DisclaimerThis 2020 UWMP Guidebook was prepared by the California Department ofWater Resources to aid urban water suppliers who must comply with therequirements of the California Water Code Section I, Part 2.55 and Part 2.6.Urban water suppliers subject to the requirements are solely responsible forcompliance with the requirements and may use this Guidebook if theychoose. DWR has voluntarily opted to provide this Guidebook to makecomplying with the California Water Code simpler for urban water suppliers,and to assist these suppliers in creating a useful planning document.For assistance interpreting the content of this document, please contactCalifornia Department of Water Resources Water Use Efficiency staff atUWMPhelp@water.ca.gov.
PrefaceThe 2020 Urban Water Management Plan Guidebook (Guidebook) is offeredto help Suppliers prepare their UWMP in a way that is consistent with thelegal requirements. It also provides guidance for preparing an “enhanced”planning document that may be more useful to Suppliers, other resourceplanners, or policy and decision makers. This Guidebook has been revisedfrom the 2015 version to reflect the changes in law, recommend analyticalprotocols, reflect variations between the 2015 and 2020 cycles, and toimprove the guidance based on feedback from urban water suppliers andother stakeholders. The 2020 UWMP Guidebook has been updated from the2015 Guidebook to reflect the new legislation, and to potentially improve theusefulness of a Supplier’s 2020 UWMP. To remain consistent with the 2015UWMP guidebook, this 2020 UWMP Guidebook is structured by topic andwritten in the order recommended for Suppliers to organize their ownUWMP.New to this Guidebook is that each chapter includes an introductory sectionto describe the purpose and importance of covering the topic (Importance),how to focus on the essentials required (Focus), how to enhance coveringthe topic using recommended and best practices (Enhancements), and newrequirements since the previous 2015 UWMPs (New Requirements).Associated workbooks and tools are provided to assist Suppliers in preparinginformation for electronic submittal through DWR’s WUE Data Portal. ThisGuidebook will reference these tools and workbooks as described below.SBx7-7 Verification Form. Each Retail Urban Water Supplier must implementgoals of the Water Conservation Act of 2009, also known as the SB X7-7, toreduce urban per capita water use by 20-percent by December 2020. Tocomply, Retail Suppliers that are preparing a 2020 UWMP must provide abaseline and urban water use target in GPCD.SBx7-7 2020 Compliance Form. This workbook includes the series of tablesto show compliance with the goals of the Water Conservation Act of 2009,also known as the SB X7-7, to reduce urban per capita water use by 20percent by December 2020.Submittal Tables. This workbook includes the DWR standardized submittaltables updated for new legislation and dates. Those tables applicable toretailers or wholesalers only are labelled with an R or W, respectively. Thosetable names without an R or W apply to both retailers and wholesalers.Potable and non-potable versions of Submittal Tables are offered in this
workbook as optional for the Supplier’s planning purposes. All are marked asoptional.Energy Use Tables. This offers a selection of tables from which Suppliers canchoose for structuring the required information on energy use. See Chapter6 of this guidebook and Appendix O for specifics. The tables used bySuppliers would be included as part of the narrative of their UWMP (or as anappendix) and the filled-out table or tables would be uploaded as an excelworkbook attachment to the UWMP into the WUE Data Portal.Planning Tool. This workbook tool is an optional tool Suppliers can use toreport and assess water use and supply and conduct the ReliabilityAssessment and Drought Risk Assessment on monthly to annual timeincrements. Results from this tool can be used to populate the SubmittalTables.Potable and Non-Potable Planning Tool (P-NP Planning Tool). This workbooktool is the Planning Tool that allows for separate reporting and calculationsof potable and non-potable use and supplies. Results from this tool can beused to populate the optional potable/non-potable Submittal Tables.
