While public sewage systems are widely used to treat domestic sewage, many places where public sewage systems do not reach rely on on-site sewage treatment facilities. Therefore, it is important to manage the on-site sewage treatment facilities. This project evaluated the strategies of managing on-site sewage treatment facilities by literature review, investigating the treatment efficiency and the carbon emission of sewage treatment facilities, onsite inspection, convening expert consultation meeting, and holding training courses of operation and management of community sewage treatment facilities, to oversee the management of domestic sewage discharge, emphasize the importance of profession, and improve the management system. This project also drafted "Mandatory and Prohibitory Provisions of Standard Contracts for Commissioned Operations of Community Sewage Treatment Facilities", reviewed registration cases for eligible prefabricated building sewage treatment facilities, summarize the outcomes of local governments’ domestic sewage pollutant reduction projects, and assisted local governments to accelerate the enacting of regulations for domestic water pollution control fee.
