Manhole Inflow Protector
The Plastic Manhole Inflow Protector Inserts are made of high density polyethylene and have been proven effective in reducing or preventing surface water inflow to the collection system, through the manhole lid. Operating and maintenance costs for plant equipment and pumps are minimized due to reduced flow during heavy rainfall. Also, utility costs are reduced because machinery is not operating for extended periods of time. These inserts are a practical solution to expensive plant expansions, and new construction.
