How exactly should rainwater and sewage be separated in the plant area? There are drainage ditches in the plant area, which are used to collect wastewater from the cleaning processes; however, rainwater also mixes in when it rains, and the volume of water is particularly large during heavy storms How exactly is separate collection of rainwater and wastewater implemented? How does your factory handle this? Are there any good practices you can recommend?
Here, the rainwater wells and sewage wells are not part of the same system, so the discharge can be controlled
It’s quite simple: two separate buried pipeline systems are set up. However, for waste water from flammable and toxic substances (such as those in tank areas), valves must be installed to connect these waste water streams to either the sewage or rainwater pipelines. Initial rainwater is directed into the sewage pipeline, while later-stage rainwater is sent to the rainwater pipeline
