Professional Bypass Pumping Services & Flow Control for Sewer Networks
Almost any planned works on a live sewer or water network, from relining and repairs to structural upgrades, depends on safely diverting flow around the work site. Get it wrong and you risk overflows, environmental harm and project delays. Veolia delivers bypass pumping and flow control for projects large and small, keeping networks operating while critical works are carried out.
With an in-house pump fleet, our own power generation and specialist crews, backed by 170+ years of global water expertise, we design and run reliable temporary flow solutions that protect your assets, the public and the environment.
What is Bypass Pumping and Flow Control?
Bypass pumping (also called over pumping) temporarily diverts flow around a section of pipe or a structure so that it can be isolated, inspected, repaired or replaced. Pumps draw flow from upstream, move it through temporary pipework or hoses, and discharge it back into the network downstream of the work area.
Flow control is the broader discipline of managing flows during works, which can include plugging and stopping flows, throttling or storing flow, and combining pumping with tanker services during peak periods. A well-engineered bypass and flow control plan keeps the network live and compliant throughout the works window.

The Importance of Bypass Pumping
Bypass pumping and flow control underpin a wide range of network activities, including pipe relining and rehabilitation, structural repairs and upgrades, pump station maintenance and refurbishment, emergency response to collapses or blockages, and any planned works where a live sewer or main must be temporarily taken out of service without interrupting the network.

What is the difference between bypass pumping and flow control?
Bypass pumping specifically diverts flow around a work area using pumps and temporary pipework. Flow control is the broader management of flow during works, which can also include plugging, throttling, storage and tanker support. We deliver both.
How large a flow can you handle?
Our in-house pump fleet ranges from small submersible and macerator pumps up to 12" diesel pumps, so we can scale to both minor diversions and major projects.
Do you provide your own power on site?
Yes. We own portable power generation to support bypass and flow control operations, which improves reliability and reduces dependence on third-party hire.
Can you support works out of hours or in emergencies?
Yes. Bypass pumping and flow control frequently support emergency response to collapses and blockages, as well as planned works, and our in-house fleet supports responsive mobilisation.
What are Lampe plugs used for?
Lampe plugs are used to stop or control flow within pipes during works. Our crews receive specialist training in the maintenance and use of Lampe plugs as part of our flow control capability.
