1 TERMS OF REFERENCE FOR SERVICE CONTRACTING Assignment Location Equip Rukban borehole with a containerized Reverse Osmosis desalination Plant and operate/maintain for six months after commissioning Rukban, Ruwayshed, Mafraq Governorate, Jordan. Total contract duration Reporting to Nine months comprising three months for the design, installation, testing and commissioning, and an additional six months of operation WASH Section - UNICEF Jordan 1. JUSTIFICATION/BACKGROUND Rukban is located in the extreme north-eastern corner of Jordan (at the Jordan-Syria-Iraq border), approximately 7km west of the Iraqi border and 1km south of the Syrian border (see map). Currently, there are approximately 50,000 Syrian asylum seekers living in an area in between the Syrian and Jordanian border, in No Man s Land. The population in Rukban is currently approximately 50,000 people and it may expand rapidly due to the changeable situation in Syria. As Lead Agency in the WASH sector in Jordan, UNICEF is providing water to Rukban, currently estimated at about 650 m 3 /day however, this should be increased, due to the increasing seasonal needs, and potential population increase. Currently, the water is trucked over 140km from Ruwayshed Water Treatment Plant to Rukban with many concerns related to the water quality as well as many interruptions to services due to inaccessibility after storms as well as truck breakdowns. In agreement with the Ministry of Water and Irrigation, UNICEF drilled a borehole in Rukban in December The borehole was drilled to a depth of 572m and has an estimated yield of 70m 3 /hr. The borehole was drilled to increase the volume of water supplied to those living in No Man s Land in Rukban, and to ensure a continuous supply of water. The borehole was pump tested twice, and the latest set of water quality results are given below. The aim of this project is to install a treatment system to treat the water from the borehole in Rukban and to ensure it meets the Jordanian drinking water standards. On the basis of the water quality results, UNICEF Jordan is seeking a qualified company to design, assemble, install and operate (for six months) a containerised reverse osmosis unit, and to operate it for six months. The proposed system should address the raw water quality characteristics of the water. The key parameters from the WAJ laboratory test results are given as: Raw water quality parameters, as per WAJ laboratory test PLEASE CHECK ANNEX D Effluent Quality Page 1 of 7

2 The final produced water (including approx. 9% blended water) from the RO unit must meet the national drinking water requirements of JS 286/2008 (and electrical conductivity should not exceed 600 µs/cm). Access The borehole is located in a military closed area (administered by the Jordanian Armed Forces JAF). Access to the site for personnel and equipment will require security permits issued by JAF and these will be processed by UNICEF for the first time. Renewal of the permits is the contractor s sole responsibility. 2. OBJECTIVE AND TARGETS A. Project Objective The aim of this project is to design, assemble, install, test, operate and maintain a water treatment plant to treat the water from Rukban borehole and provide safe drinking water to the asylum seekers in Rukban, which meets the national drinking water standards (JS 286/2008). B. Site location The Rukban borehole is located at the north-eastern border and is in the vicinity the JAF military camp. The Treatment plant will be installed at the borehole. The exact coordinates of Rukban borehole location are; X: Y: UTM, Zone 37, as per the attached map. The current site is being installed, and the planned layout is given as in the attached drawing. The borehole will be fitted with submersible pump and is installed at mbgl and is planned to abstract at a rate of 70m 3 /hr. A data logger (to record the water levels, ph and conductivity) will be installed in the borehole and a panel provided for the readings. UNICEF will provide and install a furnished office and living accommodation at the Rukban borehole. C. Key Requirement parameters: - The plant MUST be a Containerized Reverse Osmosis desalination plant and shall be designed, constructed, installed, tested, commissioned and operated to treat m 3 /hr - The plant shall consist of the following items (raw water tank, aeration tower and RO unit) and the contractor is responsible of all pipe connections from the wellhead to the raw water tank to the RO unit.
