Post: A Lift Station Built for Yesterday’s Development

It’s not hard for the pump station to stop functioning for it to become problematic. The pump station might be able to transport water or wastewater throughout the day but it struggles when the demand is high. It may require regular maintenance or rely on controls which are difficult to maintain. The equipment is functional, but its design may not reflect the current conditions around it.

Developers, municipalities, and facility operators, acknowledging that difference is an important aspect of preparing infrastructure improvements.

The equipment that fails is Not the Only Problem

A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers need to evaluate the water well, mechanical components as well as electrical components, controls, discharge pipe, and current pumping requirements.

The condition of the well is of particular importance. If the structure is sound it is possible to preserve it when replacing equipment that is no longer in use. Construction costs can be reduced in comparison to building a new station. Retaining existing infrastructure only makes sense as long as it helps the changes being planned.

Have the boundaries of the Service Area Modified?

The wastewater facility that was built years ago can now be used to provide services to more homes, businesses, as well as industrial processes.

These changes can alter the flow rate and demands on operations. A successful rehabilitation of a lift station will require more than just restoring original specifications of the equipment. Engineers must assess the future and planned flows as well as the equipment’s capacity and reliability.

It’s more than enough to buy a bigger pump. New equipment needs to work with the existing piping system as well as wet wells, electrical supply, controls etc. If not, enhancing one part can create problems elsewhere.

The priorities for retrofitting stormwater systems are different

Retrofitting a pump station for stormwater has additional concerns, since runoff patterns may be affected by rain and nearby development. The flow pattern at an area that has the detention area could be different than if it gets water directly from the storm drain. The quantity of runoff reaching the station is affected by new pavements, increased parking, or a change in drainage infrastructure.

Before recommending a proposed stormwater station upgrade, engineers should look at the drainage area of the station the anticipated peak flows, storage capacity, discharge conditions, and current pump performance.

These findings will help to determine the degree of modernization needed or if the station needs greater reconstruction.

You should plan your construction in advance of when you disrupt service

The operation of the station during rehabilitation is often ignored. It is impossible to stop the wastewater system without having arrangements in place for flow control.

Depending on the available space and project requirements Construction may require temporary bypass pumping or replacement infrastructure alongside the operating station.

The stormwater project also requires a careful planning due to the fact that the system could require maintenance during rain events that are unexpected. A plan for engineering that is comprehensive must include installation sequencing, temporary operation installation, equipment integration and commissioning not only replacement parts.

Making the completed system simpler to operate

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

Retrofitting is a method that evaluates structural, mechanical, electrical, and communications components to determine which components can be kept and which should be replaced. The company also provides preliminary plans and estimates for budgets 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 as designed. The successful rehabilitation process will leave the operators with a system they are able to maintain and understand.

Improve the System, Not Only Its Age

A pump station that is older might not need to be replaced completely. Even if electrical and mechanical components are outdated certain structures could be useful for many years. The key is to determine the things that can be kept safely and economically while ensuring that the constructed station meets current and future demands.

Owners are able to make better investment choices by looking at the operating conditions as well as structural integrity and hydraulic needs together.

The purpose in upgrading an older station is not just to fix it again. The goal is to ensure that the new system is able to handle the upcoming work.
