As a result of working with stormwater management companies and their designs, CPF has manufactured hydrodynamic devices for stormwater detention, such as a groundwater barrier and a hydrodynamic separator. A groundwater barrier prevents contaminants from entering the environment and groundwater sources. The primary purpose of a hydrodynamic separator is to remove sediments and pollutants. Hydrodynamic separators are flow-through structures that include a sediment settling or separation unit. For treating and pretreating stormwater runoff, hydrodynamic separators are an effective best management practice (BMP).  

In addition to stormwater management system components, CPF offers custom stormwater and rainwater collection tanks. These custom tanks can be above or below ground. Tank sizes range from 500 – to 10,000 gallons. Modular designs are available for tanks greater than 10,000 gallons.  As rainwater management regulations become more prevalent in the United States, CPF can be part of an engineered solution to your project.

A stormwater management system’s primary function is to retain stormwater and remove pollutants before discharging water to the environment. Stormwater systems manage runoff from rainfall or snowfall. As our world became more advanced with roads and parking lots, and other impervious surfaces, it became difficult to allow for natural stormwater runoff. Manufactured stormwater systems mimic biological processes and come in various shapes, sizes, and configurations. 

According to the United States Environmental Protection Agency (EPA), stormwater management is the effort to reduce rainwater or melted snow runoff into streets, lawns, and other sites, improving domestic water quality. 

When stormwater soaks into the soil, it is filtered and flows into streams, rivers, lakes, and wetlands. However, the wet ground from heavy rain, creates excess water that runs into storm sewers and road ditches. This water often carries debris and pollutants. 

Pavement and roofs prevent precipitation from naturally penetrating the ground in developed areas. Water instead runs rapidly into storm drains, sewer systems, and drainage ditches, resulting in: 

• Overflow to storm and sewer systems 
• Damage to infrastructure 
• Flooding downstream  
• Destruction to habitats 

• Erosion of stream banks 
• Stirred up sediment 
• Streams, rivers, lakes, wetlands, and coastal water contamination 

Surface water runoff, or stormwater, and any sewer inflow, or sewer infiltration, becomes part of a municipal wastewater process.  To read more about CPF’s wastewater products click here.
