Water Conservation

CA Drought

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.

The City does not own or operate water services within Rosemead. For more information regarding water-use restrictions and watering schedules, please contact your water service provider for your area.
