The reconstruction works at Sasumua Dam have been completed raising hopes  that the perennial water shortages of water in Nairobi will ease. The dam spillway was badly damaged by floods in 1999 and again in 2003 and has been under reconstruction since 2008. The cost of the reconstruction project was Sh1.8 billion.

 

The dam comes under the jurisdiction of Athi River Water Services Board  (ARWSB) who are planning an official commissioning in December.

 

Ndakiano Dam on the Thika River which was full to overflowing in February this year supplies 80 per cent of Nairobi water needs  which  stands at 750,000 cubic meters per day. Sasumua supplies 15 per cent and Ruiru  Dam and Kikuyu Springs supply 5 per cent. Eng David Stower, PS Water Ministry says the raised Sasumua will hold an extra 12 million cubic meters bringing the total dam capacity to 17 million cubic meters.

 

The larger part of Nairobi uses 525,888 cubic metres per day  and receives its water from Ndakiano while the rest of the city relies on Sasumua.

 

With Nairobi’s population climbing  beyond the five million mark  the ARWSB  Chief Executive Officer Eng. Lawrence Mwangi has had talks with Treasury, to have  the construction of  Maragwa and Ruiru (Gatamaiyu) dams started at an early date.
