A pump station that is not in good condition doesn’t necessarily need to stop working in order for it be a problem. Even though it is able to transport stormwater and wastewater daily, the pump station might struggle to cope with the demand for water at its peak. It might also require more frequent maintenance. It may still work however the original design of the equipment may not be a reflection of the current situation.
Recognizing this difference is important for municipalities, developers and facility managers when planning upgrades to infrastructure.

You must look beyond the equipment not working properly.
A wastewater lift station retrofit must begin with an evaluation of the entire system, not just the pump that is experiencing issues. Engineers should evaluate the wetwell, mechanical equipment and electrical parts. They should also look at discharge piping and the current needs for pumping.
The state of the well is vitally important. It could be possible, if the structure is sound to preserve it and upgrade the equipment. This can reduce construction requirements as compared to the construction of a new station. Retaining existing infrastructure is only worthwhile as long as it helps the improvements being proposed.
The area of service has been changed.
An old wastewater station may serve additional residential, industrial or commercial properties.
These changes may affect the rate of flow and operational needs. Successful lift station rehabilitation therefore requires more than restoring the original equipment specifications. Engineers should evaluate the current and anticipated flows, as well as the equipment’s capacity and performance.
It’s more than enough to buy a bigger pump. New equipment must work alongside existing piping systems and wet well, as well as the electrical supply, and controls. When one part is upgraded, this can lead to problems with other parts.
Priorities for stormwater retrofits are different
A stormwater pump station retrofit involves additional considerations since runoff can change dramatically in response to rainfall and the development around. The flow pattern at the station that is serving an area for detention could be different from if it gets water directly from the storm drain. The amount of runoff that reaches the station could be affected by new pavements in addition to parking space, or changed drainage infrastructure.
Before recommending a stormwater pump upgrade, engineers should examine the contributing drainage area the anticipated peak flows storage capacity, discharge conditions, and the current pump performance.
The findings will help you determine if the station requires to be rebuilt or if modernizing equipment is sufficient.
Plan Construction Before Interrupting Service
The most often overlooked concern is how the existing station will function during the rehabilitation. It is impossible to close down the wastewater systems without making arrangements for flow control.
Construction may include installing temporary bypass pumps or the replacement of infrastructure near the operating station.
Stormwater projects also require careful scheduling due to the fact that the system could be needed during unexpected rainfall. The engineering plan must include the installation sequence along with temporary operations, equipment and integration.
Create the Final System easier to operate
Romtec Utilities provides site-specific engineering and supply solutions for wastewater and stormwater pumping requirements.
The company’s retrofit strategy identifies the structural, mechanical, electrical, and communication elements are able to remain in place and which need replacement. The company gives owners initial plans and estimates of budgets for them to evaluate their project options.
After installation, testing the startup, commissioning and operator training are crucial to ensure that the upgraded station is performing in accordance with its specifications. Operators need to be able maintain and understand the system after a successful rehabilitation project.
Improve the System, Not Just Its Age
An older pump station isn’t necessarily a candidate for complete replacement. Even if their electrical and mechanical equipment is outdated Some structures may remain useful for a long time. It is crucial to decide the things that can be maintained safely and economically, while still ensuring that the station’s finished product is compatible with future and current requirements.
When examining operating conditions the structural integrity, hydraulic requirements and construction restrictions together owners can make informed investment decisions.
The objective of upgrading an old system is not just to fix it again. The aim is to make sure that the new system is able to handle the upcoming work.
