Requirements of regulated MS4s under the NPDES Stormwater Program
Regulated entities must obtain coverage under an NPDES stormwater permit and implement stormwater pollution prevention plans (SWPPPs) or stormwater management programs (both using best management practices (BMPs)) that effectively reduce or prevent the discharge of pollutants into receiving waters.

The Inceptor is suited for municipal applications and offers benefits when included in SWPPPs as a BMP.


These benefits that provide better operating margins include:
· Manufactured for retrofit applications
· Low maintenance frequency Filter replacement only
· Easy installation requires no tools
· Guaranteed unit construction
· Ability to treat small to significant flow rates
· Built in bypass on all units
· Filter disposal is non-hazardous solid waste
