It’s not hard for the pump station to stop functioning to be an issue. It may still move wastewater or stormwater every day, yet struggle during the peak times, require frequent maintenance or depend on controls which are becoming more difficult to sustain. The equipment functions, however its design may not be able to reflect the changing conditions surrounding it.

For municipal governments, developers and facility owners, being aware the distinction is an important element of planning for infrastructure improvements.
It is important to look beyond the equipment that’s not working properly.
A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers need to evaluate the water well, mechanical components and electrical components, as well as controls, discharge piping and the requirements for current pumping.
The state of the wet well is of particular importance. If its structure remains sound, it may be possible to retain it while replacing outdated equipment. This may reduce the need for construction as compared to the construction of a new station. Retaining existing infrastructure is only worth it when it is in line with the proposed improvements.
The service area has changed.
A wastewater plant that was built many years ago can now provide more homes, commercial buildings or industrial facilities.
The changes could impact flow rates and operating demands. Rehabilitating a lift station is more than just the restoration of original specifications for the equipment. Engineers should evaluate current and anticipated flows, head dynamics capacity of equipment, as well as the operational reliability.
It’s not enough just to purchase a larger pump. The new equipment must be compatible with the existing pipes as well as electrical power supply and control. If you upgrade one component the problem could be with other parts of the system.
Stormwater retrofits are a different matter.
Retrofitting an existing pumping station for stormwater may bring additional issues due to the fact that runoff is influenced by the surrounding development and rainfall. Stations that service detention basins may have different inflow patterns than those that receive water via storm drains. The quantity of runoff reaching the station is affected by new pavement and parking spaces, or altered drainage infrastructure.
Before recommending an upgraded stormwater station, engineers must analyze the drainage areas contributing to the stormwater system including peak flows expected as well as the capacity of storage available and discharge conditions, as well as the performance of the pump.
The results will help you determine if your station needs to be rebuilt or if the modernization of equipment is enough.
Design your project before you disrupt service
One frequently overlooked issue is how the existing station will function during the rehabilitation. The wastewater system is generally not disconnected without the need to ensure that flow control is maintained.
Construction can involve installing temporary bypass pumps or even replacing the infrastructure surrounding the station operating.
The stormwater project also requires careful scheduling as the system might be needed in the event of an unexpected rainstorm. An engineering plan that is comprehensive should include the sequencing of installation, temporary operation installation, equipment integration and commissioning and not just replacing components.
Making the completed system simpler to operate
Romtec Utilities provides site-specific engineering and supply solutions for wastewater and stormwater pumping applications.
Retrofitting is a process that evaluates structural, mechanical, electrical, and communications components to determine which can be left and which needs to be replaced. The company also offers initial designs and budgetary estimates to help owners evaluate project possibilities.
After installation, startup tests the commissioning process, as well as training for operators are essential to ensure the newly renovated station operates as designed. The successful rehabilitation process should leave operators with a system they are able to maintain and understand.
Make sure you upgrade your computer, not just its age
An older pump station isn’t necessarily a candidate for replacement. Even if the electrical and mechanical components are outdated Some structures may be useful for many years. It is important to know what can be safe and efficiently retained while ensuring the station will meet present and future needs.
When examining operating conditions the structural integrity, hydraulic requirements, and construction constraints together owners can make more informed investment decisions.
The purpose of upgrading an old station isn’t to simply make it work again. It’s to ensure that the new system is well-equipped for the work ahead.
