It's just 4"s. No time frame. That dictates the size or volume of the drywell.
So, in other words, if you had a 1,000 sq ft patio then you would need a drywell of at least 334 sq ft. which would be one 4' tall x 8' diameter precast drywell.
Its obviously less if you were taking the runoff from an area other then a roof or paved surface.
