A pump station that’s old doesn’t need to stop operating to become a source of concern. The pump station may be able to transport water or wastewater throughout the day but struggle when the demand is high. It may require regular maintenance or rely on controls that are challenging to maintain. While the equipment is operating the original design may not be adequate for today’s conditions.
Understanding this distinction is crucial for the municipalities, developers and facility operators when planning improvements to infrastructure.

You should look past the equipment that’s not working properly.
Retrofitting a wastewater lift station should begin with an assessment of the complete system, not just the pump which is experiencing difficulties. Engineers should evaluate the water well, the mechanical equipment as well as electrical components, control systems, discharge pipes, as well as the current needs for pumping.
It is essential to observe the state of the wet well. It could be possible, when the structure is solid, to keep it and replace outdated equipment. It’s less expensive to build a new station than you decided to preserve the current one. It is essential to preserve existing infrastructure if the improvements are possible.
Has the Service Area been changed?
A wastewater station designed decades ago could now be serving additional homes, commercial buildings, or industrial operations.
These modifications can alter flow rates and operational requirements. Rehabilitation of a lift station requires more than just the restoration of original specifications for equipment. Engineers should evaluate the future and planned flows as well as the equipment’s capacity and dependability.
A larger pump isn’t automatically the answer. The new machine must be compatible with the current piping system as well as electrical power supply and control. If you improve one component you can create problems with other parts of the system.
Stormwater Retrofits Have Different Priorities
A stormwater pump station retrofit introduces additional considerations because runoff can change dramatically with rainfall and surrounding development. The flow pattern at stations that serve an area for detention could differ from one that gets water directly from the storm drain. Any changes to drainage infrastructures, such as new pavement or expanded parking lots, may affect the frequency and quantity of water that is capable of reaching the station.
Before recommending an upgrade to a stormwater station, engineers must analyze the drainage areas contributing to the stormwater system and peak flows anticipated as well as the capacity of storage available as well as discharge conditions and pump performance.
The results of these studies can help decide the degree of modernization needed or if a station requires more extensive reconstruction.
Plan the Construction Before Interrupting Service
How the station will operate in rehabilitation is a subject which is frequently ignored. The wastewater system is generally not disconnected without the need for continuous flow management.
Construction can include temporary bypass pumps or the construction of a new infrastructure with an operating station in accordance with the space available and the specific requirements of the project.
The stormwater project also requires careful scheduling since the system might be needed during unexpected rainfall. A complete engineering plan should be able to address installation sequence the temporary operation, the integration of equipment, and commissioning, not just the replacement parts.
Making the completed system simpler to use
Romtec Utilities is a provider of site-specific engineering supply and solutions for Stormwater and Wastewater Pumping Applications.
Retrofitting is a process that evaluates structural, mechanical electric, and communications components to determine which are best kept and which should be replaced. The company offers owners preliminary designs, estimates of budgets and options for projects.
After installation, the tests of startup, commissioning and operator training are crucial to ensure that the newly upgraded station is functioning according to the specifications. The successful rehabilitation projects will provide operators with an easy-to-maintain system.
Upgrade Your System and Not Limit Its Upgrades to the Age
It’s not necessary to replace an older pump station. Some structures may have years of use left even when their mechanical and electrical equipment is in need of modernization. The important decision is identifying what is safe and economically, while also ensuring that the completed station is able to meet current and future demands.
Owners are able to make better investment choices by examining the operational conditions as well as structural integrity and hydraulic requirements together.
It’s not only about making the old station operational. The goal is to ensure that the newly upgraded system can be able to handle the work that is coming up.
