Help the District Meet the 20% in 2020 Conservation Goal

The State of California’s Water Conservation Act of 2009 required water agencies to reduce water consumption 20% by 2020.  In order to meet that goal, the District’s Stage 2 Water reduction goals are now in effect. Following is a list of key elements that impact most customers with a link to the full list below.

The District always operates at a Stage 1 level, which includes basic good practices and helps prevent waste. The Stage 2 regulations include conservation measures and use requirements to help the District meet the 20 percent reduction goal. View the full list of regulations for each stage.

20% by 2020 - How are we doing?

The 20% by 2020 state mandate requires all water purveyors reduce their per capita water use by 20% from a baseline calculated by averaging customer usage over 10 years in the early 2000s and accounting for water leaks. In addition to customer water conservation efforts, the District's waterline replacement and water leak detection/repair projects will also help to bring the District into compliance. If the District (or any water purveyor) fails to meet this 20% by 2020 mandate, the State has indicated that we will no longer be eligible for state grants.

The graphic below shows the average annual consumption since 2000, the District baseline (red line, the average across the 10 years), and our 2020 requirement (green line). The District met our 2015 target in no small part due to limited watering days. However, the District is falling short of its target, so we must make one final conservation push in order to meet the state requirements.

What can I do to help? 

As indicated in the graph below, the District and our customers are not meeting the state’s mandates. Not meeting these requirements will impact the District’s ability to secure grant funding in the future.  By following the District’s water conservation guidelines, especially those related to outdoor water usage and restricted watering days, we should be able to meet these mandates.

Water Conservation Regulations & Restrictions Details



Adoption of the District’s Water Ordinance in November 2019 included new Water Conservation regulations. The District operates in Water Conservation Stage 1 under normal conditions. These regulations reflect the underlying intent of the ordinance that water should not be used in a manner that is wasteful or without a reasonable purpose and ensure the most efficient use of the District’s water resources and to enable the system to be operated in the most cost-effective manner for the benefit of all residents.

At the March 10, 2020 Board of Directors Meeting, the Board declared Stage 2 of the District’s Water Conservation Ordinance, which sets a 20% reduction goal. This goal is in line with the Water Conservation Act of 2009, which requires water agencies to establish water use targets that will result in a statewide saving of 20% by the year 2020. The California Water Code 10608 also requires the District to meet 20% reduction targets.  If the District does not meet the 20% reduction mandate, state water funding will no longer be available to the District.  In addition to the funding to provide water conservation rebates to our customers, the District has also received funding to improve irrigation at North Tahoe Regional Park and other capital projects.
