French drain: Estimate $20.00 to $30.00 per linear foot. Where water stands in a swale or elsewhere, a French drain can be installed beneath the flow line to provide a clean avenue for the water to percolate deeper underground so the surface soil can dry out. Drop inlet sub-surface system: $8.00 to 10.00 per linear foot. Backyard landscapes often include a system of piping to gather water via strategically placed drop inlets or catch basins. The surface grades are all oriented to drain to the nearest drop inlet. Trench drain: $70.00 per linear foot.
