B. Objectives of the technical assessments
The main objective of this consultancy is to carry out detailed surveys jointly with the stakeholders to assess the technical feasibility of:
- Construction of water supply infrastructure in two target communities;
- Construction of additional infrastructure for the 2 communities where two shallow wells have already been identified.
From the findings of these assessments the Consultant should be in a position to design improved multi use water supply distribution system, and identify where new elevated storage tanks, reticulation piping from the mains supply to the storage tanks, collect relevant monitoring baseline data that shall be used for monitoring and evaluation during and after project implementation.
C. Expected results
Using participatory approaches, the technical assessment will deliver a report covering but not limited to the following for each of the sites:
- Technical Assessments for the four (4No.) proposed water sources targeted for construction of the basic water supply infrastructure preparation of designs and cost estimates. The Consultant shall focus on:
· An assessment of identified shallow wells- requisite technical details - location, year excavated, depth, construction details, initial and current yields, water quality, static water level, pumping water level, shallow well protection, general shallow well condition etc;
· An assessment of the proposed pumping equipment (pump, power supply source, control panels etc) – type / model, year installed, rated capacities, current condition etc;
· An assessment of the water distribution system (storage tanks / reservoirs, piping system, public kiosks, livestock troughs) – description of characteristics as relevant - type, volume / capacity, materials, numbers (how many), length, size, year installed, condition etc as appropriate;
· An assessment of water supply, usage and demand, including seasonal fluctuations – estimated demand (both human and livestock), current supply, main water uses, possibility to improve water availability and access for both livestock and human use;
· An assessment of current capacities in administration, operation and maintenance of the mini water supply system by the beneficiaries – including financial management, cost recovery or water tariff structures, access to necessary spares and technical support, availability of tools and equipments for maintenance (spanners, die stocks etc), governance structures and their effectiveness, existence of rules / by-laws, competence of the water committees, capacity building needs etc;
· An assessment of access to the supply by vulnerable groups – factors constraining access to water supply by vulnerable groups, how these factors are being mitigated and how this can be improved further.
· Analysis of sustainability of the multi-use water supply system – analysis of factors that can influence sustainability – environmental impacts and mitigation measures, technological options, economic viability of operating the system (including water affordability), social cultural considerations, and management capacities;
· Preparation of the project layout designs – site plan, flow diagrams (line plan and section of the entire scheme showing sequence of operations;
· Preparation of the preliminary project cost estimates aggregating project and the community contributions.
The consultant will analyse the water resource potential, current utilisation of water and scope for further development. The rehabilitation / construction needs of the water supply infrastructure, and the OM capacity building needs for each of the water supply systems at the target camps.
D. Key Issues to be considered in undertaking the assignment
¨ To improve effectiveness and efficiency of the water supplies, the project is keen on assisting the target communities to repair/replace the defective pumping and power equipment. Use of renewable energy sources that are cheaper to operate and friendly to the environment such as solar shall be given preference;
¨ Test pumping groundwater facilities shall be very critical to determine sustainable yields and appropriate pumping equipment. The project prefers use of standard equipment whose spares parts and capacity to repair are locally available;
¨ During the feasibility assessment it shall be very critical to consider rehabilitation/construction of water systems with adequate yields, good quality and as well as the sustainability of the management systems;
¨ Where possible, rehabilitation / construction of storage tanks will enhance water security by providing storage. This is particularly important in remote locations where breakdown of pumping equipment can take several days to repair. The tanks should be covered to avoid contamination and the design should include a manhole and ladder to ease access during cleaning and maintenance. Elevated tank shall be preferred or construction of a ground-tank at a point of high elevation such that it allows establishment of gravity water supply system;
¨ It will be crucial to put into consideration use of heavy duty uPVC / PE pipes buried 0.5m below ground level for the distribution system while designing for repair and expansion of water supply reticulation network. Note that the GI pipes are prone to corrosion;
¨ Water kiosks will be rehabilitated / constructed to improve water access. To reduce chances of vandalism, water kiosks with taps operated from inside a lockable room will be constructed for the larger settlements. The design of the water kiosks should ensure taps are accessible to all users (including children), and each kiosk has a good drainage system. As per the SPHERE standards, each tap should serve not more than 250 persons, and the households at the settlement should have access to a kiosk within 500m.
¨ Livestock trough design should include an apron with a slope away from the trough. Troughs will be provided with outlet for cleaning purposes and good drainage. Trough height will depend on intended usage – 0.75 for camels, 0.5 for livestock and 0.25m for shoats.
E. Work plan
On the basis of the proposed time schedule outlined in the Terms of Reference, the Consultant will prepare work plan for the technical assessment study and include this in their offer, and report on the approach taken in the study report. The work plan should set out Consultants’ approach to the following activities;
· Fact finding / data collection /surveys required to achieve the study objectives and results;
· Identification and analysis of various technical options to achieve the study objective and results;
· Planned consultation meetings with decision makers / stakeholders to assess the situation and identify the preferred technical solutions;
· Preparation of designs and cost estimates for the proposed solutions;
