r4e�jx4s.le a 4a�u4x4y E4xxiuxGxa unchanged. Evergreen Sewer District's FY2006 rate is based on our operational expenses for FY2005 prorated at the percent of usage based on meter readings at the lift station and the plant. A page is attached with the meter readings and usage. Evergreen's usage is up almost 6%, while the total plant usage is up 6.45%. As a result, Evergreen's share of the total flaws has decreased from 16.78% to 16.68%. This is not a percent of capacity only a percent of flows treated at the plant. The percent of usage (16,68%) is applied to our operating expenses and replacement fund requirements to arrive at the total cost for treating Evergreen's sewage. The cost is then divided by their gallons of usage to arrive at the rate per thousand. This calculates to $1.36 (down $0.01 from FY2005) per thousand and is the new rate for FY2006. The district pays 22% of the debt service casts regardless of the usage. The Evergreen debt service expense for FY06 is $9,317.57 per month, down from $9,715,03 for FY05. The amended Evergreen agreement calls for Evergreen to share in the equity of the WWTP Replacement .Reserve account. A reconciliation of the reserve account is included. The items for which replacement funds were used are listed on the reconciliation page. The account earned $8,677.61 in interest. The equipment replacement schedule was adjusted for the items listed on the sheet for the reconciliation of the reserve account. Evergreens total equity in the replacement reserve account is $516,550.52. 2005 WWTP... FISCAL YEAR 2005 Wages/ficalmedt/wc/unemp. Overtime Health Ins.
