Since 1986, on one simple standard

Indu Raj Associates was founded in Delhi in 1986 by Mukesh Kumar Sharma. What began with small contracting jobs has grown into a practice built around water: treatment plants, purification, filtration, pumping and the maintenance that follows handover.

Alongside the contracting work we run an established supply business, providing materials against rate contracts, purchase orders and tender awards. We also own and market Puretron, our brand of water purification products.

Much of our work is carried out inside government offices, defence and paramilitary establishments, institutional campuses and heritage estates. Access is controlled, timelines are fixed, and disruption to the people using the building is not acceptable. That constraint has shaped how the firm works more than anything else.

Our vision

To be the water engineering partner that government and institutional clients call first, trusted for dependable work, clean documentation and plants that still perform years after handover.

Our mission

To carry out every contract, however small, with the right materials, skilled people, safe practice and honest measurement, and to finish on the date we committed to.
