TEDA discharge basin remediation project

The TEDA discharge basin is located in the east area of the Tianjin Economic and Technological Development Zone. The length of the treatment section is 2.3 km and has a width of 25m to 40m. The flow rate of the rainwater runoffs to the discharge basin can reach up to 80m³/s. Aside from pollution, the discharge basin contains a high salinity due to seawater intrusion making biological treatment extremely difficult. The channel’s cross-section adopts a trapezoidal cross-section. 4 pumping stations directly discharge collected stormwater from throughout the city and wastewater treatment plant tailwater into the basin.
