Midwest Municipal Supply is a family owned business founded in 1989. Our new state of the art facility is located in Caseyville, IL. We distribute a complete line of water, sanitary sewer,  storm drain, and fire protection products to contractors and municipalities in the St. Louis metro area.

We are the largest single store or branch in the area, featuring a delivery  fleet of 7 trucks and an inventory  of over $2 million.  Yet we are still small enough to remain flexible. Orders can be changed, trucks can be re-routed, decisions are made in real time. Our owner and management are here every day.

Our goal is to save you time and money. We make sure the order is right the first time. Our large inventory enables us to limit backorders. Our hands on approach helps make sure you get only the products you need. We work with you from taking off the plans to ordering to delivery. And there is service after the sale. You can call anytime to tap our reservoir of knowledge.
