About Sewer Knowledge Services

Sewer Knowledge Services LLC was founded on a simple idea: that the sewer infrastructure industry deserves better training, more accurate data, and smarter implementation of the tools available to it.

Eric Sullivan, Principal, has spent 19 years working across every facet of sewer condition assessment — from hands-on field work to project consulting, NASSCO-certified training, and direct involvement in the development and deployment of advanced sewer inspection technology. That breadth of experience is what sets us apart.

We work with municipalities, engineering firms, and contractors across the US and Canada, providing services that are practical, accurate, and grounded in real field experience. 

We don’t believe in one-size-fits-all solutions — every client has different infrastructure, different teams, and different goals. Our job is to understand yours and help you move forward with confidence.
