Despite the fact that it covers 70 percent of the Earth's surface, water is in a state of scarcity throughout much of the world. Trying to find new, sustainable ways to provide water to the masses is something municipalities work towards every day. And in places like California, it is a task Water Managers are more than familiar with, as the state faces one of the most severe droughts on record. RMC Water and Environment custom tailors innovative approaches for our clients to provide long-term sustainable water supply solutions to their customers.


RMC’s leaders take an active role in day-to-day project work, allowing us to respond to clients’ needs with the personal attention of experienced staff.

Why We're Different

Work as One Company

RMC’s streamlined structure promotes interaction among staff at all levels and makes it easy for local offices to work together collaboratively. We support camaraderie by getting the entire company together yearly and by holding local “fun days” where colleagues can get to know each other beyond the walls of the office.

RMC staff photo from year four

In 1998, RMC’s co‐founders walked away from mega‐sized engineering companies to build a new kind of consulting engineering firm. Hands‐on professionals, they built RMC with a flat organizational structure to support company principals in actively serving clients and developing the best possible solutions to complex water‐related issues. Originally named after its founders, our name was changed to RMC Water and Environment in 2005 to better reflect the company’s focus. Since then, RMC has merged with several specialized companies, steadily expanding our expertise in water quality studies and NPDES permitting, hydrologic modeling, integrated resource management, and computer information systems.



RMC Water and Environment wants your professional experience with us to be rewarding and challenging. The environment is relaxed yet professional, where each employee comes to work knowing they are a key piece of RMC’s success. We know that our people set us apart, so we continually invest in their development and empower them to make decisions for the benefit of our clients and our company. We provide competitive compensation and benefits, attractive office locations, opportunities for career growth, and rewards for longevity.
