Rural domestic sewage has become the focus of rural environmental remediation nationwide.  With the improvement of rural living standards, the improvement of tap water supply, and the soundness of sanitary facilities, the traditional sanitation model has been disrupted, leading to a significant increase in domestic sewage, reaching a point where it must be treated.  Since the start of rural domestic sewage treatment nationwide, which has been nearly 20 years now, substantial investment has been accumulated, and lessons learned have been plentiful.  However, there has yet to be a very successful demonstration that can be widely promoted.  In response to this issue, DWI in collaboration with local housing, environmental protection, and agricultural departments, has embarked on a series of studies.  Through research, sampling, and experimentation, the aim is to conduct a fair assessment of the current status of rural domestic sewage issues and diagnose the problems currently faced.

• Study on sewage pipeline design in rural sewage treatment

• Research on single-household sewage treatment processes and equipment

• Study on problems and countermeasures in rural domestic sewage treatment

• Development of centralized management platform for distributed sewage treatment facilities
