One of the issues the Chinese government currently faces is how to protect the environment in vast, rural areas of the country. China’s rural areas currently produce over 9 billion tons of wastewater and 280 million tons of household trash every year.
According to recent statistics, agriculture accounts for over half of all the pollution in the country. Most of China’s 600,000 rural villages lack adequate water treatment facilities and untreated wastewater is released directly into rivers or the soil.
Water treatment under special circumstances
However, this task is not easy. The villages often lack proper, uniform sewage systems, are very small in size and great distances often separate them. Many times villagers lack the expertise needed to operate highly complicated systems and acquiring chemicals required for the purification process may prove to be extremely difficult.
Finding a way to solve these issues is crucial for the success of the Water Stewardship project. Water treatment systems and equipment have been selected so that they can work efficiently even on a small scale and are fairly simple to use.
Preparing for pilot projects in Guangxi
The pilot projects in Guanxi will utilize small-scale septic tanks and biological wetlands. The project starts with constructing sufficient piping to gather all sewage water in the village. The pilot projects will be introduced more in detail later.
Water is then channeled towards a common septic tank that will gather the biggest waste particles on the bottom of the tank. After this phase, the water is directed towards a constructed wetland that will naturally filter the water back into the soil and remove the remaining impurities.
The chemical and biological solutions used in the septic tank and the wetland are selected to be self-sustaining or so that villagers can easily refill the materials.
