A pump station that’s old shouldn’t be forced to cease functioning in order to become a concern. The pump station may be able to handle the flow of wastewater or stormwater every day but have trouble when demand is high, need more frequent maintenance or rely on controls which are difficult to maintain. While the equipment is being used however, the design it was originally designed for may not be suited to today’s conditions.

Recognizing this difference is important for developers, municipalities and facility operators when planning upgrades to infrastructure.
Find the equipment that’s Not Working
A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers should evaluate the water well, mechanical equipment as well as electrical components, control systems, discharge pipes, as well as the current needs for pumping.
The condition of a well is extremely important. If its structure is solid it is possible to retain it when replacing equipment that is no longer in use. The construction costs could be lower when compared to the construction of a new station. It is important to keep the existing infrastructure even if improvements can be made.
The area of service has been changed.
An old wastewater station may be supplying additional residential, industrial or commercial buildings.
These modifications could have an impact on flows and operational demands. To ensure that lift stations are successful in rehabilitation, it’s not enough to restore the original specifications. Engineers should evaluate their current and future flows, head dynamics, equipment capacity, and the reliability of operation.
A bigger pump may not be the solution. The new equipment should be compatible with existing piping, electrical supply and controls. When one part is upgraded, this can lead to problems with other parts.
Retrofits to stormwater have different priorities
Retrofitting a stormwater pump station involves additional considerations since the runoff may change drastically with rainfall and surrounding development. A station that is connected to an detention pond may have different inflow patterns from one receiving water directly via storm drains. Any changes to drainage infrastructures like new pavement or larger parking spaces, could alter the timing and amount of water that is capable of reaching the station.
Before recommending an upgrade to a stormwater pump station engineers should review the drainage area in which they are contributing. They should also examine the anticipated peak flows as well as storage capacity and discharge conditions.
The data will allow you to determine if the station needs to be rebuilt or if modernizing equipment is sufficient.
Plan Construction Before Interrupting Service
One of the most frequently ignored issues is how the station will function during rehabilitation. It is impossible to stop the wastewater system without making arrangements for flow control.
Construction can involve installing temporary bypass pumps or even replacing the infrastructure surrounding the operating station.
The system could be required for an unexpected rainstorm. A plan for engineering that is comprehensive should include the sequencing of installation, temporary operation installation, equipment integration and commissioning, not just replacement components.
Make the Finished System Simpler to Use
Romtec Utilities offers site-specific engineering solutions and supplies for stormwater and wastewater pumps.
The retrofit process will determine which electrical, structural mechanical and communications components should be kept and which ones need replacement. The company offers owners preliminary plans and estimates of budgets to assist them in evaluating their the options for their project.
After installation, startup testing and commissioning are conducted and then followed by training for operators and documentation. Operators should be able to keep the station operating and comprehend it following the successful rehabilitation.
Upgrade your system, not just your system’s age
A pump station that’s older might not need to be completely replaced. It is possible that some structures will continue to be functional for a long time even if mechanical and electrical systems need modernization. The key is to identify what is safe and cost-effectively retained while making sure the station is able to meet current and future requirements.
When examining operating conditions structural strength, hydraulic requirements and construction constraints together owners can make better informed investment decision.
The purpose in upgrading an older station isn’t just to fix it again. It’s about ensuring that the new system is well-equipped for the task ahead.
