Water equipment specialist

Hawaii Engineering Services (HES) is a dedicated specialist in water and wastewater equipment, systems, and support. We work closely with engineers, operators, and municipalities to specify, supply, and service solutions that perform reliably in demanding island environments. From pumps and controls to treatment and monitoring systems, our focus is on proven technologies and long-term system performance. Every recommendation is grounded in experience, technical knowledge, and real-world application.

From design assistance to equipment, service, and long-term support, we partner with our clients to deliver reliable solutions built for island conditions and beyond.
