Nepal Telecom has absorbed approximately US$5.8 million (NPR88 million) in infrastructure damage after extreme flooding knocked 83 of the state-run operator's 120 mobile sites offline in three districts north of Kathmandu.

Information and Communications Minister Bikram Timilsina told Nepal's House of Representatives that "83 of Nepal Telecom's 120 sites were affected, with around 70% of the operator's sites taken offline," according to reporting in the Economic Times. The storms sit inside a broader flood event across South and Southeast Asia that has killed more than 1,400 people and left 5,000 more reported missing.

Where is the damage concentrated?

The three affected districts are Rasuwa, Nuwakot and Dhading — hill districts that host backbone routes running from Kathmandu toward the Tibet border and into central Nepal. Damage by category, as reported by the minister:

• 3 mobile towers completely destroyed; service now restored at the remaining 80 affected sites, with restored capacity supporting customers in adjoining areas
• 37.9 km of Nepal Telecom's 65.3 km of fibre in those districts damaged, of which 27.4 km has already been repaired
• 3 optical line terminals in Rasuwa and Nuwakot destroyed outright

The fibre loss is the most consequential line item. Backbone cuts in those districts normally cascade into mobile backhaul and fixed-line outages for hours or days at a stretch, because fibre routes in Nepal's hill terrain have limited redundancy.

How much has been restored?

Timilsina told MPs that the remaining 80 affected sites are back in service. Restoration crews have also re-spliced more than two-thirds of the damaged fibre — 27.4 km of the 37.9 km affected — leaving roughly 10.5 km still to repair. The three destroyed towers and three destroyed OLTs in Rasuwa and Nuwakot cannot be restored in place and will require full rebuild.

Why does the bill land at US$5.8 million?

The minister's NPR88 million damage figure breaks down into tower replacement, fibre reinstatement and OLT replacement, with site-access costs in flood-hit terrain a significant add-on. State-owned operators in South Asia typically carry tower insurance; buried fibre is usually uninsured, so a large share of the cable repair bill is expected to fall on the operator's parent ministry and, ultimately, the government budget.

What is the broader context?

The flood event sits inside a wider storm system affecting parts of South and Southeast Asia that has killed more than 1,400 people and left 5,000 reported missing. The scale of infrastructure loss in hill terrain is likely to push carriers to elevate fibre conduit, anchor tower foundations above historical flood lines and pre-stage cell-on-wheels units in vulnerable districts, though Nepal Telecom has not announced any hardening programme.

What happens next?

Nepal Telecom still needs to complete fibre repairs on roughly 10.5 km of cable and rebuild three towers plus three OLTs before the next active monsoon window. The minister gave no completion date. The US$5.8 million repair bill now sits with the Ministry of Communication and Information Technology, which has yet to indicate whether emergency funding or a supplementary budget request will be needed to clear it.
