WATER SYSTEM MANAGEMENT PLAN OCTOBER 2024 / CAROLLO <br />CITY OF PLEASANTON WATER SYSTEM MANAGEMENT PLAN 18 <br />8.1.2 Water Conservation and Water Loss <br />Carollo also developed a Water Conservation and Water Loss technical memorandum. Part of the new <br />California water loss regulations revolves around data accuracy, leak detection, and water loss reduction <br />through mitigation of water system leaks. The project recommendations from this memo include: <br /> WC-1 Water Meter Testing Program: The City should implement a water meter testing program to <br />build accuracy in water usage data. The City can contract this service or train staff to conduct the <br />meter testing program. <br /> WC-2 Water Conservation Program: This project includes funding for unknown changes and <br />modifications to the current water conservation framework for California. Many of the current <br />regulations are in draft form and things are changing annually. <br /> WC-3 Water Loss Program: The water loss regulations require full system leak detection every three <br />years until compliance with the water loss standards. Leak Detection includes a complete system <br />survey of all the City's pipelines before the compliance date of January 2028. <br /> WC-4 Systematic Data Handling Error Audit: This project included the evaluation of the City’s water <br />meter data collection and handling program. This program will determine if errors in data collection <br />are occurring and will develop programs to mitigate the issues. <br />8.1.3 Repair and Replacement Assessment <br />The condition assessment program identified additional evaluation needs associated with water system <br />assets. <br /> RR-4 Tank Inspection Program: Costs associated with the internal inspection of the City's storage <br />tanks and reservoirs. This project was included in the long-term CIP as a project. <br /> RR-17 Asset Management: The City is currently developing a City-wide asset management program. <br />This project is to fund for the development of the water utility elements of the asset management <br />program and to coordinate with the City-wide efforts. <br /> RR-18 Corrosion Protection: The City should implement a program to establish a corrosion <br />protection strategy for water distribution piping and O&M program for steel tanks (i.e. monitoring <br />and maintenance of cathodic protection systems). <br />8.1.4 O&M Review <br />Carollo conducted an O&M review based on the City's existing California Division of Drinking Water <br />(DDW), and water utility best practices. Details on the O&M review are included in the Operations, <br />Maintenance, and Management, of the Water Distribution System Technical Memorandum in Appendix E. <br />The project and program recommendations include the following: <br /> OM-1 Unidirectional Flushing Program: Develop a single unidirectional flushing program. Valve <br />exercising and hydrant maintenance to be integrated with flushing program. <br /> OM-2 Utility Training Program: Incorporate/implement utility training program recommendations <br />prepared by DKF into overall Public Works training program and continue to develop elements <br />including SOPs and training materials. Costs shown are water related only (does not include sewer <br />and storm related tasks). <br />Page 449 of 658
