1 Strategic Water Resources Analysis Phase II Evaluation of scope for water saving options through re use of water and desalination in the Nile Basin Terms of Reference for in Individual Consultant

2 Terms of Reference for evaluation of water saving options through water re use and desalination 1. Background Studies carried out by NBI indicate that the Nile Basin is likely to face more and more shortage of water, which results in increased stress on the river system and potential tension among the riparian countries. With the financial and technical support from the EU BMZ project, the Nile SEC is currently undertaking studies to generate strategic options that shall contribute towards the dialogue on cooperative water resources management and development. A category of these options focus on enhancing the water supply through implementation of various measures including, among others, re use of water and desalination. The Nile SEC intends to employ the services of an individual consultant to develop potential scope for enhancing the water supply through re use and desalination. This document describes the preliminary scope of work for the study on developing the potential scope for re use of water and desalination. 2. Objective: The objective of the study is to develop quantified options (as scenarios) for re use of water and desalination in the Nile Basin. 3. Study approach The study shall be carried out based on existing data in the Nile Basin and other parts of water where the two measures, re use of water and desalination, are practically employed successfully and further projection of technical and economic parameters that define the technical and economic viability of the two measures. 4. Scope of work The scope of work shall include all necessary literature review, analytic work and consultation required to evaluate and generate scopes for application of re use and desalination in the Nile Basin countries. The specific scope of work shall include, but not limited to the following: Task 1: Inception (1 month, 15 man days) a) Carry out preliminary scanning of world wide experiences, approaches and technology parameters that define the scope and viability of water re use and desalination; b) Develop detailed methodology for the study and refined work plan. The detailed methodology shall, among others, include a system for classification and documentation of types of technologies, socioeconomic parameters and performance metrics, such as scope for covering existing water demands as a function of cost, for evaluating water re use and desalination as measures for enhancing water supply. The scope of re use of water shall, at a minimum, cover: industrial use, municipal use, re use of drainage water from irrigation fields.

3 The scope of desalination shall include brackish and saline water. c) Prepare and submit inception report; the inception report shall be finalized after incorporating the Client s comments Task 2: Document practices on water re use and desalination (2 months, 30 man days) a) Based on the classification approach and performance metrics developed in the inception phase, document in a Technical Background Document I current practices of water re use and desalination in the Nile Basin countries and other parts of the world. The document shall also cover issues indicated below: o Water re use: Key lessons learned, issues (water quality, legal, institutional constraints, acceptance, measures of success. etc), technologies available, trends, etc Desalination: key lessons learned, issues (water salinity, financial, economy of scale, legal, institutional constraints, etc), technologies available, trends, etc b) Present the findings in the Technical background Document I in a regional workshop to be organized by Nile SEC; improve the document incorporating feedbacks from the stakeholder group attending the workshop. c) After the workshop, prepare final versions of the Technical Background Document I and submit the same. Task 3: Develop scope and scenarios for water re use and desalination in the Nile Basin (2 months, 20 Man days) a) Based on the findings in Technical Background Document, develop technical, economic, and other criteria for successful implementation of water re use and desalination in major/key water sectors in the Nile Basin. b) For locations where water re use and desalination are practiced, explore measures for improving the gains made from these practices c) Based on the criteria identified above, identify geographic locations where the two measures can successfully implemented with quick and substantial gains in terms of water saving; d) Develop scope (e.g. volume of water re used, desalinated) for gains from these two measures as a function of capital and O and M costs for major locations identified above; e) Analyze implications of the successful implementation of water re use and desalination on standards for water quality of effluent discharges. This, in turn, shall be used to iterate on the overall economic and financial implications of proposed measures at the locations identified above.

4 f) Analyze if there are any transboundary water quality implications (minimum standards/norms for key water quality parameters) and propose policy recommendations; g) Develop up to 5 options on scope for water re use and desalination in the Nile Basin. These options shall be developed for a set of overall socio economic scenarios projected for 2050 for the Nile Basin countries. The specification of the option shall, among others, include the following: a. Contribution of the options towards meeting water demands (how much water) as a function of cost; b. Water use sectors to which the option contribute, i.e. Municipal and Industrial, Irrigation c. Likely tradeoffs, such as water quality implications d. Approximate estimate of capital investment needed to realize these options; h) Document and present the options developed in Technical Background Document II. i) Based on the findings in Technical Background Document II, develop two issue papers, one for water re use and the other on desalination, that synthesize the options for application of water re use and desalination in the Nile Basin. The Issue papers, besides describing the scope and options for water re use and desalination, shall also outline what key policy interventions (including incentive mechanisms) that need to be put in place to promote water re use and desalination as measures for enhancing the water supply. These papers shall be used as inputs for raising awareness and possible policy directives from NBI governance (Nile COM), hence, promote water re use and desalination as possible options for enhancing the water supply in the Nile Basin. 5.

5 Together with all data collected and compiled 4 Two Issue Papers Experiences and qualifications of the consultant The consultant shall have the following minimum qualifications and experiences: Education: advanced university degree (Minimum of MSc, PhD preferable) in environmental engineering. Water resources engineering or related fields from a recognized university. Specialized training on water re use and desalination technologies is an asset. Experiences: Minimum of 10 years experience in technical/analytic experience in developing engineering options for water re use for major water use sectors (Municipal, Industrial, Irrigation); Demonstrated experience in evaluation of technology and policy options for desalination of saline and brackish water for large scale use; Demonstrated experience in preparation of policy and regulatory frameworks for water re use and desalination; Experience in evaluation of economies of scale for water re use and desalination Excellent facilitation and inter personal skills; 7. Schedule This study is part of the second phase of the strategic water resources analysis, which is currently ongoing. Therefore, the schedule for this study shall be closely aligned to that of the on going analysis. Figure 1 below presents indicative timeline for execution of this study. At the beginning of the study, the client and the consultant shall develop a refined schedule to closely align the schedule of this study with that of the strategic water resources analysis.
