Recently, the Office of the Joint Conference of Rural Toilet Renovation in Shandong Province issued the Pilot Work Plan for Creating and Improvement of Rural Harmless Sanitary Toilets in the Eastern, Central and Western Province (2018-2020). As a pilot area in the east China, Weihai is urgently needed to promote integrating both works of rural toilet reform and domestic sewage treatment, and explore an upgraded version of toilet revolution.
How to renovate and upgrade rural toilets? The Plan clarifies the ways to effectively carry out both the toilet reform and rural domestic sewage treatment. For the villages that have not reformed their toilets, they in principle may adopt the modes the modes of single family, multi families or whole village to include their sewage into a pipe network, so to collectively treat the toilet sewage and kitchen sewage and all other domestic sewage such as bathing and soaking waste water, and thus realizing the treatment and control at the pollution source end and in just one step. For the single-family treatment mode, it takes a household as a unit, to install a small single-family processing facility that is used to collect all the domestic sewages such as toilet sewage, kitchen sewage, bath water, and laundry waste water. For the relatively centralized processing mode, it takes multi-family or whole village as a unit, to construct domestic sewage treatment facilities that are used for centralized collection and treatment of domestic sewages. For the tube management mode, it is deployed for households that are in a village close to a town. Each household will set up a sedimentation tank, and each village will lay down a pipe network through which the domestic sewage will be sent and included in the town sewage treatment plant for centralized treatment. It also encouraged qualified villages to use the ways of artificial wetland or oxidation ponds for ecological treatment.
According to the Plan, in principle the pilot city will select 1-2 counties (cities, districts) to carry out pilot projects. Other cities and counties should also carry out the pilot project at different levels such as counties, towns, and villages, based on local actual conditions. The pilot will be fully launched by the end of the year. In 2020, the successful experience of the pilot will be gradually promoted throughout the province.
