Waterways

FAIRFIELDS delivers integrated MEICA solutions for waterways infrastructure, supporting the safe, reliable operation of assets that protect communities from flooding and keep rivers and canals navigable.

Waterways infrastructure operates in environments where reliability is critical and failure carries real operational and safety consequences. Assets such as locks, sluices, gates, barriers and pumping systems play a vital role in protecting homes and businesses from flooding while maintaining safe, navigable routes for commercial and leisure users.

These systems must operate reliably across changing water levels and operational conditions, often within the constraints of ageing mechanical and electrical equipment. Many are located in remote or constrained environments, where access is limited and outages must be carefully planned around operational and environmental conditions.

FAIRFIELDS supports clients across the full lifecycle of these assets, from feasibility and front end design through to installation, commissioning and long term maintenance. Our multidisciplinary team brings together mechanical, electrical, control, instrumentation and hydraulic expertise to deliver practical, maintainable solutions aligned to real operating conditions.

We have worked on assets across the UK’s river and canal network, from sea locks and integrated water management systems for Scottish Canals to tidal barriers and multi site flood alleviation schemes for the Environment Agency. This experience informs how we approach delivery, balancing engineering requirements with operational realities.

We operate flexibly within project environments, working as a subcontractor within main contractor teams, delivering directly for asset owners on engineering led projects, and supporting long term frameworks, including over 20 years on Environment Agency MEICA frameworks.

Integrated Delivery

Waterways projects rarely sit within a single discipline. Mechanical structures, hydraulic systems, electrical infrastructure and control systems must operate together, often within constrained sites and under strict operational conditions. Coordinating these interfaces is critical to successful delivery.

FAIRFIELDS manages projects from early concept through to commissioning and handover, ensuring each stage is aligned to the operational requirements of the asset. This includes feasibility studies, asset assessments and option development, followed by detailed design, procurement, installation and commissioning.

Our approach reflects the realities of working around live waterways infrastructure. Works are often delivered within restricted access windows, seasonal constraints and operational shutdown periods, requiring careful planning to minimise disruption to flood protection and navigation.

We coordinate mechanical, hydraulic, electrical and control systems as a single engineering solution, ensuring interfaces are clearly defined and systems operate together as intended. This includes integration of drive systems, actuation, control panels, instrumentation and monitoring systems.

The result is infrastructure that performs reliably in operation, protects surrounding areas from flood risk and maintains safe passage for waterway users.

All Shapes and Sizes

Waterways infrastructure includes a wide range of asset types, each with specific operating characteristics, mechanical arrangements and control requirements. Many assets are bespoke, developed over decades, requiring tailored engineering solutions to maintain and improve performance.

FAIRFIELDS supports systems of varying scale and complexity, from targeted upgrades through to full asset refurbishment and replacement. We work across both new build and legacy infrastructure, adapting solutions to suit the operational context and constraints of each site.

Typical assets and systems include:

Flood alleviation and defence systems
Integrated water management systems
Sea locks and navigation locks
Tidal barriers and storm gates
Level and flow control systems
Penstocks and sluice gates
Rising spindle sluice gates
Fish belly gates
Tilting weirs and beamless weirs
Guillotine gates
Mitre gates
Sector and radial gates
Flap gates and caisson gates
Pumping stations and associated MEICA systems

These systems are typically driven by hydraulic or electromechanical arrangements, often with single or multiple actuation points depending on duty and scale.

Our role is to ensure each asset operates safely and reliably, supporting both flood protection and the continued safe navigation of waterways.

Maintenance and Support

Ongoing maintenance and support are critical to the reliability and availability of waterways infrastructure. Many assets operate continuously or are required to respond immediately to changing environmental conditions, making unplanned downtime unacceptable.

FAIRFIELDS provides structured lifecycle support tailored to each asset. Planned preventative maintenance programmes help ensure systems continue to protect communities from flooding while maintaining availability for navigation.

We offer 24/7 support with defined response times, ensuring faults are addressed quickly and effectively. Where systems allow, remote diagnostics provide real time visibility, enabling faster fault identification and reducing the need for site attendance, particularly for remote or difficult to access locations.

Our support also includes obsolescence management, helping clients plan upgrades as components reach end of life. This ensures continued reliability while aligning investment with operational and budgetary constraints.

By bringing together multidisciplinary engineering expertise, we provide a coordinated approach to asset support, maintaining safe operation, improving reliability and extending asset life.
