An old pump station doesn’t have to stop working before it’s a problem. It might still be able to move the water and wastewater daily and yet be unable to cope with the peak times, require frequent maintenance, or rely on controls that are becoming difficult to support. It could still be functional however, the original layout of the device may not reflect current conditions.

Planning for infrastructure improvements is essential for city officials, developers and the operators of facilities.
You need 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 must assess the wet well, the mechanical equipment and electrical components, as well as control systems, discharge pipes, and the current requirements for pumping.
It is essential to observe the state of your wet well. It is possible, in the event that the structure is sturdy that it be kept and replace outdated equipment. Costs for construction could be reduced when compared to the construction of a new station. It is essential to preserve existing infrastructure if the improvements can be made.
Has the service area changed?
The wastewater station that was constructed many years ago can be used to supply more homes, businesses, and industrial facilities.
The changes could impact the rate of flow and operational requirements. The rehabilitation of lift stations requires more than just the restoration of original specifications for the equipment. Engineers must evaluate flow rates and expected flows, as well as the equipment’s capacity and performance.
A bigger pump isn’t always the answer. New equipment should work with the existing piping system as well as wet wells, electrical supply, controls, and more. When one part is improved, this can lead to problems with other components.
Stormwater Retrofits have Different Priorities
Retrofitting an existing pumping station for stormwater could result in additional challenges due to the fact that the runoff can be affected by nearby development and rainfall. The pattern of inflow at an area that has a detention area may be different from if it receives water directly from the storm drain. New pavement, expanded parking areas or alterations to drainage infrastructure could alter the amount and timing of runoff that reaches the station.
Before recommending a stormwater pump upgrade, engineers should review the contributing drainage area, expected peak flows storage capacity, discharge conditions, as well as the performance of the existing pump.
These results help determine if modernization of the equipment will suffice or if the station is in need of greater reconstruction.
Plan Construction Before Interrupting Service
What the station’s capabilities will be in rehabilitation is a subject that is frequently left unanswered. The wastewater system is generally not removed without a plan for continued flow management.
Construction may include temporary bypass pumps or installation of replacement infrastructure along with an operating station dependent on the available space and the project requirements.
It is important to be prepared for stormwater-related projects because the system could be required during unexpected rainstorms. A complete engineering plan should include installation sequencing, temporary operations, the integration of equipment, and commissioning not just the replacement of the components.
The final System is easier to Operate
Romtec Utilities offers site-specific engineering solutions and equipment for stormwater pumps and wastewater.
The company’s retrofit strategy identifies the mechanical, structural, electrical, and communication elements should be left in place, and which will require replacement. The company gives owners initial designs and budget estimates to assist them in evaluating alternatives for their projects.
After installation, startup tests the commissioning process, as well as training for operators are essential to ensure the new station is operating as designed. Operators need to be able manage and comprehend the system following the successful rehabilitation.
Make sure you upgrade your computer, not only the system that is old
An older pump station isn’t always a good candidate for complete replacement. Even if their electrical and mechanical components are outdated certain structures could be of use for a number of years. It is crucial to determine what can be safely and economically retained, while ensuring that the station meets current as well as future needs.
By examining operating conditions, structural strength, hydraulic requirements and construction restrictions together, owners can make more informed investment choices.
It’s not only about making an old station work again. To make sure that the station is ready for future work it’s essential to improve the station.
