The investments needed to deliver sustainable water and sanitation services, including the funds that are needed to operate and maintain the infrastructure, expand their coverage and upgrade service delivery to meet current social and environmental expectations, are huge. Yet, most systems are underfunded with dire consequences for water and sanitation users, especially the poorest. Providing sustainable drinking water supply and sanitation services requires sound financial basis and strategic financial planning to ensure that existing and future financial resources are commensurate with investment needs as well as the costs of operating and maintaining services. Some of the key messages of this report are: WSS generate substantial benefits for the economy Investment needs to generate these benefits are large in both OECD and developing countries Tariffs are a preferred funding source, but public budgets and ODA will have a role to play, too Markets-based repayable finance is needed to cover high up-front capital investment costs Strategic financial planning and other OECD tools can help Governments move forward

The investments needed to deliver sustainable water and sanitation services are huge, yet most systems are underfunded. This book provides practical tools for investment and financial planning related to water.

Investments in water and sanitation are a prerequisite to deliver on the Sustainable Development Goals (SDGs), in particular on SDG 6 ensuring availability and sustainable management of water and sanitation for all. Blended finance can play an important role in strategically investing development finance to mobilise additional commercial finance needed to fill the current investment gaps. Thus far, however, blended finance has not reached scale in the water and sanitation sector. A greater evidence base is needed to better understand the current applications as well as the potential of blended models in the water and sanitation sector. This publication takes a commercial investment perspective and provides insights into three subsectors: (1) water and sanitation utilities, (2) small-scale off-grid sanitation and (3) multi-purpose water infrastructure and landscape-based approaches. The publication draws out recommendations for policy makers and practitioners to apply and scale innovative blended finance approaches where most appropriate.

Water policies around the world are in urgent need of reform. Despite improvements in some sectors and countries, progress on meeting national, regional and international goals for managing and securing access to water for all has been uneven. Rallying policymakers around a positive water reform agenda needs to be a high priority and calls for strong political commitment and leadership. This report on Meeting the Water Reform Challenge brings together key insights from recent OECD work and identifies the priority areas where governments need to focus their reform efforts. It calls for governments to focus on getting the basics of water policy right. Sustainable financing, effective governance, and coherence between water and sectoral policies are the building blocks of successful reform.

This paper focuses on how to improve the development and management of water resources while providing the principles that link resource management to the specific water-using sectors. In 1993 the Board of the World Bank endorsed a Water Resources Management Policy Paper. In that paper, and this Strategy, water resources management is seen to comprise the institutional framework; management instruments; and the development, maintenance and operation of infrastructure. The paper looks at the dynamics of water and development. It builds on the 1993 policy paper, evaluating current scenarios and looking at future options and their implications both for government policy and the World Bank.

Building on the main water challenges identified by the OECD Environment Outlook to 2050, this report examines financing of the water sector; the governance and institutional arrangements that are in place; and coherence between water policies and policies in place in other sectors of the economy.

This Book includes selected papers that has been published in the Water journal Special Issue (SI) on Water Supply and Water Scarcity. Moreover, an overview of the SI is included. The papers selected for publication in the SI include review and research papers on water history, on water management issues under water scarcity regimes, on rainwater harvesting, on water quality and degradation, and on climatic variability impacts on water resources. Overall, the issue identify and highlight the main challenges in water sector, and particularly in management and protection of water resources and in use of alternative (non-conventional) water resources, especially in areas with demographic change and climate vulnerability in order to achieve sustainable and secure water supply. Furthermore, general guidelines and possible solutions for an improved and sophisticated water management system are proposed and discussed, such as the adoption of advanced technological solutions and practices that improve water-use efficiency and the use of alternative water resources, to address the growing environmental and health issues and to reduce the emerging conflicts among water users.
