Note: Site descriptions can help us lower your treatment flow rates. The lower your percentage of impervious, the lower your water quality flow requirement will be in most areas. A sketch with some pipe slope information can let us set an invert in, if you are not sure of that parameter. Invert out of our device will normally be 0.10 or 0.20 feet below the invert in. We can make this drop less if your pipe slopes are less than 1%.

Jurisdiction Information

Calculated Maximum Flow in Pipe
cfs in year storm
Water Quality Rule
Water Quality Flow (if specified)
Governing Jurisdiction (city/county, state)

Note: Maximum flow is from your pipe chart, such as "25-year peak flow is 10.3 cfs." We will research the exact water quality flow standard for your jurisdiction and state if a "generic" specification such as "1-inch first flush" depth standard is utilized.

Any important information you can add, such as details on receiving waters, etc., will help us provide you with a more powerful presentation to your local jurisdiction.
