In 2015, the Millennium Challenge Corporation (MCC) partnered with the Government of Liberia (GoL) to help address the country's insufficient access to reliable and affordable electricity. Under MCC's compact with the GoL, the $202 million Energy Project aims to modernize Liberia's energy network, extend access to electricity, and improve the quality and reliability of the country's power system. MCC has contracted with MPR to to conduct impact and performance evaluations of four separate activities and investments. This report outlines the proposed evaluation design of the Mt. Coffee Support Activity, which includes a sub-activity to restore and upgrade the raw water pipeline to the White Plains water treatment plant. The $18 million water pipeline sub-activity is expected to improve LWSC's capacity to serve more than one million customers in and around Monrovia who currently lack an adequate supply of clean water. The gravity-fed pipeline system is expected to reduce the cost of pumping water to the treatment plant, improve raw water quality by substituting a less saline source than the previous location along the St. Paul River, and provide a more consistent supply of potable water.
Mathematica has proposed a performance evaluation to assess the pipeline implementation and whether the water pipeline sub-activity was able to meet the outcomes as set out in the theory of change, as well as a recalculation of the economic rate of return (ERR) and update of the cost-benefit analysis. Mathematica will draw on documentation, administrative data, site visits and key informant interviews (KIIs) to answer the evaluation questions.
