Engineering would be much easier if the water would always arrive at the same rate.
It’s not.
The quantity of wastewater that is pumped into a home’s water system can change throughout the day. Commercial and industrial facilities could have peak operating hours. The conditions for stormwater can drastically change depending on the weather. Demand for clean-water also fluctuates dependent on the use.
As a result, designing pumps isn’t just it’s a matter of finding a flow rate and choosing machines that are able to meet the requirements. Engineers must understand the conditions that the system will be subject to.

Do not just think of the capacity of your equipment, but also operational conditions
The flow that is the highest in importance however, it is just part of the station’s operation. Imagine a wastewater system has been designed to accommodate a high flow. In most cases that flow inflows are considerably lower. During these normal periods, the station must still perform as it should.
This raises questions about wet-well dimensions, pump operation and controls the head, conditions of the pump as well as how the equipment will handle an ever-changing demand.
A properly engineered package pumping system brings these considerations together around the actual requirements of the site instead of treating maximum pump capacity as the entire design objective.
The daily rhythm of wastewater
The conditions for the water that flows through the wastewater liftstation that serves households business, municipal infrastructure or even businesses could change in the course of the operation.
The station should have an appropriate control system that permits the system to activate the pumps and then collect the water. This involves the structural dimensions pumps, valves, pumping gear and pipes, as well as electrical components.
Other considerations specific to the location could influence the design. Romtec Utilities is able to integrate additional equipment like grinder vaults, or odor control equipment, based on the application. This results in a station which is specifically designed to suit the needs of the project, rather than being a standard design that is applicable to all wastewater sites.
Stormwater Can Change Much Faster
Stormwater is a totally different type of operation. A stormwater station is usually quiet in dry weather conditions, but encounter a significant inflow of water in a major weather storm. The station could be a part of a comprehensive flood-control plan or a detention, treatment or drainage plan.
Romtec Utilities evaluates factors including needed flow rates, head conditions, size of the system the site’s requirements, as well as environmental considerations when developing the systems.
A station used for commercial project could, therefore, appear quite different from one engineered for municipal stormwater applications.
Both head conditions and flow are important
The challenge of moving 1,000 gallons not the only problem for engineering. Engineers also have to understand where that water is going and what resistance the pumping system has to overcome.
Variations in elevation, piping design as well as discharge conditions and other system parameters influence the head conditions against which pumps work.
This relationship between flow and head is another reason to select the right pump solely on its rating isn’t enough. The pump technology and station configuration should match the specific hydraulic requirements of the entire application.
The station should be designed to match the actual conditions it will have to endure
Romtec Utilities designs and develops customized pumping systems to address the requirements of wastewater stormwater management as well as industrial applications, boosters, and much more. The process starts with initial design budgeting, planning sets, budgeting, system supplies, documentation, testing and startup.
The principle of engineering that underlies it is simple: true pumping systems don’t go through their entire lives working under one convenient set of conditions.
They also need to take into account project-specific hydraulic needs, as well as changing demand, flow and needs. A successful station has to be engineered for that reality.
