Inframark operates 400+ municipal water and wastewater systems under long-term service contracts, steered by CEO Steve Meininger.
Inframark
Inframark traces its operating history to 1925, when it began managing water systems for small and mid-sized municipalities. The firm has since evolved into one of the larger outsourced water-infrastructure operators in the country, specializing in the day-to-day operations, maintenance, and capital renewal of treatment plants, collection systems, and distribution networks that deliver drinking water and process wastewater. Its client base is almost entirely public-sector — cities, counties, water authorities, and special-purpose districts — alongside a handful of industrial customers operating their own pretreatment or process-water systems. The firm deploys capital and operating expertise across three connected streams: long-term operations-and-maintenance contracts for municipal systems, design-build-operate projects for new or upgraded facilities, and energy-management services that optimize power consumption at treatment plants. Inframark does not own the underlying physical assets; it derives revenue from multi-year service agreements in which it assumes operational performance risk. Its footprint spans the Sun Belt and Mid-Atlantic, with dense contract clusters in Texas, Florida, and Pennsylvania. Known contracts include the operation of the Baldwin County water system in Alabama and a long-running partnership with the City of Delray Beach, Florida. Inframark operates a centralized technical-services group that supports field teams with engineering, regulatory compliance, and procurement, giving a mid-market firm the back-office depth of a larger utility. In January 2025, the firm announced that PPC Enterprises, a New York-based private equity group, had acquired a majority stake from earlier investor H.I.G. Capital, signaling a push to expand through both organic renewals and bolt-on acquisitions in adjacent water-service verticals. The structural differentiator is the firm's niche: regulated public contracts for non-discretionary services. Water systems require continuous operation by law, making Inframark's revenue base far stickier and less economically sensitive than that of an industrial contractor or engineering consultancy. Renewal rates on municipal O&M contracts in the water sector typically exceed 90%, a characteristic that underpins the firm's long-duration cash flows.

Frequently asked questions
Who runs investment and operational decisions at Inframark?
Steve Meininger has served as CEO since 2022, overseeing both the firm's contract operations business and its growth strategy. The senior team typically includes divisional presidents who manage regional P&Ls for the firm's water, wastewater, and energy services lines. Major capital-allocation decisions — including M&A and large project bids — rest with Meininger and the board, which following the January 2025 transaction includes representatives from majority-owner PPC Enterprises.
How does Inframark source new contracts?
The majority of new business comes through competitive municipal procurements — requests for proposals issued by cities, counties, and water authorities seeking to outsource system operations. Inframark also retains and re-bids existing contracts at high renewal rates, common in regulated water O&M. A secondary channel is private negotiation with industrial clients that need on-site water-treatment operations, though this is a smaller share of total revenue.
Does Inframark own the water assets it operates?
No. Inframark is an operations-and-maintenance provider, not an asset owner. The treatment plants, pipes, and pump stations remain the property of the municipal or industrial client. Inframark's role is to operate those assets to meet regulatory and performance standards under fee-based, long-term service agreements — a structure that keeps its balance sheet asset-light.
What types of infrastructure contracts does Inframark typically pursue?
The firm focuses on three deal types: long-term O&M contracts for existing municipal water and wastewater systems; design-build-operate (DBO) arrangements where it helps build and then operates a new or upgraded facility; and energy-management optimization contracts inside treatment plants. It does not pursue large-scale civil construction projects or transportation infrastructure, staying within the water-and-energy niche.
Which geographies does Inframark serve?
Inframark's operations are concentrated in the United States, with the densest contract portfolios in the Sun Belt — particularly Texas and Florida — and the Mid-Atlantic region including Pennsylvania and surrounding states. It does not have a material international presence, and its public-sector client base ties it closely to domestic municipal budgets and EPA-regulated water-quality standards.
