Multi-cell Dry Sediment Basin

The Multi-Cell Dry Sediment Basin trap uses a special design of weirs , placed at a variety of strategic positions and angles, to guide the flow through a predetermined path. This action reduces the velocity of the flow and allows the sediment to drop and settle into the containment cells. We don't try to stop the flow, nut rather use it to transport the sediment to where we want it to go. This is the basis of our catch phrase 

 


Where Used

The Multi-Cell Dry Sediment Basin is used in medium to high velocity sites where there is minimal headloss (depth to invert) available. 

 


Site Requirements

Target Pollutant Class

The Multi-Cell Dry Sediment Basin is targeting the capture of Sediment pollution class. 

Water Sources \ Velocity

The Multi-Cell Dry Sediment Basin is primarily used for sites with low to high velocity flows. The Multi-Cell Dry Sediment Basin is suitable for treating the following water sources:

  • Pipes
  • Culverts

Grades

The Multi-Cell Dry Sediment Basin is suitable for grades from less than 0.05%  to to any grade. Please note while we can cater for high grades some design modification may be required.

Treatable Flow

The Multi-Cell Dry Sediment Basin is suitable for treating flows from as low as a 3 month ARI to a 100 year ARI.

We don't treat the "first flush", we treat the whole flow for the duration of the event.


Configuration

Size

The size of the Multi-Cell Dry Sediment Basin is dependent on the:

  • Cross Sectional area of the Water Source, 
  • Velocity, 
  • Grade,
  • Treatable Flow 

T o give you an idea of sizing here is a sample set of configurations.

Note: These figures are indicative only and do not represent the largest or smallest sizes we can treat. If you need an estimate size for your plans please contact us and we will be able to provide this information to you over the phone if you can provide some or all of the Site Requirements.

Lidded

The Multi-Cell Dry Sediment Basin is suitable as a lidded or open solution.

Pollutant Storage

The Multi-Cell Dry Sediment Basin uses online storage.

Trap Access

The Multi-Cell Dry Sediment Basin can be accessed by internal rungs.

 


Installation

Standard equipment and modular construction combine to make installation convenient with minimum interruption or alteration to existing conditions. Deep excavation is not a required with the Multi-Cell Dry Sediment Basin.

 


Cleaning

Cleaning of the Multi-Cell Dry Sediment Basin is carried out manually.
