Problem: While performing the rehabilitation of sewer manholes in Baltimore County, Maryland, MIDAS Companies had difficulty controlling the flow while working on the manhole bench and channel.
Solution: MIDAS consulted with Logiball to see if they had a large flow-through plug that could provide an easier way to control the existing flow in order to allow a more efficient rehabilitation of the manhole bench and channels. Logiball proposed its Type “D” Flow-Thru Plugs. The double- action bladder allows for the inward bladder to seal against the pump suction hose or bypass pipe while the outer bladder seals against the host pipe wall.
Result: Use of the plugs allowed for a quicker and safer diversion of flow during the rehabilitation process.
