Abstract A treatment charge based on the pollution level of wastewater flowing into the municipal wastewater plants has been the mainstream of the present pricing policy reform for municipal wastewater treatment. However, insufficient data on pollution level in wastewater led to difficulties in establishing proper treatment charges. An investment and operation cost function model was developed for municipal wastewater treatment using the national pollution census data. It calculated the average unit cost for wastewater treatment of different pollution loads and different discharge standards in eastern, central and western regions given the current municipal wastewater treatment cost accounting system. Taking into account the cost for pipe work depreciation, testing and monitoring, and sludge treatment, a wastewater treatment charge standard system was developed for the three regions. The results may lay the basis for reforming the wastewater treatment charge standard system.
