The control of odorous gases and the corrosion of sewers are the two most important problems in operating wastewater collection systems.  H 2 S is the most commonly known and prevalent odorous gas associated with domestic wastewater collection and treatment systems.  InfoSewer. InfoSWMM, H 2 OMap SWMM or H 2 OMAP Sewer suite gives wastewater engineers a powerful Operations and Maintenance (O&M) tool to readily model and analyze entire sewer collection systems for sulfide generation and corrosion potential under varying conditions anticipated throughout the life of their systems. H 2 S  predicts sulfide buildup in sewer collection systems for gravity sewers, force mains, and wet wells using the Pomeroy-Parkhurst equations. This unique and powerful tool enables wastewater utilities to pinpoint odor and corrosion problems, develop effective monitoring programs, alert plant operators and sewer maintenance workers to potential danger and the need to observe safety practice...

This is for students of SWMM 5 who want to quickly have many water quality constituents in their model.  You can copy and paste this snippet to your SWMM5.INP file and change the coverages sections to have 25 Pollutants with Buildup and Washoff Sections.  I hope this helps you in your water quality modeling.
