Water Infrastructure designed in Hawai'i for Hawai'i.
Hawai‘i’s wastewater crisis is more than an ecological problem — it’s a social one. Across the islands, aging cesspools are quietly releasing millions of gallons of pollution into the ground every day and the options to fix it just aren't affordable.
WaiHome was founded in 2021 from a simple belief: wastewater solutions that force homeowners into debt aren't solutions. We set out to design systems that were affordable and rooted in the realities of island living.
Location
Nearly 35% of homes still rely on cesspools, many located in flood-prone or high groundwater zones. This means that 53 million gallons of untreated sewage enters our ground and coasts every day.
Legislation
New cesspools have been banned statewide. By 2050, 84,000 existing cesspools must be upgraded or replaced. Without affordable solutions, Hawai‘i risks missing this critical deadline.
Insufficient Choices
In coastal regions, septic tanks frequently fail due to high groundwater and saltwater intrusion. Digging leach fields into porous volcanic soil pushes contaminants into aquifers and nearshore springs
Cost of Excavation
Replacing cesspools with septic tanks is out of reach for most homeowners. With installation costs between $20,000 and $60,000, septic systems are unaffordable for 97% of households.
