Collection: Rainwater Harvesting

Transform runoff into a high-value asset. Professional rainwater harvesting is the foundation of modern, sustainable landscape engineering. By integrating advanced stormwater capture systems, property owners can mitigate soil erosion, meet stormwater mitigation compliance, and establish an independent water supply for irrigation, pond replenishment, and technical use.

Our solutions are engineered for LEED-aligned developments and professional landscapes across the USA and Canada. Whether you are designing a residential rain garden or a large-scale commercial water reuse project, our components ensure every drop is captured with maximum efficiency.

Rainwater Harvesting

The Architecture of Water Independence

Filtration & Pre-Storage Diversion: Advanced rainwater filters and diverters designed to intercept organic debris. Includes first-flush technology to isolate the most contaminated initial runoff from roofs and hardscapes.
Complete Modular Systems: From low-profile underground rainwater storage tanks to high-capacity complete systems. Engineered with UV-stable materials to maintain chemical neutrality and prevent algae growth.
Stormwater Velocity Control: Strategic harvesting reduces runoff pressure, preventing topsoil erosion and protecting the structural integrity of your landscape and water features.
Irrigation & Auto-Fill Integration: Naturally soft rainwater is the ideal resource for aquatic life and sensitive plantings, eliminating the mineral buildup and chlorine stress associated with municipal water.

Engineering Specifications: Rainwater Efficiency

Component Functional Requirement System Benefit
First-Flush Diverter Automatic isolation of initial 0.5-1.5mm runoff Prevents fine sediment & pollutant buildup
In-Line Filtration Stainless steel mesh (200-500 micron) Protects pump impellers and valves
Storage Reservoirs Light-tight, pH-neutral polymers Eliminates photosynthesis and biofilm
Intake Technology Floating intake filters Extracts the cleanest water from the "quiet zone"

All components are engineered for long-term outdoor exposure across North American climates, including freeze-thaw regions (Ontario, Alberta, New England) and high UV environments.

Maximizing the Lifecycle of Harvested Water

The efficiency of a rainwater collection system depends on the accuracy of your runoff calculations. Balancing roof catchment area with regional precipitation data ensures your system handles peak storm events without overflow or deficit.

Filters & Diverters: Primary Protection

Mechanical pre-filtration is critical. Our rain barrel diverters and high-flow filters handle massive volumes while remaining self-cleaning. By diverting the "first flush," you eliminate bird droppings and heavy sediment, extending the life of your underground rainwater storage tank. View Filters →

Complete Systems for Sustainability Compliance

We provide turnkey rainwater kits that act as a biological insurance policy for your landscape during municipal water restrictions. These systems are ideal for commercial properties seeking to reduce their water footprint and meet environmental runoff standards.

Pro-Perspective: Designing for Sub-Zero Climates

In regions like the Northern US and Canada, system geometry is vital. We recommend installing storage below the frost line to ensure year-round availability. For surface-level installations, seasonal winterization—including drainage of exposed diverters—is mandatory to prevent ice expansion damage.

Frequently Asked Questions About Rainwater Harvesting

How much water can I collect from my roof?

A general engineering rule is that 1,000 square feet of roof area captures approximately 600 gallons of water for every inch of rainfall. To optimize your stormwater capture system, we recommend sizing your storage capacity based on your region's average peak storm intensity to prevent frequent overflows.

What is a First-Flush Diverter and why is it necessary?

A First-Flush Diverter is a critical pre-filtration component that automatically isolates the initial 0.5-1.5mm of runoff. This initial water contains the highest concentration of roof pollutants, dust, and debris. By diverting it, you ensure only the cleanest water enters your underground rainwater storage tank, reducing sediment buildup and maintenance.

Do I need a permit for rainwater harvesting in the USA or Canada?

Permit requirements vary significantly by state and province. Most regions encourage rainwater collection for non-potable use (irrigation, pond filling), but some states have specific volume limits or reporting requirements. Always consult your local municipality to ensure your project meets stormwater mitigation compliance guidelines.

Is harvested rainwater safe for ponds and Koi?

Yes, rainwater is naturally soft and free of chlorine and fluoride, making it ideal for aquatic ecosystems. However, it is essential to use Fish-Safe/Potable-Safe certified components and liners (like 45-mil EPDM) to ensure no chemicals leach into the water during storage.
