A pump station that is older doesn’t have to stop working in order for it become a concern. It may still move water or wastewater every day, yet struggle during the peak times, require frequent maintenance or rely on controls that are becoming difficult to support. While the equipment is operating but its original design might not be suitable for the current climate.
The planning of infrastructure improvements is crucial for city officials, developers and managers of facilities.

It is important to look beyond the equipment that is failing
The retrofit of a water liftstation should begin by assessing the whole system, not just the pump. Engineers should examine the wetwell as well as mechanical equipment as well as electrical components, drain piping, controls and current requirements for pumping and control systems.
It is vital to pay attention to the state of your wet well. If its structure is in good condition, it may be suitable to keep it even when replacing equipment that is no longer in use. It can be less expensive to build a new station than if you kept the current one. It is crucial to maintain existing infrastructure in case improvements are possible.
Have the areas of service changed?
A wastewater plant that was built many years ago can now provide other commercial or residential properties, homes or industrial activities.
These modifications could alter flows and operational demands. Rehabilitation of a lift station requires more than just the restoration of original specifications for equipment. Engineers must assess the their current and future flows, head dynamics, equipment capacity, and operational reliability.
A bigger pump may not be the solution. The new pump must be compatible with the current piping system along with electrical and mechanical supply as well as controls. In the event that one component is improved, it can create problems elsewhere.
The priorities for retrofitting stormwater systems are different
Retrofitting an existing stormwater pumping station can introduce additional considerations because runoff is influenced by the surrounding development and rain. The pattern of inflow at a station that serves a detention area may be different than if it receives water directly through the storm drain. Any changes to drainage infrastructures, such as new pavements or the expansion of parking areas, could affect the timing and amount of water able to reach the station.
Before recommending a stormwater station upgrade, engineers should review the contributing drainage area, expected peak flows, storage capacity, discharge conditions, and existing pump performance.
The information will help determine if your station needs to be rebuilt or whether modernizing the equipment is enough.
Design the Construction Before Interrupting Service
The most often overlooked concern is how the current station will function during the rehabilitation. The general rule is that wastewater systems can’t be shut down without a plan to control flow.
Based on the space available and project requirements, construction may involve temporary bypass pumps or the installation of replacement infrastructure alongside the operating station.
The stormwater project also requires careful scheduling because the system may require maintenance during rain events that are unexpected. The engineering plans must include the installation sequence, temporary operations and equipment integration.
The final System is easier to Operate
Romtec Utilities provides site-specific engineering and supply solutions for wastewater and stormwater pumping needs.
Retrofitting is a process that evaluates structural, mechanical, electrical, and communications components to determine which are best left and which needs to be replaced. The company gives owners preliminary designs, estimates of budgets and project alternatives.
After installation, initial testing and commissioning will be conducted in conjunction with operator training and documentation. Operators should be able to keep the station operating and comprehend it after a successful rehabilitation project.
Upgrade the System, Not Only Its Age
An older pump station isn’t necessarily a candidate for a complete overhaul. Some structures may have decades of useful service remaining, even when their electrical and mechanical equipment needs modernization. The important decision is identifying the things that can be kept safely and economically, while also ensuring that the final station can meet both current and future demands.
Through analyzing operating conditions, the structural strength, hydraulic requirements and construction restrictions together owners can make better informed investment decision.
The objective isn’t to make a stale station function again. It’s to ensure that the new system is ready to handle the challenges ahead.
