Project Updates

Chemususu Dam

















The dam is located in Baringo County, Koibatek District and has a capacity of 15 million cubic meters or 15 billion litres. Chemususu Dam discharges 35,000 cubic metres or 35 million litres of water per day. It was designed to serve at least 50% of Baringo County population which includes towns and various institutions within the County.


Soin-Koru Dam


The Soin-Koru Dam Development project is proposed to be located on the Nyando River in the vicinity of Muhoroni in the Western part of Kenya. It shall be 60km from Kisumu City and 5km upstream of Muhoroni town. The Dam will be located in Kisumu and Kericho counties.


Siyoi - Muruny Dam

















The proposed Muruny Dam is located near Kapsait Primary School at Murkokoi Center which is approximately 43km from Kapenguria Town. The site location is covered on SK Map 75/4 Cherangany at GPS coordinates 36 N 0761064 and UTM 0129350, elevation 2690 masl at the riverbed. The project area lies within the Rift Valley Drainage Basin. River Muruny emanates from Cherangany Hills and flows in a North Eastern direction before finally draining into Lake Turkana.


Kiserian Dam









Kiserian dam is located along Kiserian River about 2kms from Kiserian Township and will supply water to Kiserian, Ongata Rongai and parts of Ngong’ townships. The present (2010) total population of the area is about 124,000 people with a water demand of 8,450m3   per day. The 18m high dam will store 1.22Mm3 of water and supply 15,700m3  per day of water to the townships which will meet the future (2020) water demand.


Maruba Dam

















In June 2010, NWCPC finalized rehabilitation of Maruba dam by raising the height of the embankment wall and spillway by 6 m. This increased the dam’s storage capacity from 0.60 Million m3 to 2.45 Million m3.  Increase in storage volume has ensured increase in water supply to Machakos Town and its environs from 2,050 m3/day to 8,700m3/day.

Climate Action


The UN Climate Change Conference, hosted by the UK in partnership with Italy, will take place from 31 October to 12 November 2021 in the Scottish Event Campus (SEC) in Glasgow, UK. The summit will bring parties together to accelerate action towards the goals of the Paris Agreement and the UN Framework Convention on Climate Change.

During the previous conference held in Paris, governments agreed that mobilizing stronger and more ambitious climate action is urgently required to achieve the goals of the Paris Agreement.

The National Climate Change Action Plan 2018 – 2022 aims “to further Kenya’s sustainable development by providing mechanisms and measures to achieve low carbon climate resilient development and create a link with priority areas.” Under the Water Sector, the plan outlines various measures of enhancing resilience of the Blue Economy and water sector as follows:

  • Increase annual per capita water availability through the development of water infrastructure
  • Climate proof water harvesting and water storage infrastructure and improve flood control
  • Increase affordable water harvesting-based livelihood programs
  • Promote water efficiency (monitor, reduce, re-use, and recycle)
  • Improve access to good quality water
  • Improve climate resilience of coastal communities
  • Climate proof coastal infrastructure

The Sunday Nation carried a Climate Action pull-out on 1st of August, 2021 which focused on the water sector. The Cabinet Secretary Ministry of Water, Sanitation and Irrigation Sicily Kariuki, (Mrs.) EGH says the Ministry has aligned its operations with the National Climate Action Plan and is in the process of establishing a sector Climate and Green Economy Unit to handle matters climate change.

Why Climate Action matters to us

The opportunities for action could not have come at a better time than now when adverse effects of climate change have been felt world over. We have witnessed shifting weather patterns that have resulted in food insecurity, catastrophic flooding, desert locust outbreaks, rising sea levels and temperatures across the globe. We therefore have a major role to play in increasing access to safe and clean water while mitigating against floods and drought.

 Water Harvesting and Storage for climate change adaptation

We intend to increase water storage in the country by 148.6 million cubic meters and enhance sustainability of constructed water structures through operations and maintenance. Further, we shall protect lives and property from the effects of floods and drought by constructing and maintaining 70km of dykes, 125 small pans/dams and 203 boreholes by the year 2026 as per our strategic objectives.” CS. Sharon Obonyo- Ag. Chief Executive Officer.

Water Harvesting and Storage projects

The Authority has implemented various water harvesting and storage projects across the country ranging from large dams, medium and small dams and pans, boreholes and masonry tanks. Complete Large dams are Chemususu Dam in Baringo County, Kiserian Dam in Kajiado County and Kirandich Dam in Baringo County.               

Large dams at various stages of implementation

  • Siyoi Muruny’ Dam                    West Pokot County
  • Soin- Koru Dam                         Kericho and Kisumu Counties
  • Isiolo Dam (Nkutuk Elkinyang’)    Isiolo, Samburu & Laikipia Counties
  • Badasa Dam                               Marsabit County
  • Nyahururu Dam                         Nyandarua County
  • Upper Narok Dam                     Narok County
  • Londiani Dam                            Kericho County
  • Rumuruti Dam                           Laikipia County
  • Umaa Dam                                Kitui County
  • Bosto Dam                                Bomet County
  • Igembe North Water Supply         Meru County


Medium dam: Naku’etum (Peace) Dam; Turkana County- complete

Complete Rehabilitated Dams

  • Maruba Dam- Machakos County           
  • Kalundu Dam- Kitui County                 
  • Hohwe Dam-  Nyeri County

Small dams and pans:

The National Water Master Plan (NWMP) 2030 sets out plans to support the realization of Vision 2030 through the development of 17,860 small dams and water pans that will increase access by 893 Million m³; a significant water storage capacity.

The Authority; formerly National Water Conservation & Pipeline Corporation (NWCPC) has constructed over 1000 small dams and pans mainly in Arid and Semi-Arid Lands (ASALs) across the country. This has contributed tremendously to the increase in water storage by approximately 20 Million m³ serving about 1.5 million people and over two million domestic animals.

Flood Control

We have implemented various flood control projects in flood-prone areas most of which are ongoing. These are:

  • River Awach Tende in Homabay
  • River Sabwani in Trans- Nzoia 
  • River Kawalase in Turkana
  • Goda - Merti in Isiolo
  • River Kuja in Migori
  • River Nyando in Kisumu
  • River Kapkakwa in Elgeyo Marakwet
  • River Perkerra in Baringo
  • River Nzoia in Busia
  • Oloipito-Elmasharian check dam in Narok

Budalangi flood control; currently spearheaded by the Ministry of Water, Sanitation & Irrigation.


The Sustainable Development Goal number 13 on Climate Action calls on all of us to “Take urgent action to combat climate change and its impacts.”
