The contract with Tri-Tech Holding covers landfill site construction engineering and design, underground water monitoring, leachate drainage system, landfill gas pipe system and site closure cover system. The project will utilize an enhanced sanitary landfill process, combined with a composite impervious system, and a geosynthetic clay liner (GCL) with high-density polyethylene (HDPE) geomembrane to protect underground water resources and the environment.
The Xinle landfill will be 114,000 square meters, with a total disposal capacity of 1,197,000 cubic meters. It will have a daily disposal capacity of 220 tons, servicing the entire Xinle downtown and nearby suburbs with a population of 460,000. With a municipal solid waste decontamination rate of 100%, this landfill will ensure the harmless treatment of Xinle's municipal solid waste for the next 10 years.
Warren Zhao,Tri-Tech CEO said: “We are extremely pleased to be awarded this project after the Xinle City wastewater treatment plant upgrade work. This is the first residential solid waste landfill funded by Xinle government. With the rapid economic growth in Xinle, the amount of residential waste is increasing. The implementation of this project will reduce pollution from random-dumped urban refuse and will improve Xinle City's natural environment and preserve underground water quality.”
Tri-Tech expects to complete construction and transfer the landfill to Xinle City by November 2010.
