Rainwater Harvesting and Beyond
About Myself

DBG Yearly Water Usage:
Water Usage &
RWH Potential
1. Irrigation do not reach some plants- water is wasted while plants struggle
2. Water is flowing away from plants- trails are flooded
3. Many unused but open spaghetti lines- one gallon (at least) is wasted each operating hour

Recommendations for Harvesting:
- Permeable materials for paths, roads, and parking lots - allow percolation
- Pathways above beds - allow water to flow off surface to the gardens.
- Slopes for impermeable materials - allow rainwater drainage onto landscape
