About Certification

Become a Certified Water Manager (CWM)

The California Landscape Contractors Association’s Water Management Certification Program was established in 2007 and helps the green industry reduce landscape water usage by certifying individuals through performance-based water budgeting. This unique program carries the WaterSense label from the U.S. Environmental Protection Agency and is also approved for continuing education units by NALP (formerly PLANET), the Irrigation Association and the International Association of Arboriculture.

Certification consists of:

  1. Attendance at the one-day workshop and completion of the irrigation audit introduction. Workshop Dates times and locations are provided here. Watch for new workshop dates. Workshops are typically scheduled from October-May. They will be announced as they become available.
  2. Pass the Written Test with 70% or better (written test typically follows the one-day workshop). Download the study guide for the written test. (To print the study guide, set page scaling to Fit to Printer Margins when you print the document.)
  3. Successful completion of the Performance Program or management of at least one landscape site for a rolling 12 months (this can be achieved retroactively)

Two levels of certification:

  1. Basic Certification: CLCA Water Manager. Pass the written test have completed the water audit training and manage at least one property for one year and continue to manage a property at or below the landscape water budget established by the CLCA Water Management Performance Program. In addition, the water use may not exceed 100 percent of reference evapotranspiration (ETo). However if a local jurisdiction defines ìon budget or other landscape water consumption requirements that are more demanding than 100 percent of ETo the program will require the local standard. In addition new landscape sites must achieve 80 percent of ETo to qualify.
  2. Expert Certification: CLCA Expert Water Manager. Pass the written test, complete the water audit training and manage five properties for one year and continue to manage five properties at or below the water budget established by the CLCA Water Management Performance Program. In addition, the water use may not exceed 80 percent of ETo. However if a local jurisdiction defines ìon budgetî or other landscape water consumption requirements that are more demanding than 80 percent of ETo the program will require the local standard.
