Material	Cost/Unit	Pros	Cons	Best For
Perforated PVC Pipe with Gravel Bed	$5-$15 per linear ft (materials only)	Proven, widely understood, easy to inspect and repair, gravel provides excellent void space for water movement	Labor-intensive installation, gravel is heavy to transport, fabric can silt up over 10-15 years	Standard residential french drains, perimeter drainage, yard drainage in most soil typesProven, widely understood, easy to inspect and repair, gravel provides excellent void space for water movement

Channel / Trench Drain (Surface)	$20-$45 per linear ft (materials only)	Handles large volume surface water quickly, grate is removable for cleaning, works in areas where sub-surface drain isn't possible	Visible on surface, grates must be kept clear of debris, may require concrete surround to install properly	Driveways, patios, and hardscape areas where water pools on the surface rather than saturating the soilHandles large volume surface water quickly, grate is removable for cleaning, works in areas where sub-surface drain isn't possible
