Our Promise

Our Vision

Engineering for tomorrow’s water infrastructure.

Our Mission

With an unwavering commitment to the water environment, we will continue to lead with innovation and ingenuity to help utility owners meet their level of service goals.

Our Values

RJN embodies an ownership culture, passionate about the environment, committed to community, and devoted to the welfare of its employees.

Safety is our number one priority for our staff and the communities where we work

Follow OSHA Safety Standards

All our field staff are required to complete OSHA safety training, learn high-traffic work zone plans, confined space entry protocols and demonstrate proficiency using protective gear.

Safety Planning is Required

Every major project requires a health and safety plan as dictated by our corporate HS policies. Examples of the plan components include manhole full-descent with an entrant rescue plan and on-site incident documentation.

Safety First! Practices

Working in underground infrastructure can be hazardous. We know when entering sewer systems, confined space entry, traffic control, and gas protection are critical for our crews and community members. 

Third-Party Safety Audits

Routine third-party audits provide extra assurances that our crews are knowledgeable on best safety practices, and the local community is safe when we are working in their neighborhoods.
