Full turnkey catchment tank installation across all Hawaiian islands. Site assessment, tank selection, and certified installation — handled start to finish by an experienced crew.
A rainwater catchment system collects rain from your roof, channels it through gutters and downspouts into a storage tank, then pumps it through sediment filters and UV sterilization into your home. In Hawaii, a properly installed system provides clean, reliable water for drinking, irrigation, and everyday use.
Aina Water handles every step — from your first call to the day water flows clean from your tap. We assess your site, spec the right tank size and filtration, coordinate permits, and manage the installation with our certified crew.
Most residential installations on the Big Island, Oahu, Maui, and Kauai are completed in one to two days.
We visit your property across any Hawaiian island, assess your roof area, rainfall patterns, and water usage needs. We'll tell you exactly what size system you need, what it will cost, and how long installation takes. No charge, no pressure.
We spec the right combination of tank type (poly or corrugated steel), size (from 1,500 to 50,000+ gallons), filtration, UV treatment, and pump system for your property and usage. We walk you through every option.
Permit requirements vary by island and county. We handle all permit applications and county coordination so you don't have to navigate that process alone.
Our certified crew handles the full installation — tank placement and leveling, gutter and downspout connections, first-flush diverter, pump house setup, filtration and UV system, and final pressure test. Most residential installs are complete in one day.
We walk you through your new system — how to monitor tank levels, what to watch for, how to maintain it. You'll know exactly how your system works and what it needs.
We install both poly and corrugated steel water storage tanks across Hawaii. Both are proven for Hawaii's climate — your choice depends on site access, budget, and long-term plans.
Polyethylene tanks are a cost-effective, low-maintenance option for residential rainwater catchment in Hawaii. UV-stabilized for Hawaii's sun exposure and available in a range of sizes.
Heavy gauge corrugated steel tanks are Hawaii's best value for large-volume water storage. Built beyond engineer specs, these tanks are ideal for farms, ranches, and properties with high water demands.
Catching and storing water is only part of the system. Without proper treatment, rainwater catchment is not considered potable. Every Aina Water installation includes a complete filtration and treatment system sized for your tank and household needs.
