Mata Solid Waste Interceptor

No wastewater permits, no excavators, no pump trucks.

Drawing of a Mata installed next to a post and pier home with it's outflow going into an existing cesspool.

When your cesspool clogs or overflows, you shouldn’t have to spend tens of thousands replacing it. Work with a licensed plumber to install the Mata unit before your existing cesspool to intercept and dehydrate solids before they end up in your cesspool, reducing backups and costly pump-outs.

Designed for tight lots, steep slopes, and island soils, it’s a simple step that protects your home and Hawai‘i’s waters.

Key Features

Affordable Installation

Improve performance of your cesspool with a product that installs just like an appliance.

Don't Change a Thing

Handles all your treatment needs without changes to your fixtures, faucets, or habits.

Reduce Solids Pumping

Mata separates 90% of blackwater solids: protecting your cesspool from clogs.

No Odor

Post-separation solids are dried and odorless. Air from the system is filtered and vented away from your home.

Protect the Reefs

Untreated sewage carries nutrients that fuel algal blooms. Keeping solids out of the ground keeps nutrients out of the coasts.

Simple Permitting

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

Install Process

01 | Install Concrete Pad

A 3" concrete pad is installed to provide a stable foundation for your Mata.

02 | Install Mata on Sewer Before Cesspool

After the concrete is dry we can come back to complete your install. This starts by routing your sewer line through the Mata.

03 | Install Vent

The Mata is vented to your roof line via a new vent stack.

04 | Restart Cesspool

We recommend a pump out and sulphuric acid treatment to restart your cesspool on the right foot from day one.

Mata and the Mandate

Currently, 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 developing Patu and Sawa — excavation free liquid treatment and disposal systems that work with Mata to complete your cesspool replacement before the 2050 deadline. We are currently working with regulators to make this a fully permitted solution and are gearing up for statewide use.

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.
