“Success at NJSEI goes beyond financial gains” - Dr. Uday Kelker

NJSEI has established itself as a prominent player in the water and wastewater industry, both nationally and internationally. The firm has served a distinguished clientele across India as well as internationally, showcasing a track record of technical excellence, superior quality, and exceptional service delivery.

This success has elevated NJSEI’s status, positioning it as a leading consulting firm offering water and wastewater consultancy services to clients worldwide. Dr. Kelker shares,

“To put it plainly, “success” for us means achieving our company’s goals and milestones. It’s not just about stepping in when things go awry; it’s about assisting our clients in getting closer to their objectives through meticulous planning, feasibility studies, diligent supervision, and effective contract management – especially in the realm of engineering. While financial rewards are certainly important, true success can’t be solely measured by financial gains. It also involves acknowledging the other crucial factors that have contributed to our triumph. We take immense pride in the appreciation received from our clients for our project deliverables and our consistent approach to solving their problems in an environmentally friendly and cost-effective manner.”
