Every time a city turns on a tap, a treatment plant cleans its water, or a river is held back by a dam, there is a good chance a piece of Indore engineering is quietly doing its job. That engineering belongs to Jash Engineering Limited — a company that has spent more than seven decades building the gates, screens and valves that guard the water the world runs on.
Jash Engineering’s story begins in 1948 in Indore, Madhya Pradesh. From those beginnings, the company says, it has grown into one of the world’s most comprehensive makers of water-control equipment — with more than 15,000 gates in operation, installations in over 45 countries, and over 3,000 gates manufactured every single year.
The gates that hold back rivers
At the heart of the Jash story is its water control gates range: slide and penstock gates, open channel gates, weir gates and flap gates, made in cast iron, stainless steel, aluminium, carbon steel, FRP and HDPE, in sizes from 100 by 100 millimetres all the way to 4,000 by 6,000 millimetres. These are the giants that sit at water intakes, pumping stations, treatment plants, desalination plants and storm-water stations — opening, closing and holding back water exactly when they are told to.
Alongside them sits a second great family: heavy fabricated gates — roller gates, radial and crest gates, tainter gates, bonneted gates, mitre gates and butterfly gates — built for the most critical applications, where failure is simply not an option. The company says Jash and its American subsidiary Rodney Hunt together offer the most comprehensive range of water control gates in the world market.
Screening, valves and the science of clean water
But Jash does far more than gates. Its screening equipment — fine and coarse screens in stainless steel and super duplex — strains the solids out of wastewater before treatment begins, with over 300 screens manufactured every year. Its knife gate valves, made in sizes from 50 millimetres to 4,000 millimetres, isolate solid-liquid mixes in cement, steel, power, petrochemical and chemical plants, with over 5,000 valves manufactured every year.
Then there is the elegant side of the business: water hammer control valves that protect pumping mains and cross-country rising mains from destructive pressure surges, with over 7,000 valves in use; Archimedes screw pumps that lift storm water and wastewater with remarkable efficiency; hydropower screw generators that turn low river heads into clean power; and a full treatment-plant range of clarifiers, detritors, aerators, mixers and disc filters. It is a portfolio that follows water from the river to the tap and back again.

An Indian maker with a global footprint
What makes the Jash story so satisfying is its reach. The company says more than 60 percent of its revenue comes from supplying equipment to projects outside India, and with subsidiaries in the United States, the United Kingdom and Germany, its equipment now serves water infrastructure on four continents. Its gates and valves work in water and seawater intake systems, water and wastewater pumping stations and treatment plants, hydropower stations, and power, steel, cement, paper and pulp plants across the world.
That scale shows up in the numbers. The company reports consolidated revenue from operations of ₹735 crore in FY25, with profit after tax of ₹87 crore — a record year for a company that has compounded quietly, year after year, by doing one difficult thing extremely well.
For a company whose products almost never appear in a photograph — buried in pumping stations, hidden inside treatment plants, holding back rivers in the dark — Jash Engineering is a wonderful reminder of what Indian manufacturing does best: build the essential things, build them to last, and let the work speak for itself. From Indore to 45 countries, its gates keep opening, its screens keep turning, and the world’s water keeps flowing.
