It would make engineering much easier if all water moved at the same rate.

It’s not.

The amount of water that goes into a water system may fluctuate throughout the day. Commercial and industrial facilities could be operating at peak times. Stormwater flow is affected by weather conditions. The need for clean water also varies in relation to its use.

It is not enough to select equipment that can meet a certain flow rate when designing the pumping station. Engineers must know the potential conditions under which the system could be utilized.

Be aware of operating conditions and not just the maximum capacity

The flow that is the highest in importance however, it is just part of the station’s operation. Imagine that a wastewater treatment facility was designed to handle a high peak flow. The majority of the time the flow coming in is less. During normal operating hours, the station should still be functioning properly.

This leads to questions on wet-well sizes, pump operation controls, head conditions, and how the equipment responds when demand changes.

A well-engineered package pumping system brings these considerations in line with the requirements of the location, instead of considering the maximum capacity of the pump as the primary design goal.

Wastewater Has Its Own Daily Theme

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

The system must collect the wastewater and turn on its pumps in accordance with the control strategy established for the station. The structural dimensions, the pumping equipment, piping and pumps along with electrical components and controls all play a the role in this procedure.

Design could also incorporate different considerations specific to the location. Romtec Utilities is able to incorporate auxiliary equipment such as grinder vaults and odor control equipment, depending on the application. This results in a station which is specifically designed to suit the project, rather than being a standard design applied to all wastewater sites.

Stormwater changes much more quickly

Stormwater is a completely different process. When it is dry the stormwater lift station might not be used much. However, during extreme weather conditions, the station is likely to witness a significant rise in activity. The station might be a component of a larger flood control strategy or as a detention, treatment or drainage plan.

Romtec Utilities evaluates factors including flow rates that are required and head conditions, system size the site’s requirements, as well as environmental considerations when developing the systems.

Stations that serve commercial developments could appear very different from the ones designed for municipal stormwater systems.

The Head Conditions are Important along with Flow

The ability to move 1,000 gallons is just part of the engineering problem. Engineers also have to understand the direction of the water and what resistance the pumping system must overcome.

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

This connection between flow and head is another reason that choosing an appropriate pump solely based on its rating is not enough. The technology of the pump and station’s configuration should be aligned to the conditions of hydraulics to be used for the entire process.

Create a design for the conditions the Station will Experiece

Romtec Utilities designs and develops custom pumping systems to meet the needs of wastewater, stormwater management and clean water, industrial applications, boosters, and much more. The process starts with initial design plans, budgeting, set-ups along with system components, documentation, startup and testing.

The principle behind engineering is that a real pumping systems can’t function under a single condition.

They must contend with shifting flows, changing demand and specific hydro requirements for projects. A successful station must be engineered for that reality.
