The top priorities for urban water sustainability include the provision of safe drinking water, wastewater handling for public health, and protection against flooding. However, rapidly aging infrastructure, population growth, and increasing urbanization call into question current urban water management strategies, especially in the fast-growing urban areas in Asia and Africa. We review innovative approaches in urban water management with the potential to provide locally adapted, resource-efficient alternative solutions. Promising examples include new concepts for stormwater drainage, increased water productivity, distributed or on-site treatment of wastewater, source separation of human waste, and institutional and organizational reforms. We conclude that there is an urgent need for major transdisciplinary efforts in research, policy, and practice to develop alternatives with implications for cities and aquatic ecosystems alike.

The need for taking a comprehensive perspective when selecting sanitation technologies in developing contexts has been increasingly discussed. Process guides, which are planning documents describing steps decision-makers need to take, represent one possible contribution to attain comprehensive decisions. An interview study with sanitation experts was carried out to understand the importance and real use of such planning documents for the selection of urban sanitation technologies in developing countries, as well as to understand the relevance and actual consideration of decision elements and to identify recommendations for taking them into account. Although process guides appear to be helpful to guide planning processes, their use does not seem to be common practice. It is actually doubtful that the sector is currently able to make better use of those documents in the form that they exist today. Furthermore, the importance of a comprehensive approach is generally recognised, but relevant decision elements were said to be often neglected. Finally, results from the interview analysis also emphasised the need for a conducive policy environment, namely by developing appropriate institutional and legal frameworks, and by incentivising planners and decision-makers to further adapt to comprehensive decision-making practices that effectively improve the sanitation situation in developing countries.

Multilateral development banks (MDBs) play a pivotal role in financing water and sanitation infrastructure projects and thus have a major impact on the development of basic services. Although information about the MDBs’ investments is publicly available, it is dispersed and not easily comparable. A comprehensive compilation of MDBs’ water and sanitation investments has long been lacking. To address this gap, we assess water and sanitation financing by the three MDBs most relevant to Africa and Asia between 1960 and 2020: the World Bank, the African Development Bank, and the Asian Development Bank. We compile a new dataset by drawing on 3,639 water and sanitation projects and assess territorial trends, technology choices, distribution of financial burdens, and reforms to institutional arrangements. We find that MDBs’ investments align with changing patterns of urbanization and increasingly finance sanitation infrastructures including non-sewered technologies. However, our results also suggest that institutional reforms have addressed utility efficiency through investment in equipment and skills rather than through increased commercialization and private sector participation. The leverage effect of MDB investment on private financing is negligible, whereas co-financing from local governments dominates.
