1    Objectives and Scope

The electricity supply chain was the main energy source for water pumping stations. Due to the lack of financial resources to secure the fuel as well as the operational and maintenance cost, the electricity supply chain stopped functioning. The lack of electricity caused the discontinuation of the water pumping stations and water wells which resulted in the lack of access to clean drinking water. In response to this emergency, UNOPS Yemen in consultation with the respected local authorities are working on the selection of water wells based on specific technical criteria to be energized with solar pumping water systems under the Yemen Emergency Electricity Access Project phase II (YEEAP II) funded by the World Bank.

The purpose of carrying out the pumping and recovery tests for water wells is to evaluate the productive capacity of the selected / targeted wells to be rehabilitated and/ or provided by solar pumping systems.  This test will also measure the sustainability of the water well to provide drinking water in economically viable quantities and verify the hydraulic and water production performance. 

UNOPS will provide the basic data such as social, geographical and hydrological of the water wells that will give an indication of the status and physical parameters of the wells in advance of any call-off for the service. such data are indicative and to be verified by the contractor during the site assessment and data collection from the authorities and local communities.
