Five years since the Karimenu II dam was constructed the water body is now filled up following the ongoing heavy rains being experienced in various parts of the country including   Gatundu North constituency in Kiambu County where the dam is located.

The 59m high dam across Karimenu River is currently holding 26.5 billion litres of water with the excess of it flowing downstream areas using a self-regulating spillway built near the dam.

According to Engineer Joseph Kamau (pictured), the acting CEO in charge of Athi Water Works Development Agency, adequate flood control and drainage works measures have been put in place to mitigate against flooding and overflow of water to the downstream as the water is channelled into the Karimenu River via the spillway.

The filling of the dam, he said, speaks to the structural safety and strength of the water resource that is projected to benefit more than 1.1 million residents of Gatundu, Ruiru, Juja, and parts of Nairobi with a clean water supply.
