Nairobi River Restoration Program


Nairobi River Restoration Program


WRA as the Lead Agency in water resources management is mandated by the Water Act 2002 Section 8(1), among other tasks to:  regulate and protect water resources from adverse impacts; manage and protect water catchments; liaise with stakeholders for the better regulation and management of water resources. The Authority has made this possible through various Integrated Water Resources Management (IWRM) approaches, which involve multi-faceted interventions to address the myriad of issues and challenges in water resources.  The Authority has been working closely with the various stakeholder groups including Water Resource Users Associations (WRUAs), Private Sector, County Governments, NGOs, Academia and Public Sector Agencies

In a bid to rehabilitate, restore and sustainably manage water resources within the Athi River basin, which includes Nairobi River and its tributaries, WRMA developed the Athi River Restoration Programme (ARRP) which is a capital project planned to be implemented in five years at an estimated cost of Kenya Shillings 2.5 billion.

Following the strategic importance of Nairobi River Basin, WRMA intends to spearhead the rehabilitation and restoration efforts of Nairobi River in the same vein as the Athi River Restoration programme. Accordingly, WRMA in collaboration with the Ministry will endeavor to mobilize the needed resources towards the implementation of this programme. In this regard, the Ministry requested expert assistance from the US Government for this important initiative. The US Water Partnership has already committed to support by engaging two consultants to work with the Government of Kenya.

The Nairobi River Basin comprises of 3 main rivers: Ngong, Nairobi and Mathare. The rivers join east of Nairobi and meet River Athi, eventually flowing to the Indian Ocean.  Other tributaries of Nairobi River Basin include; Kamiti river (Gathara-ini), Rui Ruaka, Karura Ruiru and Kirichwa.

The rivers are mostly narrow and highly polluted. Currently about 56 percent of the city residents live in 46 highly congested informal  and middle class settlements mainly located along the Nairobi River banks. The Rivers are polluted with uncollected garbage; human waste from informal settlements; industrial wastes in the form of gaseous emissions, liquid effluents, agro-chemicals, petro-chemicals, metals and over-flowing sewers.

The most worrying trend is the industrial and medical waste harboring toxic chemicals and heavy metals that end up in the Indian Ocean. The domestic and international tourism sectors are not spared with visitors getting harboring concerns about the safety of their favorite sea foods.

The Authority intends to carry out the following interventions in a bid to rehabilitate the Nairobi River:
