| Summary: | The Philippines is well on its way to
achieving the sanitation target, which is part of a combined
drinking water and sanitation target within the Millennium
Development Goal (MDG). As of 2008, about 76 percent of its
population had access to improved sanitation facilities (JMP
2010). This is nearly 18 percentage points higher than the
estimates for 1990 and 3 percentage points short of the MDG
target for sanitation. This study aims to generate evidence
on the costs and benefits of sanitation improvements in
different contexts in the Philippines. Conducted with a view
towards identifying the most economically efficient options
under different conditions, it aims to contribute to the
decision making processes of government, donor agencies, and
non-governmental organizations (NGOs) and other
institutions. The study quantified the costs and benefits
associated with various sanitation options in different
study sites. The benefits included the impacts on health,
water sources and treatment, access time, and the reuse of
human excreta. The costs included capital or investment
costs and the recurrent costs associated with various
sanitation options. The costs and benefits of the sanitation
options were synthesized using standard indicators of
economic efficiency. These indicators included the
benefit-cost ratio, cost-effectiveness ratio, net present
value, internal rate of the return, and payback period of
sanitation options. Cost-effectiveness ratios cost per
disability life year averted, cost per disease case averted,
cost per death averted were also calculated. |
