<br />observers for up to two days of field time to assist with field data collection and to review and <br />advise on test procedures. <br /> <br />. Budgeting includes equipment rental, including shipping, for a one-month rental for 16 flow <br />monitors to be installed at 9 SFPUC turnouts (turnouts supplying City Main Zone and Redwood <br />Shores). Budgeting assumes that meters would be installed by City or SFPUC staff and that City <br />will coordinate with SFPUC. <br /> <br />. City will provide SCADA data in electronic format, such as csv files or Excel data files for <br />hydrant flow testing program, diurnal curve development and review of peak factors. <br /> <br />Task 7 Hydraulic Analysis <br /> <br />Objective: Use the hydraulic model of the City distribution system to analyze the existing distribution <br /> <br />system and identify improvements that provide appropriate volume, pressures, and storage for the existing <br />system and system at buildout demands. <br /> <br />TASK 7.1 DEVELOP WATER SYSTEM PERFORMANCE CRITERIA, SERVICE STANDARDS AND <br />LEVEL OF SERVICE GOALS <br /> <br />This task will establish water system performance criteria, service standards and level of service goals for <br />the hydraulic analysis of the system. This effort will be specific to the hydraulic evaluation, but will be <br />coordinated with the overall system level of service goals established in Task 10. The foundation for the <br />assessment of the City's water system requirements will be an updated version of the City's overall water <br />system service and performance standards. WY A will review the City's previous facility planning efforts <br />as well as other available documents, including California Code of Regulations (Title 22, Chapter 15), <br />California Fire Code, EPA's Finished Water Storage Facilities and A WW A Manual 32-Distribution <br />Network Analysis for Water Facilities, to compile and summarize a list of industry standards upon which <br />to base/compare to the City's existing water utilities planning and system performance criteria. These <br />criteria will include: <br /> <br />. Minimum storage volumes required for operational, fire and emergency storage. <br />. Maximum allowable pipeline velocities (under different demand conditions). <br />. Maximum allowable pipeline head loss (under different demand conditions). <br />. Required fire flows/duration by land use type. <br />. Minimum/maximum pressures under different demand conditions. <br />. Pump station capacity and redundancy requirements. <br />. Emergency groundwater storage credits. <br />. Minimum desired and required chlorine residuals. <br /> <br />Fire flows will be determined based on review of the local fire codes, input from City fire marshal, and <br />engineering and operational staff, and will reflect fire flow demands for residential, commercial and <br />industrial customers. <br /> <br />WY A will compare existing criteria for fire flow rates and duration, reliability, and current per capita <br />water usage/demand to generally-accepted water industry standards and review them with City staff. <br /> <br />October 22,2009 <br /> <br />10 <br />
