Vendor Registration

All District vendors are required to Register and submit a Vendor Application on the District's website. By registering in the District's Vendor Registration system, your organization will receive procurement / notices via email.

To assist vendors with the new registration process, the District has posted a user guide, How to Create an Account and Register with the District.

Even when registered, vendors are responsible for checking the website and downloading applicable Bids, RFP's, RFQ's, and addendums.

If you are an individual and not a vendor but wish to be notified of all procurement notices, please email the procurement department with your contact information, full name, address, phone, and email address and you will be added to the vendor notice database.

To continue with vendor registration, please select one option below. If you require technical assistance while completing the application, please use our online support form.
