CLCA Increases Efforts In Water Efficiency By Offering Two Nationally Recognized Industry Certifications With One Course and One Written Test

The California Landscape Contractors Association and Metropolitan Water District of Southern California now offer a one-of-a-kind certification and educational opportunity for landscape professionals in Southern California.

This joint effort combines the CLCA Water Management Certification Program with the Qualified Water Efficient Landscaper program to offer the landscape industry an opportunity to obtain two nationally recognized EPA WaterSense Professional Certifications with one course and one written test.

Presented virtually in six three-hour classes, these workshops will offer CEUs for your current certifications and provide you with a participation certificate. These workshops are free and available only to those in select counties of Southern California within the Metropolitan Water District’s service area.

The combined curriculum focuses on landscaping fundamentals in one convenient course and includes topics like:

  • Where Our Water Comes From
  • Sustainable Landscaping
  • Landscape Water
  • Soils
  • Irrigation Systems
  • Irrigation Maintenance & Trouble Shooting
  • Irrigation System Auditing
  • Irrigation Scheduling
  • Irrigation Controllers
  • Landscape Water Management
  • Landscape Water Budgeting
