Services to extend operational life of

existing sewer systems and infrastructure


SeweX is an advanced mathematical modelling tool describing the physical, chemical and biological processes in sewers.


The model can:

  • Provide spatial and temporal liquid sulfide profiles for any given pipe or network of pipes.
  • Predict sulfide profiles under control conditions where chemicals are dosed to control the formation of sulfide, such as oxygen injection, pH change using magnesium hydroxide or lime, and nitrate or iron salt addition.
  • Provide optimal dosing rates and locations for existing or planned chemical dosing stations.

This powerful modelling capability is a 'must have' for water utilities and consultants focused on providing precise sulfide predictions in sewer networks, and optimal solutions for sulfide control.
