RE-ADVERT: TERMS OF REFERENCE (TOR) FOR CONSULTANCY FOR WATER SUPPLY SYSTEM DESIGN IN DHOBLEY, LUUQ TOWN, AND KISMAYO IN JUBALAND, SOMALIA
1.1 About Norwegian Refugee Council and the Project
Norwegian Refugee Council (NRC) has been present in Somalia since early 2006. Over these years, the Norwegian Refugee Council (NRC) has demonstrated a regional competence and expertise in working with displaced populations with programs in Food Security, Education, Water and Sanitation, Shelter, Information Counselling and Legal Assistance. Since 2013 NRC has become one of the leading actors in Implementing resilience programs in Somalia.
In South Central Somalia, NRC is implementing a resilience programme funded by DFID-UK through the Building Resilient Communities in Somalia (BRCiSII) consortium. The resilience program is intended to contribute to resilience of the target communities to shocks of drought, flood, conflict and diseases.
As part of the resilience program in Jubaland State, NRC intends to support the communities of Dhobley (Degaday and Tuulobarwaqo settlements), Luuq town, and Kismayo (Yontoy Settlement) through establishment of sustainable water supply Systems for domestic and productive use. It is envisaged that the intervention is capable of improving the resilience of these target communities in a manner that enhances inter-community cohesion. NRC is therefore looking for a dynamic, well qualified and experienced consultant to undertake a detailed feasibility assessment for design of sustainable water supply for each of the target locations.
1.2 Purpose of the consultancy
The main objective of the consultancy is to undertake a detailed technical, socio-economic feasibility and Environmental Impact assessment to determine the most suitable water supply option for each of the target areas. The consultant will map out the available options, choose the most suitable one, prepare designs, develop Bills of Quantities and produce a report for the same.
2.0 DELIVERABLES/SCOPE OF WORK
The consultant will work closely with the community leaders and members, NRC project Staff in the 4 locations – Dhobley (Degaday and Tuulobarwaqo settlements), Luuq town, and Kismayo (Yontoy Settlement) to undertake the following assignments:
Undertake the assessment of holistic water needs for the target primary and secondary settlements within the area.
Identify suitable water sources (surface water and groundwater), confirm quality and quantity of water available and the technical feasibility for extraction.
Depending on the most technically and socio-economically feasible and sustainable option, the consultant will undertake detailed technical assessment including but not limited to hydrogeological surveys and or topographical profiling for earth dams as may be applicable.
Design the water supply systems for the primary and secondary settlements in general and advise on the technologies most appropriate for the local needs, institutional capacity, environment, sustainability, and operation and maintenance capacities,
Design water infrastructure with transmission main including pipe trenching and laying with necessary accessories, pumping equipment, power supply, household/communal water points, livestock watering and storage capacity.
While designing and adopting particular technology, consideration should be given for the life-cycle costs of the proposed systems, the financial and technical capacities of the respective local communities and water management committees to operate and maintain proposed system. Depending on the local management
capacity, the consultant should consider the option of a Private Public Partnership management system and provide guidance on the same.
Prepare the detailed technical designs/construction drawings, technical specifications, bills of quantities and cost estimates.
Be available for technical support, undertake field visits etc., during implementation if required.
The Consultant is requested to respond to design queries, if any, after the completion of the assignment. The expected maximum turnaround time for such queries is 10 days. If design queries cannot be sufficiently clarified through phone or email, the Consultant will be required to come in person and any expense incurred in the process shall be borne by NRC for trips not exceeding two during the whole implementation period.
3.0 PROCESS AND TIMELINE
The assignment will involve consultations with all the NRC, Local authorities of the target locations and the existing Community structures at the target settlements.
The consultant to be identified for the assignment is expected to provide his/her own computer and relevant software/ hydrogeological survey equipment and tools and products for the assignment.
The exercise is expected to commence as soon as a possible and be completed within 21 days after start.
NRC will provide: transport from and to target villages- for site visits, administrative support
4.1 Hydrogeological Survey (where applicable)
The Consultant is to carry out geophysical measurements within the study area using the ABEM Terrameter SAS 1000, which distinguishes between clays and fresh water by use of Induced Polarization (IP) measurements. Furthermore, Werner traverses may be carried out, at different spacings to map out possible buried faults.
The hydrogeological/geophysical investigations will be carried out according to a multi-step approach:
A desk study and data-acquisition: Review of existing data, topographical maps, satellite images(Landsat TM with 30 m resolution), existing studies and borehole site investigations in the area, geological reports and maps (if available), borehole and surface water records, etc.
Hydrogeological fieldwork: Detailed reconnaissance survey of project area. (GPS co-ordinates, water level measurements, TDS and EC, condition, usage and performance where applicable) inspection of geological, geomorphological and structural characteristics of the investigated area; verification of existing data and findings.
Geophysical measurements: resistivity/IP profiling and vertical electrical/IP soundings.
Analysis of hydrogeological/geophysical data.
Compilation, analysis, and evaluation of the gathered data and information.
Site selection and reporting.
4.2 Expected outputs of the Hydrogeological survey
The expected output of this study shall be a Hydrogeological Investigations report detailing the following:
Description of the Geology and hydrogeology (including Inventory of boreholes and other water points) of the area of investigation;
Methods of investigations employed, including Geophysical Techniques
Detailed resistivity/IP survey (Wenner & VES) to delineate the productive aquifer- Consultant to carry out minimum of 500m Werner profiles and 4 VES soundings per site. Where there are existing boreholes, out of the 4 soundings, 1 shall be a control sounding undertaken at the nearest existing borehole.
Information on the aquifer potential; sustainable yield & Water quality;
Proposed drilling site, recommended maximum drilling depths, water strikes levels and aquifer types.
Proposed drilling method, and its applicability in the project area.
Mark 1 drilling site within each location with a concrete mark stone in presence of the NRC staff, the settlement leaders and district authority representative.
Collect GPS coordinates of the recommended sites and submit the same along with the final survey report.
4.3 Environmental impact assessment
Conduct a preliminary environmental impact assessment for the project which includes;
Identification of potential positive and negative environmental impact of the project
Propose activities that shall be undertaken during the project construction, operation and decommissioning phase to mitigate likely negative impacts
5.0 QUALIFICATIONS AND EXPERIENCE
The consultancy personnel shall comprise of a person or team of experts in engineering and hydrogeology. The following qualifications are required:
