“…Overall, private participation in water services, based on case studies and statistical or econometrical analysis, have produced mixed outcomes (Marin, 2009a; Kirkpatrick et al , 2004): some improvements in quality and reliability of water services and improved coverage are reported, but cases of high unaccounted‐for‐water, high water tariffs, low water quality and lower‐than‐expected private sector performance attracting public opposition and subsequent contracts cancellation are commonplace. Moreover, despite their instrumental role in some countries, PPPs in urban water supply present a new set of challenges (collectively “risks”) for the parties involved, such as the implementation of effective regulatory frameworks by the public sector (Shendy et al , 2011). PPPs in water supply have been very controversial (Prasad, 2006; Marin, 2009a), with a large number falling short of original targets, for example the anticipated surge in private investment flows only partially materialised (Hall and Lobina, 2006).…”
