This continuously running rain barrel irrigation system optimizes rainwater usage but also employs an innovative hose water back up system that keeps the system running when the barrels run dry.
I worked on perfecting this system for 10 years. It is the ultimate rain barrel irrigation system, in my opinion. The system includes:
Part 1: Rainwater Collection:
– 2 barrel system
– Seasonal diverter
– Overflow to downspout
Part 2: Pump System
– On-demand electric pump
– 45 psi
– DC / Solar Option
Part 3: Irrigation and Filtration
– 2 -stage filtration system
– Underground feed to garden
– Micro-drip irrigation system
– Automatic shutoff
Part 4: Backup Refill System
– Automatic hose water backup system
