Urban Water Management Plans
The Urban Water Management Planning Act (California Water Code Section 10610) states that every urban water supplier that provides water to 3,000 or more customers, or that provides over 3,000 acre-feet of water annually, should make every effort to ensure the appropriate level of reliability in its water service sufficient to meet the needs of its various categories of customers during normal, dry, and multiple dry years. To meet these requirements, an effective Urban Water Management Plan (UWMP) is developed to meet the following objectives:
- Accomplish water supply planning over a 20-year period in 5-year increments
- Identify and quantify adequate water supplies, including recycled water, for existing and future demands, in normal, dry, and drought years
- Implement conservation and efficient use of urban water supplies
The Urban Water Management Planning Act also requires urban water suppliers to update their UWMP and submit a complete plan to the Department of Water Resources every five years. The UWMP is required in order for a water supplier to be eligible for Department of Water Resources administered State grants, loans and drought assistance. The UWMP Act requires urban water suppliers to report, describe, and evaluate water deliveries and uses, water supply sources, efficient water use, and demand management measures.
According to the requirements, the next significant UWMP update should be completed by July 1, 2016. The 2015 UWMP Guidebook, in its draft state, was released in November, 2015 and is scheduled for a final draft release in January, 2016.
The 2015 UWMP update will require implementation of new and revised regulations since the 2010 update. Below are a few of the most notable proposed changes to the 2015 UWMPs that are likely to impact your next update:
AB 2067 (Weber)
- Revised UWMP Due Date: July 1, 2016
- Demand Management Measures (DMMs)
- Based on recommendations made by the ITP (Independent Technical Panel), the 2015 UWMP update will be required to provide a narrative description addressing the nature and extent of each DMM implemented over the past five (5) years, from 2010 to 2015.
- Where, nature is a description of the DMM program and extent is the quantification of the implementation of the DMM.
- Number of DMM categories have been reduced from 14 to 7 for retailers and reduced to 4 for wholesalers.

SB 1420 (Wolk)
- Requires the UWMP to quantify and report on distribution system water loss over the most recent 12-month period.
- Authorizes water use projections to account for estimated water savings as a result of adopted codes, standards, and ordinances.
- Requires the plan, or amendments to the plan, to be submitted electronicallyto the DWR and include any standardized forms, tables, or displays specified by the DWR.
SB 1036 (Pavley)*
- Energy Intensity Estimation/Calculation
Since 2005, Risk Management Professionals (RMP) has developed and coordinated numerous UWMPs, which have included water supply and demand projections and assessments of water supply reliability during normal, dry, and multiple-dry years. In addition, the plans have emphasized water conservation, monitored the implementation of DMMs, described planned water supply programs, investigated opportunities for utilizing recycled or desalinated water, and included extensive public participation and agency coordination.
RMP has evaluated and modeled the sufficiency of the sources utilized by the urban water suppliers (e.g., groundwater, wholesale) and worked extensively with local stakeholders to ensure the UWMPs were synchronized with regional and local plans.
