Universal Intervention and Development Organization is a South Sudanese National and Christian organization found in 2004, the organization is legally registered by the Relief and Rehabilitation Commission (RRC). UNIDOR has a strong presence in the country and implementing multi-sectorial projects which are designed to alleviate severe suffering of the communities who are affected by the conflict and natural disaster. UNIDOR is also a member of different clusters in the country as well with NGOs forum the country’s humanitarian network body. UNIDOR's main thematic focus includes Health, Nutrition, WASH, Protection, Food Security and livelihood (FSL), Education and Peacebuilding and conflict mitigation.
As a consequence of continued civil war and repeated droughts, 7.2 million people in South Sudan are currently displaced. In the severely affected counties of Northern and Southern Liech, people have no access to clean water. Deep boreholes reaching the second aquifer have been deliberately destroyed.
In view of the precarious situation, returnees and IDPs can only return home once access to safe drinking water is secured. The project seeks to provide 25,000 people with access to safe drinking water by rehabilitating at least four to five deep boreholes (pumping capacity: 10,000 litres/day each) in Northern and Southern Liech.

General Terms & Conditions
BID TERMS AND CONDITIONS
SUPPLY AND INSTALLATION OF A SOLAR POWERED PUMPING SYSTEM
It is envisaged that the system is made up of the following components.
The locations are in Northern and Southern Liech State:
The exact location of the sites shall be shown to the bidder by UNIDOR staff on site or by providing an overview containing the exact GPS coordinates. The bidder is free to seek any clarification on the site characteristics from UNIDOR prior to commencement of the works. Bidders are encouraged to visit the site before bidding at their own expense.
When considering the design of the systems the following planning assumptions should be made for each of the respective sites.
|Location (Lat., Long.)|
|Daily Water Demand (m3)||From the pumping test report|
|Ground water temperature (°C)||30|
|Cable Length (m)||As per the bidder installation plan|
|Borehole Yield (m3/hr)||From the pumping test report|
|Depth of Borehole (m)||same as above|
|Size of Casing (inches)||4”|
|Static Water Level (m)||From the pumping test report|
|Dynamic Water Level (m)||Same as above|
|Tank Height (m)||6.5|
|Ground Elevation (m)||2|
|Delivery pipeline length to tank (m)||As per the bidder installation plan|
|Total Dynamic Head (m)||From the pumping test report|
|Max allowable cable losses||3%|
|Ambient Temps||Max. 45oC|
|Existing Tank Capacity (m3)||50|
Carefully disassemble and remove the existing items stated in the BoQ (will be made available upon request) such as wellhead, pumps, discharge hose, pipes, fittings, cables, steel structures, corrugated sheets and any other materials or equipment and hand them over officially to the representative of the respective community in the presence of UNIDOR staff. The hand over minute should include a detailed inventory of removed items.
The solar generator must be designed to provide adequate power to the system in real world conditions. Pure theoretical models must be avoided and bidders should show what assumptions have been made in calculating the solar generator size and include it in the design
The PV Modules shall be clearly labelled and permanently marked with a data plate containing the following information: manufacturer’s name and physical address, type/model number, the watt-peak power rating at STC, open circuit voltage and short circuit current, voltage and current at maximum power point, tolerance and temperature coefficient, country of manufacture, certification, e.g: UL listing, IEC 61215,ISO certification, with fool-proof +ve/-ve connectors
A power inverter shall be used to convert DC power from solar PV modules to AC power that can be used to power an AC motor-based water pump. The inverter shall act as a pump drive or controller manufactured and supplied to work with the specified pump type, and universally works well with induction motors; suitable for solar water pumping applications. The inverter shall be designed to provide useful information about voltages, switch and sensor status, and overload conditions; and deliver maximum power [maximum power point tracking (MPPT) and current boosting] under varying conditions. It should offer direct solar connection as standard and have the ability to add on an optional power back up if required in the future. The control equipment must meet EN 61800-1, EN 61800-3, EN 60204-1 or internationally recognized equivalent standards
Other desired features include:
Parts should be replaceable at a low level of modularity to reduce replacement costs. The bidder must recommend the items that would be supplied in line with manufacturer’s recommendation. Recommended service intervals for each component should be stated along with parts costs, time and skill level required to service. Spare parts must be readily available on site within 5 days.
|Component||Service task and spare Part||Frequency of task/ replacement||Time of activity||Skill level of technician||Consumables items and cost|
|Pump and motor
The scope will include but not limited to the following:
The defects liability period (DLP) is an integral part of this contract. The DLP is one year starts from the date of the official project handover to UNIDOR. During this period the contractor shall be responsible for repair or replacement at their cost any inferior material, poor workmanship defects or broken parts within 30 days from the UNIDOR official notice. Otherwise, UNIDOR can arrange to repair the defects at the contractor cost. Additionally, bidders shall submit with their bid, a priced proposal for a 2-year service agreement after the expiry of the warranty and DLP.
