What we do
Complete Systems, Built for Your Property
Every system is designed specifically for your land, your needs, and your long-term water independence.
Custom System Design
We assess your property, rainfall patterns, and water needs to engineer a system that maximizes collection and storage — no templates, no guesswork.
Whole-Home Potable Water
Full residential systems that deliver clean, safe drinking water from rainfall — designed to meet or exceed municipal water quality standards.
Cistern Installation
Above-ground and underground storage solutions sized for your property's collection capacity and seasonal demand.
Filtration & UV Disinfection
Multi-stage filtration and UV treatment systems that remove sediment, bacteria, and contaminants — delivering reliably pure water.
Maintenance & Inspections
Scheduled maintenance, system inspections, and water quality testing to keep your system performing at peak efficiency year-round.
Battery Backup & Energy Resilience
Keep your rainwater pump, pressure controls, UV treatment, monitoring equipment, and selected essential circuits operating through grid outages with professionally designed battery storage, automatic transfer, and intelligent load management.
Water + Power Resilience
A Water System Is Only Reliable When Its Power Is Reliable.
Stored water cannot serve your property if the pump, pressure system, or UV treatment loses power. RainRise designs coordinated battery-backup solutions that keep your water system operating while also supporting selected household or business essentials.
Automatic Backup
Properly configured systems respond automatically when grid power is interrupted, helping maintain water pressure and essential electrical service.
Essential-Load Planning
We identify the equipment that matters most—from pumps and water treatment to refrigeration, internet, lighting, and selected comfort systems.
Scalable Technology
Start with the capacity you need today and prepare for future battery expansion, solar charging, or generator integration.
16–32 kWh

Why RainRise
Built on Real Experience
Our founders have spent years operating properties that run entirely on harvested rainwater. That real-world knowledge shapes every system we design.
Not theory — we've lived on rainwater systems and understand what works in East Tennessee's climate.
No one-size-fits-all packages. Every system is engineered for your specific property, rainfall, and water needs.
We know the terrain, the rainfall patterns, and the regulations. We're your neighbors, not a national franchise.
We stand behind every installation with ongoing maintenance, inspections, and honest advice for the life of your system.
