About WaterWise

Over 30,000 Big Island homes depend on rainwater catchment

Living off-grid in Puna means your family's water comes straight from the sky. That's the beauty of Hawaii—but it also means your health depends on a system that actually works.

We're your neighbors in Hawaiian Paradise Park. We understand the heavy Puna rains, the VOG that settles on roofs, the humidity that breeds bacteria. We build and maintain systems designed for this climate.

Rainfall & Maintenance
