A pump station that is old doesn’t need to stop functioning to be a problem. It might still be able to move water or wastewater every day but struggle to meet high demand, require more frequent maintenance or rely on control systems that are becoming increasingly difficult to sustain. It might still function however, the original model of the equipment may not be a good reflection of current conditions.

Developers, municipalities, and facility operators, recognizing the distinction is an important part of planning improvements to infrastructure.

Look Beyond the Equipment That’s Broken

The retrofitting of a wastewater liftstation should begin by looking at the whole system, not only the pump. Engineers should examine the wetwell and mechanical equipment as well as electrical components, drainage pipes, controls as well as the current requirements for pumping and control systems.

It is essential to be aware of the state of your wet well. It might be possible when the structure is in good condition to preserve it and replace outdated equipment. This will reduce the amount of construction needed when compared to building a completely new station. Retaining existing infrastructure is only worthwhile when it is in line with the planned improvements.

Did the area of service change?

An old wastewater facility could be serving additional residential, industrial or commercial buildings.

These changes can affect flows and operating demands. Successful lift station rehabilitation therefore requires more than restoring the original equipment specifications. Engineers must evaluate the flow of current and anticipated flows in the system, the dynamic head of equipment as well as operational reliability and the capacity.

It’s more than enough to purchase a bigger pump. New equipment should work with the existing system of piping, wet wells, electrical supply, controls etc. If one component is upgraded the result could be problems with the other components.

Priorities for stormwater retrofits are different

Retrofitting an existing pumping station for stormwater can introduce additional considerations due to the fact that the runoff can be affected by nearby development and rain. The flow pattern of an area that has a detention area may be different from if it is receiving water directly through the storm drain. New pavements, expanded parking areas, or altered drainage infrastructure could also alter the quantity and frequency of runoff entering the station.

Before recommending a stormwater station upgrade, engineers should review the drainage area that is contributing to the project the anticipated peak flows, storage capacity, discharge conditions, and the current pump performance.

These findings can help determine whether modernization of the equipment will suffice or if the station requires more extensive reconstruction.

Plan Construction Before Interrupting Service

How the station will operate during rehabilitation is a question that is often ignored. The wastewater system is generally not disconnected without the need to ensure that flow control is maintained.

Based on the available space and project requirements, construction may involve temporary bypass pumping or replacement infrastructure alongside the operating station.

The system might be required during an unexpected downpour. The engineering plan must include the installation sequence along with temporary operations, equipment and integration.

Making the final system easier to use

Romtec Utilities provides site-specific engineering and supply solutions for stormwater and wastewater pumping needs.

Retrofitting is a technique that evaluates structural, mechanical electrical, and communications components to determine which components can be left and which needs to be replaced. The company offers owners preliminary designs, estimates of budgets as well as project options.

Following installation, tests for startup and commissioning will be conducted and then followed by training for operators and documentation. Operators need to be able keep the station operating and comprehend it after a successful rehabilitation.

Upgrade the System, Not Only Its Age

A pump station that is older may not need to be completely replaced. It’s possible that some structures will be functional for many years, even if the mechanical and electrical systems require modernization. The most important thing is to figure out what can be safely and effectively preserved while ensuring the station meets current as well as future needs.

When examining operating conditions structural integrity, hydraulic requirements as well as construction constraints owners can make better informed investment choices.

The goal isn’t simply to make an old station perform again. It’s about making sure that the new system is ready for the task ahead.
