A pump station that’s old doesn’t need to stop working in order for it become a concern. It can still transfer water or wastewater every day and yet be unable to cope with the peak times, require frequent maintenance or rely on control systems that are becoming increasingly difficult to maintain. The equipment functions, however its original design might not accurately reflect the environment surrounding it.

Planning for infrastructure improvements is essential for city officials, developers, and the operators of facilities.

The Equipment that is failing isn’t the only problem

A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers should examine the wetwell and mechanical equipment and electrical components as well as controls, drainage piping and current requirements for pumping and control systems.

The state of the wet well is particularly important. It might be possible when the structure is in good condition in its current condition, to maintain it and upgrade the equipment. Costs for construction could be reduced when compared to the construction of a new station. However, retaining existing infrastructure only makes sense in the context of enhancements that are planned.

Has the Service Area Modified?

A wastewater station designed decades ago could now be serving more homes, commercial buildings or industrial activities.

These modifications could affect the rate of flow and operational needs. Rehabilitating a lift station successfully is more complicated than simply restoring the original specifications for the equipment. Engineers should evaluate the flow rates and expected flow rates as well as the equipment’s capacity and performance.

The solution is not always a bigger pump. The new equipment should be compatible with the current piping system, electrical supply and controls. If you make improvements to one part, it can cause problems in other areas.

Priorities for stormwater retrofits are different

Retrofitting an existing pumping station for stormwater could result in additional challenges because runoff is influenced by the surrounding development and rain. The inflow pattern of an area that has an area for detention could differ from when it is receiving water directly through the storm drain. The amount of runoff that reaches the station could be affected by new pavement as well as increased parking or a change in drainage infrastructure.

Before recommending a stormwater station upgrade, engineers should look at the contributing drainage area the anticipated peak flows, storage capacity, discharge conditions as well as the performance of the existing pump.

These findings can help determine whether the modernization of equipment is sufficient or if the station requires larger reconstruction.

Plan your construction before you interrupt service

The operation of the station during rehabilitation is frequently neglected. It is not possible to remove wastewater systems from operation without making arrangements for flow management.

Depending on the available space and project needs the construction could involve temporary bypass pumping or installing replacement infrastructure alongside the operating station.

The system could be necessary to be used in an emergency downpour. A design plan that is comprehensive must include installation sequencing, temporary operation, equipment integration and commissioning and not just replacing components.

Making the finished system easier to use

Romtec Utilities provides site-specific engineering and supply solutions for wastewater and stormwater pumping needs.

The retrofit method will determine which electrical, structural mechanical, communication and structural components should be kept and which components require replacement. The company also offers preliminary designs and budgetary estimates to help owners analyze project possibilities.

After installation, startup tests as well as operator training are essential to ensure the newly upgraded station is functioning according to the specifications. A successful rehabilitation project will provide the operator with a system that they can manage and comprehend.

Upgrade Your System and Not Just its Age

A pump station that’s older isn’t a guarantee to be completely replaced. It’s possible that some structures will continue to be functional for years, even if mechanical and electrical systems require modernization. It is essential to identify the items that can be preserved safely and cost-effectively, while ensuring that the station’s finished product meets current and future requirements.

In assessing the overall working conditions and structural integrity along with the requirements for hydraulics and construction constraints, owners can to make better-informed decisions.

It’s not just about trying to make a stale station operate again. It’s about making sure that the new system is well-equipped to handle the challenges ahead.
