Stop Washing Machine Erosion on a Slope

Greywater Catch Basin

Sink a large plastic trash can (30–55 gal) or livestock tank at the pipe outlet. Drill drainage holes in the bottom, add a gravel layer. Water collects, then percolates slowly.

Upgrade Options

• Add a submersible pump to reuse water for irrigation.
• Dual-tank system: primary for immediate infiltration, secondary for storage.

Erosion-Control Planting

Plant liriope, lovegrass, daylilies, ivy, or sedums at the outlet. Their roots hold soil. Use phosphate-free detergent to protect plants.

Terracing

Build low retaining walls (berms) to create level steps. Labor-intensive but permanent.

Check Local Codes

Some municipalities regulate greywater discharge.
