Sewer pumping stations are also known as lift stations. These stations are used to transport wastewater to higher places in order to permit transport by the flow of gravity. Sewage is therefore fed into and directed into an underground pit that is called a wet well.
When the level of sewage rises to a certain level, a pump is started to lift the sewage through a system of pressurised pipes. From there, it is eliminated into a manhole. The cycle starts from there once more. Therefore, pumping stations that collect sewage are constructed to manage raw sewage that is fed from gravity pipes underground.
When Pumping Stations Are Used
Usually, the need for these types of stations occurs when:
- The current topography and necessary minimum sewer grades produce sewers that cost a lot to construct. That is because the sewage is elevated and conveyed with the help of gravity.
- Basements are located too low to emit sewage to the main sewer line.
- The sewage must be transported across a ridge.
- The sewage must be raised to gain gravity flow for treatment at a plant.
- The discharge outlets are beneath the level of the receiving waters.
- A current gravity system is not currently available. Therefore, the pumping station will assist in the development of a community’s plan for sewage transport.
Adoptable Pumping Stations
The use of adoptable pump stations meets certain regulations and guidelines of water companies. Whether you happen to be a housing developer, property, owner, or civil contractor, you can have a pumping station installed by a company that offers emergency breakdown assistance as well.
Reducing Pumping Issues
The sewage pump is usually an end-suction centrifugal pump that features open impellers and an open passage, meant to avoid clogs. Some of the common problems associated with the pump include siltation, blockages, or fat buildup. To reduce siltation, a wet well flushing system is supplied. Any fat accumulation can be reduced by using an ultrasonic unit’s facilities and by establishing a range of top water levels for pumping starts.
Sewer system technology, as is noted by the use of a pumping station, always offers a high level of hygienic quality. If the sewage is directed in a closed environment and can be transported to higher elevations, it makes the operation safer and more secure. To avoid the overflow of a wet well, it is essential to construct a treatment plant at the end of each sewer system in this type of design.
The working principle of a pumping station involves the feeding of sewage into a sealed pit or wet well. When the level rises to a certain point, the pump directs the sewage higher through a pressurised system of pipes, all where it is emitted into a gravity manhole. This type of system is especially recommended for its high performance and reliability.
