Water Automation & Control Systems
Industrial Automation for Water and Wastewater Systems
Water and wastewater operations depend on reliable control systems to manage pumping, treatment, storage, distribution and associated process equipment.
PLCs, instrumentation, control panels and SCADA systems continuously monitor changing process conditions and coordinate equipment to maintain effective operation. When control equipment fails or communication with remote assets is lost, operators need clear information to identify the problem and respond quickly.
Many water systems also remain operational for decades, leaving organisations managing ageing PLCs, obsolete control panels, legacy communications and supervisory platforms that have become increasingly difficult to support.
Stratos provides industrial automation engineering for water and wastewater applications, including PLC programming, control panel manufacture, SCADA and HMI development, industrial networking, remote monitoring, integration and control system modernisation.
Automation for Water and Wastewater Systems
Automation provides the monitoring and control required across water treatment, handling and distribution processes.
Depending on the application, systems may control:
Pumping stations.
Water treatment equipment.
Wastewater processes.
Filtration systems.
Tank and reservoir systems.
Dosing equipment.
Valves and actuators.
Motors.
Variable Speed Drives.
Associated process equipment.
PLCs receive information from field instrumentation and automatically control equipment according to defined operating requirements.
This allows processes to respond to changing conditions while providing operators with visibility of the wider system.
PLC Control for Water Applications
PLCs provide real-time control across water and wastewater automation.
PLC software may manage:
Pump sequencing.
Duty and standby operation.
Level control.
Pressure control.
Flow control.
Valve sequencing.
Dosing sequences.
Equipment interlocks.
Automatic operating modes.
Alarm generation.
Fault handling.
Stratos develops and modifies PLC software around the requirements of the process and equipment.
Structured programming and clear diagnostics can also make the system easier for engineering teams to troubleshoot and modify throughout its operational life.
Water and Wastewater Control Panels
Industrial control panels house the electrical and automation equipment responsible for operating pumps, motors, valves, instrumentation and associated water infrastructure.
As a control panel manufacturer, Stratos can design and manufacture control panels around the requirements of the wider process.
Panels may incorporate:
PLC hardware.
Remote I/O.
Variable Speed Drives.
Motor controls.
Protective devices.
Industrial networking equipment.
Power supplies.
Relays and contactors.
Instrumentation interfaces.
Operator controls.
Existing panels can also be assessed for refurbishment, modification or replacement where ageing equipment is becoming difficult to maintain.
Pumping Station Automation
Pumping systems need to respond automatically to demand while protecting equipment and maintaining appropriate operating conditions.
Automation may provide:
Duty and standby sequencing.
Multi-pump control.
Automatic changeover.
Level-based operation.
Pressure control.
Flow control.
Variable speed operation.
Pump fault monitoring.
Runtime balancing.
Failure response.
Where one pump becomes unavailable, the PLC may automatically bring alternative equipment into operation according to the defined control strategy.
Operational information can also be communicated to SCADA to provide wider visibility of pump condition and availability.
Instrumentation and Process Control
Water automation depends heavily on accurate field instrumentation.
Depending on the process, instrumentation may measure:
Flow.
Pressure.
Level.
Temperature.
Water quality parameters.
Equipment position.
Tank conditions.
Other process values.
The PLC uses these measurements to determine how pumps, valves, drives and other equipment should respond.
Instrumentation faults can therefore affect both process visibility and automatic control.
Clear PLC diagnostics and SCADA information can help operators distinguish between an actual process condition and a potential instrumentation problem.
SCADA for Water and Wastewater
Water infrastructure often contains equipment distributed across treatment areas, pumping stations and remote locations.
SCADA provides centralised monitoring and supervisory control across these systems.
Depending on the application, operators may be able to view:
Pump status.
Tank and reservoir levels.
Flow information.
Pressure.
Process conditions.
Valve positions.
Active alarms.
Equipment faults.
Historical trends.
Communication status.
SCADA can help operators understand the wider condition of the water system rather than relying on individual local control panels.
Remote Monitoring of Water Assets
Pumping stations and other water infrastructure may be located away from permanently staffed facilities.
Remote monitoring can provide authorised engineering and operational teams with greater visibility of these assets.
Information may include:
Pump status.
Tank levels.
Flow.
Pressure.
Equipment availability.
Instrument values.
Active alarms.
Communication status.
Historical information.
This can provide earlier awareness of abnormal operating conditions and help teams determine the nature of a problem before attending site.
Remote connectivity should be implemented alongside appropriate access controls, industrial network architecture and cyber security measures.
Variable Speed Drives and Motor Control
Pumps and motors represent a significant part of many water automation systems.
Variable Speed Drives allow motor speed to be adjusted according to process requirements.
Applications may include:
Pressure regulation.
Flow control.
Pump speed control.
Controlled acceleration.
Controlled deceleration.
Multi-pump systems.
Equipment sequencing.
Integrating drives with PLC systems can also provide additional diagnostic information, including operating state, speed and fault conditions.
This information can be presented through HMI or SCADA systems to improve equipment visibility.
Industrial Networking and Distributed Water Systems
Reliable communication is essential where PLCs, instrumentation and supervisory systems are distributed across water infrastructure.
Industrial networks may connect:
PLCs.
Remote I/O.
SCADA.
HMIs.
Variable Speed Drives.
Instrumentation.
Control panels.
Remote assets.
Existing water infrastructure may contain multiple generations of communication technology.
Stratos can support industrial network integration, modernisation and fault finding, helping new and existing automation equipment exchange the information required for reliable operation.
Modernising Water and Wastewater Automation
Water infrastructure can remain operational far longer than some of the automation equipment used to control it.
Over time, organisations may encounter:
Obsolete PLCs.
Ageing control panels.
Unsupported HMIs.
Legacy SCADA platforms.
Obsolete Variable Speed Drives.
Legacy communications.
Unsupported engineering software.
Missing software backups.
Incomplete electrical documentation.
Complete process replacement is rarely necessary simply because the automation equipment has become obsolete.
Stratos can assess the existing control environment and develop a phased modernisation approach, prioritising equipment according to condition, supportability and operational importance.
Water Automation Maintenance and Lifecycle Support
Water automation systems need to remain reliable and supportable throughout long operational lifecycles.
Planned support may include:
PLC health checks.
Control panel inspections.
SCADA and HMI reviews.
Drive checks.
Industrial network checks.
Software backup verification.
Obsolescence monitoring.
Documentation updates.
Automation fault finding.
Planned modernisation.
Where ongoing engineering support is required, maintenance and service contracts can provide a structured approach to maintaining PLCs, control panels, SCADA and associated water automation systems.
Regular lifecycle reviews can also help identify ageing equipment before obsolescence becomes an urgent operational problem.
