The bureau sets up a toll-free environmental complaint hotline 0800-777795 to provide
24-hour service, and conducts on-site inspections and handling operations. In 2022-
2023, it accepted 13 complaints from the public, including 7 complaints about air
pollution, 4 complaints about noise, 1 complaint about water pollution and 1 complaint
about waste. The bureau immediately handled the complaints after receiving them. All
the complaints in 2022-2023 have been closed.

2. Centralized sewage treatment

All CTSP parks have established a perfect rainwater and sewage diversion sewer
system, and the acceptance rate of industrial sewage in the park reaches 100%. The
wastewater is properly treated by the sewage treatment plant and discharged only

after it meets the national discharge water and environmental impact assessment
standards. The rainwater sewer system not only collects rainwater in public areas, but
also manufacturers must design rainwater collection pipelines when building factories,

and set rainwater discharge ports to be incorporated into the rainwater sewer system,
which will be discharged into the flood detention basin in the park and then merged into

the receiving water body. The Bureau also regularly arranges sampling inspection plans
for sewage and sewer systems in various parks to understand the system conditions and
ensure the normal water quality.

The sewage treatment plants in the park are all three-stage treatment systems, adopting
standard biological treatment units of activated sludge (AO biological nitrogen removal

system and contact aeration method adopted by Taichung and Houli sewage plants), and
adding chemical coagulation and physical filtration treatment units in subsequent units to
improve the treated water quality and reduce the impact on the bearing water body.

The operators of Zhongxing Park are mainly research and experimental industries, and
no process wastewater is generated. The laboratory wastewater from the manufacturers

in the park is cleared and treated by qualified manufacturers, and the domestic sewage
is brought into the sewage sewer of the park and transported to Zhongzheng Road
Sewage Treatment Plant for proper treatment and then discharged.
