An old pump station isn’t required to shut down before it becomes a problem. It might still be able to move wastewater or stormwater every day but struggle to meet periods of high demand, need frequent maintenance or rely on controls which are becoming more difficult to support. It could still function but the initial design of the equipment might not be a reflection of the current situation.

For municipalities, developers, and facility managers, understanding the distinction is an important aspect of preparing infrastructure improvements.

Take a look beyond the equipment that’s Failing

The retrofit of a water liftstation should begin by looking at the whole system, not just the pump. Engineers should assess the wetwell and mechanical equipment and electrical components as well as drainage pipes, controls, current pumping requirements, and control systems.

The state of the wet well is particularly important. If the wet well’s structure is still sound then you might be able to change it out with a new equipment while keeping the existing structure. This may reduce the need for construction as compared to the construction of a new station. However, the idea of preserving the existing infrastructure is only a good idea when it can support the enhancements that are planned.

Did the area of service change?

The wastewater station that was constructed many years ago can be used to supply more businesses, homes, as well as industrial processes.

These modifications could affect the operating requirements and flow rates. Successful lift station rehabilitation therefore requires more than restoring the original equipment specifications. Engineers should assess their current and future flow rates, total dynamic head, equipment capacity, and operational reliability.

It’s not enough to simply buy a bigger pump. The new equipment should work with existing pipes and wet well, as well as the electric supply and controls. If you modify one of the components, it can cause problems with other parts of the system.

Stormwater Retrofits Have Different Priorities

Retrofitting a station to pump stormwater is not without its own challenges, as the runoff patterns are affected by rainfall and nearby development. Stations serving detention basins may have different inflow patterns than those that receive water via storm drains. The changes in drainage infrastructure like new pavement or larger parking lots, may affect the frequency and quantity of water that can be allowed to flow into the station.

Before recommending a new stormwater system, engineers need to look over the drainage areas and peak flows anticipated and the storage capacity available along with discharge conditions and pump performance.

The results will help you determine if the station requires to be renovated or whether modernizing the equipment is enough.

Design the Construction Before Interrupting Service

The way the station functions when it is being renovated is a matter that is often overlooked. It is impossible to remove wastewater systems from operation without making arrangements for the flow control.

Construction can involve installing temporary bypass pumps or replacing infrastructure adjacent to the station operating.

The stormwater project also requires careful scheduling due to the fact that the system could be needed during unexpected rainfall. The engineering plan should include the installation process, temporary operations and equipment integration.

Making the system more user-friendly to use

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

The retrofit strategy decides which electrical, structural mechanical, communication and structural components should be kept and which ones need replacement. The company gives owners preliminary designs, budget estimates and options for projects.

Following installation, tests for startup testing, operator training and commissioning are important to ensure that the newly renovated station operates according to the specifications. Operators should be able keep the station operating and comprehend it following the successful rehabilitation.

Upgrade Your System and Not Limit Its Upgrades to the Age

An older pumping station isn’t necessarily a candidate to be completely replaced. Some structures may have decades of useful service remaining, even when their mechanical and electrical equipment needs modernization. The most important thing to consider is what is safe and economically, while also ensuring that the finished station meets present as well as future needs.

Owners can make better investment decisions by reviewing the operating conditions as well as structural integrity and hydraulic requirements in conjunction.

It’s more than just getting an old station work again. To make sure the station is ready for future work It is crucial to modernize the station.
