Efficient Rain Collection System with Deviator Technology ✔ Saves $500-$1,000 annually on water bills ✔ Supports eco-friendly landscaping and drought-resistant gardening ✔ Scalable design for future expansion

Smart Water Management for Sustainable Gardening

This rainwater harvesting system is designed to maximize water efficiency and reduce reliance on municipal water. Using Deviator water redirection technology, the system collects and stores 900 gallons of rainwater for irrigating five raised garden beds.

The system captures rainfall from two 500-square-foot roof areas, capable of collecting up to 5,000 gallons between April and October. Instead of becoming runoff, the water is redirected into two 450-gallon rain tanks, creating a sustainable and renewable water source for outdoor use.

Environmental & Financial Benefits

  • Cost Savings: Reduces water bills by $500–$1,000 annually (based on 2025 rates).
  • Sustainability: Converts rainwater into a valuable irrigation resource for landscaping.
  • Efficiency: Strategically placed tanks optimize collection and distribution for maximum impact.
  • Aesthetic Integration: Tanks are discreetly positioned for a seamless, space-saving design.
  • Start Your Own Rainwater Harvesting System

System Components and Design

At the heart of this smart water management system is the Deviator water redirection technology, designed to optimize rainwater collection at the source. Installed at the low points of the gutters, the Deviator allows for precise control over water flow before it enters the downspout. Built-in screens prevent debris, such as leaves and twigs, from entering the system, ensuring clean water collection with minimal maintenance.

Key components of this DIY sustainable gardening water solution include:

      • Deviator water redirection system – Controls water flow and prevents clogging

      • Two 450-gallon rain tanks – Positioned 75 feet apart, with one elevated 8 feet above the garden beds for gravity-fed irrigation

      • Gutter filtration system – Keeps out debris for cleaner water storage

      • Rain collection and redirection hoses – Ensure efficient water transfer and prevent overflow

    This water-wise irrigation system efficiently distributes rainwater without pumps or additional energy inputs, making it a cost-effective and eco-friendly choice for homeowners


    Environmental Impact and Water Conservation

    Harnessing Seattle’s abundant rainfall, this system captures up to 10,000 gallons of water annually, converting what would otherwise be wasted runoff into a sustainable water supply. By providing eco-friendly water solutions for their five raised garden beds, the homeowners significantly reduce their dependence on municipal water sources, contributing to long-term water conservation efforts.

    Additionally, the system plays a critical role in stormwater management. The Deviator is strategically connected to the bottom of the rain tank via a redirecting water path, allowing efficient filling without overflow. When the tanks reach full capacity, the system’s built-in check valve prevents excess water from entering, ensuring that any surplus rainwater flows safely through the downspout into the home’s existing drainage system.

    By reducing stormwater runoff, this project helps prevent pollutants from entering Seattle’s waterways, protecting local streams and ecosystems from urban contamination. This eco-friendly water system not only supports personal sustainability goals but also benefits the broader community by mitigating the impact of excessive runoff on city infrastructure.

    Future Expansion and Adaptability

    Designed with long-term sustainability in mind, this system offers flexibility for future expansion. The homeowners plan to install a third 450-gallon tank near Tank 1, further increasing capacity and enhancing irrigation efficiency. This modular approach ensures that the system can adapt to evolving needs, making it a scalable solution for water conservation and sustainable home improvements.

    Conclusion

    This West Seattle rainwater harvesting project showcases how water efficiency strategies can create lasting environmental and financial benefits. By integrating innovative technology like the Deviator, these homeowners have implemented a smart water management system that reduces costs, conserves resources, and supports drought-resistant gardening.

    As concerns about water scarcity continue to grow, solutions like this provide a practical, eco-friendly blueprint for others looking to invest in water-wise irrigation systems. This initiative proves that with strategic planning and the right technology, homeowners can turn simple ideas into impactful results—benefiting both their property and the planet.

    Why This Matters

    For homeowners, urban planners, and sustainability advocates, projects like this highlight the power of eco-friendly water systems in reducing environmental impact while offering smart, cost-effective water management solutions. Whether you’re interested in rainwater harvesting, stormwater control, or efficient irrigation strategies, this case study provides a valuable roadmap for integrating sustainability and savings into everyday living.

    How does the deviator work?

     The deviator connects your gutter to your rain  tank. Rain tanks can fill from the bottom up. Using gravity, water can flow horizontally. Using horizontal flow is a great improvement as opposed to only vertically flowing water.

     

    Deviators go through the gutter and direct rainwater

     There is no overflow. The deviator gutter insert and the ring tank is a sealed delivery system. When the tank fails to capacity back pressure in the hose acts as a check valve preventing water overflowing. Now the water passes over the deviator inside the gutter and is directed down the downspout into the homes drainage system.

     

     Tanks are connected together through a 3/4” garden hose. The tanks are connected at the bottom. Water pressure pushes the water from one tank into the other, often times uphill. This system is a perfect setup, as the primary watering tank is five feet above the planter beds, perfect for managing your stored rainwater. (please note, in these pictures, the watering components have not been connected–is it is February and we just installed the system.
