Trench Drain Installation in Savannah, GA

Cost depends on the length of the drain run, the grate material chosen, and how much excavation and re-grading is needed -- a short residential run costs meaningfully less than a longer run or a commercial vehicle-rated system, which needs a heavier-duty channel and grate. A contractor can give an accurate quote after seeing the site.

Gutters and downspouts manage roof runoff, but they don't address surface water flowing across a driveway, patio, or yard during heavy rain -- which is a common issue on Savannah's naturally flat terrain with a high water table. A trench drain addresses this surface-level pooling directly, which a gutter system alone can't fix.

A trench drain is a surface-level linear channel with a grate on top, designed to capture water flowing across a hard surface like a driveway or patio before it pools. A French drain is a below-ground perforated pipe surrounded by gravel, designed to collect and redirect groundwater or subsurface water. They're often used together on properties with both surface and subsurface drainage issues.

It depends on how much debris (leaves, sediment, grass clippings) typically reaches the drain, but most residential trench drains benefit from a cleaning check at least once or twice a year, more often if there's heavy tree cover nearby -- common throughout Savannah's older, tree-lined neighborhoods. A clogged trench drain can back up and defeat the purpose of having one installed.

Yes, but it needs a different edge treatment than a paved surface -- the channel typically needs a solid, compacted border (often a concrete or paver collar) around the drain so the gravel doesn't shift into the opening or undermine the grate over time. A contractor familiar with gravel driveways can spec the right edging so the drain stays functional rather than getting buried or displaced.

Regrading alone works when the ground has enough natural slope and space to redirect water away from a structure, but Savannah's low-country terrain is flat enough in a lot of areas that there's nowhere for regraded water to go without a channel to carry it to an outlet. A trench drain is generally the better fit when you're seeing repeated pooling at a hard surface, garage entrance, or low point that grading alone hasn't fixed -- a contractor assessing the site can tell you which approach actually solves the problem.
