Find Sources of Inflow Fast!

Smoke Testing is the most cost effective method to find sources of surface water inflow - the leading cause of wet weather SSO’s. Fast and easy to do, Smoke Testing produces immediate results that can be acted on quickly - often at minimal expense to the Municipality.

Common sources of sewer inflow include:

  • Roof Downspouts
  • Abandoned Sewer Lines
  • Cross Connected Storm Lines
  • Cross Connected Sanitary Lines
  • Yard / Foundation Drains
  • Unconnected Sewer Lines
  • Leaking Manholes
  • Broken Laterals
  • Cellar Drains
  • Sump Pumps

Hundreds of millions of feet of sanitary sewer mains have been effectively tested using Superior® Smoke products, eliminating countless faults - and the SSO’s that would result from them.
