DWSD Procurement

The awarding of Detroit Water and Sewerage Department (DWSD) contracts are based, in part, upon requests for proposals (RFPs) and the open competitive bidding process.


Here's how to proactively prepare to respond to our solicitations:

Register with Michigan Inter-Governmental Trade Network (MITN) hosted by bidnet direct

Signup Button

This is where we publish our solicitations (Request for B = Bid, Q = Quote, I = Information, P = Proposal) MITN does have two options - a free version where a contractor needs to watch for bids, or a paid version which will notify you of all new solicitations that fall under the NIGP codes that you chose during registration. (NIGP code is a universal taxonomy for identifying commodities and services in procurement systems). Visit www.mitn.info to sign up.
