The maximum flows shown are usually the 10-year or 25-year flows taken from the pipe system design chart. Water Quality flows are typically 20 to 30% of this flow. Our designs analyze and can accept the largest expected storm flows, but center their efficiency around the water quality storms. Your local regulations may allow slightly higher than maximum flows, or may require slightly lower flow limits.
