Cal Water seeks to cultivate business partnerships with qualified suppliers that can provide goods and services at competitive prices and that add value to the service we provide our customers.
Our purchasing needs span every area of our business—from construction, maintenance equipment, and tools to office supplies and business services—and we are committed to cultivating relationships with suppliers who can help us provide the best value and service to customers. See our Supplier Diversity Annual Report for more information.
Our sourcing opportunities go through a formal, competitive request for proposal (RFP) and bid process. After you are registered in our database, we will contact you when we have an opportunity that relates to your submission.
