In developing countries, the construction of sewerage systems with pipe networks has been delayed due to various obstacle factors such as the shortage of finance and rapid expansion of cities, and, therefore, the appropriate wastewater treatment services are often not available even in the urban areas. The decentralized domestic wastewater treatment facilities with the high treatment performance, such as Johkasou, are expected to play a valuable role in compensating for the delays in sewerage system development. In Japan, in some cases, the Johkasou system is applied for public works projects according to the Johkasou Act instead of the centralized wastewater treatment systems (sewerage system) to improve the water quality of public water bodies in sub-urban and rural areas.
In any decentralized wastewater treatment system such as septic tanks or Johkasou, fecal sludge is also always generated through the process of treating wastewater. This means wastewater management requires fecal sludge management (which includes the collection, treatment, disposal, reuse, etc. associated with wastewater management), as two sides of the same coin. In addition, wastewater management and fecal sludge management (FSM) cannot be implemented without an appropriate legal framework which can set up a fee collection system, incentives for private companies, a monitoring system, operation and maintenance system, or other measures. However, it is particularly difficult to install a reasonable tariff mechanism in some countries because of economical reason (for household accounting), or existing habits (in addition to the low willingness to pay for wastewater or FSM). Therefore, is it not one of the most appropriate options to consider wastewater management and FSM as public works projects to be implemented under the responsibility of the central / local governments (administrators), to achieve sustainability?
In this workshop, the main issues related to FSM will be sorted out and raised through the review of case studies from several countries. Several administrative responses that can be taken to achieve appropriate FSM for sustainable decentralized wastewater management will be presented and discussed. Governmental officials, administrative officials, related organizations' officials, and researchers of Asian countries are expected to participate in this workshop.

Session A
Sustainable Decentralized Wastewater Management
In this session, MOEJ will introduce a case study from Japan in which decentralized domestic wastewater treatment systems are sometimes installed as public works projects similarly to sewerage system (A-1), and Prof. Fan Bin from Chinese Academy of Science, will share information on Johkasou projects adopting a PPP (Public Private Partnership) scheme in China (A-2).
