Planning a Lift Station That Operators Can Actually Maintain

On paper, it could seem simple: water is pumped into a different location. In reality there are a myriad of factors that affect the distance between two locations, including: elevation and flow rate, solids, pressure, storage capacity, and access to maintenance.

Romtec Utilities starts the design of an pumping station by delineating the operating conditions rather than choosing equipment from catalogues. The project’s requirements can be used to create preliminary designs and budgetary data.

Begin with a single question What’s the Next Step?

The solution immediately alters the engineering.

There can be significant fluctuations in the rate of flow of domestic sewage. A wastewater lift station must move that wastewater reliably when gravity conveyance is unavailable or insufficient. Engineers must consider the expected inflow and high-pressure conditions, pumping capacities Wet-well behavior, discharge requirements, as well as the manner in which the equipment is maintained and operated.

The water challenges faced by industrial facilities are various. Processing or manufacturing facilities may require moving high-temperature, caustic, oily, or high-pressure fluids. Romtec Utilities designs industrial systems that can be used for everything from food processing and power generation to data centers as well as pharmaceutical waste and oil and gas facilities.

Rainfall may create a completely different operating system

Stormwater systems tend to be unoccupied for long stretches of time and then suddenly confront an enormous volume of water during a storm.

A stormwater liftstation connected to an detention basin must work, for example, in conjunction with the larger drainage plan of the site. The basin is filled with runoff and temporary storage manages the volume immediately, and the pumping system moves the water collected towards an approved discharge point.

Romtec Utilities supplied this type of service for a commercial park development in Norco, California. The project required a pumping device to discharge a basin of detention into the stormwater system of the public. The station was planned to be part of a drainage system in a development rather than as an independent piece of equipment.

“Package Doesn’t Mean “Off the shelf”

It is a common misconception that a pumping mechanism for packages is just a collection of predetermined parts.

For infrastructure that is engineered, packaging could also mean coordinating the major pieces into one project-specific system. Controls, pumps and meters and components for structural construction and equipment, can be chosen in accordance with the requirements of the project.

This strategy is especially useful when the system is required to be connected to an existing infrastructure. Industrial plants and existing municipal facilities do not always offer a large amount of space for installation, or even well-maintained conditions. It is possible to adjust equipment around existing structures, piping, electrical systems and schedules.

Capacity planning has real implications

In particular, undersizing can be costly as facilities grow.

Romtec Utilities, a Portland International Airport utility company, developed and built the sewer interceptor station for the PDX Next project. The new station was required to be designed to have twice the capacity at peak flow as the airport expanded.

It demonstrates an important engineering principle: design conditions should not reflect only the way a facility can handle on a normal afternoon. Engineers also need to understand the impact of peak demand.

The job isn’t finished until the Equipment is delivered

In the end, drawings and calculations will eventually become a functioning system. Installation coordination, startup testing documentation, and user understanding are all factors that contribute to the long-term success of.

A properly designed pumping device is largely determined by the events that occur after construction. The choices made in the initial design are clearly visible when the equipment requires maintenance, flows increase or a storm hits.

Romtec Utilities blends these choices in order to develop a complete pumps solution for a specific project. It can help turn equipment into infrastructure specifically designed for the conditions for which it is utilized.
