It’s not necessary for a pump station’s stoppage in functioning to be a problem. The pump station might be able to handle the flow of wastewater or stormwater every day however, it may struggle when demand is high, require more frequent maintenance or depend on controls that are difficult to maintain. It may still work however, the original design of the equipment might not be a good reflection of current conditions.
For municipal governments, developers and facility operators, acknowledging the differences is a crucial aspect of preparing infrastructure improvements.

You must look beyond the equipment that is inoperable
The retrofitting process of a wastewater lift station should start by evaluating the entire system, and not only the pump. Engineers should evaluate the wetwell, mechanical equipment and electrical components. They should also look at discharge piping and current pumping needs.
The state of the wet well is vitally important. If the structure is sound it might be possible to retain it as a replacement for outdated equipment. It’s less expensive to build the new station than you kept the current one. Retaining the existing infrastructure is only beneficial when it is in line with the changes being planned.
The service area has changed.
The wastewater station that was constructed a few years ago is now able to be used to provide services to many more households, businesses and industrial facilities.
These changes may affect the flow rate as well as operating needs. To ensure that lift stations are successful in rehabilitation, it’s not enough to restore the original specifications. Engineers should assess future and planned flows as well as the equipment’s capacity and reliability.
A larger pump isn’t automatically the answer. The new equipment must be compatible with the existing pipes, electrical supply and controls. If you improve one component the problem could be with other parts of the system.
The criteria for stormwater retrofits for priority are different
A stormwater pump station retrofit introduces additional considerations because runoff can change dramatically with rainfall and surrounding development. A station serving the detention pond could experience distinct inflow patterns compared to one receiving water directly via storm drains. The amount of runoff that gets to the station can be affected by new pavement and parking spaces, or the alteration of drainage infrastructure.
Before recommending a change to a stormwater pump station engineers must examine the drainage area that is contributing to it. They should also examine the potential peak flows storage capacity, discharge conditions.
The results will help you determine if the station requires to be reconstructed, or what the best option is to modernize equipment.
Design the Construction Before Interrupting Service
The most often overlooked concern is how the station will be operating during rehabilitation. It is impossible to stop the wastewater system without making arrangements for flow management.
Based on the space available and project requirements the construction could involve temporary bypass pumping or new infrastructure in conjunction with the operating station.
The system might be required in the event of an unexpected downpour. The engineering plan must include the sequence of installation along with temporary operations, equipment and integration.
The final System is much easier to use
Romtec Utilities provides site-specific engineering and supply solutions for wastewater and stormwater pumping needs.
Retrofitting evaluates structural, mechanical, electrical, and communications components to determine which components can be kept and which should be replaced. The firm provides owners with preliminary designs, estimates of budgets as well as project options.
After installation, the tests of startup, commissioning and operator training are crucial to ensure that the upgraded station is performing according to its design. Operators should be able manage and comprehend the system following a successful rehabilitation.
Improve the System, Not Only Its Age
An older pumping station doesn’t mean it’s a perfect candidate for a complete overhaul. Even if their electrical or mechanical equipment is old-fashioned there are some structures that can be beneficial for years to come. It is crucial to decide what can be kept safely and cost-effectively, while ensuring that the station’s finished product will meet future and current requirements.
Owners can make better investment decisions by reviewing the operating conditions along with structural integrity, hydraulic and requirements in conjunction.
The aim in upgrading an older station isn’t to just make it function again. It’s about ensuring that the system that has been upgraded is properly prepared to handle the challenges ahead.
