Economic Efficiency
Economic efficiency of water supply can be measured through several indicators. In Benin however, access to the respective data, in the case that they exist, is difficult. However, a frame contract (contrat plan) for the period 2008–2010 between SONEB and the Ministry in charge of water has been signed January 2008. It contains an indicator set allowing to measure achievements of objectives of the urban water strategy adopted in 2007. SONEB documents these achievements in the yearly sector review.
One established indicator is the share of non-revenue water (NRW), water which is produced but not billed due to several reasons like leakage and illegal connections. According to the Beninese Ministry of Economic and Financial Development, NRW of SONEB was 21% in 2004. Although there is no agreement on appropriate levels of NRW among professionals, Tynan and Kingdom propose a best practice target of 23% in developing countries. According to the figures of the ministry, SONEB complies with that target.

Famous quotes containing the words economic and/or efficiency:
“... feminism is a political term and it must be recognized as such: it is political in women’s terms. What are these terms? Essentially it means making connections: between personal power and economic power, between domestic oppression and labor exploitation, between plants and chemicals, feelings and theories; it means making connections between our inside worlds and the outside world.”
—Anica Vesel Mander, U.S. author and feminist, and Anne Kent Rush (b. 1945)
““Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
