Y o <br />1.1.2 Rates For Existing. Development <br />1.1.2.1 Single Family Dwellings 8~ Duplex <br />For existing single family dwellings the local wastewater charge is the <br />rate for one EDU. For an existing duplex developments, the charge is <br />equal to two times the .rate for one EDU. <br />1.1.2.2 All other development with wastewater discharge. less <br />than 100,000 gallons per day <br />For administrative convenience, rather than verifying by physical <br />inspection the numbers of plumbing fixture units in existing development <br />that is connecting to the wastewater for the first time, the local <br />wastewater SDC shall be determined by using the historic winter water <br />consumption for the existing development. The existing development's <br />consumption for the preceding months of December through April is <br />totaled and averaged and the resulting average is multiplied by the rate <br />per 1,000 gallons. The rate per 1,000 gallons is based on an assumed <br />typical single-family dwelling average winter water consumption of 6,000 <br />gallons per month, and is calculated by dividing the EDU rate by 6: <br />1.1.2.3. Large Volume Users with wastewater discharge greater <br />than 100,000 gallons per. day <br />For existing development with measured or proposed total flow greater <br />than 100,000 gallons of water discharged per day, the .local wastewater <br />charge is equal to the total amount of water being discharged per day <br />(Total Flow), divided by the presumed continuous EDU flow estimate, <br />multiplied by the rate for one EDU.. The presum~d'continuous EDU flow <br />estimate (average gallons per day) represents the assumed daily flow of <br />a-typical EDU, if continuous consumption occurred over a 24 hour <br />period. The presumed continuous flow measure is estimated as 600 <br />gallons per day. <br />Attachment #4 of Exhibit A <br />Administrative Order No. 58-96-06 <br />Page 2 of 5 <br />1.2 <br />Formula for the River Road/Santa Clara/HWY 99 Areas/Highway 99 Areas <br />This charge would be classified as a reimbursement for the City's. portion of the cost of <br />that area's sewer system. The charge is based on the trunk sewer, pump station and <br />force main costs in the area net of federal grants and. equivalent assessments and the <br />developable acres in the area. <br />July 01,'1996 <br />Methodologies: City of Eugene <br />Page D-5 <br />
