Sediment screening for dry wells
Sediment screening for dry wells
(OP)
I have an asphalt paved area graded to a drywell for storm water infiltration. What are you folks doing to screen out sediments, leaves, and similar debris so the gravel doesn't get filled in with fines? Are you folks even worried about that? Low maintenance suggestions preferred.

Side question, are you folks completely filling your drywell with rock/stone/gravel, or just the bottom foot or so?

Dry, windy, sandy, open area. Ten year 1-hr design storm is 2.25".
I'm leaning towards doing nothing special to screen sediment, just letting the drywell fill. If it's filled with stone, they'll have to clean it every 8 years. If I only put stone in the bottom 2 feet, it might have to be cleaned in 25 years. Obviously the latter is cheaper and faster. I've just never designed one that way. If there's a reason for that I can't remember. That's why I was wondering if anyone's done it with stone only at the bottom.
