Zaytuna Farm's Water Harvest: LiDAR, Swales, 50mm/hr Infiltration
By Darren Doherty
TL;DR: 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.
