RFP:Consultancy Services For Survey And Development Of Detailed Design For Tiniku Water Supply Scheme & Konon Gos Water Pan In North Horr


Survey and Development of Detailed Designs for Community Water Projects in North Horr Sub-County- Marsabit County

1.0 Introduction

Concern Worldwide is an Irish International humanitarian organization driven by the vision of ending extreme poverty whatever it takes. The organization has operated for over 50 years fighting poverty globally.In Kenya, Concern Worldwide has been in operation since 2002 and currently works with communities in five counties. In order to contribute to ending extreme poverty among ASAL communities, the organization focuses on four key sectors which include Livelihoods/WASH, Health and Nutrition , Education and Governance and Advocacy. Concern has been supporting communities in Marsabit since 2008 to date. Marsabit County suffers from perennial inadequate water access a situation attributed to the area’s geographical location in an arid context with no permanent surface water sources and frequent occurrence of drought limiting any meaningful ground water recharge and rainwater harvesting.

2.0 Project Background

Marsabit County has a population of 459,785 people. The main economic activity of the population is pastoralism with minority practicing agro-pastoralism in parts of Moyale and Marsabit Central. Livestock production contributes 80% of income in Pastoral livelihood zones, 16% rely on Agro pastoral activities and 3% rely on other livelihood activities such as formal employment/fishing along Lake Turkana.[1] The County faces water scarcity largely attributed to aridity and frequent drought occurrence affecting rainfall and ultimately replenishment of water resources. Only 46.4% of the population have access to safe water and just 42.9 % have access to safe sanitation.[2] The Water sources in the County are varied with 49% of population relying on boreholes, 19% on shallow wells, and 11% on water pans, 9% seasonal rivers and 5% springs among other sources.[3] Due to this perennial water scarcity, the County Government of Marsabit and partners have continually sought to support the water sector in its bid to avail adequate and safe water to its population.

Concern Worldwide in Kenya won a grant from DANIDA through the Government of Kenya’s Water Sector Trust Fund (WSTF) for the implementation of Sustainable Management and Access to Water and Sanitation in the ASALS Programme (SWASAP) in North Horr Sub-County. The integrated project aims to address gaps in Water Access, Sanitation and Water Resource Management among targeted communities in the Sub-county through improved water infrastructure and water resources management. The overarching goal of the programme is to contribute to increased community resilience and adaptation to climate change through sustainable, peaceful use of natural resources including improved access to water and sanitation services in the target ASAL Counties. Concern Worldwide in partnership with the County Government of Marsabit therefore seeks to contribute to improving the water and sanitation situation in the target locations. The specific interventions include rehabilitation and augmentation of water supply schemes in each of the three projects and enhancing rainwater harvesting through improved storage capacities of proposed water pans each of which is proposed to hold at least 30,000m3 of water.
