What does DICB mean in UNCLASSIFIED

A Ditch Inlet Catch Basin (DICB) is a type of stormwater pumping system used to capture and divert water runoff from impervious surfaces such as parking lots. It helps reduce runoff velocity and sediment transport to downstream channels before the water enters the drainage system.

A DICB works by collecting, filtering, and storing runoff before it enters the drainage system. It reduces runoff velocity by slowing down water flow as it passes through its design elements such as baffles or other structures that induce turbulence or decrease flow rate. Sediment transport is also reduced since large particles are trapped in the basin while smaller particles pass through perforations in the outlet pipes into an underground storage chamber or tank until they can be removed safely over time.

A DICB is necessary to help reduce pollutants from entering local waterways due to their ability to temporarily store sediment and pollutants until they can be removed safely. By capturing these materials before they enter the drainage system and diverting them away from populated areas, a DICB helps protect aquatic life, recreational uses of waterways, drinking water supplies, and more.

A DICB can be installed at any location where there are impervious surfaces that generate surface runoff like parking lots or roads with concrete curbs or gutters but they must be located downstream of potential sources of pollution so they can act as collection points prior to discharge into waters that supply drinking water sources or aquifers used for irrigation purposes.

Maintenance requirements vary based on factors like climate and frequency of rainfall but generally speaking it's important to inspect your DICBs regularly for damage, clogs, vegetation growth around edges etc., perform regular cleaning with vacuum trucks if needed, repair eroded areas around walls etc., check inlets for obstructions etc., empty accumulated sediment periodically etc., depending on what's applicable at your particular site.
