Overview

Although quite rare thanks to the vast improvement in CCTV inspection technology over recent years, there are still inspection situations where the traverse of a large sewer or tunnel remains the only suitable option to gain useful data on the condition of the structure. There are times when there is no substitute for touching and probing a structure to help to assess its structural integrity…that's when our clients call upon our specialist sewer traverse teams.

Confined Space Entry regulations quite clearly state that persons shall not be put at risk by entering a confined space where a safer alternative exists. In the case of very large sewers and tunnels or where access points are a great distance apart, inspection by CCTV methods just isn't an option and the only alternative (assuming not undertaking the inspection isn't an option) is to introduce a traverse team into the sewer to carry out the survey.

Because of the inherent dangers involved in this process, the teams are hand picked due to their extensive experience in traversing sewers…this is not an environment for the faint of heart!

Strict operational procedures are followed, backed by job specific Method Statements and Risk Assessments. If it is deemed that a separate Emergency Rescue capability is required, OnSite use the best guys in the business - Mines Rescue, who in our opinion provide a rescue service which is second to none.
