Sauget (/sɔːˈʒeɪ/ saw-ZHAY) is a village in St. Clair County, Illinois, United States.

[4] Sauget is located in the American Bottom, the floodplain of the Mississippi River opposite St. Louis, Missouri.

It was formed to provide a lighter regulatory environment and low taxes for Monsanto chemical plants at a time when local jurisdictions had most of the responsibility for environmental rules.

[5] The village was incorporated in part in response to the failure of government in adjacent East St. Louis, Illinois to deliver essential services[which?

], and in part to take advantage of federal grant funding programs available only to governmental units, as opposed to private industry.

In addition, the village operates a municipal physical/chemical treatment plant that receives industrial wastewater from its factories.

[5] Located in Sauget is the National Building Arts Center, a historic preservationist and salvage organization which holds one of the largest collections of significant architectural and industrial elements in the US.
