An old pump station isn’t required to shut down before it becomes a problem. Even though it may transport stormwater and wastewater on a daily basis, the pump station might struggle to keep up with the demand for water at its peak. It could also require more regular maintenance. Although the equipment is still being used, its original design might not be suitable for the current climate.

For municipalities, developers, and facility operators, recognizing the difference is an essential element of planning for infrastructure improvements.
See beyond the equipment Failing
A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers must evaluate the wetwell, the mechanical equipment, as well as electrical parts. They should also look at discharge piping as well as the needs of current pumping.
The condition of a well is extremely important. It could be possible, in the event that the structure is sturdy in its current condition, to maintain it and then replace the outdated equipment. This could reduce the construction costs compared with building an entirely new station. However, retaining the existing infrastructure is only a good idea in the context of enhancements that are planned.
Did the area of service change?
A water treatment plant built a few years ago may now serve more commercial and residential buildings, homes, or industrial operations.
These modifications could affect the rate of flow and operational needs. For lift stations to be successfully rehabilitated, it is not enough to revert back to original specifications. Engineers should evaluate the flow rates and expected flow rates as well as the equipment’s capacity and performance.
A larger pump isn’t automatically the solution. The new pump must be compatible with the current piping system, electrical supply and controls. If not, enhancing one part could cause problems in other areas.
Priorities for stormwater retrofits to be different
Retrofitting a stormwater pump station requires additional considerations as runoff patterns can be affected by rain and nearby development. The flow pattern of the station that is serving the area of detention may differ from one that gets water directly from the storm drain. New pavement, expanded parking areas, or altered drainage infrastructure could also alter the frequency and amount of runoff reaching the station.
Before recommending a new stormwater system, engineers need to analyze the drainage areas contributing to the stormwater system including peak flows expected in the future, storage capacity that is available as well as discharge conditions and the pump’s performance.
These results can be used to determine whether modernization of equipment is enough or if the station requires more substantial reconstruction.
Make sure you plan your construction prior to when you interrupt service
The operation of the station during rehabilitation is frequently ignored. In general, wastewater systems cannot be removed without a proper plan to manage flow.
Construction can involve installing temporary bypass pumps, or relocating infrastructure that is adjacent to the station operating.
Stormwater projects also require a careful planning as the system might be needed in the event of an unexpected rainstorm. The engineering plans must include the installation process, temporary operations and equipment integration.
Create the Final System Simpler to Use
Romtec Utilities is a provider of engineering services for sites as well as supply and solutions for Stormwater and wastewater Pumping Applications.
The retrofit method will determine which electrical, structural mechanical and communications components will be preserved and which ones need replacement. The company also offers initial designs and budgetary estimates to help owners evaluate project alternatives.
After installation, startup testing and commissioning will be conducted and then followed by training for operators and documentation. A successful rehabilitation program should provide operators with a system they can manage and comprehend.
Upgrade Your System, Not Only the Age
It’s not necessary to replace an old pump station. Even if the electrical and mechanical equipment is outdated Some structures may be of use for a number of years. It is essential to identify the things that can be maintained safely and economically, while still ensuring that the station’s finished product is in line with current and future requirements.
Owners are able to make better investment choices by looking at the conditions of operation, structural integrity and hydraulic needs together.
The goal of upgrading an old system is not just to fix it again. It’s to ensure that the new system is well-equipped for the task ahead.
