The right solution for draining areas in yards prone to flooding, the Flo-Well® Dry Well System is installed underground to collect, temporarily store, and slowly release excess water into the ground. Prevents water damage and eliminates traditional drainage problems such as standing water in yards. The gravel-free interior provides 250% more detention volume than comparable sized gravel dry wells. What is a dry well? Traditionally an underground hole filled with heavy stone and gravel, with the Flo-Well Dry Well drainage system only a small amount of gravel is needed at the base of the tank to prevent scouring, and no heavy equipment is needed to install. Water collected upstream with a catch basin or channel drain is carried by pipes into the Flo-Well Dry Well, and seeps out through the open bottom and weep holes (punched out as needed). For local areas that require stormwater detention and infiltration on property, the Flo-Well Dry Well System is an accepted product, either installed by itself or as part of a larger integrated setup. The Flo-Well Dry Well also works well with rain gardens and bioswales to manage the flow and absorption of runoff from impervious surfaces.We’re here to help!

    My basement flooded with any storm that came through town. I had a french drain run around the inside of the basement, but the drain pipes sent all the water into the backyard, where it re-entered the house. I bought two of these and tied them into a roof gutter and the french drain. 2 weeks later remnants of a hurricane blew into town. Not a drop of water entered the basement. Great product and I plan to buy more for another house.

    We used this to bury a downspout that had been flooding a walk and creating ice in winter. Punched out a side hole and fed in flexible pipe from roof drain. One year later working great. Buried and surrounded with stone. Good for you and good for the environment. You do not want a bottom in it unless you are using it as a sump. Leaving the bottom open gives more infiltration area so I don’t really understand the other post.

    I purchased 2 Flo-wells to tie together for a french drain installation across the front of my house (partial basement). Once the 8′ pit was dug I noticed no water was leaching into the ground. After consulting with a contractor friend he informed me that the ground in the area is mostly clay with minimal leaching abilities. Soooo, time to re-engineer. I ended up buying another set of Flow-well sides and bottom so I could stack 3 Flo-wells and installed a Zoeller sump pump. Installation was a breeze and all is working very well!

    The well cost around $75, which was nearly the same amount as the stone that would have filled the same volume. However, the volume of water it handles far exceeds a simple stone dry well. Worth the investment.

  5. DrainageBoy

    These drywells helped a drainage problem I was having. The knock outs are a pain to remove. The unit was easy to put together.

  6. pantha1

    the ease from the box is a quick snap together unit. the instructions was simple to follow. i had some rain after installation of this system for a couple of days and my drainage problem is no more. system works very well.
