Contractor Safety Orientation

We are committed to keeping employees, contractors and the public safe while working with the District. Contractors may potentially be required to complete an online safety orientation training that provides a basic overview of the tools and knowledge needed to work safely at CCWD. More information will be provided during contract execution.

Contractor/Consultant Safe Practices Handbook

We require all contractors working at District facilities to read our Contractor/Consultant Safe Practices Handbook (PDF), and sign and submit an acknowledgement form to the District. All contractors' employees must have access to this handbook.
