Overview of position

As part of the UK Government support Sudan’s efforts to move, where possible, to longer-term and more sustainable development, the Foreign and Commonwealth Office (FCDO) has supported our cliet to implement “Urban Water in Darfur” project. The project is aimed at increasing of the availability and reliability of water sources in the four state capital towns of Darfur in Sudan. The project output to date enabled access to clean drinking water for an estimated 400,000 people, in two states, and the project also supports improved water supply management in two further states. The project is jointly implemented by UNICEF and our client.

The UW4D project includes infrastructure expansion in two towns and master planning in four towns. This infrastructure component is substantively complete, and water is being provided to the target communities. Master plans in three volumes (Infrastructure, institutional and financial components) were completed in 2018 for el Fasher and Zalingei and will be updated in 2021. Master plans will be prepared in 2021 for Geneina and Nyala. The project also includes a capacity-building component.
This ToR relates primarily to the master planning, with some input to capacity building.

Role objectives

  1. Purpose and Scope of Assignment

The Pipe Network Hydraulic Analysis Consultant will be responsible for undertaking pipe network hydraulic design to feasibility stage for pipe networks in the target towns of El Fasher, Zalingei, Nyala & El Geneina.
Specific results to be achieved include:
Using approved and appropriate hydraulic analysis software:

  • For el Fasher
    • Updating of el Fasher hydraulic analysis to take account of new connections and non-design modifications, including reduced input volumes.
    • Assessment of the value and applicability of 18 raised tanks, currently included in the design, for long-term system operation given the closure of community standpipes.
    • Hydraulic design, to feasibility stage, of new sections as determined in master plan update.
    • Recommend appropriate zoning to improve management of the demand and supply areas, and to facilitate improved water measurement.
  • For Zalingei
    • Hydraulic design of new sections as determined in master plan update.
    • Recommend appropriate zoning to improve management of the demand and supply areas, and to facilitate improved water measurement.
  • For Nyala and Geneina
    • Hydraulic analysis of existing network and recommendation for changes / improvements to ensure hydraulic performance
    • Hydraulic design of new sections as determined in master plan update
    • Recommend appropriate zoning to improve management of the demand and supply areas, and to facilitate improved water measurement.

The consultant will:

  • Work closely with our client Darfur team. 
  • Understand the operation and management characteristics of the water networks, and the water allocation procedures in the four towns.
  • Review the hydraulic capacity of the existing transmission pipelines from the various water sources supplying the towns and recommend improvements to cater for medium- and longer-term growth.  In particular, consider replacing the numerous small diameter pipes with one (or more) larger diameter mains, to achieve hydraulic efficiency and to reduce pumping costs. 
  • To provide & train UWA technical and managers to decide additional service connections.
  1. Approach and Methodology

The Consultant may propose his/her own methodology, and tools (i.e., hydraulic modelling software) but AutoCAD suite is preferred. Undertaking the hydraulic analyses will require a review of the existing maps and plans, and relevant documentation from assessments and studies that have already taken place.  The Consultant will liaise with the project team to ensure appropriate format of survey data for input to the network model.

  1. Key Deliverables:

The Consultant is expected to deliver as per the scope of work listed under Section II of this TOR.
Deliverables are:

  1. Two-page Inception Report outlining the approach and methodology, issues and workplan. Comments on the scope of the Terms of Reference can be made at this stage, if variations to the ToR are requested – these must be specifically addressed in the Inception Report. The Inception Report shall also list and comment on the data needs, data availability, and the need for additional data collection or survey work to be undertaken.  A single Inception Report can be submitted addressing the needs of all four towns, within 1 weeks of commencing the assignment.
  2. Draft Hydraulic design with supporting (short) Assessment Reports (for each town).   This should detail the hydraulic characteristics of the pipe networks, the analyses undertaken, the modelling carried out, and the recommendations arising. Included will be recommendations on establishment of network zoning, for improved operation and water allocation, locations of valves and meters, and network additions and improvements. The Draft Report will also include the results of other analyses and investigations undertaken, e.g., pump station designs, pump sizing and recommendations, optimising of transmission mains to reduce pumping energy costs etc.  Details of model runs to be included in appendices. Digital mapping/outputs of model runs, showing pipe sizes, to be included where appropriate. Separate reports for each town.
  3. Consultation on findings with State Government, SWC and UWA staff. A separate workshop to be conducted in each town. 
  4. Training materials for non-technical managers on hydraulic consideration in system management.
  5. Training even for non-technical managers.
