Public utilities in Khonsa are managed by the Arunachal Pradesh state government departments, adapted to the challenges of its hilly terrain.
* **Electricity:** Supplied and maintained by the Department of Power, Government of Arunachal Pradesh. While historically subject to transmission challenges, rural electrification and grid stability have improved significantly. * **Water:** The Public Health Engineering Department (PHED) manages the water supply, primarily sourcing water from pristine mountain streams and springs which is then treated and distributed. * **Waste Management:** The Urban Development and Housing Department oversees local municipal solid waste, with an increasing focus on community-led sanitation drives and proper disposal to protect the sensitive hill environment. * **Telecommunications:** BSNL and major private operators (like Airtel and Jio) provide cellular and internet connectivity, though weather and terrain can occasionally disrupt signals.
