  Diameters of force mains transporting sewage have a significant impact on the amount of hydrogen sulfide generated because of three reasons: the detention time of wastewater in the main, the biofilm surface area, and the thickness of this biofilm.This impact is discussed here using wastewater parameters from an existing system,renovated after a breaking down, caused by extremely fast sulfide corrosion attack.
