WPCF Headworks Replacement Project Scope of Work <br />36 <br /> <br /> Review the 2024 Sewer Comp Plan to identify forecasted plant flow conditions. The 2014 <br />Sewer Comp Plan will be reviewed and references as needed. <br /> Develop process flow diagram for the existing and new headworks, as required to establish <br />flows for the new headworks. Include bypassing procedures and flows for the new facility. <br /> Confirm the forecasted plant influent flow and develop flow design criteria that will serve as <br />the basis of design for the new headworks facility. <br /> Review the 2022 WPCF Facility Plan and available Nutrient Reduction Evaluation documents <br />the alternatives analysis <br />and equipment selection. <br /> Integrate findings from this task into the Process Sequence and Design Criteria workshop <br />completed under Task 403. <br /> Establish additional key process design criteria, including screenings solids loading, grit <br />production rates, and septage receiving station capacity. Define upstream and downstream <br />hydraulic constraints for the new facility based on existing system conditions. <br />Task Assumptions <br /> No system-wide collection system modeling will be completed under this task. <br />City Responsibilities <br /> Provide historical plant flow data and planning documents as requested from the design <br />team to inform headworks flow criteria. <br /> Provide documentation developed for the Nutrient Reduction Evaluation as needed to inform <br />Phase 400 alternatives and equipment selection. <br />Meetings <br /> Findings from this phase will be presented in the Process Sequence and Design Criteria <br />workshop completed under Task 403. <br />Work Products <br /> None <br />Deliverables <br /> None (workshop materials provided under Task 403) <br />Task 403 Workshops/External Meetings <br />Objective: This task covers workshops that will be conducted throughout Phase 400. These <br />workshops will be structured to summarize work completed under individual listed alternatives <br />analysis topics and organized to solicit City feedback, receive design input, and document decisions <br />for the topics. Design team workshop attendance and workshop notes are covered under this task. <br />Specific workshop materials will be developed. The following table summarizes the intended <br />workshops, anticipated number of attendees, and assumed duration. <br />
