Water Conservation

CA Drought

On March 24, 2023, Governor Newsom issued the latest Executive Order N-7-22 that eases drought emergency provisions due to current water conditions. Executive Order N-5-23 maintains certain measures that support communities still facing water supply challenges, and in hopes of building up long-term water resilience.
While recent storms have helped ease the immediate drought impacts, some regions and communities across the state continue to experience water supply shortages. Communities that rely heavily on groundwater supplies depleted from overreliance and successive multi-year droughts will continue to observe conservation measures.


On March 28, 2022
, Governor Newsom issued Executive Order N-7-22 calling on urban water suppliers to implement actions to reduce water usage by 20-30 percent, depending on local conditions. In response, water usage goals and measures have been designed to achieve reductions due to the water supply shortage. By making simple changes in your daily routine you can help make a positive impact on water conservation.
