Temporary Sediment Basin Solutions & Installation

A sediment basin is used to capture stormwater runoff from disturbed construction areas and allow suspended soil particles to settle before water is discharged. It helps reduce sediment leaving the site, protects downstream drainage systems, and supports erosion and sediment control requirements. Basins are commonly used on roadway, site development, municipal, and infrastructure projects with significant exposed soil.

A temporary sediment basin or trap is designed to slow runoff, hold sediment-laden water, and separate soil particles before discharge. It is typically used during construction while soil is exposed and permanent stabilization is not yet complete. Supporting products such as dewatering bags, filtration tanks, inlet protection, erosion blankets, and flocculants can improve performance depending on site conditions.

A sediment trap is generally smaller and used for localized drainage areas or shorter-term control, while a sediment basin is larger and designed to manage runoff from broader disturbed areas. Basins usually require more planning, storage capacity, outlet control, and maintenance. The right choice depends on drainage area, expected runoff volume, soil type, construction schedule, and project compliance needs.

Sediment basin sizing is typically based on disturbed drainage area, runoff volume, soil conditions, slope, rainfall expectations, and discharge requirements. Engineers or project specifications may define the required storage and outlet design. Coleman Moore Company can help review site needs and recommend supporting products such as filtration tanks, dewatering bags, flocculants, and erosion control measures.

Yes. Temporary sediment basins often work alongside dewatering systems when water must be pumped from excavations, low areas, or active work zones. Dewatering bags, portable filtration tanks, and flocculants can help remove sediment from pumped flows before discharge. The best setup depends on turbidity levels, pumping rates, available space, and the required water quality outcome.

Supporting products may include erosion control blankets, turf reinforcement mats, sediment logs, rock bags, turbidity curtains, inlet protection, dewatering bags, filtration tanks, and flocculants. These materials help control runoff, protect slopes, treat discharge, and prevent sediment from reaching storm sewers or waterways. Product selection should be based on site layout, soil conditions, and project requirements.

Temporary sediment basins should be inspected regularly, especially after rain events, pumping activity, or major site changes. Maintenance may include removing accumulated sediment, checking embankments, clearing outlets, replacing damaged controls, and confirming water is flowing as intended. Consistent maintenance helps preserve storage capacity, reduce compliance issues, and keep the basin functioning throughout construction.

Coleman Moore Company provides strategic site evaluations, product analysis, cost-benefit guidance, design assistance, and installation consultation for erosion and sediment control projects. The company helps contractors, engineers, municipalities, and developers select practical products and understand proper field use. Support is focused on matching materials and methods to project goals, site conditions, and budget constraints.
