Keller Associates competitors and assessment
Company assessmentDirect peers
- Carollo Engineers: National engineering firm specializing exclusively in water and wastewater treatment plant design for municipal clients. Directly comparable to Keller in core water/wastewater treatment expertise, including SBR, MBR, and advanced nutrient removal technologies, though larger in scale (~$700M+ revenue).
- Brown and Caldwell: Environmental engineering firm focused on water, wastewater, and remediation for municipal and industrial clients across the US. Directly comparable as a water/wastewater-focused consulting competitor with similar technology offerings and municipal go-to-market model.
- J-U-B Engineers: Multi-discipline civil engineering firm headquartered in Idaho with offices across the Western US, serving municipal, transportation, and water/wastewater clients. Closest comparable in scale (~250+ employees), regional focus (Idaho/PNW/Intermountain West), and service mix to Keller Associates.
- Parametrix: Pacific Northwest-based engineering, planning, and environmental sciences firm with strong municipal water/wastewater and transportation practices in Washington, Oregon, and Idaho. Direct competitor for municipal RFQ/RFP work across the same Western US geography.
- RH2 Engineering: Pacific Northwest civil and environmental engineering firm specializing in water, wastewater, and stormwater infrastructure for municipalities in Washington and Oregon. Direct competitor for mid-sized municipal water/wastewater RFQ/RFP work in the same Western US footprint.
Broad incumbents
- HDR Inc. Large global engineering, architecture, and consulting firm with a strong water practice serving municipal clients. Overlaps significantly with Keller in water/wastewater and transportation engineering, but operates as a much larger full-service incumbent with broader geographic reach.
- Stantec: Global engineering, architecture, and environmental consulting firm with deep water and municipal infrastructure practices in the US. Competes with Keller for municipal water/wastewater contracts, especially in larger jurisdictions, while offering broader services across geographies.
- Tetra Tech: Large engineering and consulting firm with a leading water and environmental practice. Competes with Keller in water/wastewater treatment, environmental compliance, and federal infrastructure work, with significantly greater scale and international footprint.
- GHD: Global engineering, architecture, and environmental consulting firm with water and municipal infrastructure practices active in the US. Comparable in offering water/wastewater and transportation engineering services to municipal clients, but with much broader geographic and capability reach.
- Jacobs Solutions: Global professional services firm with one of the largest water/wastewater engineering practices in North America. Competes for larger municipal programs and is increasingly active in smaller community work where Keller also bids, though its scale allows it to mobilize teams far beyond Keller's capacity.
