Fifteen individuals posing as sewer construction project workers are facing charges after allegedly dumping over 1,000 tonnes of sewage and waste oil through the manholes of an industrial city’s sewer network, Taiwanese prosecutors announced.
As reported in the Tapei Times, the alleged dumping ring used two compact excavators and nine sewage trucks to operate in the city of Taichung, where the District Prosecutors’ Office said five of the trucks were already sold at auction in August for more than $270,000 in an attempt to hamper the “industrial chain” of environmental crimes.
Speculation around the motive for the alleged dumping highlights a potential avoidance of waste processing fees, the District Prosecutors’ Office told local media.
In 2024, the District Prosecutors’ Office set up its “black water task force” following a spate of illegal dumping incidents.
