Planning a Lift Station That Operators Can Actually Maintain

A pumping project may appear straightforward on paper: water arrives at a specific location and has to travel to another. In real life the distance between those two points may be subject to changing rate of flow, elevation differences in solids, pressure demands, storage capacity, control and electrical equipment, access to maintenance and restrictions at the site.

Romtec Utilities begins the design of the pumping station with defining these operating conditions, rather than selecting the equipment from catalogues. Initial designs and budgetary details are then developed based on what the project actually requires.

Consider: Where do we go?

The engineering is changed immediately.

Domestic sewage is often contaminated with solids and may experience significant fluctuations in the daily flow. The wastewater lift station is needed in the event that gravity conveyance fails or will not function. Engineers must consider the anticipated inflow and maximum conditions, pumping capacities as well as wet-well behaviour and discharge requirements, as well as how the equipment will be maintained and operated.

Many challenges can be encountered by industrial water. Fluids that are caustic, oily or that have high temperatures or pressures may be needed by a processing or manufacturing facility. Romtec Utilities designs systems for industrial applications ranging from food processing and power generation, data centers, pharmaceutical waste and gasoline and oil facilities.

Rainfall is the cause of a totally different Operating Cycle

Stormwater systems are often inactive for prolonged periods of time but then suddenly they face an enormous volume of water during an event.

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

Romtec Utilities provided this solution for the creation of an Norco business park in California. The development needed the construction of a pumping station that would empty an existing detention system into the public stormwater drainage network. The station was planned to work as a component of the drainage system for a particular development rather than an individual part of the equipment.

“Package Does Not Signify “Off the shelf”

A common misconception is that a package pumping system is simply a predetermined collection of components.

In the case of engineered infrastructure packaging can mean that all major components are integrated into one system. Valve and pump components can be chosen based on their use needs.

This approach is especially helpful for systems that need to be connected to an existing infrastructure. In municipal and industrial structures, there’s not enough space or a complete clean environment for the installation. It could be necessary to alter equipment to accommodate existing structures, pipes electrical systems, schedules and schedules.

Capacity Planning Has Real Consequences

Undersizing becomes particularly costly when facilities grow.

In Portland International Airport, Romtec Utilities created and installed an sewer interceptor lift station for the PDX Next expansion. The new station was built to double the peak-flow capacity of the previous system, as the airport facilities expanded.

This illustrates an important aspect of engineering: construction conditions must not just represent what an installation does during an average afternoon. Engineers need to be aware of what happens when demand peaks.

The work isn’t complete until the Equipment arrives

Then, drawings and calculations have to become an operating system. Coordination of installation, starting testing documentation, and operator knowledge all affect long-term performance.

A properly engineered pumping system is ultimately determined by what happens in the years following the construction. The decisions made during initial design are clearly visible when the pump needs to be maintained and flows increase, or an event occurs.

Romtec Utilities integrates these decisions into a pumping system that is tailored to a project. This can help transform individual equipment into an infrastructure that is designed for the conditions they will have to face.
