MCWD’s water supply shortage level may limit or prohibit installation of landscape. See our Homepage for current water restriction level. Compliance with Town of Mammoth Lakes Water Efficient Landscape Ordinance (WELO) is required for all new irrigation systems and all irrigation systems being modified. Additional information can also be found on the California Department of Water Resources (WELO).

A separate irrigation meter may be required for new installations or modifications. 

Installation of an approved backflow prevention assembly is required for all irrigation systems and must be installed prior to irrigation system connection.

Please take all the above into consideration prior to ordering plants and/or landscape materials and see our Outdoor Conservation and Turf Replacement Rebate Program pages for resources and recommended plant lists.
