Why Stormwater Retrofits Start With Drainage Conditions

A pump station that is not in good condition doesn’t necessarily need to stop functioning in order to be a problem. Although it could transport stormwater and wastewater on a daily basis it could struggle to keep up with the demand for water at its peak. It could also require frequent maintenance. The equipment works, but its original design may not reflect the current conditions around it.

Recognizing this difference is important for developers, municipalities and facility managers when planning upgrades to infrastructure.

You should look past the equipment that is failing

Retrofitting an wastewater lift station must begin with an assessment of the entire system and not just the pump which is malfunctioning. Engineers need to evaluate the water well, mechanical equipment and electrical components, as well as control systems, discharge pipes, and the current requirements for pumping.

The condition of a wet well is extremely important. It could be possible, if the structure is sound to preserve it and also replace old equipment. It may be cheaper to build an entirely new station than if you decided to preserve the current one. But, keeping existing infrastructure only makes sense as long as it is able to support the planned improvements.

Is the service area changing?

The wastewater plant that was built years ago can now be used to serve more businesses, homes, and industrial facilities.

These modifications can impact the flow rate and operational demands. For lift stations to be successfully rehabilitated, it is not enough to restore the original specifications. Engineers must assess the flow rates, anticipated and current flow rates, total dynamic head capacity of the equipment, and operating reliability.

It’s more than enough to buy a larger pump. The new equipment must be compatible with the current piping system, electrical supply and controls. If not, enhancing one part can create problems elsewhere.

Stormwater retrofits have different priorities

A stormwater pump station retrofit introduces additional considerations because runoff can change dramatically with rainfall and surrounding development. Stations serving a detention basin could differ in their flow patterns from those receiving water through storm drains. The addition of new pavement, larger parking areas or alterations to drainage infrastructure could alter the frequency and amount of runoff reaching the station.

Before recommending a change to an emergency pump station for stormwater engineers should review the drainage area in which they are contributing. They should also examine peak flows expected as well as storage capacity and discharge conditions.

These results can help determine if equipment modernization is enough or if a facility requires greater reconstruction.

Plan for the Construction Before Interrupting Service

The operations of the station in rehabilitation is frequently forgotten. The wastewater system is generally not removed without a plan for continuous flow management.

Construction may include installing temporary bypass pumps or the replacement of infrastructure near the operating station.

The system might be required to be used in an emergency downpour. The engineering plan should include the installation process as well as temporary operations and equipment integration.

Make the Finished System simpler to use

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

The retrofit method decides which electrical, structural mechanical, and communication elements are to be retained and which require replacement. The company gives owners initial plans and estimates for budgets to help them evaluate the options for their project.

After installation, the testing of startup, commissioning, operator training as well as operation and maintenance documentation help establish that the station has been upgraded in accordance with the specifications of its design. A successful rehabilitation project 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’s older may not need to be replaced completely. Some structures may have years of reliable service, even if their mechanical and electrical equipment requires modernization. It is important to know what can be safely and efficiently retained while ensuring the station meets current and future needs.

Owners can make better investment decisions by looking at the operational conditions as well as structural integrity and hydraulic demands together.

It’s not only about making an old station work again. It’s to make sure the upgraded system is prepared for the work ahead.
