Ramky Infrastructure is an Indian civil-engineering company that spent its first three decades building the country’s water plants, highways and industrial parks, then spent the last one repairing its balance sheet - and has now emerged debt-free at the standalone level, ready to bid again. It was founded in 1994 as a contractor and later expanded into owning and operating the assets it built, running them through separate project companies under long-term government concessions. The recurring idea is that the same in-house execution team designs, builds and then often operates the asset, which means the company captures both the construction fee and the steady operating income that follows. # Business segments Three engines at different stages - a construction core that feeds two owner-operator platforms, one in water and one in industrial parks, with a legacy road asset still generating annuities. ## 1. EPC construction: the factory that builds everything else **The company earns fixed-price contracts from government bodies to design and build infrastructure, keeping most work in-house so it controls cost, schedule and quality.** - **One-stop shop for government clients** - it takes a project from detailed engineering through procurement to commissioning, working almost entirely for central and state government authorities across India. That is how it has built roughly 1.5 crore square feet of buildings so far, with another 1.5 crore under construction. - **In-house execution is the differentiator** - most works are done by its own teams rather than subcontracted, which gives it control over capital spending, timelines and operating costs; specialist expertise is brought in only when needed. The company believes its engineering and detailed-engineering capability sets it apart from competitors. - **Bidding only where the risk is priced** - past financial trouble came from taking on too many fixed-price government jobs without cost-escalation clauses, so the company now selects contracts only if they carry a reasonable margin and a cost-overrun clause. A formal risk process screens every bid for legal and contractual traps before the company commits. - **Commissioning is treated as a handover discipline** - on long-tenured water and sewage projects, the team aligns design, equipment choice and commissioning standards to the operational phase from day one, feeding operating experience back into future designs. That is how it turns a construction job into a lifecycle infrastructure business. ## 2. Water and wastewater: the first-mover platform **The company builds, owns and operates treatment plants and effluent systems under concessions that can run for 15 to 20 years, turning construction wins into long-term operating income.** - **Zero Liquid Discharge is a distinctive skill** - it runs Common Effluent Treatment Plants (CETPs) that treat industrial wastewater to ZLD standards, a capability few Indian infrastructure players can match. One of these, a 4 MLD plant in Pantnagar, serves more than 350 industries under a 30-year concession. - **It operates India’s largest SBR sewage plant** - the 320 MLD Nagole facility in Hyderabad uses Sequential Batch Reactor technology, which needs less land and power than conventional treatment. Through a subsidiary, it is building another five plants totalling 480 MLD along the Musi River, with three already commissioned and a 15-year O&M contract attached. - **Waste is a recurring revenue stream** - the company developed India’s first major hazardous-waste landfill and the Hyderabad Waste Management Project, and it now runs a carbon-neutral 2 MLD leachate treatment plant powered by its own 1 MW solar installation. It has also built waste-to-energy plants, including an 800 tonnes-per-day single-boiler facility in Dundigal that is already operating. - **New contracts keep the pipeline full** - it recently won a INR 2,085 Crore drinking-water transmission scheme under a hybrid annuity model with 10 years of O&M, and the board has approved acquiring another water and wastewater company to expand its footprint. ## 3. Industrial parks and urban solutions: the landlord-developer **The company creates large-scale industrial parks where it earns money from land leases, utility charges and maintenance fees over concession periods as long as 95 years.** - **A 2,400-acre pharma park was the blueprint** - through its joint venture with the Andhra Pradesh government, it developed Jawaharlal Nehru Pharmacity in Visakhapatnam, the largest sector-specific industrial park in India, complete with a CETP, roads, water supply and sanitation. The company held a 20-year sub-concession to operate and expand the park, which it called a “steadfast cornerstone” of future cash flow, before selling its 51% stake in March 2026 for INR 165.24 Crores. - **A 1,000-hectare life-sciences city is the next act** - awarded by Maharashtra’s industrial development corporation on a 95-year DBFOT concession, the Dighi Port project will generate revenue from land-lease premiums, development charges, maintenance fees and utility charges. Alongside it, the company also won a INR 1,401 Crore EPC-plus-O&M contract to build the park’s roads, drainage, power and water infrastructure. - **The operating role goes beyond construction** - in its industrial parks, the company supplies steam, treats and resells water, and maintains internal roads, turning the park into a utility-style business that earns fees for as long as the concession lasts. It recently commissioned end-to-end automation of effluent collection and disposal at Vizag Pharmacity, which it describes as the largest such system in the country. - **Urban solutions extend the logic to cities** - through subsidiaries, it builds and operates environmental infrastructure for sustainable communities, including a carbon-capture subsidiary and a unit that has signed MOUs with Bengaluru’s real-estate and apartment associations. ## 4. Transportation: the legacy annuity stream **A single mountain highway in Jammu & Kashmir generates annuity payments from the national highways authority, while other road assets have been handed back or merged into the parent.** - **The Srinagar-Banihal Expressway is the only road connecting the Kashmir Valley to the rest of India** - operated through a wholly owned subsidiary under a 20-year DBFOT concession from NHAI, the project has reached commercial operations and is now in the O&M phase. After being a non-performing asset for five years, the subsidiary settled its debts with lenders and is now securing fresh loans backed by future NHAI annuities. - **Other road projects have been wound down** - the Outer Ring Road project in Telangana and the Dehradun interstate bus terminal both completed their concession periods and were handed back to the authorities. Two other road subsidiaries have been merged into the parent company under an NCLT-sanctioned scheme, simplifying the group structure. # Group structure and partners **A flagship EPC company surrounded by project-specific subsidiaries, each created to isolate a single concession from the rest of the group.** - The parent company executes EPC contracts, while 16 subsidiaries and 8 unconsolidated joint ventures hold the developer projects, keeping each concession’s debt and risk ring-fenced. - Key subsidiaries include the Srinagar highway company, the Hyderabad sewage-treatment company, the Pantnagar effluent-treatment company, the Chennai biomining company, and the newly formed entities for the Dighi life-sciences park and the Godavari water-supply scheme. - The company’s customers are almost entirely government bodies - municipal corporations, water boards, the national highways authority and state industrial development corporations - which makes the order book public-sector by nature. - After fully repaying INR 3,859.81 Crores of restructured debt, the standalone entity exited its restructuring framework in July 2025 with nil term debt, and its working-capital facilities are now classified as regular and standard by lenders.
