In 2018, Chaoyang District of Beijing plans to upgrade and transform 53 public toilets in urban-rural fringe zones with vacuum sewage discharge technology, which is now applied at toilet-flushing devices on planes and high-speed railway trains.
Niuwangmiao public toilet is the first public toilet in the city that was put into use after being upgraded and transformed with the vacuum sewage discharge technology.
“The biggest advantage of the vacuum sewage discharge technology is saving water,” an official introduced. The water consumption is about six liters for each flushing at a common public toilet while owing to this technology, the water consumption is greatly reduced to only 0.5 liter, with a water saving rate of over 90 percent. Besides, the technology has deodorant and antifreezing functions.
At present, two public toilets have completed the construction of introducing the technology and the rest of 53 public toilets are expected to complete the construction and be put into use by the end of August.
In addition, the district plans to complete the upgrade and transformation of 1,081 substandard public toilets by the end of November, aiming to achieve a goal of 100 percent of standard public toilets in the whole district.
