In January 2026, the United Nations declared global water bankruptcy — a condition in which repeated water crises become chronic states, with river basins and aquifers losing the ability to return to their historical norms. England faces a 5 billion litre daily water shortfall by 2055. Water scarcity could cost the UK economy £25 billion over five years. The infrastructure being built today to treat, move, and conserve water must last 50 years in the most chemically aggressive environment in civil engineering. FRP is the secondary infrastructure specification that makes that possible.

The United Nations published a landmark water bankruptcy report in January 2026, defining water bankruptcy as a condition in which persistent shortages and damages mean that water systems can no longer return to their historical baselines. Around 4 billion people already experience severe water scarcity for at least one month each year (House of Commons Library, 2026). The UN found that many countries and cities are living beyond their hydrological means, a situation exacerbated by climate change, over-abstraction of groundwater, deforestation, and pollution incidents. Tehran is in its sixth consecutive year of drought. Cape Town spent years counting down to Day Zero. These are not distant problems that do not affect the UK.
England faces a public water supply shortfall of 5 billion litres per day by 2055 without urgent action, according to the Environment Agency's National Framework for Water Resources, published June 2025 (GOV.UK, 2025). The shortfall is equivalent to a third of England's current daily water use. Climate change, population growth, and environmental pressures are already affecting supplies, with Sussex, Cambridgeshire, Suffolk, and Norfolk among the areas where water supply shortfalls are already being felt today, constraining housing development and business growth (House of Commons Library, 2026). The Chartered Institute of Water and Environmental Management estimates water scarcity could cost the UK economy £25 billion over the next five years due to halted housing developments alone (House of Commons Library, 2026).
The response to this challenge requires a sustained, large-scale programme of water infrastructure investment. The £104 billion Ofwat-approved investment programme for 2025 to 2030 is the largest water capital programme in UK history. The Clean Water Bill, advancing through Parliament, is creating a tougher regulatory framework for water infrastructure performance. New reservoirs, treatment works, distribution upgrades, and wastewater processing facilities are being planned and built across the country. Every one of those assets is a 50-year infrastructure commitment, and every one operates in the most chemically aggressive environment that civil and industrial engineering encounters. The secondary infrastructure inside those assets, the grating, walkways, cable management, and structural systems that allow water treatment works to function safely and be maintained across their operational lives, must match that 50-year commitment. FRP is the specification that delivers it.
Why Water Treatment Is the Most Demanding Infrastructure Environment for Secondary Materials
A water treatment works is a persistently hostile environment for secondary structural materials. Chlorine dosing for disinfection creates an atmosphere of chlorinated compounds at concentrations that attack zinc coatings on galvanised steel progressively across the operational life of the installation. Hydrogen sulphide, generated by anaerobic biological processes in wastewater treatment, is one of the most aggressive atmospheric corrosives encountered in civil infrastructure, reacting with zinc to form zinc sulphide at a rate that depletes galvanised coatings substantially faster than outdoor atmospheric exposure. Persistent humidity from water surface evaporation creates the wet-dry cycling conditions that accelerate electrochemical corrosion at metal surfaces. Biological fouling from the microorganisms present in raw water and in the biological treatment stages adds a further degradation mechanism beneath fouling layers that is invisible until the fouling is removed and the damage assessed.
The NACE International IMPACT study estimated the global annual cost of corrosion at approximately £2 trillion, around 3.4% of global GDP, with water and wastewater treatment identified as one of the highest-cost sectors for corrosion management (NACE International, 2016). The UK water sector spends hundreds of millions of pounds annually on the inspection, recoating, and replacement of secondary steel infrastructure in treatment works, a recurring cost that has been built into asset management budgets because it has been treated as an unavoidable consequence of the treatment environment. It is not unavoidable. It is the consequence of specifying galvanised steel secondary infrastructure in an environment that FRP is specifically designed to resist.
FRP secondary infrastructure in water treatment environments requires no recoating, no structural replacement driven by atmospheric corrosion, and no maintenance access for secondary material upkeep across a 50-year design life. It is non-conductive around the electrical systems that control pumps, aeration, and process equipment. It is resistant to the chlorinated, hydrogen sulphide, and biological contamination of the treatment environment in all directions and across the full cross-section of the material, not just at a surface coating that can be depleted. And it provides the anti-slip access performance that treatment works safety requirements demand in the persistently wet, chemical-splash conditions of operational plant.
Where FRP Makes the Difference in Water Treatment Infrastructure
1. Grating and Walkway Systems
Access grating and walkway systems in water treatment works are among the most directly exposed secondary infrastructure on any site. They sit at or near the water surface in treatment tanks, channels, and clarifiers, where the combined exposure to chemical dosing agents, biological treatment atmosphere, and persistent moisture is at its most intense. Galvanised steel grating in these locations accumulates corrosion at the fastest rate encountered in any UK civil infrastructure application, with the chlorinated and hydrogen sulphide atmosphere attacking zinc coatings from above while biological fouling and moisture accelerate corrosion at the underside simultaneously.
