Discharge of Storm Runoff
Discharge of Storm Runoff
(OP)
I'm working on a site inside a Municipality with no storm sewer within a reasonable distance for the scope of work being designed. The existing soil is silt loam with high seasonal water table and slow permeability. I've thought about the idea of treating the runoff and releasing it into a sanitary sewer (this city doesn't accept combined sewer systems).
Does anyone have another idea I could try?

The local agency should really be giving direction to you for this issue.... this also puts some of the responsibility on the municipality for planning development in their jurisdiction to not affect downstream properties and resources.

I understand detention will lessen the immediate impact (in this case the difference between a 10-yr design event and a 5-yr existing conditions events) however these systems are design with overflow components usually designed for a 25-yr or 50-yr event. The existing point of concentration of this site is the shoulder of a turnpike road with no existing ditch or storm sewer within 500 feet. So, I guess an inexpensive solution would be to construct a settling basin outside the existing shoulder for the overflow and constricted (w/orifice) detention flow.
