Dry Well Installation in Columbus, Ohio

Transit & Flow Group installs dry wells across Columbus and Central Ohio as a below-ground destination for water that a French drain, a buried downspout line, or a channel drain has already collected but needs somewhere lawful to go. A dry well is a buried gravel pit or a perforated plastic chamber set below the frost line, sized to hold a volume of water temporarily and let it percolate slowly into the surrounding soil instead of daylighting onto a lawn or a neighbor’s property. Describe your drainage source and yard in the Estimate Builder for a preliminary online estimate.

Is this the right service for you?

A dry well is usually the right answer when:

• You already have a French drain or downspout line with nowhere good to send the water. Daylighting onto a slope works when you have one; a dry well works when you do not.
• Your lot is flat or gently sloped, without an obvious downhill point to route water away from the house.
• A neighbor’s yard sits downhill, and discharging water onto their property is not something we will design, since that is not a lawful outlet.
• You want downspout water to disappear underground rather than run across the lawn to the street.
• An existing outlet has failed or was never built, and standing water collects where a pipe simply stops.

A dry well disperses water into the soil; it does not intercept water at the surface. If your problem is standing water in the yard itself rather than water that is already collected and piped somewhere, you likely need a French drain first (see our French Drain Installation page) or a buried downspout line (see Buried Downspout Drainage), with the dry well as the termination point for either.

How pricing works

Dry wells are priced as a range based on soil and volume, not a flat fee. What sets the number:

• Well type. A gravel-filled pit costs less than a pre-formed plastic chamber system, and a plastic chamber costs less than a concrete structure; each has a different capacity and lifespan.
• Size and depth. The well has to be sized to the volume of water it will actually receive, whether that is one downspout or an entire French drain system, and depth is set by soil conditions and frost line.
• Soil percolation. Central Ohio’s clay drains slowly, so a well here often needs to be larger, or paired with a properly sized overflow, compared to the same job in sandy soil.
• Access and excavation. A dry well in an open side yard costs less to dig than one placed near a foundation, tree roots, or existing hardscape.
• Overflow provisions. A well that can overflow safely to a secondary point during an extreme storm is priced as its own line, and we recommend it on most Central Ohio clay sites.

What’s included

• On-site assessment of the water source, volume, and available yard space
• Excavation to the depth and dimensions the design calls for
• Gravel, fabric, and chamber materials sized to the expected water volume
• Connection to the existing French drain, downspout line, or channel drain feeding the well
• An overflow provision where the site calls for one
• Backfill and rough grading over the completed well
• Photos of the open excavation for your records
• All workmanship is backed by a 1-year labor warranty on labor, parts, and equipment covered per manufacturer terms.

What’s not included

• French drain trenching to feed the well, quoted separately (see French Drain Installation)
• Buried downspout piping to feed the well, quoted separately (see Buried Downspout Drainage)
• Sump pump work, unless bundled into the same project
• Full landscape restoration beyond rough grade, unless added to the scope

According to HomeAdvisor’s 2025 cost data, professional dry well installation typically runs $1,344 to $5,139, with gravel wells at the lower end and concrete structures reaching higher. That figure is general market context, not a Transit & Flow quote, since soil percolation and volume on your lot change the real number.

Why Central Ohio yards need dry wells

Central Ohio’s clay soil barely absorbs water, which is exactly why a dry well here has to be engineered rather than dug as a simple hole. In sandy or loamy soil, a modest gravel pit disperses water quickly. In our clay, percolation happens slowly, so a well sized for a sandy-soil rule of thumb can back up and overflow during a heavy storm. That is why we size Central Ohio dry wells with a margin and, on most sites, an overflow path to a safe secondary point.

Freeze-thaw winters and heavy spring rain both add pressure to the system. A dry well has to sit below the frost line to function reliably through winter, and it has to handle the volume of a hard spring rainstorm without surfacing. Newer subdivisions in Lewis Center, Dublin, and New Albany present their own version of the problem: construction regrading compacted the clay subsoil during the build, leaving a dense layer just under the topsoil that drains even more slowly than undisturbed clay. On these lots, a dry well often needs to be larger or deeper than the same job would require on an older, less compacted lot, and our assessment accounts for that before we design it.

Our process

1. Describe your water source online. Tell us whether the well is terminating a French drain, a downspout line, or another system, with photos, in the Estimate Builder for a preliminary online estimate.
2. On-site assessment. We evaluate soil, available space, and the volume the well needs to handle. Final scope and price subject to verification here.
3. Design and proposal. A written plan covering well type, size, depth, and overflow provisions, each priced.
4. Excavation and installation. Dig to depth, place gravel or the chamber system, connect the feeding line, and add the overflow if the site needs one.
5. Backfill and test. We hose-test the connected system before backfilling, then restore the rough grade.
