This report is part of a larger World Bank effort that seeks to provide analytical and strategic assistance to Bank staff and utilities in client countries as they begin to consider the implications of climate change on water resources. The key objectives of this document are to: improve understanding and awareness of the operational implications of climate change on the provision of water and wastewater services by urban utilities; present adaptation actions conducted at the utility level for inspiration; establish an analytical framework to assist Bank staff and client countries' utility managers to identify and prioritize potential climate change adaptation measures; and assess the feasibility of implementing adaptation measures based on a set of criteria.
