Wastewater <br /> This section of the CIP describes projects associated with the local collection and transmission of <br /> wastewater from Eugene to the regional water pollution control facility owned and operated by <br /> the Metropolitan Wastewater Management Commission (MWMC). Projects associated with the <br /> regional water pollution control facility and other regional facilities are a part of the MWMC <br /> Capital Program. The Capital Improvement Program for Wastewater is supported by the 1992 <br /> Urban Sanitary Sewer Master Plan. This plan identifies future needs and estimates the costs to <br /> extend service to developing areas within the Urban Growth Boundary (UGB). The plan also <br /> includes recommendations for rehabilitation of existing systems and management of infiltration <br /> and inflow (I&I) entering the wastewater collection system. <br /> The I&I program (Wastewater System Rehabilitation) is a strategic approach designed to reduce <br /> or limit the amount of groundwater/rainwater flow that is treated at the regional wastewater <br /> treatment plant as well as retain the carrying capacity of the collection system and maintain the <br /> infrastructure. Currently, illicit connections to the wastewater system or deterioration of the <br /> collection system (open joints, cracks, etc.) are allowing excessive groundwater or rainwater to <br /> enter the system. This reduces the carrying capacity of the collection system and contributes to <br /> large peaks in the flows that are treated at the wastewater treatment plant. The Wet Weather <br /> Flow Management Plan (~JVWFMP) reinforces a focus on I&I reduction through rehabilitation of _ <br /> the existing system. The WWFMP also recommends the development of a program to address <br /> the private portion of the collection system; the community sewers rehabilitation program is a <br /> first step in that effort. <br /> The WWFMP for the wastewater system serving the Eugene/Springfield metropolitan area was <br /> adopted by the Metropolitan Wastewater Management Commission in the winter of 2001 and <br /> accepted by the City Council of Eugene shortly thereafter. A citizens committee and open <br /> houses were utilized during the development of the plan. Elements of the study reinforce the <br /> recommendations for rehabilitation in the Urban Sanitary Sewer Master Plan. <br /> Project Categories <br /> <br /> Wastewater projects are described in one of two ways: <br /> 1. Preservation and Maintenance -The wasterwater system rehabilitation projects focus <br /> on inflow and infiltration (I&I) in our aging system. In addition to reduction of I&I to <br /> keep overall collection and treatment costs down, the I&I program protects the public's <br /> investment in existing facilities where routine preventive maintenance activities are no <br /> longer cost-effective. These projects are funded by user fees and by the reimbursement <br /> component of the wastewater system development charge. The pump station <br /> rehabilitation projects are to upgrade older pump stations to increase efficiency and to <br /> lower operation costs. The community sewers rehabilitation program will provide <br /> wastewater systems adjacent to properties to reduce inflow and infiltration and <br /> operational problems. All of the projects in the preservation and maintenance category <br /> have an element that will provide additional capacity as a result of the increase in <br /> efficient operations or reduction in I&I, but the primary focus of the projects is to <br /> preserve and maintain the facility. <br /> City of Eugene 2006 - 2011 Capital Improvement Program <br /> 158 <br /> <br />
