Engineering would be considerably easier if the water would always arrive at the same pace.

It’s not.

The amount of water that enters a residential water system is subject to change throughout the day. Industrial and commercial facilities can be experiencing operating peaks. The conditions for stormwater can drastically change depending on the weather. The demand for clean water can also increase and decreases based on the use.

It’s not enough just to choose equipment that is able to achieve a specific flow rate when designing an equipment pumping station. Engineers must be aware of the conditions that the system will be subject to.

Be aware of the operating conditions and Not Just the Maximum Capacity

It is evident that maximum flow is important however it is only one aspect of the station’s operation. Imagine that a system for wastewater treatment was created to handle a high flow at peak. In most cases that flow inflows are considerably lower. When this happens when the station is not operating, it must be operating properly.

This leads to questions on wet-well capacity, pump operation, control conditions, head, and how equipment reacts to demand fluctuations.

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 Wastewater Industry has its own daily Timeline

A sewerage lift station serving homes, businesses or municipal infrastructure can be subject to changing influent conditions throughout the duration of its operation.

The system is required to be able to collect water and operate its pumps in line with the plan of control that is set by the station. The dimensions of the structural components, pumping equipment and piping, as well as electrical components and controls all play a a role in this process.

Other considerations specific to the site could influence the design. Romtec Utilities will incorporate any additional systems, like grinders vaults and odor-control devices when needed. The result is a system engineered around the project instead of a generic design applied to every wastewater site.

Stormwater is able to change significantly faster

Stormwater offers a different kind of operating environment. The stormwater stations may be quiet during dry weather, but see a massive inflow of water during a severe weather incident. The station could be an element of a larger flood-control or detention, treatment or drainage strategy, making the stormwater strategy surrounding it an integral part of the design.

In the process of developing these systems, Romtec Utilities considers a variety of aspects, such as the flow rate required and head condition, the dimensions of the system, site requirements, and environmental considerations.

A station that serves a commercial area may, therefore, look completely different from one that is designed for municipal stormwater use.

Head Conditions are Important as well as Flow

Engineers should also be aware of where the water is heading and the resistance they need to overcome. Engineers need to be aware of where the water will go, and what kind of resistance they will have to overcome with the pumping system.

The head condition of the pump can be affected by a variety of variables, including elevation changes and piping configurations, discharge conditions, and various other system characteristics.

The relationship between flow and head is a reason why selecting one based on capacity rating doesn’t suffice. The technology of the pump and station configuration have to suit the requirements of the complete application.

Plan the station in the conditions it is likely to encounter

Romtec Utilities designs and develops custom pumping systems designed to meet the requirements of wastewater treatment, stormwater management, clean water, industrial applications, boosters and much more. The design process begins with preliminary designs plans, budgeting, set-ups systems, supplies for the system, documentation, testing and startup.

The basic engineering principle behind it is clear: the best pumping systems don’t go through their lives under a suitable set of circumstances.

It is also important to consider project-specific hydraulic needs, as well as changing flow, demand, and requirements. It is important to build a station that will deal with this situation.
