Key Features

Affordable Installation
Eliminate expensive excavation while minimizing disruption. Mata 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 and dehydrates 90% of blackwater solids, protecting your disposal system and environment.
No Odor
Post-separation solids are dried and odorless. Air from the system is filtered and vented away from your home.
Protect the Reefs
Due to its nutrient load, untreated sewage fuel algal blooms, which smoother reefs and reduce oxygen levels in the water.
Simple Permitting
As a UPC §1009 compliant solids separator, Mata doesn't require an expensive engineering design or time consuming permitting process.
[    Testimonial conducted next to Mata.    ]
“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
