SWMM - Water Quality

Data related to water quality is provided to a SWMM model using the following types of objects:

• Pollutants - The accumulation and leaching of pollutants from the sub-Catchment areas are determined by the land uses assigned to these areas
• Land Uses - Land uses are categories of development activities or land surface features assigned to Subcatchments
• Treatment - The removal of pollutants from inflows at any node in the drainage system is modeled by assigning a set of treatment functions to the node
