If you shower or bathe in untreated rainwater, it is absorbed through your skin, eyes, nose, and every open pore.

Serving Rainwater Harvesters across Hawai‘i Island and island nation communities globally.
After assessing how I could best serve my community, one truth was clear—water matters most.
In Puna, where rainwater catchment is the primary household water source for many, I launched an educational platform, tank cleaning services, and monthly maintenance programs, including our Water Report Card, to support local Rainwater Harvesters.
This work is driven by a simple reality: The quality of our water is a direct link to the quality of our health.

Catchment Inspection Reports (CIR)
For properties served by rainwater catchment systems, a Catchment Inspection Report (CIR) plays a critical role in supporting health awareness, transparency, and informed decision-making. Because these systems are privately owned and not overseen by a municipal Water Department, the condition and performance of the catchment system directly affect the health of the user and the habitability of the home. For Realtors, a CIR provides documented risk awareness and supports informed disclosure, helping reduce surprises during escrow and protect all parties involved in the transaction. For users, the CIR establishes a clear understanding of system condition and water quality, empowering responsible ownership and confident use of their household water supply.
