Water/Wastewater Project Manager
Washington, DC | Full-Time | $65–$90/hour
Orion Group are delighted to be retained by a leading, award-winning civil engineering and program management consultancy headquartered in Washington, DC. This firm is widely respected for delivering innovative, high-quality solutions in transportation, water/wastewater, and major infrastructure programs.
This position is a unique opportunity to sit directly inside the end client’s integrated program office, where our partner firm operates as a trusted subcontract consultant supporting some of the region’s most critical water infrastructure initiatives. You will play a key role in leading Potomac Interceptor Sewer Pipeline projects and shaping the resilience of the region’s water systems.
Why This Opportunity Stands Out
Our role in supporting diversity and inclusion
As an international workforce business, we are committed to sourcing personnel that reflects the diversity and values of our client base but also that of Orion Group. We welcome the wide range of experiences and viewpoints that potential workers bring to our business and our clients, including those based on nationality, gender, culture, educational and professional backgrounds, race, ethnicity, sexual orientation, gender identity and expression, disability, and age differences, job classification and religion. In our inclusive workplace, regardless of your employment status as staff or contract, everyone is assured the right of equitable, fair and respectful treatment.
