Evaluating Pump Controls During Wastewater Station Modernization

A pump station that’s old doesn’t need to stop functioning in order to become a cause for concern. The pump station might be able to move wastewater or stormwater every day however, it may struggle when demands are high, require more frequent maintenance or depend on control systems that are hard to maintain. It could still be functional but the initial design of the equipment may not be in line with current needs.

It is vital to recognize this distinction for municipalities, developers and facility operators when planning upgrades to infrastructure.

The Equipment that is failing isn’t the only problem

The retrofit of a water lift station should start by evaluating the entire system and not only the pump. Engineers should evaluate the wetwell, the mechanical equipment, as well as electrical parts. They must also take into consideration discharge piping as well as the needs of current pumping.

It is important to be aware of the condition of the wet well. It is possible, when the structure is in good condition, to keep it and also replace old equipment. This could reduce the construction costs as compared to the construction of a new station. Retaining existing infrastructure is only worthwhile when it is in line with the proposed improvements.

The area of service has been changed.

A wastewater station designed in the past could be used to serve more commercial and residential buildings, homes, or industrial operations.

These changes may affect the rate of flow and operational needs. Successful lift station rehabilitation therefore requires more than restoring the original equipment specifications. Engineers should evaluate their current and future flows, total dynamic head capacity of the equipment, and the operational reliability.

The answer isn’t always to get a larger pump. New equipment has to be compatible with the existing system of piping, wet wells, electric supply, controls and so on. Otherwise, improving one component can create problems elsewhere.

The criteria for stormwater retrofits for priority are different

Retrofitting an existing stormwater pumping station could bring additional concerns because runoff is influenced by surrounding development and rain. A station that serves the detention pond could experience distinct inflow patterns compared to one that receives water through storm drains. A new asphalt surface, increased parking areas or alterations to drainage infrastructure could alter the quantity and frequency of runoff entering the station.

Before recommending an upgrade of a stormwater pumping station engineers should review the drainage area in which they are contributing. They should also review the expected peak flows in the area, storage capacity and discharge conditions.

The data will allow you to determine if the station needs to be rebuilt or if the modernization of equipment is enough.

Plan for the Construction Before Interrupting Service

The operations of the station in rehabilitation is frequently forgotten. In general, wastewater systems can’t be closed without a plan for flow management.

Depending on the available space and the project’s requirements The construction process may include temporary bypass pumping or installing new infrastructure in conjunction with the operating station.

The system may be needed during an unexpected downpour. A comprehensive engineering plan comprehensive must include the sequencing of installation, temporary operation, equipment integration and commissioning and not just replacing components.

Making the completed system simpler to operate

Romtec Utilities provides site-specific engineering and supply solutions for stormwater and wastewater pumping applications.

The retrofit process will determine which electrical, structural mechanical and communications components are to be retained and which components require replacement. The company provides owners with preliminary designs and budget estimates to assist them in evaluating alternatives for their projects.

Following installation, startup testing, commissioning, operator training, and operation and maintenance documents help ensure that the station has been upgraded as per its specifications. Operators should be able maintain and understand the system following the successful rehabilitation.

Upgrade your system, not only its age

It’s not essential to replace an older pump station. Even if electrical and mechanical equipment is old there are some structures that can be beneficial for years to come. It is crucial to know what is safe and economically while ensuring that the station’s finished product is in line with current and future needs.

Owners can make better investment decisions by studying the operating conditions along with structural integrity, hydraulic and needs together.

It’s not just about trying to make an aging station perform again. It’s about making sure that the new system is ready for the task ahead.
