Zaytuna Farm's Water Harvest: LiDAR, Swales, 50mm/hr Infiltration
By Darren Doherty
PermaNews Brief
Key Takeaways
Integrated water systems at Zaytuna Farm demonstrate significant ecological and economic benefits through strategic design and implementation.
- Keyline, swales, and wetlands dramatically increase water infiltration and retention.
- LiDAR data is crucial for precise contour mapping and system design.
- Integrated livestock management positively impacts soil fertility and structure.
- Water harvesting systems can yield substantial financial returns.
- Careful planning and construction are essential for system success.
Why It Matters
Implementing integrated water harvesting can transform land productivity, enhance ecosystem health, and generate significant economic savings for farms in various climates, offering a scalable model for regenerative agriculture.

Darren Doherty's 2024 video walkthrough of Zaytuna Farm (Australia) details keyline, swales, and wetlands integration, backed by LiDAR data, 50mm/hr infiltration rates post-install, livestock effects, and 20% irrigation ROI. Farm spans 100+ ha with keyline plowing (tractor rippers to 1.2m), swales (2m wide, rock-lined), wetlands (0.5ha ponds with emergent zones). LiDAR surveys (1m resolution) map contours ±10cm accuracy. Infiltration tests: Pre 5mm/hr to 50mm/hr via dual ring infiltrometers. Soil tests show OM +3%, bulk density -20%. Livestock (cattle rotation) enhances via trampling, adding 15% fertility. ROI: 20% irrigation cut equals $50k/year savings. Blueprints cover pond volumes (10ML), pipe specs (PVC 150mm). Construction seq: Keyline first, then swales every 40m contour, wetlands at lows. Video timestamps designs, drone footage, soil cores. Maintenance: Swale mulch annual, pond aeration via fountains. Yields: Pasture +35%, tree crops double. Challenges: Initial pond sealing with bentonite. Scalable to 10-1000ha. Compared standalone, integration multiplies effects (synergy index 2.5x). Data from 5 years rainfall (400mm avg). Practitioner tools: Free LiDAR downloads, A-frame builds. Livestock protocols: 1 day/acre paddocks. This PRI channel tour offers visual steps, Q&A, making complex harvesting accessible for regenerative designers.
