Designed in Hawaiʻi, for Hawaiʻi.‍

Mata is a septic tank alternative designed to treat your home's blackwater. Designed to be installed between your home and the cesspool, Mata is the first cesspool upgrade designed to be installed without excavation.
‍
Mata's compact, aboveground design captures solids and their harmful nutrients before they ever reach the soil, protectiong the surrounding environment and downstream ecosystems.

At just one tenth the size of a septic tank, Mata requires no excavation, no heavy machinery, and no disruption to your landscaping.

How It works
Mata is a Solid Waste Interceptor for cesspool upgrades on single-family homes. Unlike bulky septic tanks that settle out wastewater solids, Mata uses a compact screening and dehydration process to eliminate excavation and reduce cost.

Mata requires a minimum height of 14" from grade to the invert of sewer pipe leaving the home.
1. Blackwater flows passively into the Mata via the 3" inlet.
2. A screen separates solids while liquids drain to the bottom of the separator tank. An auger diverts solids to the solids bin for drying.
3. Separated liquids are pumped out via the effluent pipe to disposal.
Solids Bin
Mata separates solids from sewage and then dehydrates them for disposal. The inclusion of two solid bins allows one bin to be filled while the second is drying. Solids are removed, and the bins are swapped once every 1-12 weeks, depending on your usage. Solids can be reused or discarded according to local regulations. The entire bin swap procedure should take roughly 5 minutes.

Empty Bin Weight: 10lbs (4.5 KG).
Dehydrated Solids Weight: 20 lbs (9 KG).
Dimensions of Solids Bin: 14" X 14" X 14"
