Basic infrastructure in Tuensang covers electricity, water supply, and telecommunications, though reliability can be a challenge. Electricity is supplied by the Department of Power Nagaland, with occasional load shedding during peak seasons.
Water supply is managed by the Public Health Engineering Department (PHED) and relies heavily on piped spring water and reservoirs; however, many households also depend on private water harvesting or neighborhood springs. Telecommunications have improved significantly, with major providers like Jio, Airtel, and BSNL offering 4G mobile networks, though broadband internet penetration remains limited compared to mainland Indian cities.
