The infrastructure of Daporijo is developing, tailored to the rugged realities of the Himalayas. Electricity is supplied by the state power department, heavily reliant on local micro-hydel projects and the regional grid. Power outages can occur, particularly during severe weather. Water supply is managed by the Public Health Engineering Department (PHED), which sources and treats water from pristine local mountain streams and the Subansiri River.
Telecommunications have improved significantly in recent years. Major cellular networks such as BSNL, Airtel, and Jio operate in the town, providing mobile connectivity and 4G internet. However, broadband penetration remains limited, and mobile network reliability can fluctuate due to the mountainous terrain and heavy cloud cover.
