The Challenge
The intake for the temporary bypass system needed to be done from the pipe itself as a new manhole was being installed to allow for increased capacity. As originally installed, the pipe was far below the maximum suction lift capability for the pumps required and a bench needed to be excavated for the pumps to operate within range.
Our Solution
- Stormtec worked with the client to advise the optimum benching requirement needed
- An innovative isolation technique was installed to create an acceptable wet well to pump from
- Crews initiated a site-specific safety measure in response to the unique conditions relating to the placement of pumping equipment
