It doesn’t take a pump station’s stoppage in functioning to be problematic. It could still transport the water and wastewater daily, yet struggle during high demand, require more frequent maintenance, or rely on controls that are becoming increasingly difficult to support. It may still work however the original layout of the device may not be in line with current needs.

Understanding this distinction is crucial for municipal officials, developers and facility owners when preparing upgrades to infrastructure.

Take a look beyond the equipment that’s Not Working

Retrofitting the wastewater lift station is best done by a thorough assessment of the complete system, not just the pump that is experiencing difficulties. Engineers must evaluate the wetwell as well as mechanical and electrical components. They should also consider discharge piping and the current needs for pumping.

The condition of a well is extremely important. If the wet well’s structure is in good shape, you may be able to replace it with a new equipment while maintaining its existing structure. This could reduce the construction costs as compared to the construction of a new station. However, retaining existing infrastructure only makes sense to support the proposed improvements.

Is the service area changing?

The wastewater station that was constructed many years ago can be used to serve increasing numbers of homes, businesses and industrial activities.

These changes can have an impact on the flow rate and demands on operations. A successful rehabilitation of a lift station is more complicated than simply restoring the original equipment specifications. Engineers need to evaluate the expected and current flows, the total dynamic head of equipment as well as operational reliability and the capacity.

A bigger pump may not be the solution. The new pump must be compatible with existing piping, electrical supply and controls. If you improve one component, it can cause problems with other parts of the system.

The priorities for retrofitting stormwater systems are different

Retrofitting an existing pumping station for stormwater could bring additional concerns due to the fact that runoff is affected by surrounding development and rainfall. A station that is connected to the detention pond could experience different inflow patterns from one receiving water directly via storm drains. Changes in drainage infrastructure like new pavement or expanded parking lots, can affect the timing and amount of water that is available to 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 of these studies can help decide the degree of modernization needed or if the station needs greater reconstruction.

Plan for the Construction Before Interrupting Service

The operation of the station during rehabilitation is often overlooked. It is not possible to stop the wastewater system without having arrangements in place for flow management.

Construction may include temporary bypass pumps or the installation of replacement infrastructure along with an operating station in accordance with the space available and the specific requirements of the project.

The stormwater project also requires a careful planning since the system might require maintenance during rain events that are unexpected. A design plan that is complete should contain the sequencing of installation, temporary operation as well as equipment integration and commissioning as well as replacement components.

The completed System is simpler to operate

Romtec Utilities offers site-specific engineering solutions and supplies for stormwater pumps and wastewater.

Retrofitting is a process that analyzes structural, mechanical, electrical, and communications components to determine which are best left and which needs to be replaced. The company also offers preliminary designs and budgetary estimates for owners to evaluate their project options.

Following installation, tests for startup the system, commissioning it, training for operators as well as operation and maintenance documentation help establish that the newly upgraded station operates in accordance with the specifications of its design. The successful rehabilitation process will leave the operators with a system they are able to manage and comprehend.

Upgrade the System, Not Only Its Age

An older pump station isn’t a guarantee for replacement. It is possible that some structures will remain functional for years, regardless of whether the mechanical or electrical systems require updating. It is crucial to know the things that can be maintained safely and economically while making sure the finished product is compatible with future and current needs.

In assessing the overall operational conditions and structural integrity and the hydraulic requirements and construction constraints, owners are able to make more informed decisions.

The objective isn’t to make an aging station operate again. It’s about ensuring that the new system is able to take on the new work.
