It’s not necessary for a pump station to cease working for it to become an issue. It may still move water or wastewater every day and yet be unable to cope with the peak times, require frequent maintenance or depend on controls that are getting harder to support. The equipment is functional, but its design may no longer reflect the conditions surrounding it.
The importance of recognizing this difference is for developers, municipalities and facility managers when planning upgrades to infrastructure.

See beyond the equipment Broken
The retrofit of a water liftstation must begin by evaluating the entire system and not just the pump. Engineers must assess the wetwell as well as mechanical and electrical parts. They should also consider discharge pipes as well as the needs of current pumping.
The state of the well is particularly important. If the structure of your wet well is intact, you may be able to replace it with new equipment while keeping the existing structure. This can reduce construction requirements in comparison to building a new station. It is important to keep existing infrastructure if the improvements can be made.
The service area has changed.
The wastewater plant that was constructed years ago can be used to serve many more households, businesses as well as industrial processes.
These changes can have an impact on flows and operational demands. Rehabilitating a lift station is more than just restoring the original specifications for the equipment. Engineers must evaluate the current and anticipated flows, total dynamic head equipment capacity, operating reliability.
It’s more than enough to buy a larger pump. New equipment should work with the existing piping system and wet wells, electrical supply, controls and more. If not, enhancing one part can cause issues elsewhere.
Stormwater retrofits may have different priorities
A stormwater pump station retrofit adds more considerations as runoff is subject to change with rainfall and surrounding development. Stations that are part of a detention basin may differ in their flow patterns from those that receive water via storm drains. The changes in drainage infrastructure like new pavement or expanded parking lots, can affect the frequency and quantity of water that’s 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 results will help you determine if the station requires to be rebuilt or if the modernization of equipment is enough.
Plan Construction Before Interrupting Service
The operations of the station in rehabilitation is often overlooked. It is not possible to close down the wastewater systems without making arrangements for flow management.
Based on the space available and project needs the construction could involve temporary bypass pumps or the installation of new infrastructure in conjunction with the operating station.
It is also essential to prepare for stormwater projects as the system may be needed in unexpected rainstorms. The engineering plan must contain the installation process, temporary operations and equipment integration.
Enhance the finished System easier to operate
Romtec Utilities provides site-specific engineering and supply solutions for wastewater and stormwater pumping requirements.
Retrofitting analyzes structural, mechanical, electric, and communications components to determine which components can be kept and which should be replaced. The company gives owners preliminary designs, budget estimates as well as project options.
After installation, the tests of startup the commissioning process, as well as training for operators is essential to make sure that the new station is operating in accordance with its specifications. Rehabilitation projects that are successful should provide operators with an easy-to-maintain system.
Improve the System, Not Only Its Age
An older pumping station doesn’t mean it’s a perfect candidate for replacement. Some structures may have years of service left, even when their electrical and mechanical equipment requires modernization. The most important thing to consider is what is safe and economically while ensuring that the constructed station meets current and future demands.
In assessing the overall working conditions and structural integrity as well as the hydraulic requirements and construction constraints, owners are able to make better informed decisions.
It’s not about just making the old station operational. It’s about ensuring that the new system is able to take on the new work.
