 Dewan Amar Nath Nanda (B.A., M.I.E.) was a highly distinguished civil and sanitary engineer in British India who served as the Sanitary Engineer to the Government of the Punjab during the 1920s and 1930s. He holds a significant place in the history of Indian engineering as a pioneer of public health infrastructure, municipal drainage, and early cooperative urban planning in the region. Throughout the 1920s, he rose to the peak of the Public Works Department (PWD) Sanitary Branch, frequently officiating and ultimately serving as the head Sanitary Engineer for the Punjab region. He oversaw extensive waterworks and regional drainage programs across major municipalities like Lahore and Multan. Dewan Amar Nath Nanda was one of the core foundational figures behind the creation of Lahore's famous Co-operative Model Town. In the early 1920s, he backed the visionary cooperative housing initiative alongside legendary engineer Sir Ganga Ram, facilitating the acquisition and engineering layout of what would become a model garden-suburb for the Indian middle class.

He was an influential, active council member and Vice-President of the historic Punjab Engineering Congress (established in 1912) throughout the 1930s, working alongside iconic Indian engineers like Rai Bahadur Ajudhia Nath Khosla. He served as a senior corporate member and leader within the Institution of Engineers (India), taking part in critical annual governance meetings shaping national engineering ethics and fee guidelines in the early 20th century. 

 Beyond Punjab, his engineering expertise was sought after by the princely state of Jammu, Kashmir, and Rajputana. He is credited with conceiving the first major modern water supply scheme for Jaipur. He designed the 110-kilometer-long pipeline from the Ramgarh Dam to Jaipur City. The project was completed under his guidelines and inaugurated by Viceroy Lord Irwin in 1931.

Later in life, his administrative and technical acumen led to his appointment to the high-level Delhi Improvement Trust Enquiry Committee. He worked closely alongside national figures like B. Shiva Rao to reform the chaotic post-partition urban development of New Delhi until his death in late 1950. He passed away on October 26, 1950
