Designing for the Worst Hour, Not the Average Day: Pump Station Capacity Planning

A pumping project may appear straightforward on paper: water is introduced at one point and is required to move to another. However there are a variety of variables that can affect the distance between two locations, including elevation, flow rate solids, pressure storage capacity, and access to maintenance.

Romtec Utilities begin the development of an pumping station by delineating these operating conditions, instead of selecting equipment from catalogues. Preliminary designs and budgetary information are then developed based on what the actual requirements of the project are.

Begin with a simple question: Where are we doing?

The technology is updated immediately.

The flow of wastewater in the domestic system is subject to significant daily variations. The wastewater lift station is necessary when gravity conveyance is not or is not working. Engineers must consider the anticipated inflow and maximum conditions, pumping capacities Wet-well behavior, discharge requirements, as well as how the equipment will be maintained and operated.

Many challenges can be encountered by industrial water. A processing or manufacturing facility might need to move oily, caustic, high-temperature, or high-pressure fluids. Romtec Utilities designs systems for industrial applications ranging from food processing to power generation to data centers, pharmaceutical waste facilities and petroleum and gas facilities.

Rainfall is the cause of a totally different Operating Cycle

Stormwater systems can be inactive for long stretches of time and then suddenly face the possibility of a huge volume in a storm.

A stormwater lift station associated with a detention basin, for example, must work with the site’s larger drainage strategy. The runoff is absorbed by the detention basin. The temporary storage system manages immediately the volume and the pumping system transports the water collected to an approved discharge point.

Romtec Utilities supplied this type of solution for a company park in Norco, California. The pumping equipment was needed to drain the detention basin and discharge it into the stormwater network. The station was been designed to function as component of the drainage infrastructure used for the development, and not as a separate piece equipment.

“Package” Doesn’t Need to mean Off-the-Shelf

The most common misconception is that a pumping system for package pumps is merely a predetermined set of components.

Packaging can be used to organize the primary components of a particular project. The valves and pumps can be selected based on their job needs.

It is especially useful when connecting a new system to an existing infrastructure. In industrial plants and municipal buildings, there’s usually enough space or a perfect environment to install. The equipment may have to be adjusted around the existing pipe systems, structures as well as electrical systems, and operating schedules.

Capacity planning has real consequences.

The cost of undersizing is higher as the facility expands.

Romtec Utilities, a Portland International Airport utility company, created and supplied a sewer interceptor lifting station for the PDX Next project. The new station was designed to double the peak-flow capability of the current system as airport facilities grow.

This example illustrates a key engineering principle: Design specifications shouldn’t be restricted to the capacity of a facility. manage on a typical afternoon. Engineers need to be aware of the impact of demand spikes.

The job isn’t finished until the Equipment arrives

Then, drawings and calculations have to become an operating system. Documentation and coordination of installation are important to long-term success.

In the years following construction, the efficiency of engineered pumping system is measured. The choices made in the initial design are clearly visible when equipment needs maintenance as flows rise or when storms strike.

Romtec Utilities incorporates these options into a pumping solution that is specific to a specific project. This allows us to transform each piece of equipment into an infrastructure designed to withstand the challenges they be confronted with.
