We use high-resolution cameras that capture 360° views, allowing operators to conduct real-time assessments in the field. The resulting videos are then analyzed in-depth at our headquarters, providing a reliable basis for engineering decisions. Our comprehensive imaging and assessment methods give stakeholders a clear understanding of the sewer system's condition.

CES is committed to delivering high-quality inspections led by trained experts. We perform inspections for both sanitary sewers and storm drains, adhering to NASSCO standards or through a customizable, GIS-based platform.

Accurate inspection data is essential not only for condition assessments but also for flow modeling and system optimization. During an inspection, our crews may document more than 100 specific points of data, ensuring a detailed and thorough evaluation. These assessments consider maintenance issues, structural integrity, flow performance, and inflow and infiltration (I&I) to give a complete picture of the manhole's status.

frequently asked questions

Are manhole inspections considered high priority?

In any Sewer System Evaluation Survey (SSES), manholes play a key role and should be prioritized. According to an Environmental Protection Agency (EPA) research paper, “30 to 50 percent of inflow and infiltration is due to defects and conditions in or near manholes.” 

Early identification of these problems through thorough inspections helps prevent hazardous situations and expensive repairs. By integrating manhole inspections with GPS data, CES can determine a precise inventory of the system's manholes.
