"Evapotranspiration (ETo)" means the quantity of water evaporated from adjacent soil and other surfaces and transpired by plants during a specified time period. ETo is expressed in inches per day, month, or year and is an estimate of the ETo of a large field of four inch to seven inch tall, cool season turf that is well watered.

"Invasive species" means species of plants not historically found in California that spread outside cultivated areas and may damage environmental or economic resources.

"Irrigation audit" means an inspection which includes an in depth evaluation of the performance of an irrigation system conducted by a certified landscape irrigation auditor.

"Public water purveyor" means a public utility, municipal water district, municipal irrigation district, or municipality that delivers water to customers.

"Recycled water" means wastewater that has been treated at the highest level required by the California Department of Health Services for water not intended for human consumption.

"Reference evapotranspiration" means a standard measurement of environmental parameters which affect the water use of plants. Reference ETo is used as the basis of determining the MAWA so that regional differences in climate can be accommodated.
