Overview

The RWM OGS (Rainwater Management Oil/Grit Separator) unit is an important and effective total pollutant treatment component of your stormwater management program and is approved in every major jurisdiction in Alberta.

The RWM OGS unit features a non-blocking, indirect screening technique to treat stormwater runoff. The unit is highly effective in the capture of suspended solids (fine sands and larger particles), hydrocarbons, and unmatched in any floatable trash larger than 2.4mm. This unit is a non-mechanical self-operating system and will function any time there is flow in the stormwater drainage system. The unit will continue to effectively capture pollutants in flows up to the design capacity even during extreme rainfall events when the design capacity may be exceeded. Pollutants captured in the unit’s separation chamber and sump will be retained even when the units design capacity is exceeded.

The RWM OGS units do not require a drop from the inlet and outlet (low head requirement and inlet pipe settling), can accommodate multiple inlets at almost any angle and top inlets, and are highly customizable for almost any application and sediment load requirement.
