Water Conservation Requirements

MMWD has had water conservation requirements in place for more than two decades to encourage the wise use of our limited water resources. In response to advances in high-efficiency technology and new state regulations, these requirements have been updated several times over the years. These updates help to ensure that MMWD customers benefit from the very best water-saving technologies and practices.

Title 13 of the district's Code, Water Service Conditions and Water Conservation Measures, sets the standards for water use in all new construction, both residential and commercial, as well as certain remodels and landscape rehabilitations. If you are considering a new construction, remodel, or landscape project, please review our Indoor Requirements and Landscape Plan Review Requirements.

Even if you aren't currently considering a project subject to the conservation requirements, we hope you will voluntarily follow these standards in your own home or business. You could see significant savings on your water bill, and you will be helping to ensure a sustainable water supply for the future. Thank you for doing your part!

What's New

Water Conservation Ordinance - Effective December 16, 2015

In response to Governor Brown's Drought Executive Order and new state requirements, MMWD's Board of Directors has adopted Ordinance No. 430. The Ordinance sets new standards for water efficient landscapes, landscape plan review requirements, and kitchen and lavatory faucets. Our Indoor Requirements and Landscape Plan Review Requirements pages have been updated to reflect these changes.  

Graywater Ordinance - Effective February 1, 2016

MMWD's Board of Directors has adopted Ordinance No. 429, which requires applicants for new water service and applicants requesting an enlarged water service for substantial residential or commercial remodels to install a graywater recycling system to reuse the maximum practicable amount of graywater on site. The new requirement supports the district's ongoing efforts to reduce demand on the potable water supply during the current drought and beyond.
