Stormwater drainage• “In the slums and shanty towns of the Third World, many residents feel that they need drainage more urgently than water supply or latrines . . . Many neighborhoods are flooded several times a year, and people have to cope with water or other people’s sewage inside their dwellings.”
– Cairncross and Feachem
