Mata Solid Waste Interceptor

No excavators, no pump trucks.
Mata installed next to a small studio home in a lush tropical valley.
Mata is the first wastewater technology designed to improve the operation of cesspools, elevating treatment levels beyond what an entire septic system offers.

Mata's compact aboveground design means solids and their detrimental nutrients are captured and treated before ever entering the soils: protecting your disposal system, surrounding environment, and downstream ecosystems.

At 1/10th the size of a septic tank, Mata requires no excavation, no large machinery, and no massive disruptions to your landscaping.

Whether you have a failing cesspool or need a completely new system, skip the headaches. Choose Mata.

Key Features

Affordable Installation
Eliminate expensive excavation while minimizing disruption. Mata installs just like an appliance.
Works with Indoor Plumbing
Mata is not a composting system, it dehydrates solids; handling all your treatment needs without changes to your fixtures, faucets, or habits.
Reduce Solids Pumping
Mata captures 90% of solids before they go into your disposal system. Stopping pollution at the source.
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
As a UPC §1009 compliant solids separator, Mata doesn't require an expensive engineering design or time consuming permitting process.

Liquid Disposal

With the solids safely treated, liquid disposal now becomes a point of focus. Due to Mata's modular design, liquid effluent disposal or additional treatment can be defined by what bests suits your properties needs. A few examples of disposal pairing options are Sawas, seepage pits, soil dispersal, or future cluster treatment.

“Well, I didn’t even know anything had changed.” Cristina
‍
“The beautiful thing is that it’s so simple and there’s nothing much to do, but also just, honestly speaking, I appreciate the good feeling I get from it. I know humans have such a negative impact, and this has just had a positive impact, turning our waste into something useful. Just putting the water back in the ground without the solids makes me feel better about our valley.” Mark

Cristina & Mark, Property Owners

Mark and Cristina installed two Mata’s for the ohana units on their property - 6 Months later we asked how it was going.  

“You can’t even smell it and we’re standing right here…It hasn’t had any effect on our day-to-day life. Pretty Insane” - Angela
