Water Quality Modeling
Excerpt from the EPA manual Storm Water Management Model Reference Manual Volume III – Water Quality (PDF) which can be found here
Management of stormwater quality is usually performed through a combination of so-called “best management practices” (BMPs) and a form … Read the rest
| Water Quality Modeling Features |
In addition to modeling the generation and transport of runoff flows, SWMM can also estimate the production of pollutant loads associated with this runoff. The following processes can be modeled for any number of user-defined water quality constituents:
| · | dry-weather pollutant buildup |
The Water Quality Simulation Parameters govern how the engine performs the additional water quality calculations during a simulation.
It is not normally necessary to amend the Water Quality Simulation Parameters. The default values have been chosen for optimum accuracy and performance. However, these parameters can … Read the rest

The control of odorous gases and the corrosion of sewers are the two most important problems in operating wastewater collection systems. Evaluation of existing or potential odor or corrosion problems, and identification of where such problems will occur is, therefore, highly essential. … Read the rest
Modeling H2S in InfoSWMM
You can model Sulfide in InfoSWMM using the H2S water quality modeling option which uses BOD5 loading at nodes to estimate the S concentration in the nodes and links of the network using constant network parameters for:

This blog is a companion to the blog post https://swmm5.org/2017/04/17/swmm5-simple-100-mm-rainfall-model-for-lid-modeling-part-1/ in which a 1 Hectare model with 100 mm of rainfall had a simple Bio-Retention Cell with no LID outflows. In part 2 of this blog series we will add a drain coefficient of 10 mm/hr (Figure 1). The internal … Read the rest
Simple SI Unit Model for SWMM5 LID with 100 mm Rainfall.
Reading this blog and using the embedded SWMM 5 example file, you will run a simple SI unit model based on factors of 1 and 10.

The purpose of the quality model is to simulate pollutant loading and buildup, washoff, as well as individual domestic, commercial and industrial contributions, and transport. Seven different types of quality analyses can be carried out by InfoSewer/Pro and are explained below.
POLLUTANT TRANSPORT
InfoSewer/Pro can effectively simulate the … Read the rest
