What is better than a dry well?
A french drain is a popular alternative to a drywell and a better choice for surface drains in some cases. French drains can route standing water towards a storm drain, a pond, river or another ideal drainage area.
Why do dry wells fail?
Dry wells can be susceptible to clogs coming from sediment, debris, and other blockages that come with runoff, which makes the dry well useless. As wastewater seeps out of the bottom of the pit any solids that do not dissolve will settle to the bottom, too, which prevents draining.
Do dry wells freeze in winter?
Dry wells give downspout water a place to go if existing grading does not allow for water run off or if there are hard scape issues. [patios, driveways, walk ways] If installed correctly they will also work in freezing temperatures.
What happens when dry well is full?
Once it reaches it full capacity, water begins to spill out over the side of the cup. The same thing happens to your gutters. Another bad thing about drywells is that if leaves or any other debris gets into the line, the stone becomes clogged easily. Leaves fall into your gutters and then wash down into the drywell.
