MWM has been working with urban water management plans since 2000. We have been involved in plans with the City of Sacramento (2000), Calistoga (2005), Suisun-Solano Water Authority (2005, 2010, 2016), South Tahoe Public Utilities (2010), Liberty Utilities (2016), Mid-Peninsula Water District (2016), City of Sonoma (2016) and technical demand analysis portion of the UWMPs for over 57 agencies, including Marin Municipal Water District, North Marin County Water District, City of Santa Rosa, City of Petaluma, City of Rohnert Park, Town of Windsor, City of Sonoma, Valley of the Moon, City of Cotati. (2005-2016). Please find 2015 UWMPs at the following DWR link: View Reports
MWM updated the projected demands for the four water retailer agencies in the Santa Clarita Valley served by Castaic Lake Water Agency. This project was implemented in a two-phase approach and completed in 2015. The first phase included a “top-down” approach to review and update the forecast of future demand using revised population estimates from the 2010 Urban Water Management Plan (UWMP) and the population validated from the Population Assessment project completed by MWM in June 2014. Phase 1 demand forecasts were also adjusted to normalize for the influencing factors of the economy and weather. A second phase was performed to review a different planning perspective using a land-use-based demand forecast with a “bottom-up” approach based on retail agency provided information. The goal of this effort was to finalize demand forecasts for each retailer agency and CLWA to comply with the 2015 Urban Water Management Plan Act.
In 2016, MWM produced the 2015 UWMP for Cambria Community Services District (CCSD), completing the project in December 2016. The intent of the UWMP was to provide DWR and the public with information on present and future water sources and demands and to provide an assessment of CCSD’s water resource needs. Specifically, the UWMP provided water supply planning for a 20-year planning period in 5-year increments; identified and quantified adequate water supplies for existing and future demands during normal, dry and drought years; and assured efficient use of urban water supplies.
2016, MWM provided services to assist Cambria Community Services District with the completion of an Environmental Impact Report (EIR). Services involved a review of Cambria’s historical demands, historical conservation activity including local plumbing codes, and the collaborative development of projected water use and demand management measures creating an update to Cambria’s DSS Model. A detailed review of Cambria’s population and employment status and local codes and ordinances was also conducted.
This Water Use Efficiency Plan identified programs and projects to most effectively meet Liberty Utilities’ water use requirements. With the use of MWM’s DSS Model, the plan provided detailed information for 19 individual conservation measures, giving Liberty the flexibility to use this plan as a guide to implement additional measures to manage water savings. This Plan illustrated that expanded water conservation efforts by Liberty Utilities/Apple Valley were a feasible and cost-effective means of assuring adequate future water supplies. Liberty Utilities/Apple Valley plans to continue to use conservation to meet their per capita consumption targets as reported in their 2015 Urban Water Management Plan. This Plan outlined a program that will focus on following the Best Management Practices as defined in the original California Urban Water Conservation Council (now California Water Efficiency Partnership or CalWEP) Memorandum of Understanding (MOU), Exhibit 1, along with Liberty Utilities/Apple Valley’s Public Utility Commission regulations and water use targets for the year 2020 as set forth in Senate Bill X7-7 (SB X7-7).
Representing the interests of 26 member agencies that purchase water wholesale from the San Francisco regional water system, BAWSCA wanted to update their demand and water efficiency goals. Key components of the plan included:
The benchmarking survey focused on quantifying the costs, savings and scope of a successful long-term water efficiency program. The report answered typical agency questions such as: “What is everyone else in the industry doing?”; “Are there any new ideas I have not considered?”; and “How much should I budget for a successful conservation program?” The answers were presented in summary tables with real data on what the leading conservation agencies in the nation were currently doing.

Maddaus Water Management has been working with Metropolitan North Georgia Water Planning District for the past 14 years. Four separate reports have been released since 2003 summarizing analysis results. For the current effort in 2016, Michelle Maddaus is Project Manager for the Water Conservation and Demand Analysis update to be released in 2017. Michelle trained, managed and performed QA/QC for the four-member modeling team to update the DSS Models. The models were updated using new water use data and new regional population projections. In the 16-county area, there are more than 25 water-providing agencies and more than 30 water treatment plants. The area currently uses an average of nearly 700 million gallons per day of water.
MWM completed a technical analysis and created a plan to replace the Interim Water
Conservation Plan that was included as part of the 2010 Urban Water Management Plan.
The technical analysis was conducted using the DSS Model.

MWM assessed the City’s water use patterns and trends and the conservation potential;
reviewed its water conservation program; in conjunction with another firm, prepared
a water conservation chapter in the overall water supply study report; and recommended an approach to developing a water conservation plan for the City. Later, MWM detailed evaluation of water savings, costs, and benefits from additional water conservation programs.
