A pump station that is old shouldn’t be forced to cease functioning in order to become a source of concern. While it can move wastewater and stormwater daily, the pump station might struggle to meet peak demand. It might also require regular maintenance. While the equipment remains operating, its original design might not be adequate for today’s conditions.

For municipalities, developers, and facility owners, being aware the difference is an essential element of planning for infrastructure improvements.
It is important to look beyond the equipment not working properly.
A wastewater lift station retrofit should begin with an assessment of the complete system, not simply the pump experiencing problems. Engineers must evaluate the wet well, mechanical equipment, electrical components, controls, discharge piping as well as the current needs for pumping.
It is important to observe the condition of the wet well. If the wet well’s structure is in good shape, you may be able to replace it with a new equipment while keeping its existing structure. This will reduce the amount of construction needed in comparison to building a new station. It is essential to preserve the existing infrastructure even if enhancements can be made.
Has the Service Area Modified?
A wastewater station designed in the past could be used to serve more commercial and residential buildings, homes, or industrial operations.
These modifications could alter the flow rate and demands on operations. Successful lift station rehabilitation therefore is more complicated than simply restoring the original specifications of the equipment. Engineers must evaluate the flow of current and anticipated flows, the total dynamic head of equipment as well as operational reliability and the capacity.
It’s not enough to simply buy a bigger pump. The new equipment has to work with existing pipes, wet well, electric supply and control. When one part is upgraded, it can cause problems with other components.
Stormwater retrofits have different priorities
Retrofitting an existing stormwater pumping station may bring additional issues due to the fact that runoff is influenced by the surrounding development and rainfall. The pattern of inflow at an area that has the detention area could differ from when it gets water directly from the storm drain. The amount of runoff that reaches the station is affected by new pavements as well as increased parking or the alteration of drainage infrastructure.
Before recommending a stormwater station upgrade, engineers should examine the contributing drainage area and the expected peak flows, storage capacity, discharge conditions and the current pump performance.
These findings can help determine whether equipment modernization will be sufficient or if the station is in need of greater reconstruction.
Design your project before you disrupt service
The operation of the station during rehabilitation is often ignored. The general rule is that wastewater systems can’t be removed without a proper plan to control flow.
The construction process may involve the installation of temporary bypass pumps or relocating infrastructure that is adjacent to the operating station.
It is important to think ahead about stormwater-related projects because the system might be needed during unexpected rainstorms. The engineering plan must contain the installation process in addition to temporary operations and equipment integration.
The Finished System is much easier to use
Romtec Utilities is a provider of site-specific engineering, supply and solutions for Stormwater and Wastewater Pumping Applications.
The retrofit strategy decides which electrical, structural mechanical, communication and structural components should be kept and which ones need replacement. The company provides owners with preliminary designs, estimates of budgets as well as project options.
Following installation, startup testing the system, commissioning it, training for operators and operation and maintenance documents help ensure that the newly upgraded station operates in accordance with its specifications. The successful rehabilitation process will leave the operators with a station they can maintain and understand.
Upgrade the System, Not Only Its Age
A pump station that’s older isn’t necessarily a candidate for complete replacement. Even if their electrical or mechanical equipment is old, some structures can still be of use for a number of years. It is important to know what is safe and effectively preserved while ensuring the station will meet present and future needs.
Owners can make better investment decisions by looking at the operational conditions including structural integrity, structural integrity and hydraulic requirements together.
It’s not about just making the old station operational. It’s to ensure that the upgraded system is prepared for the task ahead.
