The Philippines is surrounded by the sea and has many nature-rich islands, attracting many tourists from overseas. Although the tourism industry was affected by the COVID-19 pandemic since 2020, it is now recovering. At the same time, with the increase in tourists from overseas, the amount of wastewater discharging from hotels, restaurants, sightseeing spots etc. is also increasing, and if not properly treated, the pollutant load on the water environment will increase. In addition, the number of fast-food restaurants is throughout increasing the Philippines due to the progress of urbanization, the increase in the young population, and the increase in national income. These changes in dietary habits and the expansion of the food and beverage industry are also contributing factors that increase the pollutant load on the water environment.
The Department of Environment and Natural Resources (DENR) Administrative Orders DAO 2016-08 and DAO 2021-19 stipulate Water Quality Guidelines and Effluent Standards. To preserve the country's rich water environment, it is important to properly treat wastewater discharged from the tourism and food and beverage industries and meet these standards.
A centralized sewerage system with collective treatment requires a long time to lay pipelines and construct treatment plants. In suburban areas with low population density, the advantages of scale are limited. Therefore, decentralized wastewater treatment facilities can treat domestic wastewater more efficiently and economically in rural and sub-urban areas. Also, in urban areas where new and old buildings coexist, traffic congestion is frequent, and in areas with rough terrain, decentralized wastewater treatment facilities may be more advantageous. This is because laying pipelines and securing land for sewage treatment plants are often difficult in such environments.
To comply with the Philippines' Water Quality Guidelines and General Effluent Standards, it is considered effective to promote wastewater management by proactively utilizing not only centralized wastewater treatment facilities but also decentralized wastewater treatment facilities that are guaranteed to have treatment capacity that can meet the standards.
In this seminar, we will focus on decentralized wastewater treatment facilities and discuss the policies and challenges for their dissemination in the Philippines. We will also introduce the characteristics of Johkasou, a Japanese decentralized wastewater treatment system that is widely used in Japan, and the related legal framework .We hope that this seminar will contribute to the conservation of a healthy water environment in the Philippines.
