The Solarid Toilet progression in research and development.
The Solarid Toilet System approach
At Solarid Toilet System, our mission is to revolutionize sanitation through sustainable, people focused toilet solutions that work anywhere. We are setting the standard for what eco-conscious, waterless sanitation can be, and believe everyone deserves dignified access to clean, reliable toilets, without wasting water.

Aaron Ewerdt
CEO & PRESIDENT
I first started understanding the need for alternative forms of sanitation when I was building homes in Mexico in the early 2000s. The reality that a lot of those locations rarely use their flush toilets due to the cost of the water parallels new construction attempts in arid sections of the United States today.
The positive experience of replacing a chemical toilet with a Solarid Toilet at one of our work sites is leading our drive to have this solution as a viable option for any remote and off-grid site where a septic leach field is either too expensive or impossible.

Tom Pirelli
CHAIRMAN
Tom Pirelli has spent his career building tools that make everyday systems work better for people. He began as an engineer, designing one of the first electronic cash registers while at Princeton. His work in healthcare technology grew into Enterprise Systems, a company he founded and later took public.
Solarid reflects the same hands-on problem-solving that has shaped his path. Tom created the first Solarid Toilet for remote homes in the desert regions of Mexico, where water was limited. That design grew into today’s dry flush system. As Chairman of Solaris Systems, he is focused on bringing dignified sanitation anywhere it is needed.
Tom has passionately supported nonprofits, mentored young athletes, and invested in early technology teams throughout his career.
Our story
The first Solarid Toilet System was developed in 2011 during an affordable housing build in Baja, Mexico. Homes in the area were being constructed without reliable access to running water, electricity, or sanitation infrastructure.
Conventional flush toilets had been installed, yet for many families, the ongoing cost and inconsistent water supply made them difficult, and mostly impossible, to use and maintain. Some households stopped using them altogether. That reality shifted our focus from installing standard fixtures to designing a sanitation system that could operate independently of water access.
The first Solarid Toilet was installed in June 2011. It was introduced as a practical solution built to function within environmental constraints while providing a familiar toilet experience with zero water use.
Fourteen design iterations later, the Solarid Toilet System continues to carry forward the original intent: patented dry-flush technology that operates without water and performs reliably wherever infrastructure is limited, and zero water use is essential.
