Kenya: Fibre Network Protected From El Nino Rains

As Kenya prepares for the heavy rains (El Nino), visit this site Liquid Telecom has completed a two-month project to protect its network during the anticipated rains.

Liquid Telecom is the leading independent data, store voice and IP provider in Eastern, Central and Southern Africa.

It supplies fibre optic, satellite and international carrier services to Africa’s largest mobile network operators, ISPs, and financial institutions.

“We launched an intensive contingency project as soon as reports began to come through of particularly heavy rains ahead,” said Ben Roberts, CEO of Liquid Telecom Kenya.

“We are aware of the disruption signal failure can cause and have thus worked at three levels to ensure the best possible service through any storms and flooding ahead,” he added.

According to the Telecom, the company has protected its networks by ensuring all of its customers will switch data flows seamlessly in the event of a disruption.

It has additionally ensured instant power back up at all hub sites, and relocated fibre and equipment in high risk areas, in an exercise of assessment and relocation that has involved more than 100 field staff and contractors over recent weeks.

“The contingency measures fully cover the Nairobi east and west regions, western, central, and coastal regions,” Liquid Telecom Kenya’s Head of Field Operations & Maintenance Mr Fredrick Okello said.


The majority of Liquid Telecom’s fibre network – which includes the biggest independent data network in Kenya – is underground, running beside highways as a national backbone.

The standard depth of the fibre is over 1 meter, keeping it safe from most water. Modern-day fibre also benefits from advanced waterproof coatings. However, severe flooding can sometimes see splice enclosures (where stripped fibre is fused and sealed from contamination) fail to keep water away from the fibre.

This has seen the company relocate fibre cable from high risk areas, particularly those at risk from river flooding.

It has reinforced bridge attachments over the Nyali Bridge and the River Nzoia, Yala, Nyando, Sondu, Chania, and Voi, and also relocated cables away from construction sites, where the soil is disturbed and can more easily be washed away by flood waters.

Where soil erosion is a major risk, gabions, or earth supporting walls, have been built to protect the cable.

“In Muranga, where we are anticipating landslides, we have relocated the cable from the road construction vicinity where the soil has been weakened by the earth movers to other sections which are secure,” Mr Okello disclosed.
