Maintenance of stormwater basins is essential to ensure the basin controls stormwater runoff and contributes to the reduction of flooding problems. Basins that are not properly maintained will eventually malfunction. When basins fail, very serious hazards can occur, including severe flooding and damage that can be difficult and costly to repair and clean up. In fact, lack of proper operation and maintenance is often cited as the number one reason for failure of stormwater facilities.
