How can liquid in underground pipes be brought to the surface without a pump?
Thread Content
The company has an underground sewage tank, and construction to expand it will take at least a month. Therefore, they plan to install a storage tank on the surface as a temporary place to hold the sewage. The sewage from the existing tank can be pumped up directly. The problem now is that there are several sources of sewage, all through underground pipes; how can this sewage be directed to the storage tank on the surface during the construction period? Since the flow rate in the pipes is low, pumps cannot be used, and it’s not practical to use buckets manually. So what should be done?
From underground to the surface, it is a change in potential energy, and work must be done. Obviously, a pump is the best choice. I don’t know why a pump can’t be used; a small submersible pump with low flow rate will do, as long as it’s turned on from time to time. Or find a way to create a vacuum in the above-ground tank, then connect a pipe from the above-ground tank to a point below the liquid level in the underground tank, using the vacuum to draw the liquid out. A vacuum pump is also a pump.
Only a pump, or a vacuum pump, can be used.
1. Find ways to recycle the source of wastewater, so that it doesn’t end up in the sewage tank. 2. Utilize the difference in elevation by connecting the wastewater pipes to a temporary tank; generally, the sewage tank is located at the lowest point of the entire facility. 3. If the grade difference isn’t sufficient, a pump is the only option
Using a submersible pump temporarily is the most convenient option. But be careful with electrical safety
It’s completely possible without a pump; a vertical water wheel or a pulley can be used. It’s likely the original poster has never seen a tool like this for transporting water from a lower to a higher place. It’s great that no pump is needed; water wheels or pulleys are environmentally friendly and give off a sense of cultural heritage.

Use temporary submersible pumps, or connect a portable air pump, also known as a water pump truck
I’m just checking to see if there’s a windwell
