Since the early 1990s, DW has implemented a series of successful programmes in the shanty towns to improve access to basic services. To date, DW has built 220 water standpipes, which bring clean and affordable water to around 120,000 people. To address the sanitation problem, DW has helped build close to 10,000 latrines, and pioneered solutions for solid waste removal. The central strategy is to build partnerships of the stakeholders in a programme and encourage collaboration and trust between them.
