LESSONS LEARNED IN THE DESIGN-BUILD APPROACH OF TANNING WASTEWATER TREATMENT SYSTEMS IN CHINA

The preliminary design package and Design-Build documents were prepared by a United States (US) engineering firm for the Owner to bid for the Design-Build of a Wastewater Treatment (WWT) system for its leather tanning facility in Guan Dong Province, People's Republic of China. The US engineering firm provided its expertise to determine the treatment process units and a local Contractor furnished the detailed engineering design, equipment procurement, construction and start-up services. A 1,440 cubic meters/day (CMD) secondary WWT system, with carbon adsorption, was in operation approximately one year after the Request for Proposals (RFP) was issued and at a total cost of two million US dollars (US 2 million). The same parties participated in the expansion of the WWT system and lessons learned during the first phase were implemented to improve the results of an already successful partnership.
