Engineering would be a lot easier if the water would always arrive at the same speed.

It isn’t.

Wastewater entering a residential system could vary over the course of the day. Industrial and commercial buildings can have operating peaks. Stormwater flow can be affected by weather conditions. The demand for clean water also varies in relation to its use.

To design an efficient pumping station, it’s not a simple matter of selecting the equipment that can meet a specific flow. Engineers need to be aware of the environment that the equipment will be exposed to.

Be aware of the operating conditions and not just the Maximum Capacity

The greatest flow is vital however, it is just one element of the station’s operation. Imagine that a wastewater treatment system was designed to handle a high maximum flow. The majority of the time the flow that enters it could be significantly lower. During normal operating hours the station must be functional.

This brings up questions about wet-well capacity, pump operation, head conditions, controls, and how the equipment performs to demand fluctuations.

The design of an engineered package pumps system considers the requirements of the particular site instead of focusing solely on the maximum capacity of the pump.

Wastewater Has Its Own Daily Timeline

A wastewater lift station serving homes, businesses, or municipal infrastructure may experience changing influent conditions throughout its operating cycle.

The station must have an effective control plan that permits the system to activate the pumps and then collect the water. This involves design and dimensions of the structure, pumping gear, valves and pipes, as well as electrical components.

The design could also incorporate particular considerations for the location. Romtec Utilities is able to include auxiliary equipment, like grinder vaults, or odor control equipment, based on the application. This creates a station which is specifically designed to suit the project, rather than being a generic design which can be applied to all wastewater sources.

Stormwater Changes Much More Rapidly

Stormwater offers a different type of operating situation. When it is dry the stormwater lift station may not see much use. However, during severe weather conditions, the station can see a significant increase in activity. The station can be part of a larger flood control treatment, detention or drainage plan, making the surrounding stormwater plan an important element of the design.

Romtec Utilities takes into consideration elements like the flow rate that is required as well as head conditions, the size of the system as well as the needs of the location and environmental concerns in the design of these systems.

A station for a commercial project could, therefore, appear very different from one designed for municipal stormwater use.

Both head conditions and flow are vital.

The issue of moving 1,000 gallons not the only challenge for engineers. Engineers need to be aware of where the water is going to go and what kind of resistance they will have to overcome with the pumping system.

Variations in elevation, piping design discharge conditions, and other aspects of the system influence the head conditions in which pumps work.

The connection between head and flow is the reason why choosing a pump based on a capacity rating doesn’t suffice. The technology of the pump and station configuration should be designed to meet the hydraulic requirements of the complete application.

Create the station to meet the conditions it will actually be exposed to

Romtec Utilities develops customized pumping systems for stormwater, wastewater clean water boosters, industrial, and other applications. Its procedure can comprise preliminary design and budgeting, complete plan sets as well as documentation and startup, testing and commissioning.

The principle of engineering that underlies it is quite simple: genuine pumping systems don’t go through their entire lives working under one comfortable set of rules.

They have to contend with changing demands, flows and project-specific hydro requirements. It is vital to develop a station to handle this reality.
