DIY Earthbag Cistern: 14k Gal Rainwater Harvesting
By Our Self-Reliant Life
TL;DR: A homesteading couple innovates a large-scale, off-grid earthbag cistern for rainwater harvesting, integrating gabion support for resilient water storage.
- Build a robust earthbag cistern for off-grid water.
- Layer and tamp earthbags for wall stability.
- Integrate gabion system for structural reinforcement.
- Install pipe systems for efficient water distribution.
- Ensure watertight seals and reinforcement against pressure.
Why it matters: This approach offers a sustainable, low-cost solution for water independence, crucial for homesteads in drought-prone areas and reducing reliance on municipal resources.
Do this next: Watch the video to understand the initial construction phases and pipe system integration.
Recommended for: Homesteaders and permaculture practitioners looking for robust, off-grid water storage solutions using natural building techniques.
In this practical video from the channel 'Our Self-Reliant Life,' a couple documents their construction of a massive earthbag cistern designed for off-grid rainwater harvesting on their homestead. The project aims to achieve self-sufficiency and sustainability by storing close to 14,000 gallons of water, essential for growth and maintenance in a homestead setting. They emphasize this as one of their biggest projects, highlighting the scale and ambition. Key methods include using earthbags filled with dirt to form the cistern walls, combined with a gabion retaining system for structural support and stability. The video covers the initial stages of building, including pipe systems that erupt with water flow, demonstrating successful rainwater collection and distribution. Practical insights include lessons on site preparation, material sourcing like local dirt and bags, and integration with off-grid living where water is piped directly for use. They discuss challenges such as ensuring watertight seals and reinforcement against pressure from the large volume. The cistern supports drought resilience by providing a reliable storage buffer, allowing continued homestead operations during dry periods. Viewers learn concrete steps like layering earthbags in courses, tamping for density, and incorporating gravel or mesh for reinforcement, similar to rammed earth techniques adapted for water containment. This regenerative approach aligns with permaculture principles by mimicking natural water retention landscapes, reducing reliance on municipal supplies, and promoting biodiversity through sustained irrigation. The couple shares real-time progress, troubleshooting like leak prevention with plaster or cement coatings, and long-term maintenance tips such as periodic inspections and cleaning of inlet filters. This hands-on case study offers actionable details for practitioners building low-cost, durable cisterns using accessible materials, with total costs kept low through DIY labor and scavenged resources. It inspires replication in permaculture contexts, proving that untrained homesteaders can achieve professional-grade results with determination and iterative learning.
