Toxic and harmful wastewater from chemical enterprises should be transported through overhead pipelines, so that leaks can be detected promptly and maintenance can be carried out in a timely manner to prevent pollution. Open ditches are preferable for rainwater drainage; it is best to install large-diameter, leak-proof drainage ditches around the facility. It should have sufficient capacity to collect rainwater, facilitating pollution monitoring. It is released into water bodies only after confirming there is no contamination.

The drainage ditches in chemical plants are generally underground; I’ve never seen any plant use above-ground ditches as drainage systems Whether it’s toxic or not, open ditches cannot be used for aesthetic reasons! It is even less possible to use open ditches for discharging toxic wastewater; if that were the case, the volatile toxic gases would kill people.
Here, we use underground pipes for rainwater, while sewage pipes run above ground.
Haha, I’m talking about rainwater drains. It’s not about wastewater discharge. Pipes for rainwater, when installed above ground, are relatively safer. Yes, some companies, in order to reduce costs, or for aesthetic reasons, or due to traditional thinking patterns, make extensive use of rainwater drains or underground channels. However, I have seen that many chemical and steel enterprises, both domestic and international, use open ditches for rainwater drainage, and this approach is quite noteworthy
The biggest flaw of underground drainage systems is that the levels of pollutants in the runoff water exceed acceptable limits, and this cannot be detected or controlled; or perhaps no efforts are made to conduct such detections at all. This practice ends up harming nearby water bodies and threatening environmental safety, especially during light to moderate rainfall
Here, we use buried rainwater pipes, with rainwater wells installed intermittently as needed.
Rainwater drainage through pipes is the most common method of drainage used in China. However, its drawbacks are obvious: heavy rain leads to poor drainage, resulting in large areas of water accumulation on roads, and it is difficult to detect pollution in a timely manner
Whether it is open ditches or covered ditches, rainwater and wastewater must be treated separately: rainwater is discharged directly from the facility, while wastewater is sent to a wastewater treatment plant for processing. We all use hidden ditches
