<br /> <br /> <br />City of Pleasanton, CA (0012108.00) 3-4 Woodard & Curran, Inc. <br />Pleasanton Long-Term Sewer CIP October 6, 2025 <br />3.3.2 Lift Station Improvements <br />As part of the lift station condition assessment, recommendations for lift station rehabilitation were <br />classified as one of three different criticality levels: <br />• Criticality 3 – the most severe criticality, was defined as Repair/replace immediately because of <br />imminent failure or a safety hazard. <br />• Criticality 2 – was defined as Schedule repair/replacement because the equipment is at or exceeds its <br />useful life or failure would cause operations or safety problems. <br />• Criticality 1 – the least critical, was defined as Repair or replace as part of a long-term program <br />because the equipment is inefficient, worn and nearing its useful life, or is failing but is not crucial to <br />operation or safety. <br />Based on these definitions, all criticality 2 and 3 recommendations were considered Priority A projects. These <br />recommendations included rehabilitation actions for all 11 of the lift stations and range from pulling wires <br />and cutting conduits flush with finished floor to avoid trip hazards to a full lift station replacement (LS-5). A <br />detailed list of recommended rehabilitation actions are included in the Sewer Lift Station Assessment. A <br />summary of the priority A lift station costs is shown in Table 3-2. <br />An additional line item for a condition and capacity assessment of the existing East Amador lift station was <br />assigned Priority A. Based on the most recent capacity assessment, EALS is currently undersized to <br />accommodate the modeled peak wet weather flows. This analysis would allow the City to determine the <br />scope of future improvements required at the lift station. This line item also includes capacity assessment <br />and predesign work for East Amador Relief Sewer (EARS) force main and lift station. This station would <br />operate in tandem with EALS and give the City additional flexibility and redundancy when moving flows <br />from the Eastern sewer shed to the WWTF. <br />TABLE 3-2: PRIORITY A – LIFT STATION IMPROVEMENTS <br />Project Notes Estimated Total <br />Capital Cost <br />LS-02, -07, -08, -10 Improvements Includes all criticality 2 and 3 projects identified <br />in the Sewer Lift Station Assessment report <br />$1,420,000 <br />LS-04, -12, -13, -15 Improvements $940,000 <br />LS-05 Full Replacement Project <br />At the time of this project, a redundant siphon <br />will also be installed. Costs include demolition of <br />the existing station and assumes full <br />replacement, including cutover costs from the <br />old to new station. <br />$6,120,000 <br />EARS and EALS Condition <br />Assessment, Capacity Evaluation, <br />and Predesign <br /> $500,000 <br />Page 230 of 323
