Residential Rainwater Harvesting
Rainwater Management Solutions (RMS) delivers a comprehensive suite of residential rainwater harvesting services, supporting homeowners seeking sustainable, reliable, and cost‑saving water‑reuse systems. RMS provides full system design and consulting, helping homeowners understand their water‑use goals and develop systems that efficiently collect, store, filter, and distribute rainwater for landscape irrigation, household non‑potable and even potable uses. Their residential design services extend to light commercial properties as well, offering tailored solutions that offset municipal water usage and reduce utility costs where feasible.
Full Range of System Components
A major component of RMS’s service offering is expert equipment and component selection, ensuring homeowners receive the ideal combination of pre-filters, tanks, pumps, treatment units, and accessories for their specific environment and water‑use demands. The company supplies a full range of system components, including rainwater pre‑tank filtration technologies, storage tanks, pumps, and water treatment systems, all curated to minimize maintenance and optimize performance. RMS incorporates the trusted WISY 4‑Step Process, which uses pre‑tank filtration to reduce particulates, promote oxygenation, and maintain a healthier water environment, ultimately lowering system maintenance and prolonging the life of pumps and filtration equipment downstream.
RMS also supports DIY‑friendly residential solutions, offering packaged components and educational guidance for homeowners who prefer to assemble or maintain their own systems. Whether a homeowner’s goal is landscape irrigation, household water reduction, drought resilience, or long‑term sustainability, RMS provides the technical expertise and curated components needed to build a durable, efficient rainwater harvesting system.

How It Works — The WISY 4-Step System
We’ve identified the WISY 4-Step System as the gold standard for residential rainwater harvesting and we’re the exclusive North American distributor of the WISY product line.
Up tp 95% of collected water reaches your storage tank when the system is properly sized minimizing waste and maximizing efficiency.
- Pre-Tank Filtration: Removes rooftop debris before water enters storage
- Smoothing Inlet: Calms incoming water to prevent tank stirring and protect water quality
- Floating Filter: Draws the cleanest water from just below the surface
- Overflow Device: Safely manages excess water while keeping the tank protected
Common Residential Uses
Rainwater harvesting isn’t just for one purpose. A well-designed system can serve your entire home in ways that reduce your dependence on municipal water and lower your utility costs year-round. Your harvested rainwater can serve many purposes around the home:
- Toilet flushing
- Irrigation & landscape watering
- Vehicle washing
- Fire suppression
- Laundry
- Pool & pond filling
The Benefits of Harvesting Rainwater at Home
It Saves You Money
The best thing about rainwater is that it’s 100% free. Every gallon of harvested rainwater that replaces municipal water represents direct savings on your utility bill. RMS can provide detailed Return on Investment (ROI) projections for homeowners who want to understand the long-term financial value of collecting and reusing rainwater including potential offsets to municipal water usage and stormwater fees.
It's a Sustainable Choice
Harvesting rainwater is a simple, meaningful way to reduce your environmental footprint. By collecting and reusing water that would otherwise run off your property, you help protect local waterways from contamination, conserve groundwater resources, and reduce overall demand on shared water supplies. It’s one of the most practical steps a homeowner can take toward a more sustainable lifestyle.
