Z-Tech (India) started life in 1994 as a civil construction firm building retaining walls, but it has since reinvented itself as a “creative urban rejuvenator” - a company that now designs, builds and operates immersive public parks from upcycled waste, treats industrial wastewater with proprietary technology, and still anchors the ground under highways and shipyards. The recurring pattern is a deliberate pivot from one-off EPC contracts toward annuity-like public-private partnerships: the company finds a government body with land and a mandate, brings the design and operational know-how, and then earns a share of the ticket money for two decades, using the cash flows of its older infrastructure business to fund the shift.
Business segments
Three engines at different stages - a creative-park platform generating recurring consumer revenue, a legacy geo-technical EPC business that still carries the order book, and a small but proprietary industrial-wastewater unit being repositioned for growth - each built with the capabilities of the one before.
1. ZingPark: where the group’s recurring revenue comes from
The company designs and operates themed public parks on government land under 20-year revenue-sharing contracts, collecting a cut of every ticket, snack and event sold - an infrastructure business that behaves like a consumer franchise.
- Land and capex provided by the government - municipal corporations and landowning authorities supply the site and fund the majority of capex, while Z-Tech contributes a minority share to keep “skin in the game,” resulting in an asset-light balance sheet and low depreciation.
- Waste-to-art is the signature and the moat - parks are populated with sculptures built from upcycled and reclaimed scrap, a skill that requires specialised visualisation and reconstruction, making the company the largest employer of artists and artisans in India and giving each park a distinctive, hard-to-replicate identity.
- Affordability drives the flywheel - ticket prices are kept low to maximise footfall, which in turn generates robust cash flows from food, events and retail, builds civic goodwill, and leads to more government mandates, which further improves scale and margins.
- Demand exists far beyond metro cities - parks in smaller Tier-3 cities such as Khurja draw 25,000-30,000 visitors per month, and the company sees “no meaningful competition” in a market it estimates at roughly ₹28,800 crores of total addressable opportunity.
2. Terra: the geo-technical backbone that built the company
A quarter-century-old EPC business that stabilises soil, reinforces slopes and builds retaining walls for highways, shipyards and mining projects - generating project-based revenue without taking asset or capex risk.
- Pure EPC and O&M, no balance-sheet exposure - the company refrains from direct investment in the assets it builds, limiting its role to engineering, procurement and construction, which keeps working-capital intensity low and revenues stable.
- The retaining-wall specialist for national infrastructure - over 300 completed projects span applications from reinforced-soil walls on the Bharatmala highway programme to ground improvement at the Kochi shipyard, with a client list that includes L&T, Tata Projects, Dilip Buildcon and Afcons.
- Heavy machinery deployed for the next leg - the company has purchased significant site equipment for mining stabilisation work, signalling a push into a new sub-segment within its existing geo-technical skill set.
3. Agua: the proprietary wastewater bet being repositioned for growth
A small industrial-wastewater unit built around acquired GEIST technology that recovers chemicals from factory effluent - currently EPC-driven, but being relocated and refocused toward higher-margin annuity contracts.
- Technology bought, not built in-house - the GEIST platform was acquired in 2020 and bundles freeze crystallisation, calcium-magnesium recovery and selective extraction processes that treat chemical-laden water and pull valuable compounds back out.
- Serves the chlor-alkali industry today - customers such as Grasim, GACL and Navin Fluorine use the systems to recover acetic acid, sodium sulphate and other chemicals, though the recovered material is currently handed back to the client rather than sold by Z-Tech because the contracts are EPC-based.
- A second water brand tackles sewage - the “GRACE” platform uses bio-filters, modular packaged STPs and nano-bubble technology for sewage recycling and lake rejuvenation, with government bodies and large real-estate developers as customers.
- Moving to Vadodara to move up the margin curve - the Agua industrial wastewater treatment business is being repositioned from Goa to Vadodara to drive faster customer access and higher-margin growth, while the company aims to advance wastewater solutions through Build-Own-Operate models as a forward-looking aspiration.
Group structure and partners
Z-Tech is a single listed entity with a concentrated promoter holding, no operating subsidiaries, and a recent acquisition that adds in-house water-rejuvenation technology.
- In November 2025, Z-Tech agreed to acquire a 76% stake in Grace Green Infra, a firm that brings government-certified vermi-filtration and modular STP technology - including systems certified by the Ministry of Jal Shakti and IIT Bhubaneswar that consume up to 80% less power than conventional plants - along with an unexecuted order book of roughly ₹22 crore.
- The board is evaluating a strategic separation of the park and infrastructure businesses to sharpen focus, and has raised capital through a preferential allotment of equity shares to fund expansion.
