T3 – Stormwater Management

In recent years, particular efforts have been made to reduce the waste water discharge into Dianchi. As detailed in sub-project T1, this included upgrading Kunming’s WWTPs.  With a total sewer length of 2,670 km, the city operates 1,100 km of stormwater sewers and 385 km of combined sewers. Exemplary efforts have been undertaken in recent years and measures have been put into place to minimize the substance loads into Dianchi, i.e. mainly the construction of retention basins and facilities for the treatment of combined discharges. Picture 4-8 shows the city’s sewer network, with the red areas within the second ring having combined drainage systems.

The project’s objectives include …

Demonstration of optimization possibilities for an existing part of Kunming’s sewer network
