AbstractIdeally, wastewater management (WWM) accompanies water supply system. In developing countries for financial and technological constrains, WWM did not receive sufficient policy attention until wastewater (WW) started to seriously pollute surface water and ground water – the two major sources of water supply. Because of these negative externalities associated with water pollution and high capital costs of wastewater treatment system (WWTS), use of economic instruments (EIs) – subsidy for construction of treatment facility and charges WW customers – is a highly desirable environmental policy direction to take. Unfortunately developing countries have not yet been able to make use of EIs, particularly in WWM. Thailand took a bold initiative as early as 1992 to change this situation, since water pollution has been rising alarmingly. Its reinvigorated environmental act, established an Environmental Fund (EF) to provide subsidy for the construction of WWTS, along with setting the requirement to levy charges to promote the polluters-pay principle (PPP). Since then sixteen years have passed, and the utilization of EF as well as the levying of charges is still limited. With this background, this research investigated three selected cities – Bangkok, Saensuk and Patong – regarding the reasons for the prevailing situation. The methodology of the study involved a two-level investigation: at the municipal level, the focus was on constraints encountered by local government in implementing the charges to the wastewater generators; and at the household level, the focus was on determining residents’ attitudes and perceptions to WWM in general and charges in particular. Analysis of the compiled information and survey data suggest (a) the elected leaders in the local governments – who have been given responsibility to implement charges – are concerned that levying charges may lead to loss of support for them in an election; (b) residents are not so willing to pay because they expect such services are to be paid from tax revenues. Thus, the willingness to charge (WTC) and willingness to pay (WTP) have become intertwined. The other set of findings include the complexity in obtaining the required fund from EF. The findings’ policy implications include actions by: (a) local leaders for keeping the residents informed of municipal service management & showing the residents the tangible gains associated with good WWM and (b) central government for easing the complexity in approval of fund applications and its disbursement from the EF & creating the necessary legal basis for implementation of the charges by the local governments.
