The aim of this study is to measuring the efficiency of Water and Wastewater Company (WWC).
Data Envelopment Analysis (DEA) is a body of research methodologies to evaluate overall efficiencies and
identify the sources and estimate the amounts of inefficiencies in inputs and outputs. In DEA, the best
performers are called DEA efficient and the efficiency score of a DEA efficient unit is denoted by a unity. It
is possible to prevent wasting resources and unreasonable increase of costs by measuring efficiency of various
sections of the economy, especially servicing and nonprofit units. This research attempts to measure and
compare technical efficiency value of 17 municipalities of Markazi province (Iran) in urban Water and
Wastewater Company (WWC) by using DEA. Data for 2006 were used to estimate efficiency scores. The
results indicated less than 30% of municipalities were fully technically efficient that could be referred as
inefficient units. Capital input and water losses were the major source of the inefficiency. Thus, the policy
makers should focus on rebuilding the infrastructure of the water networks, beginning with the most DEA
inefficient municipalities in order to minimize water losses and maximize efficiency of capital input.
