Wet Wells, Controls, Pumps, and Valves: How a Lift Station Works as One System

On paper, it might appear simple: the water is pumped into a different location. In practice the distance between those two points can be affected by fluctuating rate of flow, elevation differences and solids, pressure requirements storage capacity, controls electrical equipment, access to maintenance and even site restrictions.

For Romtec Utilities, designing a pump station begins by defining those operating conditions rather than selecting equipment from a standard catalog. Then, preliminary designs and budgetary details can be developed based on what the needs of the project.

Ask yourself: Where do we go?

The technology changes instantly.

The flow of household sewage is subjected to significant variations throughout the day. A wastewater lift facility must move that wastewater reliably in the event that gravity conveyance is not available or insufficient. Engineers must therefore consider the expected flow, the conditions of peak, pumping capacity, wet-well behavior, discharge requirements, as well as how the facility will be operated and maintained.

The difficulties of industrial water differ. The fluids used in manufacturing or processing facility might need to be caustic, oily, or heated with high pressure or temperature. Romtec Utilities creates industrial systems that are used in applications that range from data centers to installations for oil and gas as well as food processing power generation, pharmaceutical waste.

Rainfall has a completely distinct Operating Cycle

Stormwater systems tend to be unoccupied for extended periods and then suddenly confront the possibility of a huge volume in the course of a storm.

For example, a stormwater lift station with a detention basin must be compatible with the overall drainage plan for the location. The runoff enters the detention basin. The temporary storage manages immediately the volume and the pumping system moves the water collected to a discharge point that is approved.

Romtec Utilities supplied this type of solution for a business park located in Norco, California. A pumping system was needed to empty the detention reservoir and discharge it into the stormwater network. The station therefore had to be constructed as part of the development’s drainage infrastructure, rather than being treated as isolated equipment.

Package Does Not Infer “Off the shelf”

Many believe that a package-pumping system is just a predetermined collection of parts.

In the case of engineered infrastructure, packaging could also mean coordinating the key components into one particular project-specific system. Valve and pump components can be determined based on the duty specifications.

That approach becomes especially useful when a new system must connect to existing infrastructure. Municipal and industrial plants facilities usually do not provide a lot of area or pristine installation conditions. Equipment could need to be fitted within existing structures, piping as well as electrical systems and operating schedules.

Capacity planning has real implications

The cost of undersizing increases when the facility grows.

At Portland International Airport, Romtec Utilities designed and supplied the sewer interceptor station to support the PDX Next expansion. The station was built to provide twice the peak-flow capacity of the existing station as the airport’s facilities increased.

This example illustrates a key engineering principal: Design conditions should not be limited to the capacity of a facility. be able to handle during an average afternoon. Engineers also need to understand the impact of the times of peak demand.

The work isn’t done when the equipment arrives

Eventually, drawings and calculations need to be transformed into an operating system. Installation coordination, startup testing documentation, and user understanding are all factors that contribute to the long-term success of.

What happens after the construction of a pumping device determines its quality. The decisions made in the preliminary design are very evident when flows rise, major storms arrive, or maintenance is required.

Romtec Utilities combines these decisions to create a complete pumping solution for a particular project. It assists in turning equipment into infrastructure that is specially designed to meet the specific conditions for which it is employed.
