Basic infrastructure in Khonsa covers the essential needs of a district headquarters. Electricity is supplied by the Department of Power, Arunachal Pradesh; while coverage is widespread, the town experiences occasional power outages, particularly during the monsoon when lines are damaged by storms or falling trees.
Water supply is managed by the Public Health Engineering (PHE) department, which taps into natural mountain springs and rivers to distribute piped water to the colonies. Telecommunications and internet connectivity have improved significantly in recent years, with providers like BSNL, Airtel, and Jio offering mobile networks and 4G services, though broadband penetration remains limited and speeds can fluctuate due to the remote terrain.
