Should the sewage discharge and collection pipelines be installed as open pipes?
Thread Content
Previously, our sewage pipelines were buried underground; after many years, it was discovered that there were problems with these pipelines – some sections of them were damaged, preventing sewage from flowing properly to the treatment plants. As a result, repairing the underground sewage network is very troublesome and yields poor results. Later, new pipelines and collection tanks were installed for the wastewater in some areas; after operating them for a while, it was found that the results were good, and leaks in the pipelines were easy to detect and address promptly. Therefore, it was decided to abandon the existing underground sewage pipeline network, backfill it completely, and reinstall the sewage discharge pipes and sumps in each section, thereby avoiding environmental risks. Let’s discuss it – has anyone encountered such a problem on site? How to deal with it?
A few years ago, our factory also wanted to do this, but nothing has been accomplished to date.
After some preliminary testing over a period of time, we are now starting full-scale implementation. The main implementation involves setting up on-site sewage collection tanks in the area and installing pipeline transportation systems.
So, I have a question: can the drainage pipes that have been treated by a wastewater treatment plant be buried underground?
From what we have here, it’s possible. Because at the discharge points for wastewater treatment, environmental supervision agencies have installed online monitoring systems, so the possibility of illegal discharges is essentially zero; P
The scale of this renovation project is truly enormous. Whether to use buried pipes or above-ground pipes should be determined based on local conditions; there are many factors to consider, and the decision should be made based on what is most suitable, rather than adopting a one-size-fits-all approach. As for the leakage issue of buried pipes, the key is to ensure high quality in project construction; most chemical plants (or industrial parks) rely on buried pipelines.
Sewer pipes are generally laid underground. Indeed, there are the engineering quality issues you mentioned. These days, wastewater management includes flow monitoring and parameter monitoring; in addition, inspections of soil quality are also carried out. As a result, it has become necessary to manage leaks in underground pipelines: lol. That’s why many production sites simply switch their wastewater pipelines to above-ground ones
A unit that had been in operation for 15 years was once upgraded; after excavating the foundation, it was found that the ground below consisted of dark, sludge-like material, indicating severe pipe leaks and significant contamination of the underground environment.
