The team said the river water appeared murky up to about 5-km before the Fourteen Falls. The team said they would also follow up on this case. However, there is a shallow well, approximately 26 feet below the surface level, at the Ndovu camp, whose water is used for other uses and not preferred for drinking as it is salty.Īt Dwa Estate Ltd, a facility dealing with the growth and processing of sisal products, the team found a huge heap of waste products.
This is also a case for follow up," the team said.Īt this site, the water appeared greenish and with significantly reduced quantity.Īt Galana Kulalu Food Security Project, the Galana river is canalised through an unlined 2-km channel to the water intake chambers from where it is pumped and passed through the filtration units for use on crops and livestock. "The prerequisite Nema licence and WRA authorisation could not be produced by the contractor at the site. Williams Ltd as the contractor for the National Irrigation Authority as the proponent. The dam construction work was in progress.Īpproximately 20-km downstream of Thwake Dam, there was another construction site overseen by G.L. The fourth phase will be the development of the irrigation component. Phase two will involve the installation of a hydropower generation plant while phase three comprises the installation of water supply, sanitation and waste water infrastructure. Phase one, which is ongoing, involves the construction of an 87-metre-high dam wall with 688 million cubic metre storage capacity. The four-phase Thwake Dam is expected to change the lives of 1.3 million residents of Makueni, Kitui and Machakos counties. The two rivers is where water for Thwake Dam will be harnessed from. They found out that while Athi River has water, Thwake River was dry. The team proceeded to Thwake Dam, which is located about 500 metres downstream of rivers Athi and Thwake. The quality of water at the site, however, appeared visibly good. The team said the site is a case for further follow up. The self-cleansing is due to natural water turbulence.Īpproximately 30 kilometres from Fourteen Falls is Kalawa area, where there was a construction site – probably for water abstractions. The major sites included Fourteen Falls downstream in Kilimambogo town on the slopes of Ol Donyo Sabuk National Park, Thwake Dam, National Irrigation Authority water works construction site and Galana Kulalu project.Īt Fourteen Falls, which is used as a water sport, tourist and recreational site, the team found out that the site was self-cleansing and had improved water quality. It gets water from Ngong Hills, Ondiri Wetland, Kinale, Kieni from which major rivers – Mbagathi, Ngong, Nairobi, Mathare, Ruiru and Ndarugu – flow from.ĭuring the field visit, the team collected water samples for laboratory analyses from various sites. The focus was on Athi River, which is approximately 591km-long within the 37,750km2 Athi Basin. The multi-agency team comprises ministries of Environment, Water, Sanitation, Agriculture, Interior, Lands and Physical Planning, Devolution, Tourism and National Treasury.
Their mission was to get a general understanding and overview of water quality and pollution status in the basin and formulate integrated approaches through a multi-agency Cabinet team. The team was led by Environment CS Keriako Tobiko, Mamo and Water Resource Authority quality manager Fred Nyongesa.Īrmed with notebooks and equipment for sampling water, they boarded a chopper. On September 29, a team comprising officers from the Environment ministry, Nema and Water Resource Authority went on a fact-finding mission to Athi Sabaki basin. The remarks followed a September visit to the basin by a multi-agency team He said enforcement action would be undertaken by Nema's 50 environmental inspectors deployed along Sabaki to ensure all discharge points are stopped. We also have a compliance assistance programme to help companies comply," Mamo said. "Those industries without effluent treatment discharge plants will be closed. National Environment Management Authority director-general Mamo Mamo said most polluters are industries along Athi River. The environment regulator has warned industries polluting the Athi Sabaki basin in Machakos county that they will be closed.
