About Us

H2O Process Systems is a locally owned and operated firm that offers a full spectrum of wastewater treatment services to our customers. Since 1995, we have provided innovative solutions for the needs of engineers, plant operators, developers, and many more both on island and around the world.


We offer a wide variety of wastewater treatment equipment and we work hand in hand with our customers to find exactly what they need at a cost that works for them. In addition, we offer a full range of engineering and support services including planning, set-up, installation, project management, operations, and maintenance to ensure that every job is done thoroughly. 

Our team has completed jobs across all main islands, the continental US, and Guam for both public and private entities. For us, the relationship with a customer never ends with a sale or after a project is complete. Instead, we pride ourselves on building lasting bonds and trust with those we work with in order to ensure quality work and service. We'd love to connect with you and see if we can add value.
