The PaveDrain System is a Permeable Articulating Concrete Block (P-ACB)  that creates a performance pavement that integrates the patented arched  reservoir to maximize on site stormwater capacity. 

The open jointed system improves the  typical storm hydrograph and  increases environmental performance while reducing stormwater infrastructure costs. The PaveDrain system can be designed in a variety of configurations customized for specific applications and installed very quickly with conventional construction  equipment. 

The PaveDrain System allows for a more natural (vertical) infiltration path, recharging local groundwater and reducing first flush pollutants. By reducing a typical storm hydrograph while also filtering out suspended sediments this combination of Best Management Practices (BMP's) illustrate stellar life-cycle cost savings, clearly making the PaveDrain System a superior choice for effective stormwater management. 

The Clean Water Act 

As part of the Clean Water Act, the U.S.  EPA developed the National Pollution  Discharge Elimination System  (NPDES) to improve water quality by  regulating point source pollution that  discharges into water of the U.S. The  vast majority of storm water drainage  systems are considered to be point  sources.
