Changes

Based on research from the [[#WASHCost|WASHCost]]project, the minimum operations and minor maintenance expenditure to provide a basic level of water service with a borehole and handpump (at 2011 prices) range from US$ 0.5 per person to just over US$ 1 per person (see table 1). For all piped schemes, including mechanised boreholes and piped supplies, the costs range from US$ 0.5 to just over US$ 5 per person.
