The need for stormwater detention and filtration has grown exponentially since 1970. Stormwater systems were previously required to detain runoff for ten to one hundred year storms. Increased government regulations now focus on nutrient monitoring and the removal of silt and nutrients from runoff systems.
Stormwater runoff occurs when precipitation from rain or snow flows and cannot soak into the ground due to impermeable surfaces such as driveways, parking lots, roof tops and roadways. This means that many pollutants including sediment, nitrogen, phosphorous, oils, pesticides, metals and silt are carried into local streams, rivers and wetlands. The more urban the area, the more intensely polluted runoff is prevalent. The heightened awareness of this contamination issue and the ensuing regulations has resulted in the creation of many new stormwater filtration products. These systems can vary in size and material depending on the environmental requirements and the nature of the jobsite.
Since 1992 Colonial Construction Materials has brought the most innovative stormwater products to the market. From chamber systems for detention with filtration to inlet filters that remove high levels of minerals and pollutants, Colonial will design and provide the most efficient and cost-effective detention and filtration systems.
Detention and filtration systems can vary in size and material. Below are just a few options that are available at Colonial:
- Corrugated metal sand filters
- Concrete storage chambers
- Chamber systems
- Inlet filters
- Organic dry BMPs
