Santa Cruz Permaculture: Berm & Swale Rainwater Earthworks
PermaNews Brief
Key Takeaways
Berms and swales are effective permaculture earthworks for rainwater harvesting, improving soil moisture, and preventing erosion on sloped land.
- Install berms and swales perpendicular to slopes.
- Offset spillways to prevent erosion.
- Maintain vegetated strips for stability.
- Prioritize water infiltration over runoff.
- Utilize simple, low-cost earthwork techniques.
Why It Matters
Implementing berms and swales can drastically reduce water runoff, increase groundwater recharge, and foster healthier, more resilient ecosystems, especially in areas prone to drought or erosion.
What to Do Next
Identify a sloped area on your property and conceptualize where berms and swales could effectively redirect and retain rainwater.
Recommended for: Homeowners, gardeners, and land managers seeking efficient, low-cost rainwater harvesting and erosion control solutions for sloped terrains.
This resource explains the use of berms and swales as simple, low-cost earthworks for rainwater harvesting. Berms and swales are constructed perpendicular to slopes to intercept and infiltrate rainwater, improving soil moisture and reducing erosion. The article highlights best practices such as offsetting spillways and maintaining vegetated strips to maximize water retention and soil health.
