Research on the Pricing of Reclaimed Water: A Case Study of a Wastewater Reclamation and Reuse Project

Abstract

The reclaimed water produced by sewage treatment plants can be reused for many purposes, which has gradually been paid great attention. However, its pricing mechanism has not been well established especially in China, which has brought certain restrictions on the wide application of reclaimed water. Therefore, this paper attempts to analyze the current situation of domestic reclaimed water pricing, combined with the research and analysis of reclaimed water production costs and related industry profits, and gives the recommended reclaimed water pricing. Taking the reclaimed water reuse project in Ningbo, China as an example, the cost and profit are analyzed by season. The recommended price in non-winter is 0.3833 yuan/ton, and the recommended price in winter is 0.4283 yuan/ton. This study may provide some reference for the improvement of the pricing mechanism of reclaimed water, thus contributing to the wide application of reclaimed water.
