On paper, it might seem straightforward: water is pumped to a different location. In actuality the distance between those two points can involve changes in flows, elevation changes as well as solids, pressure requirements storage capacity,, electrical equipment, access to maintenance and restrictions on the site.
For Romtec Utilities, the design of a pump station starts with delineating the operational conditions instead of selecting the equipment from a catalog. Preliminary designs and budgetary information are then developed based on what the project actually requires.

Let’s start with one question How are We Moving?
The solution immediately alters the process of engineering.
Domestic sewage may contain solids, and can experience a variety of variations in flow. The wastewater lift station will be required in the event that gravity conveyance fails or will not function. Engineers should take into account the following aspects: expected flow and peak conditions, pumping capability, wet well behavior discharge requirements, and how the equipment is maintained and operated.
Diverse challenges arise from industrial water. Fluids that are caustic, oily or have high temperatures or pressures might be needed by a processing or manufacturing facility. Romtec Utilities designs industrial systems to support a variety of applications, from power generation and food processing to data centers pharmaceutical waste, oil and gas facilities.
Rainfall is the cause of a totally different Operating Cycle
Stormwater systems can be inactive for prolonged periods, only to suddenly have to deal with large volumes in the course of a major storm.
A stormwater liftstation that is connected to an existing detention basin should, for instance, work alongside the overall drainage plan of the site. When the runoff flows into the detention basin, where the temporary storage system manages immediately the volume and the pumping system moves the collected water to an authorized discharge point.
Romtec Utilities supplied this type of solution for a company park in Norco, California. A pumping system was needed to empty the detention basin and then discharge it into the stormwater network. This station had to be engineered as part of the drainage infrastructure, not as isolated equipment.
“Package” Doesn’t Signify “Off the shelf”
A common misconception is that a package pumping system is simply a predetermined collection of components.
For engineering infrastructure, packing could mean coordinating all the major pieces into one project-specific system. The valves and pumps can be selected according to their duty requirements.
This is especially beneficial when the new system needs to be connected with an existing infrastructure. Industrial plants and existing municipal facilities may not offer a large amount of space for installation, or even in good condition. Equipment may have to be placed around existing piping, structures electric systems, as well as operational schedules.
The Real Costs of Capacity Planning
It is especially costly when facilities grow.
Romtec Utilities, a Portland International Airport utility company, developed and built a sewer interceptor lifting station to the PDX Next project. The new station was required be constructed to provide twice the capacity at peak flow as the airport expanded.
This example illustrates a key engineering principle: Design specifications should not be limited by the limitations of what a building can be able to handle during the typical afternoon. Engineers need to be aware of the impact of demand spikes.
The job is not finished until the equipment arrives.
Drawings and calculations will eventually become an operating system. Installation coordination, startup testing documentation, and operator understanding all contribute to the long-term success of.
In the years following construction, the effectiveness of an engineered pumping system is assessed. The decisions made in the beginning of the design are obvious when the pump needs to be maintained and flows increase, or the weather strikes.
For Romtec Utilities, integrating these decision-making processes into a total project-specific pumping system helps transform each piece of equipment into infrastructure that is designed to meet the demands they’ll be confronted with.
