Filterra® Bioretention image

Filterra® Bioretention

Filterra is similar to bioretention in its function and application, but has been optimized for high volume/flow treatment and high pollutant removal. Its small footprint allows it to be used on highly developed sites such as landscaped areas, parking lots and streetscapes. Filterra is exceedingly adaptable and can be used alone or in combination with other BMPs.

At every stage of your project, count on Contech to provide engineering services including: Regulatory guidance and permitting assistance Preliminary standard details and/or site specific final CAD drawings and specifications Low Impact Development design assistance Engineering calculations for hydraulics/hydrology, rainwater harvesting, and detention/retention Review of preliminary site design, feasibility screening, and layout assistance Value Engineering - cost estimates and options analysis Pre-construction support, project scheduling, and contractor coordination Installation and construction support Maintenance support The result - an efficient design process, the right product, more land space savings, and faster permitting.
StormFilter® Stormwater Treatment image

StormFilter® Stormwater Treatment

The StormFilter stormwater treatment system uses rechargeable, self-cleaning, media-filled cartridges to absorb and retain the most challenging pollutants from stormwater runoff including total suspended solids, hydrocarbons, nutrients, metals, and other common pollutants. StormFilter performance has been verified by the State of Washington Department of Ecology and New Jersey Department of Environmental Protection, as well as numerous other stormwater regulatory agencies.
ChamberMaxx® Stormwater Chamber System image

ChamberMaxx® Stormwater Chamber System

The ChamberMaxx corrugated, open-bottom plastic infiltration chamber system allows you to meet stormwater runoff reduction requirements and maximize available land space by providing economic infiltration below grade. ChamberMaxx maximizes storage volume in a small footprint, and its low profile shape is ideal for sites with shallow footprints.

Stormwater Treatment

Removing pollutants from stormwater runoff is an important component of any stormwater management plan. Stormwater pollution - sediment, trash and debris, nutrients, and metals - is one of the leading causes of water quality impairment we are facing today. There are numerous technologies available for treating runoff - and the right system for your site should be selected based on your local requirements, your target pollutant, and specific site characteristics. As no two projects are the same, there is no one size fits all answer. Our treatment projects are flexible and customizable - and are effective as either conventional end-of-pipe BMPs (best management practice) or small-scale decentralized IMPs (integrated management practices) in a low impact development (LID) design. Filters can help you remove the most challenging pollutants from stormwater, including nutrients like phosphorus. There are many variables to consider when designing a stormwater filtration system. It's critical to use a balanced approach that incorporates hydraulics, longevity, and performance. Hydrodynamic separators were the initial underground water quality devices developed 20 years ago. We've been there since the beginning - and our systems are widely accepted for effective solids removal. Especially efficient on gross solids, trash and debris, they are an optimal choice for pretreatment systems.
