The Solarid Toilet System approach.

At Solarid Toilet System, our mission is to revolutionize sanitation through sustainable, people-centered toilet solutions that work anywhere. We believe everyone deserves dignified access to clean, reliable toilets, without wasting water.

Our vision is a world where sanitation works anywhere, wastes nothing, and serves everyone. We are setting the standard for what eco-conscious, waterless sanitation can be: simple, effective, and built for people first.

    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

    FOUNDER

    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.

Solarid Toilet System was born in 2011, when our founder built homes for families in Baja, Mexico. Water was scarce, and flushing it away was not an option. The first Solaris Toilet was designed there—a waterless system that offered dignity and safety where no sanitation had existed before.
