An aging pump station isn’t required to shut down before it becomes a problem. While it can transport stormwater and wastewater on a daily basis it could struggle to meet the demand for water at its peak. It could also require frequent maintenance. The equipment functions, however its design may no longer reflect the conditions surrounding it.
It is vital to recognize this distinction for developers, municipalities and facility managers in planning improvements to infrastructure.

Look Beyond the Equipment That’s Not Working
A retrofit of a wastewater pump station must begin with an evaluation of the whole system, not simply the pump experiencing issues. Engineers need to evaluate the wet well, mechanical components and electrical components, as well as control systems, discharge pipes, and current pumping requirements.
The state of the well is of particular importance. If its structure is in good condition and in good condition, it could be feasible to keep it in place as a replacement for outdated equipment. Costs of construction can be reduced in comparison to building a new station. But, keeping the existing infrastructure is only a good idea as long as it is able to support the proposed improvements.
Has the service area changed?
A wastewater plant that was built many years ago can now provide other commercial or residential properties, homes or industrial facilities.
These modifications can impact the operating requirements and flow rates. Successful lift station rehabilitation therefore requires more than restoring the original equipment specifications. Engineers should evaluate their current and future flows, head dynamics capacity of the equipment, and operational reliability.
The solution is not always one that is bigger. New equipment needs to be compatible with the existing piping and wet well, as well as the electric supply and controls. In the event that one component is improved, it can cause issues elsewhere.
Stormwater Retrofits Have Different Priorities
Retrofitting a stormwater pump station introduces additional considerations because runoff is subject to change depending on the amount of rainfall and development surrounding. A station that serves an detention pond may have different flow patterns than one receiving water directly through storm drains. The amount of runoff that gets to the station can be affected by new pavement in addition to parking space, or the alteration of drainage infrastructure.
Before recommending an upgrade to a stormwater pump station, engineers should examine the drainage area in which they are contributing. They should also review the anticipated peak flows, storage capacity and discharge conditions.
These findings can help determine if equipment modernization is enough or if a station is in need of greater reconstruction.
Design the Construction Before Interrupting Service
One frequently overlooked issue is how the station will be operating during rehabilitation. The wastewater system is generally not taken offline without arrangements to ensure that flow control is maintained.
Construction can involve installing temporary bypass pumps, or even replacing the infrastructure surrounding the operating station.
The stormwater project also requires a careful planning since the system might be needed during unexpected rainfall. The engineering plan must contain the sequence of installation as well as temporary operations and equipment integration.
The completed System is much easier to use
Romtec Utilities is a provider of engineering services for sites supply and solutions for Stormwater and Wastewater Pumping Applications.
Retrofitting analyzes structural, mechanical, electric, and communications components to determine which can be left and which needs to be replaced. The company gives owners initial designs and budget estimates to help them evaluate project options.
After installation, the tests of startup as well as operator training are important to ensure that the upgraded station is performing in accordance with its specifications. A successful rehabilitation project will leave the operators with a system they can maintain and understand.
Improve the System, Not Just Its Age
It’s not necessary to replace an older pump station. Even if their electrical or mechanical equipment is old Some structures may be useful for many years. It is essential to identify the items that can be preserved safely and economically, while ensuring that the station’s finished product is in line with current and future needs.
Owners are able to make better investment choices by examining the conditions of operation including structural integrity, structural integrity and hydraulic needs together.
The aim in upgrading an older station is not to make it functional again. It’s about ensuring that the upgraded system can handle the upcoming work.
