Stormwater Quality
Overview
Stormwater run-off across impermeable surfaces such as roads and parking lots collects pollutants that enter the stormwater management system. Debris, sediment, oils and greases and other pollutants eventually end up in streams, rivers, lakes and other watercourses or are intercepted by treatment plants that have to remove them prior to release.
Various devices are on the market to treat stormwater “at-source” – that is, remove the pollutants where they occur. Emco is proud to offer some of the best-engineered products on the market.
Catch Basin Insert
EnviroStream filter from IPEX is a highly efficient system that drops in to existing or new catch basins. It removes up to 90% of petroleum-based hydrocarbons as well as suspended solids and heavy metals. With flow rates of over 50 USGPM (3.1 L/s), Envirostream can handle the first flush of any storm event.

Grit Interceptor
Over 80% TSS removal and up to12,500 USGPM (700 L/s) treatment capacity – offering a cost-effective solution for primary stormwater treatment.
Oil Water Separator
ecoLine-b from Royal Environmental is an oil water separator that traps liquids with a specific gravity less than 0.95 contributing to an effluent with less than 5 mg/L (5ppm) of residual petroleum contamination. A coalescing media that enhances the accumulation of small oil droplets coupled with an automatic shut-off valve that closes when maximum storage capacity has been reached allows ecoLine-b to be an cost effective BMP. Flow rates up to 320 USGPM (20L/s) may be accommodated and maintenance of the system may be achieved from ground level. To ensure optimal functioning, a grit interceptor may be installed upstream to remove solids and buffer the temperature of the influent allowing the coalescing media to operate unhindered.

Heavy Metal/Hydrocarbon/Nutrient Filter
Removal rates are:
> 80% TSS
> 60% Phosphorous
> 90% Zinc
> 95% Lead
> 90% Copper
* Nitrates (testing results available shortly)
With up to 360 USGPM (22.7 L/s) treatment flow rates, this filter is ideal for environmentally sensitive locations.
