Question

What is the role of recharge trenches in recharging groundwater?

Answer 1

1. High-Volume Surface Capture: Trenches are long, shallow trenches that absorb rainwater from continuous surfaces like roads, paved driveways, and gently sloping land.
2. Maximizing Contact Area: Trenches, unlike pits, spread collected water across a considerably larger subsurface area, increasing the rate of percolation into shallow aquifers.
3. Stormwater Management: Stormwater Management: By capturing surface water across a large area, they considerably reduce urban flooding while also recharging the water table.
