The Project Appraisal Document (PAD) is essentially the same, but with slightly different wording: "Sustainable improvements to the public health and well-being of around 1.2 million residents of HCMC [Ho Chi Minh City], particularly the poor, and promotion of increased economic development in the commercial center of the city. This will be achieved by reducing wastewater pollution and the occurrence of flooding and by developing a more efficient institution to manage drainage and wastewater services" (PAD, p. 2).
