CATCH-BASIN CLEANING

Catch Basin cleaning is the removal of sediment, leaves, contaminants and debris from street-side catch basins to maintain the flow of surface water into the storm system.  Regular maintenance of catch basins and inlets is necessary to ensure they are functioning properly.

Catch basins are storm structures designed to retain sediment by trapping this material in a sump below the invert of the outlet pipe. Catch basins must be cleaned to maintain their ability to trap sediment, and consequently, their ability to prevent flooding. The benefits of catch basin cleaning also include the removal of pollutant loads from the storm sewer system and the reduction of high pollutant concentrations during the "first flush" of a storm event.

Routine cleaning of catch basins reduces the amount of collected sediment and debris which can enter and potentially clog the storm drain network. By preventing the build-up of pollutants in storm water runoff through catch basin cleaning, flooding problems due to the clogging of storm drain networks and the nonpoint source contamination of receiving waters can be greatly reduced.

It is generally recommended to develop and implement a program to evaluate and, if necessary, clean catch basins and other storm water structures that accumulate sediment at least one time per year. Some communities clean once every two years.

It is also recommended that cleaning be done before basins are half full to maintain the sump capacity. Structures that accumulate more debris may need more frequent cleaning. Fall is a good time to clean catch basins after leaves have fallen and before the first snowfall. Another good time to clean catch basins is in the spring to remove the buildup of leaves, dirt, and other debris that accumulated during the winter months. Areas that contribute to higher pollutant loadings or discharge to surface waters should be cleaned more frequently.

Municipalities should insist on the newest, most modern equipment when contracting. With Dejana Industries, you always get the newest technology available. The condition of our equipment is a major reason why Dejana is able to maintain high levels of production without breakdowns.

Catch basin cleaning is often selected for outsourcing because the operation and maintenance of a vacuum truck is a particularly high budget item. Vacuum trucks are expensive to buy and the maintenance required to keep them running is often expensive for a municipality or small company with only a few vacuum trucks. We at Dejana own, operate and maintain a large fleet of vacuum trucks.

Keeping in compliance with the "CLEAN WATER ACT" and ensuring that our lakes, rivers and bays are preserved requires "BEST MANAGEMENT PRACTICES", including scheduled sweeping and catch basin cleaning.
