Leadership
Founder – Decon Engineers
B.E. Mechanical Engineering
In 1986, Mr. Lalji Dubey founded Decon Engineers with a vision to build an engineering company based on technical excellence, integrity and long-term client relationships.
His dedication to quality workmanship and ethical business practices laid the foundation for what has evolved into Decon Infratech today.
The values established by our founder continue to guide every project we undertake across Fire Fighting, MEP, Plumbing, STP and WTP engineering solutions.
"At Decon Infratech, we believe that infrastructure is more than steel and concrete — it is the foundation of safety, progress, and trust. Carrying forward the legacy my father, Mr. Lalji Dubey, established in 1986, our mission is to deliver MEP, Firefighting, STP and WTP solutions that meet the highest standards of quality, compliance, and reliability."
"Every project we undertake is a commitment — to our clients, to the communities we serve, and to the safety of every life that depends on our systems. With a dedicated team, modern engineering practices, and an unwavering focus on integrity, we continue to build infrastructure that stands the test of time."
"I sincerely thank our clients, partners, and team members for their continued trust as we move forward together towards a safer and more sustainable future."
