EXPRESSION OF INTEREST (EOI) – Feasibility study on use of solar distillation at schools, in order to develop a sustainable approach to supply safe water to the schools in oPt.



Subject: Feasibility study on use of solar distillation at schools, in order to develop a sustainable approach to supply safe water to the schools in oPt.

Date of the EOI: 21 January, 2013

Closing Date of the EOI: 4 February, 2013

Although most schools are connected to water networks, availability of adequate quantity of water and its quality are not always assured. Salinity has been identified as a major problem in parts of Jordan Valley, in West Bank and over 90 per cent of Gaza. The lack of adequate supplies of safe drinking water at schools has forced the schools to buy water from private vendors, who are not regulated and therefore there is no assurances on the quality of water provided to the schools. Furthermore, such water supplied through tankers is costly and will be difficult to sustain by the schools.

In an effort to solve the problem of salinity, brackish water and sea water desalination plants have been installed. As a part of comprehensive regional desalination plant proposal of the Palestinian Water Authority, UNICEF has plans to install 6,000 m3/ day capacity sea water desalination plant. This UNICEF planned desalination plant will cover only part of the two of the five governorates in Gaza.

Therefore, it is important to explore sustainable low cost water treatment system such as solar distillation at the schools to provide drinking water to the students. This will be more sustainable compared to the water supplied by tankers.

Specific Tasks

The specific tasks to be accomplished by the Consultancy Firm/NGO should be as follows:                           

1.      A desk study

It should be carried out, collecting all data, maps, and review and evaluate the available documents and reports related to the solar distillation installed by various agencies in oPt. In addition the desk study must also include all the information and finding obtained during the field visits done to the schools in West Bank and Gaza.

2.      Detailed engineering Study and Survey

Upon the completion of the desk study, the Consultancy Firm/NGO will develop a conceptual preliminary design for all elements associated with the solar distillation of water for schools. Detailed engineering study must include the following:

  1. Technical Feasibility Study:

It should include reviewing the available data, collecting, reviewing and analysis of the field data to be used in the study of installation of the solar distillation units. Under the Technical Feasibility Study the Consultancy Firm/NGO will:

·         Present at least 3 different models to be considered in order to supply safe drinking water to the students in the schools.

·         Assess the production capacity of the models recommended (It must be understood as different  distillation units) to meet the drinking water requirements of the students;

·         Undertake a detailed financial analysis of the project elements, for each one of the models.

·         Assess location and space availability for the adequate production of safe water through solar distillation process;

·         Investigate raw water availability and re-mineralization of distilled water.

·         Evaluate the cost analysis provided for specific production cost of safe drinking water.

·         Water quality monitoring (Assurances)

4.      Analysis of Data, design and estimates

Based upon the above mentioned feasibility study the Consultancy Firm/NGO shall make the best use of their technical know-how and professional skill to arrive at and recommend the most cost effective sustainable alternative for the installation of the solar distillation units at schools and present this proposal to UNICEF. Once that UNICEF and the Consultancy firm/NGO agree that the presented alternative is the most suitable option, the Consultancy firm/NGO will develop a draft implementation plan.


5.      Draft of the Implementation Plan

The Consultancy firm/NGO will prepare an implementation plan in order to test the chosen alternative in 2 schools in Gaza and 2 schools of the Jordan Valley in West Bank, during year 2013 (Pilot experience).

This implementation plan must be clearly defined and include different aspect as:

·         Name of the  schools

·         Activities to be carried out previous the installation units, as well as during the process of testing the units. The timeline needs to be included.

·         Responsible persons or institutions involved during the testing process.

·         Monitoring and evaluation of the process

·         Budget for the testing process

·         Documentation of the experience.



In general terms, the methodology applied by the Consultancy Firm/NGO shall focus in the development of as sustainable model at school, using the solar distillation process in order to provide safe drinking water. Previous the presentation of the methodology, the Consultancy Firm/NGO will present a detailed work plan of the activities that will take place during the feasibility study. This work plan shall be presented one week after the date of signature of the contract.

This methodology must contemplate at least but not limited to, the following steps

·         Collection of primary information.

·         Collecting all data, maps, review and evaluate the available documents and reports related to the solar distillation process that could have been tested in the ground by institutions, agencies and NGO not only in oPt but also in the region. 

·         Interviews with institutions, agencies or NGO that have in some way worked in the oPt, using solar distillation process in their projects: questionnaires should be prepared by the Consultancy firm/NGO in order to obtain the information needed for the analysis.

·         In the case, that some experiences have been developed in the field, the Consultancy Firm/NGO will plan field visits.

·         At least 20 schools must be sampled, distributed between Jordan Valley and Gaza, in order to have a real understanding of features in schools, and especially in terms of availability of water as well as its quality.  A well understanding of the existing situation will be indeed a relevant and necessary aspect in order to determine the feasibility of using solar distillation in schools. For the schools that will be sampled, tools will be prepared by the Consultancy Firm/NGO, in order to obtain all the information that is relevant for the feasibility study.

During the feasibility study, the Consultancy Firm/NGO must report the progress of the study to UNICEF. It is recommended that during the first 3 weeks of the work, the consulting firm and UNICEF have weekly meetings in order to avoid misunderstandings among the parties.

Expected Deliverables

The Consultancy Firm/NGO shall submit a series of reports. All reports have to be produced and written in English, The Consultancy Firm/NGO shall submit three reports during the feasibility study, for each report is necessary to present an original plus two copies in addition to the electronic version.  In addition the Consultancy Firm/NGO shall provide an electronic version of all the required deliverables. The reporting shall be in a format and substance acceptable to UNICEF.

Timeline and Deliverables

If not indicated otherwise in the contract documents the Consultancy Firm/NGO shall complete the assigned works as per the following schedule:

1. Desk study Report and Inception Report within 3 weeks starting from the date of signing of the   Contract;

2. Draft Report within one and half month of the Desk Study and Inception Report;

3. Final report within 2 weeks after receiving comments and suggestions on the Draft Report.

Expected background and Experience

The team of the Consultancy Firm/NGO that will be participating in the feasibility study must be professionals with Master degree in a related area of the work to be done, with at least 10 years of experience, doing similar works.

The person that will be leading the Consultancy Firm/NGO should be fluent in Arabic, and have a good knowledge of English.

The members of the team would need to have good analytical, communication and report writing skills.
