Get Started

If you are interested in doing business with DC Water, the Vendor Portal is your first stop. DC Water upgraded our vendor portal to the Zycus Supplier Network (ZSN). Even if your company is registered in the current vendor portal, you must register in ZSN.

ZSN will be the single point of doing business with DC Water. Only the companies who are registered in ZSN will be able to view and participate in new solicitations.

Procurement will continue to post all open solicitations in the old portal. New solicitations issued through ZSN will be posted on both portals (old and new) until all open solicitations have been issued using the new eProcurement software. At that time, the old portal will be de-activated.

Regardless of how recent your company registered, you must re-register in the ZSN. Your company’s current information in the old vendor portal will not be transferred.

Click on the “Guide to New Vendor Portal” to get started. Then click on the “New Vendor Portal (ZSN)” to start your registration process. In addition, DC Water has updated the category listings in ZSN. We encourage you to review your company's profile and update your category listing for all seven category selections.
