About S&WB
The Pretreatment Section is responsible for limiting the amount of pollutants from homes, commercial buildings and industrial facilities that are transported via a series of pipes, known as a collection system, to the treatment plant.
Stormwater is water that originates during precipitation events and snow/ice melt. Stormwater can soak into the soil (infiltrate), be held on the surface and evaporate, or runoff and end up in nearby rivers, lakes, or other water bodies (surface water).
Municipal wastewater is water that has been "used" (also called sewage) by a city or parish's residents. It is conveyed in a sanitary sewer system (separate from the stormwater drainage system) to a wastewater treatment plant. Sewage is treated at the wastewater treatment plant and discharged into receiving water.
