Reservoir Regional Water Treatment In China

In 2017, GEO designed a state of the art regional treatment system to treat runoff from 128 hectares (316 acres, or 1/2 sq. mile) of intensely developed urban sources contaminated with stormwater illicit connections.  This system owned by the local water utility, will treat runoff prior to it entering the
Mengjiawan Reservoir, ZhenJiang, China. The system comprised of two Advanced Bioretention Systems (ABSs) with a combined treatment area of 3,600 sq. meters (0.9 acres). A high rate engineered media allowed for a compressed treatment footprint resulting in 0.3% of the source area. 

Integrated into the reservoir’s landscape plan, this complex treatment facility now treats this entire area prior to discharge into the Mengjiawan Reservoir, the headwaters of the Yudai River.  Completed in mid-2018, the system has now been operating for half a year with excellent results.
