A sediment basin is a temporary pond built on a construction site to capture eroded or disturbed soil that is washed off during rain storms, and protect the water quality of a nearby stream, river, lake, or bay.

Sediment basins in large drainage areas can capture sediment from stormwater before it leaves a construction site. A sediment basin allows a pool to form in an excavated or natural depression, …

A sedimentation basin (SB) is defined as a structure that separates solids from water through gravity settling, primarily used in wastewater treatment processes to effectively remove suspended solids.

What Are Sedimentation Basins? Sedimentation basins (also called sediment ponds or settling basins) are engineered impoundments that slow stormwater so suspended soil particles can settle before …

Sediment basins provide the last line of defense for capturing sediment when erosion has already occurred. When possible construct the basin prior to soil disturbance in the watershed.

This type of basin conserves land area, but has higher operation and maintenance costs than a one-level rectangular basin. Square or circular sedimentation basins with horizontal flow are often known …

Jul 7, 2025 · A well-designed sediment basin consists of four main parts: an inflow channel, a settling pond with porous baffles, a dewatering device and an auxiliary spillway.

The primary purpose of sediment basins is to prevent sediment from entering streams, rivers, lakes, or wetlands. They do this by collecting and detaining runoff, allowing suspended solids to settle out …

Although no one basin classification scheme has been widely adopted, several common types of sedimentary basins are widely accepted and well understood as distinct types.

Sediment basins are strategically-located, deepened, below-water trenches or pits. The sedimentation basins create a low-energy zone where (fine) sediments can settle and deposit.
