Public utilities in Diglipur are managed by the Andaman and Nicobar Administration.
* **Electricity**: Power is supplied by the Electricity Department. Diglipur benefits uniquely from the **Kalpong Hydroelectric Power Project** (the only hydro project in the A&N Islands) which generates 5.25 MW of power. This is supplemented by diesel generator powerhouses to ensure continuous supply. * **Water**: Piped drinking water is sourced from the Kalpong River and local reservoirs, treated, and distributed by the APWD. * **Telecommunications**: BSNL is the primary telecom and broadband provider. While internet connectivity has historically been slow, the laying of the Chennai-Andaman and Nicobar Islands (CANI) submarine optical fiber cable is progressively improving bandwidth. * **Waste Management**: Managed by local Panchayats. Efforts are ongoing to improve solid waste management and plastic disposal to protect the fragile island ecosystem.
