~~ <br />,, <br />Wastewater <br />The Capital Improvement Program for Wastewater is supported by the Urban Sanitary Sewer <br />Master Plan (completed in 1992 by the Department of Public Works, Engineering Division), <br />and reviewed by the Council Committee on Infrastructure. This plan provides for future <br />needs, and estimates the costs to extend service to growth areas within the Urban Growth <br />Boundary. The plan also includes recommendations for rehabilitation of existing systems and <br />management of infiltration and inflow (I & I) entering the wastewater collection system. <br />Project Categories <br />Wastewater projects are described in one of three ways: <br />1. Preservation and Maintenance -These projects preserve the investment in existing <br />facilities where routine preventive maintenance activities are no longer cost-effective. <br />These projects are funded by user fees and currently reflect the focus on infiltration and <br />inflow reduction; <br />2. Upgrades and Capacity Enhancements - These projects include modification, <br />improvement or expansion of existing facilities; <br />3. New Capital Facilities -These projects result in a new capital asset and generally occur <br />in anticipation of or in response to new development. <br />Funding <br />The wastewater capital program is supported by wastewater user fees, wastewater systems <br />development charges and assessments to property owners. .Currently, these funds are <br />adequate to maintain the existing system as well as support new service areas and the initial <br />phases of the infiltration and inflow program. <br />The infiltration and inflow program is a strategic approach designed to reduce or limit the <br />amount of groundwater/rainwater flow that is treated at the regional wastewater treatment <br />plant as well as retain the carrying capacity of the collection system. Currently, illicit <br />connections to the wastewater system or deterioration of the collection system (open joints, <br />cracks, etc.) are allowing excessive groundwater or rainwater to enter the system. This <br />reduces the carrying capacity of the collection system and contributes to large peaks in the <br />flows that are treated at the wastewater treatment plant. <br />Expansion of the wastewater collection system is financed primarily by Assessments and <br />Systems Development Charges (SDCs) placed on new development. This CIP includes <br />proposed projects that will require the commitment of future SDC revenues to finance. <br />` City of Eugene .1998-2003 Capital Improvement Program <br />Project and Program Areas -Wastewater Sewers <br />60 <br />
