Mata Solid Waste Interceptor

No pits, no excavators, no pump trucks.

Starting from scratch should be an opportunity — not a challenge. Traditional septic systems demand excavation, permits, and high upfront costs, while composting or dry systems can compromise comfort and convenience. The Mata system bridges that gap — providing a flush-ready, aboveground solution that’s easy to install, modular by design, and built for Hawai‘i’s terrain.

✓ Easy Install
✓ Space-Saving
✓ Eco-Friendly

This site showcases a holistic treatment system featuring WaiHome's Mata for solids separation, Patu for additional liquid treatment, and Sawa for excavation-free disposal under the deck.

Permitting Process

Mata is a UPC §1009 compliant solids separator, meaning it just needs an over-the-counter plumbing permit and install by a licensed plumber.

However, our work doesn’t stop with Mata. We’re also working with the University of Hawaiʻi and regulators to certify our excavation free Patu liquid treatment unit and Sawa leachfield for permitted installation across Hawai'i.

Mata Maintenance

Mata separates solids from raw sewage and then dehydrates and steralizes them for disposal. The inclusion of two solids bins allows one bin to be filling while the second is drying. Solids are removed and the bins swapped once every 4-12 weeks depending on your usage.
