Who We Are

At North American Rain Systems, we help people build practical water solutions by supplying the equipment and components needed for rainwater harvesting and water infrastructure projects that support independence, resilience, and long-term sustainability. Since 2009, we’ve focused on providing reliable rainwater system supplies for residential, agricultural, and commercial applications across North America.

We believe water is more than a utility — it’s essential infrastructure. Rainwater systems can support agricultural irrigation, livestock operations, backup and emergency water needs, and reduced dependence on municipal supplies. Our role is to ensure customers have access to dependable equipment that performs when it matters most.

Every water system is different, and selecting the right components is critical. We work with customers to understand their application and supply the appropriate tanks, pumps, filtration, controls, and accessories needed to support their specific use case — from simple rain catchment setups to larger-scale agricultural or commercial installations.

We carry a comprehensive range of proven products from trusted manufacturers and focus on equipment that is field-tested, durable, and well-suited for real-world conditions. Our experience in rainwater harvesting allows us to help customers make informed purchasing decisions and avoid costly mismatches or over-complication.

Rainwater harvesting supports water independence, strengthens sustainability efforts, and provides an added layer of security when water systems are stressed or unavailable. At North American Rain Systems, we exist to make access to reliable rainwater equipment straightforward, dependable, and scalable.
