I live in a Townhouse in NC, in a community under a HOA management. I've been doing some improvements on my patio. One of them that I couldn't find a solution is what to do with the condensed water from the AC draining. My AC is installed in the attic. 2 drain lines come from it. One is the main one which ends on my patio , the other line has an end on the soffit area of my roof (The secondary / auxiliary line coming from the dripping pan in the attic). The main line, specially in summers where I use AC a lot, creates a soggy area on my lawn, so wet that even the guys from the HOA landscape company have had hard time trying to mow there.
Since I live in a Townhouse, and no way to redirect the water beyond my property line, I've read several workarounds to solve this problem:
Some suggests to connect indirectly to sewer system like this post: Connecting condensate pump to sewer
Other suggests a mini drain well with gravel: How do I eliminate stagnant water caused by central A/C draining outside?
In my Case, I would like that mini drain well option, however, my concerning is the heavy clay soil I have. After just a few inches of topsoil, I see underneath just pure Clay. I guess that's the reason why water is ponding and creating that soggy area (see pic), specially in summers. If I create that dry well with gravel, what are the chances that the rate of water absorption of the clay underneath and around the dry well underground will be faster than the rate of water saturation of the dry well itself (being continuously and daily watered by the AC condensation line) before starting to pond water around again? I've read that a 2 Tons AC can create between 10 - 20 gallons of condensed water per day in summers. Is there a minimum size and depth for this dry well on a heavy clay soil to be effective, or is this solution not worth it on a clay soil?
