Residents of Nairobi will from next week get less supply of clean water following low levels of water at Ndakaini Dam.

Water Cabinet Secretary Eugene Wamalwa says supply of water to city dwellers will be reduced by one day from the previous schedule which had been released by Nairobi Water Company.

Speaking in Ndakaini dam on Wednesday when he visited the dam to assess water levels, Wamalwa said the water at the dam has gone down to 41.5 per cent. He was accompanied by his environment counterpart Prof. Judi Wakhungu.

He noted that the areas in Nairobi which were getting water three days weekly will from early next week get water for two days.

The CS explained that the available water will be properly managed to ensure Nairobi continues to access the commodity in minimal quantities till April when long rains are expected.

Wamalwa said the government has set aside Sh9 billion to support measures earmarked to mitigate water shortage not only in Nairobi but in other affected parts of the country.

In Nairobi, the CS said, the money will be used to rehabilitate non-functional boreholes to support more supply of water.

The money will also facilitate supply of the commodity in arid areas including parts of north eastern region.

Ndakaini dam which is the main source of water for the city dwellers has been supplying Nairobi with700 million litres of water per day in the past, but currently the supply has gone down to 500 million litres.

The CS said other dams supplying water to Nairobi including Ruiru and Sasamua dams have not been affected by the current drought, but he downplayed their capacity to adequately supply the city with the much needed water.

“We want to urge residents of Nairobi and its environs to prudently use the available water and desist from washing vehicles with clean water meant for domestic use,” said Wamalwa.

About the Northern water collector tunnel, he said 20 per cent of the construction is over, adding that the project is expected to be fully done in June 2018.

“When the water tunnel is finally completed, the supply of water to the city will be greatly increased and we are hoping by next year the project will functional,” he observed.

On her part, Professor Wakhungu said rehabilitation of Aberdare forest which is main catchment area of the rivers supplying the dam with water was also on course.

“We are fencing the forest to prevent intruders and we have also embarked on planting of trees to conserve the catchment area,” she added.
