• r_ <br /> City Responsibilities: <br /> 1. Provide any information requested from its files and will assist as necessary in <br /> obtaining information from other agencies. <br /> 2. Operate the existing lift station in the presence of the Engineer. <br /> 3. Perform confined space entry inspections if necessary. <br /> 4. Provide personnel and equipment to perform pump tests (pressure and flow) at the <br /> existing station. <br /> 5. Provide access to the site and building and perform equipment operation. <br /> Deliverables: <br /> 1. Provide copies of all collected and developed information as requested by the City. <br /> Task 3—Design Criteria Development <br /> This task provides for the development of the design criteria for the lift station replacement. <br /> The key issues will be summarized and the replacement station concepts and alternatives to <br /> be examined in subsequent tasks will be identified. The detailed subtasks are as follows: <br /> MSA Responsibilities: <br /> 1. Review and Clarify City Standards— Obtain and review City lift station design and <br /> telemetry standards and other relevant design references. Meet with City staff to <br /> review and clarify the City's design requirements. Establish City preferences with <br /> respect to equipment selection, instrumentation and controls, system control <br /> strategies, station appurtenances, site amenities, and other replacement station <br /> functions and features. <br /> 2. Update Service Area Characteristics and Design Flows—In a collaborative effort with <br /> City staff, review pending service area changes as related to annexations, changes in <br /> the service area of the Alderwood Water and Wastewater District, and potentially <br /> other changes. Document the revised service area and its characteristics. Based upon <br /> the revised service area, establish revised design pumping rates at present, in 20 years, <br /> and at buildout. The City will conduct system modeling as needed to assist in this <br /> work effort. Contrast the revised flow rates to those in the Comprehensive Sewer <br /> Plan. Also evaluate and define the maximum or optimum capacity for the lift station <br /> and force main combination independent of service area. <br /> 3 <br /> City of Everett MURRAY,SMITH&ASSOCIATES,INC.
