Bomet Integrated Development Programme Phase-II

Terms of Reference for Design of the Proposed Chebang’ang Water Supply Projectand Conducting an ESIA

Project Title: Bomet Integrated Development Programme Phase - II - Bomet County.

1.Introduction and back ground information

1.1Background

The Kenya Red Cross Society (KRCS) and the County Government of Bomet (CGB) are in the process of jointly implementing the Bomet Integrated Development Programme Phase II (BIDP-Phase II) and have entered into an agreement to jointly mobilize resources and implement the Projects within the programme. KRCS has submitted a proposal for funding with commitment from the Bomet County Government to provide additional funding.

The Design of Chebang’ang Water Supply Project will commence with funding from the CGB, and will help in mobilizing for more resources.

1.2Project Goal:

Improved health as a result of increased access to safe and reliablewater for domestic use for communities in Kimulot and Chepchabas Wards ofKonoin Sub County, Bomet County.

1.3Location:

Chebang’ang Water Supply Project is located in Kimulot Ward of Konoin Sub-County. The project area is located between Maramara and Kimari Tea Estates at the edge of South Western Mau Forest. The project is a gravity fed water supply scheme abstracting water from Kiptiget River which has got its catchment and tributaries originating from the Mau forest.

1.4Description of Project:

Chebang’ang Water Supply project was started in the year 1976, with the support fromEuropean Union (EU) and became operational in 1982 with the capacity to serve a population of approximately 5,000 people. The project has outlived its design life and over time, has undergone many repairs and extensions. Today, it performs below the required demand thus having populations of Chepchabas and Kimulot wards being underserved and water stressed. The system is owned and managed by a Community Based Water Management Committee who are entrusted to operate and manage the system. Despite their limited technical knowledge and resources, the Committee struggles to ensure constant supply to the community by making key decisions and actions to have the water supply run as smoothly as possible through routine maintenance, revenue collection, and customer communication.

The existing water supply system consists of a weir, a 7.7Km conveyance pipeline, various distribution pipelinesand storage tanks which supply raw water to its consumers. The production stands at approximately 500m3/day against current water demand of 4,000m3/day and an ultimate water demand of over 6,000m3/day based on the projections from KNBS 2009 population data. Also, the existing pipeline distribution system serves only a few villages and schools within Chebang’ang sub-location against a potential coverage for the entire Kimulot and Chepchabas Wards which a have a population of 54,011 people as per KNBS 2009 projections.

The proposed project will integrate a new intake, raw water pipeline, water treatment plant, expansion and rehabilitation of the distribution system so as to ensure that it provides safe water to consumers within a wider coverage area at an estimate cost of Ksh.250 million. The project has a potential to serve a wider geographical area reaching out to a population of 54,011 (current) people drawn from two Wards of Kimulot and Chepchabas and aprojected population of 92,022 people by 2039. This highlights the urgent need for augmentation of the water supply scheme to meet the current demand but also to be adaptable to serve a larger future population.

1.5Scope of Works

The overall scope of the assignment will be the design of water supply infrastructure which includes head-works, treatment plant, conveyance system, storage facilities, distribution network and communal water points. The treatment works will include Laboratory, Staff houses, Fencing, guard house, chemical store and mixing facilities, backwash system etc.

The specific tasks to be undertaken by the Consultant will be in two parts, part I(design & ESIA) and part II(supervision that will be awarded at a later date). These parts will include(but will not be) limited to the following:

Part I-Detailed Design

•Mapping of targeted beneficiaries and demand modeling; this will involve detailed population projections, and consumption requirements estimations in line with the code and industry practice.

•Detailed topographical survey for the Head-works, pipeline routes, treatment works area and storage tanks sites;

•Detailed Hydrological study of Kiptiget River and its catchment/source and obtain WRMA Permit;

•Water quality analysis;

•Conduct a detailed assessment for all the existing facilities that include intake works, piping, storage and other facilities to determine their status and weather they would be incorporated in the new design.

•Detailed design for rehabilitation and expansion of the head-works, pipeline, treatment works, and storage tank sites and all other facilities that will be required for the optimal performance of the water supply system.

•Detailed design for the new Water Supply System ( T-Works, Pipelines, Storage Tanks) and all other facilities that will be required for the optimal performance of the water supply system;

•Coming up with a sustainability model in terms of the number and qualification of staff required at different levels: revenue collection, water production, data collection and analysis, and Non-Revenue Water Management;

•Provide specifications and quantity required for laboratory equipment;

•Training of the LAB operators on the use of the LAB Equipment, data collection, analysis and reporting of the results, to include formulation and production of reporting tools required.

Environment Impact and social assessment

•Conducting an ESIA and obtain NEMA license;

(A full proposal should be provided and this will be undertaken concurrently with the design by the consulting team/consortium)

  • A detailed TOR is annexed

Part II- Construction supervision

•Construction supervision and contract management for the construction works to include ensuring that the Contractor Produces all the required As-Built Drawings within the required timeframe;

(This assignment is provisional at this stage and the consultant should project the scope of the assignment and provide for the staffing and other resources required. The proposed costing should be valid for the next 12 months so that upon completion of design the consultant many be engaged for this assignment)

  • A detailed TOR is annexed
  • The TOR may be revised if so need be once the final design has been concluded and there is evidence of a change in scope.

Note: The consultant will also advice the client on any land acquisition that is deemed necessary to ensure the success of project and avoid delays during construction.

In view of these, the Kenya Red Cross Society and the County Government of Bomet would like to procure Consultancy Services from registered and qualified consultingfirms toprepare detailed designs and tender documents including drawings for the implementation of the above Chebang’ang Water Supply Project as well as the ESIA and to provide a proposal for construction supervision.

The Consultant will also prepare Operation and Maintenance Manuals and build capacity of the relevant water facility management arms in the required O&M practice. These O&M guidelines should also demonstrate and articulate clearly the O&M requirements for the designed systems and show the projected lifetime costs associated to the facilities.

The Consultant will also assist the client and the Water Service Provider (WSP) during pre-handover period (not less than two months) to ensure that the operators and other staff understand, operate and maintain system according to the design standards.

1.6Pre-Proposal Site Visits
