In just three years, private contracting company, Atlantic Pipe Services (APS), turned its two-person team to a staff of 64. President of the company, Allan Cagle, says that growth and success can be attributed to two things: investing in high-performance equipment and a crew selectively hired to align with their vision.

When it comes to manhole and sewer inspection, it’s about more than just the numbers. To conduct the most thorough analysis, use a combination of quantitative and qualitative data.

Many wastewater system managers focus on pipelines. But manholes can be an even greater source of problems, insome extreme cases contributing up to 90% of inflow and infiltrationin a system. And as they’re easier to access, manholes are generally less expensive to fix. To repair them though, they must be inspected.

Thank you to the many customers and partners who visited our booth during WEFTEC 2018 in New Orleans last week. We welcomed nearly 300 guests and enjoyed seeing many of our sales partners from across the country. A special thanks to Best Equipment, our sales partner in Indiana, Ohio and Kentucky, for loaning us their new demo truck for the show.

Manholes are a critical part of every sewer system as they provide necessary ventilation and an access point for cleaning and inspecting sewer lines. The EPA estimates that there are about twenty million manholes in the United States—one manhole for every 400 feet of pavement. Many of these manholes are seriously decayed or in need of immediate rehabilitation or replacement. Manholes generate a disproportionate amount ofinflow and infiltration (I&我)and play a unique role in the structural integrity of roadways. From an operational standpoint, inflow and infiltration of groundwater reduces capacity of the collection system as a whole. From a structural standpoint, deterioration and corrosion within a manhole can cause cave-ins (Water World).
