September 25- 29, 2017, Tokyo, Yokohama - World Bank’s Tokyo Development Learning Center (TDLC) organized Technical Deep Dive (TDD) on Integrated Urban Water Management from September 25 to 29, 2017, jointly with the World Bank Social, Urban, Rural and Resilience Global Practice (GPSURR), Water Global Practice (GP), CPP partner city of Yokohama and the Government of Japan. The TDD consisted of active learning sessions and site visits to Tsurumi River Multipurpose Retarding Basin and Hokubu II Sludge Treatment Center in Yokohama. Practitioners and experts from 14 countries (Argentina, Bangladesh, Brazil, China, Ghana, Honduras, Indonesia, Kenya, Nicaragua, Philippines, Senegal, Sierra Leone, Tanzania, Turkey, Vietnam) attended this TDD and discussed challenges that each country is facing and learned practical solutions from Japan.


The sessions started with framing Integrated Urban Water Management (IUWM). Catalina Marulanda, Practice Manager of World Bank’s GPSURR said, “IUWM is not new science or new technology. It is a new way to look at water issues and to look for the best approach for a specific site.”


Japan has a rich history of managing water including reusing and recycling. The key to successful water treatment in Japan involves stakeholder coordination and citizen involvement. Yoshihisa Iwasaki, Director of Water Resources Department of Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and Counselor for Policy Planning Coordination, Cabinet Secretariat addressed IUWM challenges at national, state and local level in Japan.


Solid waste management is one of the critical issues to be considered in IUWM. If not managed properly, it can affect on water quality and ecosystem, cause flooding due to interference with workings of drainage system, and eventually cause health hazards to the citizens. John Morton, Senior Urban Environment Specialist of WBG claimed that integrated planning of urban development and water services, source controls such as waste reduction and educational campaigns are essential.


The economic and financial aspects of IUWM was also discussed during this TDD. Diego Rodriguez, Senior WRM Specialist of WBG presented on the economic and financial aspects of IUWM and its financing options. Participants were lead to play financial and economic simulation game in a fictional bayside city where the participants create their own water management investment program under given conditions.


Sanitation aspect is another important issue raised during the sessions. By pointing out that everything is interconnected in a city, Martin Gambrill, Lead Water and Sanitation Specialist of the WBG, claimed the importance of citywide inclusive sanitation which is a comprehensive approach to sanitation improvements, encompassing long-term planning, technical innovation, institutional reforms and financial mobilization. Site visit to Yokohama to learn about Japanese experience on maintenance of Tsurumi River and watershed, recycling water including sludge treatment.


Sites visits to Tsurumi River Multipurpose River Basin and Hokubu II Sludge Treatment Center in Yokohama were planned to learn the city’s efforts in its maintenance of the river and watershed and water recycling including sludge treatment. Participants consolidated their action plans and presented them at the end of this intense 5-day event. The key takeaways raised during the presentation were land use planning and integrated approach for urban water, institutional collaboration and coordination, participatory planning in advance and community involvement in each stage are essential for Urban planning.  Assistance of experts on the integration of DRM into conservation plans and urban heritage was also mentioned by some clients.
