Bypass pumping is a necessary element of many sewer rehabilitation projects. As sewer infrastructures continue to age, timely rehabilitation is oftentimes required to keep it running smoothly. Temporary bypass pumping systems are used to transfer water supplies and the flow of sewage in order to prevent infrastructure downtime during construction.
What is bypass pumping?
Bypass pumping is the act of pumping sewage around a section of sewer line in pipe or channel specifically constructed for the purpose of bypass. Bypass pumping allows the repair or replacement of a section of sewer or infrastructure without causing mess or spillage on public or private property and without affecting the flow of sewage or water in the immediate or surrounding areas while repairs are underway. There can be numerous problems when trying to keep these areas open during work.
When existing sewer lines are rehabilitated, the flow of sewage typically cannot be diverted as simply as one might imagine; it must be bypassed – or temporarily pumped around the section of pipe to be repaired or replaced. In order to do this, pumps and equipment capable of pumping trash and sewage-laden effluent must be used.
Bypass pumps are installed upstream of the faulty pipe. A temporary pipeline is then installed from the pumps downstream of the pipe requiring repair or maintenance. The bypass pipe will then be merged with regular sewer lines downstream until the repair work is complete. Temporary plugs are also set into place between these points to allow for removal or repair.
There are many factors that determine the proper pump and equipment required. Depending on the businesses or homes serviced, the bypass line may handle pumping from a few hundred to a few thousand gallons per minute.
Why is bypass pumping important?
Billions of dollars in federal money has been set aside for the rehabilitation of decaying sewer systems. With a large amount of infrastructure work needed in the USA, many problems can arise when work is performed around existing structures such as roads, buildings, waterways, homes, and businesses. Bypass pumping can remedy these problems.
Note: A properly trained and licensed bypass pumping company should be selected to perform the work. Your bypass contractor will need to know the following information in order to provide a bypass pumping solution:
- Peak flow
- Sewer line pipe size
- Sewer line pipe depths
- Duration of the work
- Site access issues
