BASIX makes wastewater management simple

Getting back to BASIX and better water stewardship

BASIX is a team of environmentally conscious professionals that are innovating the foundations of our wastewater management systems. 


One of our featured products uses a gut microbial system that consumes the waste from your wastewater to make it suitable for irrigation. These "living systems" completely change the way we look at septic systems. Easy to use & maintain, simple to install, and it saves a lot of water.

BASIX Solution reworks your wastewater management foundation from the ground up to enable you to recycle your water and save money through lower water bills and easy-to-maintain systems.

Les Miyashiro and his team did an outstanding job assisting our family with all the septic and environmental issues we faced over several years.
