We size dry wells to the roof area or drain feeding them, not a one size guess.
Placement keeps each well clear of the house, the lot line, and any leach field.
Overflow outlets keep extreme storms from backing water up toward the house.
Well size, pipe length, and site access set the price. A single well for one downspout is a modest project, while larger systems serving several downspouts or a French drain take more digging.
Sending water to the curb is usually simpler when the lot slopes that way. A dry well earns its keep when the street sits higher than the backyard or the pipe run would be long and awkward.
A well has to hold a heavy storm’s worth of water while it soaks in. Undersized wells fill up and back up.
On larger lots near Latigo and Eastonville Road, we keep dry wells well clear of septic tanks and leach fields.
Dry wells often collect from French drains and buried downspout lines. See our Peyton irrigation and drainage page.
We measure the roof or drain feeding the well and check how the soil drains.
Crews dig the pit, install the chamber or gravel, and run solid pipe from the downspout or drain.
An overflow is added, the surface is restored, and we test the system with water.
