Above-Ground Wastewater Systems: Greg Wong on WaiHome’s Mata

Greg Wong of WaiHome explains how Mata separates wastewater solids above ground and why Hawaii's difficult sites make cesspool upgrades costly. Scott Andreasen explores site suitability, liquid disposal, maintenance and the business lessons behind developing a regulated product.

On the Excavation & Septic Profits Podcast, WaiHome co-founder Wong shares why he and James Roberts shifted their focus from aerobic treatment to primary solids separation. He describes Mata's screening and auger process, heat treatment and drying of captured solids, and the quality-control work behind the IAPMO Z1167 certification he discusses. Certification does not replace project-specific permitting or suitable liquid disposal.

Mata is an above-ground solid waste interceptor, not a complete replacement for every septic treatment and disposal requirement. Suitable liquid disposal, any required additional treatment and local permits still apply. Wong describes an initial focus on raised-foundation homes that can feed the unit by gravity. Appliance installation may avoid excavation on suitable properties, but base preparation, plumbing and disposal-site work can still be necessary.

Excavation and septic contractors will hear why rock, slopes and small lots affect installed cost, and why equipment price alone is not the whole estimate. Pricing and solids-removal intervals mentioned are Wong's interview examples, not current offers or guaranteed savings. Solids handling and any reuse remain subject to applicable rules.

The conversation also covers grant-funded development, complementary founder responsibilities, hiring and careful expansion. Wong credits organizations including the National Science Foundation and NOAA with helping provide development runway.
