Dibrugarh's infrastructure has seen significant upgrades in recent years. Electricity is supplied by the Assam Power Distribution Company Limited (APDCL). While power cuts were historically common, supply has become highly reliable.
Municipal water is drawn primarily from groundwater sources and distributed by the city, though many independent homes still rely on private borewells. The city is currently expanding its underground drainage and sewer systems to better manage the heavy monsoon rains and prevent urban flooding.
Telecommunications infrastructure is robust, with widespread 4G and growing 5G coverage provided by major national carriers like Jio, Airtel, and BSNL. High-speed fiber broadband is readily available across most residential and commercial neighborhoods.
