This video showcases an innovative rainwater collection system designed to reduce reliance on municipal water and provide a convenient water supply for homeowners, especially when they’re away. The system features a 600-gallon storage capacity using repurposed IBC totes connected in series, diverting water from a roof downspout located 125 feet from the garden. By utilizing low-pressure irrigation, the system efficiently manages water supply, cutting down on water waste and reducing the energy costs associated with treated water from Seattle Public Utilities.

A diverter regulates the flow of rainwater during different intensities of rainfall, ensuring that water is directed into the storage tanks without causing overflow or becoming a breeding ground for mosquitoes. The water is fed into the bottom of the tanks through a hose connection supported by the ground, allowing for flexible placement of the storage tanks in the garden where the water is most needed.

The rain tanks, elevated two feet above the plants, provide static pressure essential for the low-pressure irrigation system. This method not only conserves water but also repurposes materials, keeping project costs low. Over time, the system has evolved into a highly regulated management setup, offering a sustainable and cost-effective solution for managing water resources.