FRP moulded grating provides anti-slip access flooring whose surface performance does not degrade in these conditions. The integral grit surface, bonded into the moulded panel during manufacture, maintains consistent slip resistance across 50 years of wet, chemical, and biological exposure without the surface treatment maintenance that metal grating alternatives require. The through-section chemical resistance of FRP moulded grating means that even where the grating surface is damaged or abraded by operational activity, the material beneath is no more vulnerable than the surface — there is no surface treatment to breach and no underlying metal to expose (IntechOpen, 2022).
2. FRP Cable Trays for Process Control and Electrical Systems
Water treatment works are electrically intensive. Pumps, aeration systems, UV disinfection units, chemical dosing equipment, and process monitoring and control systems all require power distribution and data cable management across the operational footprint of the site. That cable management sits in the same corrosive atmosphere as every other secondary material on the site, exposed to the chlorinated air and hydrogen sulphide that accelerate galvanised steel corrosion in treatment environments.
FRP cable trays are non-conductive around the electrical systems they serve, eliminating the earthing and bonding requirements of steel cable management in proximity to the pumping and process electrical equipment that water treatment depends on. They are corrosion-immune in the treatment atmosphere across a 50-year design life, providing maintenance-free cable management that does not generate the inspection, recoating, and replacement programme that steel cable trays require in the same environment. As the Ofwat investment programme drives upgrades across the UK water estate, the cable management infrastructure being specified on these projects should match the 50-year operational horizon of the sites it serves. FRP delivers that match.
3. Structural Profiles for Access Platforms and Secondary Framing
Process equipment in water treatment works, including pumps, mixers, aerators, and chemical dosing units, requires elevated access platforms and secondary structural framing that supports both the equipment and the operatives who maintain it. These structural elements operate in the same corrosive atmosphere as the grating and cable management, and they carry the additional structural demand of equipment loading and dynamic forces from rotating machinery. Galvanised steel structural sections in treatment works environments require periodic structural assessment because section loss from corrosion reduces load capacity over time, in ways that may not be visible without specialist inspection.
FRP pultruded structural profiles, I-beams, C-channels, and box sections, provide structural framing for access platforms and equipment supports that does not lose section through corrosion at any point across a 50-year operational life. They are lighter than equivalent steel sections, approximately 75% lighter, making installation and modification easier in the confined and access-restricted environments of operational treatment works where heavy plant is difficult to deploy. And they are non-conductive around the electrical equipment they support, eliminating the earthing and bonding requirements that metal structural frames generate in proximity to process electrical systems (IntechOpen, 2022).
The Water Scarcity Context and What It Demands From Infrastructure
The water scarcity challenge the UK faces over the next three decades is not just a resource management problem. It is an infrastructure problem. The Environment Agency's National Framework for Water Resources, the £104 billion Ofwat investment programme, and the Clean Water Bill advancing through Parliament all converge on the same practical requirement: the UK needs more water treatment and distribution capacity, built to last, and it needs the infrastructure supporting that capacity to perform reliably across the full operational life of the assets without generating the maintenance demands that divert investment from new capacity to keeping old infrastructure operational.
Water scarcity in England is already constraining development. Sussex, Cambridgeshire, Suffolk, and Norfolk face water-related constraints on housing and commercial growth today, in 2026, a generation before the 5 billion litre daily shortfall that the Environment Agency's modelling projects for 2055 (House of Commons Library, 2026). The water infrastructure being built and upgraded under the current investment programme is not solving a future problem. It is responding to a present one, with assets that must perform for the next 50 years as the scarcity trajectory continues to steepen.
In that context, secondary infrastructure specified in materials that require recoating at 10 to 15 years, structural assessment at 20 years, and eventual replacement before the asset's designed operational life is complete is secondary infrastructure that adds to the maintenance burden on water companies already facing their most intensive investment programme in UK history. The maintenance costs, the access events, the inspection requirements, and the operational disruption of secondary infrastructure replacement in live treatment works are costs that the water sector is already carrying from decades of galvanised steel specification in treatment environments. FRP does not generate those costs. It eliminates them, across the 50-year operational life of the asset, in precisely the environment where steel's failure to match that horizon is most comprehensively documented.
Water is becoming scarcer. The infrastructure required to treat, move, and conserve it is being built and upgraded at a pace and scale not seen before in UK history. That infrastructure must last 50 years in the most chemically aggressive environment in civil engineering. The secondary infrastructure specification decision that determines whether it does — or whether it generates maintenance liabilities that compound against the investment the UK is making to address the scarcity — is one that FRP answers conclusively.
