1、Utility Services - SewageSewageSIP has its own Sewage Treatment Works was developed by CSSD and has started operation since November 1998. The current treatment capacity of this plant is 100,000 m3/day and will be increased to 500,000 m3/day as the park develops.Fee and TariffsThe fee structure for
2、sewage is similar to that of water. There are one-off payments for connecting to the sewage network. These are the Increased Capacity Fee (增容费) and Engineering Fee (工程费). In addition, there are monthly consumption fees.Increased Capacity FeeThis will be computed based on 80% of the daily peaked capa
