A pump station that is old shouldn’t be forced to cease functioning in order to become a source of concern. It may still move water or wastewater every day however, it struggles during periods of high demand, need frequent maintenance or depend on controls that are getting harder to support. While the equipment is operating but its original design might no longer be appropriate for today’s conditions.

For municipal governments, developers and facility owners, being aware the differences is a crucial part of planning infrastructure improvements.
The equipment that fails isn’t the sole issue
A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers should assess the wetwell and mechanical equipment as well as electrical components, control systems, drainage pipes and current requirements for pumping and control systems.
The condition of the well is of particular importance. If its structure remains sound, it may be possible to retain it as a replacement for outdated equipment. This could reduce the construction costs compared with building an entirely new station. It is crucial to maintain existing infrastructure if the enhancements can be made.
Is the service area changing?
An old wastewater treatment plant may serve additional houses, industrial buildings, or commercial properties.
These modifications can impact flows and operating demands. In order for lift stations to be successful in rehabilitation, it’s not enough to return to original specifications. Engineers should assess current and anticipated flow rates as well as the equipment’s capacity and performance.
It’s not enough just to purchase a bigger pump. New equipment should work with the existing system of piping and wet wells, electrical supply, controls, etc. If one component is upgraded the result could be problems with the other components.
Stormwater Retrofits Have Different Priorities
Retrofitting an existing pumping station for stormwater could result in additional challenges due to the fact that runoff is influenced by surrounding development and rainfall. A station serving an detention pond may have different patterns of inflow from those that receives water through storm drains. The addition of new pavement, larger parking areas, or altered drainage infrastructure could also alter the quantity and frequency of runoff reaching the station.
Before recommending a change to an existing stormwater pump station, engineers should examine the drainage area of the pump station. They should also review the expected peak flows, storage capacity and discharge conditions.
These findings can help determine whether the modernization of equipment is sufficient or whether the station requires more extensive reconstruction.
Plan the Construction Before Interrupting Service
The operations of the station in rehabilitation is frequently neglected. Systems for managing wastewater generally can’t be taken offline without arrangements for ongoing flow control.
Construction may include installing temporary bypass pumps or replacing infrastructure adjacent to the station operating.
The system could be required for an unexpected rainstorm. The engineering plan must include the installation sequence in addition to temporary operations and equipment integration.
Making the completed system simpler to operate
Romtec Utilities offers site-specific engineering solutions and supplies for stormwater and wastewater pumps.
The retrofit method determines which electrical, structural, mechanical and communication components should be kept and which ones need replacement. The company gives owners preliminaries designs and budget estimates to help them evaluate project options.
After installation, the testing of startup, commissioning, operator training as well as operation and maintenance documentation will ensure that the station has been upgraded in accordance with its specifications. A successful rehabilitation effort should leave operators with a station they can manage and comprehend.
Upgrade your system, not just your system’s age
A pump station that is older may not need to be replaced completely. It is possible that some structures will continue to be functional for many years, even if mechanical and electrical systems require modernization. It is crucial to know what can be kept safely and economically, while ensuring that the station’s finished product is compatible with future and current demands.
Owners can make better investment decisions by reviewing the conditions of operation along with structural integrity, hydraulic and needs together.
The purpose in upgrading an older station isn’t to just make it function again. The aim is to make sure that the upgraded system can cope with the new demands.
