In a context of greater pressure on water resources, ensuring continued and adequate access to safe water supplies will require the investment of significant funds and expertise in public sewerage and water and wastewater treatment infrastructure. After a short introduction, this paper examines the recent trends in the development of wastewater infrastructure. It then discusses the investment needs and reviews the potential sources of funding, before turning to recent trends in private-sector participation in water and wastewater treatment infrastructure and the framework conditions to make this participation work in the public interest.
