A pump station that’s old shouldn’t be forced to cease functioning to become a cause for concern. It can still transfer water, or even stormwater, every day, yet struggle during periods of high demand, need frequent maintenance, or rely on controls that are becoming difficult to maintain. The equipment functions, however the design it was originally designed for may not reflect the current conditions surrounding it.

It is vital to recognize this distinction for municipal officials, developers and facility managers in planning improvements to infrastructure.
The Equipment that is failing isn’t the sole issue
A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers should assess the mechanical and wetwell components as well electrical components, controls, drainage piping, current pumping requirements, and control systems.
The state of the wet well is of particular importance. It may be possible, in the event that the structure is sturdy, to keep it and then replace the outdated equipment. Costs of construction can be reduced compared to building a brand new station. Retaining the existing infrastructure is only beneficial as long as it helps the planned improvements.
Is the service area changing?
A wastewater facility that was constructed many years ago can now provide more commercial and residential buildings, homes or industrial facilities.
These modifications can impact flow rates and operating demands. A successful rehabilitation of a lift station is more complicated than simply restoring the original specifications for the equipment. Engineers must evaluate the current and expected flows as well as the dynamic head of the equipment as well as operational reliability and the capacity.
The answer may not be to get a larger pump. The new equipment should be compatible with the existing pipes, electrical supply and controls. When one part is upgraded, this can lead to problems with other parts.
The priorities for retrofitting stormwater systems are different
Retrofitting an existing pumping station for stormwater could result in additional challenges due to the fact that runoff is influenced by surrounding development and rainfall. The flow pattern of stations that serve a detention area may be different than if it is receiving water directly through the storm drain. The amount of runoff that gets to the station may be affected by new pavements, increased parking, or altered drainage infrastructure.
Before recommending an upgraded stormwater pump, engineers should review the contributing drainage areas including peak flows expected in the future, storage capacity that is available, discharge conditions and the performance of the pump.
The results of these studies can help decide the degree of modernization needed or if a station requires greater reconstruction.
Design your project before you interrupt service
The operations of the station in rehabilitation is often overlooked. Systems for managing wastewater generally can’t be taken offline without arrangements for ongoing flow control.
Based on the available space and project requirements The construction process may include temporary bypass pumping, or even installing new infrastructure adjacent to the operating station.
It is equally important to think ahead about stormwater projects since the system may be needed during unexpected rainstorms. A complete engineering plan should address installation sequencing the temporary operation, integration of equipment and commissioning not just the replacement of components.
The finished System is more user-friendly
Romtec Utilities offers site-specific engineering solutions and supplies for stormwater and wastewater pumps.
Retrofitting is a process that evaluates structural, mechanical, electric, and communications components to determine what can be left in place and which need to be replaced. The company offers owners preliminary designs and budget estimates to help them evaluate the options for their project.
After installation, the testing of startup Commissioning, operator training as well as operation and maintenance documentation will ensure that the newly upgraded station operates as per its specifications. Operators should be able manage and comprehend the system after a successful rehabilitation project.
Upgrade the System, Not Only Its Age
It’s not required to replace an older pump station. There are some structures that have years of reliable service, even when their electrical and mechanical equipment is in need of modernization. The key is to determine what is safe and economically while ensuring the constructed station meets current and future demands.
Owners can make better investment decisions by looking at the operational conditions as well as structural integrity and hydraulic requirements together.
The purpose of upgrading an old station is not to just make it function again. It’s about ensuring that the new system is ready for the future work.
