Overview
- Sunass’s Cami Yaku analysis published Wednesday shows universal potable water and sanitation would lower national multidimensional poverty from 39.7% to about 34.0%, a drop of roughly 5.66 percentage points.
- The simulated impact is strongest in rural areas, where incidence would fall from about 78.9% to 69.9%, a reduction of roughly 9.02 percentage points.
- The study finds roughly 2.6 million people who are not poor by income still lack potable water, underlining that income measures miss many basic-service shortfalls.
- Sunass stresses the results are an accounting exercise that removes water and sanitation deprivations while holding other deficits constant and does not forecast how fast change would occur in practice.
- Practical barriers identified include per-connection costs that can reach S/90,000 in peri-urban or high-altitude sites, population shifts toward the coast, and disordered urban expansion, all of which raise the price and technical difficulty of universalization.
