Mata Solid Waste Interceptor, Installed next to a home on a small concrete pad. Mata is a steel blue/grey color.

Designed in Hawaiʻi‍

Mata is a compact, above-ground solid waste interceptor designed in Hawaiʻi to meet the islands’ unique geographic and environmental challenges. Installed before a cesspool, leachfield, or sewer connection, it captures solids early — preventing clogs, reducing pump-outs, and keeping contaminants out of groundwater and coastal waters.

Unlike conventional septic systems that require excavation and costly pump-outs, Mata installs on-grade quickly and adapts to almost any site — from tight residential lots to remote developments. Built for island conditions and future-ready design standards, it offers an affordable, low-impact solution that protects both your property and Hawaiʻi’s ecosystems.

How It works
Mata is a single-family Solid Waste Interceptor for disposal environment protection. Unlike bulky septic tanks that settle out wastewater solids, Mata uses a compact screening process to eliminate excavation and reduce cost. Mata is permitted as an Interceptor under §1009.0 of the Uniform Plumbing Code.

Mata requires a minimum 12" from grade to the homes outflowing sewer pipes' invert.
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.

Design Considerations
‍
Position: Mata can be orientated perpendicular or parallel to house. For homes with a high post and pier foundations, Mata can be placed underneath the home.

‍Clearance: 3’ clearance required in front of solid bins for maintenance.
‍
‍Other: All installations should conform to local regulation. Not for use in regions prone to freezing temperatures.

Vent | 1.5” Dia.

Inlet | 3” STD Pipe, >12" invert above grade, Gravity fed.

Overflow Drain | 1.5” Dia. Check valve, no shut off.

Pumped Effluent | 1.5” Dia. Route to disposal area.

Emergency Drain | Gate valve.

Solids Bin
Mata separates solids from raw sewage and then dehydrates and sterilizes 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 4-12 weeks, depending on your usage.

Empty Bin Weight: 10lbs (4.5 KG).
Dehydrated Solids Weight: 20 lbs (9 KG).
Dimensions of Solids Bin: 14" X 14" X 14"
Step 1 of the solids bin exchange process. Solids bins are both in place infront of mata.Home owner is moving the solids bin that is full, preparing to remove the dehydrated solids.Homeowner is removing the dehydrated solids bag from the initial solids bin - solids look lite. Soldis bag is a black mesh bag.Solids bin is shown without lid and an empty solids bag, preparing to be exchanged.Both solids bin are back in position infront of the Mata, the homeowner has left the frame.
Step 1.

Mata runs for 4 - 12 weeks.

Step 2.

Remove solids bin with aged solids.

Step 3.

Withdraw aged solids.

Step 4.

Insert new solids bag.

Step 5.

Slide fresh bin over for aging and position empty bin to receive fresh solids.

Technical Information
The Mata underwent six months of third-party water testing with the University of Hawai'i, which concluded in December 2025.
