How does the pretreatment program work?
Generally, industrial dischargers to the sanitary sewer system (including restaurants and food preparation facilities) must receive a permit from the City.

"Permitted" facilities are required to have tests run on their wastewater by independent labs at stated intervals and must report the results of the tests to the City.

The City of Shreveport Pretreatment staff visits the permitted businesses without warning from time to time to sample the wastewater being discharged. These samples are also tested to make sure the permit is not being violated.

The City's Pretreatment Staff is responsible for reporting monitoring results regularly to the Louisiana Department of Environmental Quality.
