Story

In 2013, filmmaker and activist Ryan Beltrán founded elequa as a tech startup focused on an emerging method of water purification known as electrocoagulation. Elequa quickly garnered national attention, industry acclaim, and professional accolades for Beltrán due to the process’s unique, lower cost, and adaptable model of water purification. Several strategic partnerships, including with the education department of the San Antonio Water System (SAWS), led to the development and distribution of coagulation kits and STEM-focused educational program, Make Water.

With Make Water entering its fourth season in regional private and public schools, elequa Board leaders noted the organization’s natural fit in a nonprofit structure, and decided to pursue a nonprofit status. Today, elequa is a 501(c)3 nonprofit organization committed “to empowering students who want to make a difference in this world by giving them the tools to tackle real-world water issues collaboratively.” As STEM-based programming continues to gain priority at all levels of education, elequa looks forward to providing a low-cost, multi-faceted, and collaborative program that encourages students to be heroes, work together, and care for their environment and fellow human beings.
