What Slater Infrastructure Group does

Slater Infrastructure Group LLC is a privately held, woman- and minority-owned infrastructure services firm founded in 1997 by Jeanne Simkins Hollis (originally as Multi-Energy Group and rebranded to its current name in 2021). The firm delivers engineering, program management, construction management, and operations and maintenance services across water and wastewater, transportation, environmental, energy, and aviation infrastructure for U.S. government agencies, municipalities, and select private-sector clients including Veolia Water and major construction management primes.

Its core service portfolio includes water and wastewater O&M across 30+ facilities processing 385+ MGD, transportation construction and program management covering 3,000+ miles of roadwork and $2.5B in supervised construction, environmental and coal combustion residuals services, energy management for power utilities, and satellite-based infrastructure assessment delivered through a partnership with Utilis. The firm differentiates through DBE/WMBE certifications (GDOT, NMSDC) and through Slater Certified®, an AI-powered workforce development platform launched in 2025 featuring a proprietary generative AI tutor called G.A.I.L., with a Georgia Secretary of State-recognized 40-hour Wastewater Class 3 Operator Training course and a white-label offering for partner organizations.

Commercially, Slater Infrastructure Group operates a primarily project-based and multi-year professional services model with custom, quote-based pricing for government and enterprise clients, supplemented by subscription/recurring revenue from the Slater Certified® training platform. The go-to-market combines direct enterprise field sales targeting municipal water utilities, transportation authorities, and power utilities; prime/subcontractor relationships with firms such as Atlanta Construction Management Partners; and a self-serve/PLG motion through the Slater Certified platform, with multi-state field offices in Georgia, California, Mississippi, and North Carolina.

Scale indicators7 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• Arcadis: Global design, engineering, and management consulting firm with significant water and environmental infrastructure practices. Comparable to Slater in target verticals (water/wastewater, environmental, transportation) but operates at far greater scale across global markets.
• AECOM: Global infrastructure consulting firm providing water, transportation, aviation, and environmental services — directly overlapping Slater's full service portfolio. Advisory board member Rob Rivers led a $600M capital improvement program for Columbus Water Utility while at AECOM. The firm is both a peer and a potential prime-contractor relationship for Slater as a DBE subcontractor.
• Veolia Water Technologies & Solutions: Veolia operates one of the world's largest water and wastewater service platforms and is an explicit customer and partner of Slater. As a multinational utility operator with extensive municipal O&M contracts, Veolia is a direct competitor for the same RFPs Slater pursues and an incumbent the firm benchmarks against.
• Stantec: International engineering, architecture, and infrastructure consulting firm with strong North American water, environmental, and transportation practices. Overlaps directly with Slater's core municipal water/wastewater and transportation service lines.
• Jacobs Solutions: Major global infrastructure and water-services consulting firm with deep municipal water utility relationships and federal/state transportation contracts. Competes with Slater for the same municipal O&M and program management engagements and operates its own DBE-certified business units that can disintermediate smaller DBE peers.

Direct peers

• Tetra Tech: Engineering and consulting firm specializing in water, environment, and sustainable infrastructure — closely aligned with Slater's water/wastewater O&M and environmental services practices. Comparable in target customer (municipal/government utilities) and service delivery model.
• HRP Associates: Engineering, environmental, and infrastructure consulting firm specializing in site assessment, remediation, and water resources. Closely comparable in size, service portfolio mix, and target customer base (municipal/industrial water and environmental services).
• Burns & McDonnell: Employee-owned engineering, architecture, and construction firm with strong water, environmental, and aviation infrastructure practices. Featured in Slater's "Making Waves" series, indicating peer-level industry engagement. Competes for similar public-sector infrastructure pursuits.

Emerging players

• Rising Tide Water Professionals: Smaller water and wastewater operations consulting firm serving municipal clients with a focus on workforce solutions and O&M services. Comparable niche positioning to Slater in the water operations and certified-operator training market.
• Utilis: Satellite-based leak detection and infrastructure assessment technology provider; Slater is a channel partner in the Utilis USA Partner Program. While a partner rather than direct competitor, Utilis competes with the data-driven infrastructure assessment service line Slater has begun to offer its utility customers.
