In 2015, Executive Order B-29-15, tasked the California Department of Water Resources (DWR) with revising the 2010 updated Model Water Efficient Landscape Ordinance (MWELO) to increase water efficiency standards for new and retrofitted landscapes through encouraging the use of more efficient irrigation systems, greywater usage, and onsite storm water capture, and by limiting the portion of landscapes that can be covered in turf. Updating the ordinance to incorporate these elements will help stretch our limited water supplies. The EO also required that agencies report on their implementation and enforcement of local ordinances by December 31, 2015. DWR's Water Use and Efficiency branch worked with several affected agencies, interested groups, and the public to prepare the current (2015) updated MWELO to improve landscape irrigation water savings in accordance with the EO.
