Climate change is no longer a distant concern. It is something that is already affecting buildings, infrastructure, and essential services across the UK. Many building owners overlook how changing weather patterns are increasing the demands on water tanks. Higher temperatures and heavier rainfall are changing how teams maintain, inspect, and protect water tanks.
One of the most noticeable impacts is the rise in average temperatures. As temperatures rise, bacteria and biofilm grow more quickly inside water tanks, especially in cold water storage systems designed for cooler climates. As temperatures increase, the risk of contamination also rises. This means more frequent inspections, cleaning, and disinfection are becoming essential to maintain water quality and remain compliant with health and safety guidance.
Increased Rainfall
Heavier and more frequent rainfall is another growing challenge. Increased rainfall places added strain on tank structures, roofs, and supporting frames. Overflow systems are being tested more often, and poor drainage can allow water to pool around tank bases. Over time, this can lead to corrosion, structural movement, and deterioration of seals and linings. Regular visual inspections and structural assessments are now more important than ever, especially after prolonged periods of wet weather.
Climate change is also bringing longer dry spells followed by sudden storms. This cycle of expansion and contraction affects tank materials, particularly older metal tanks or poorly insulated systems. Repeated stress can cause cracking, joint failure, or delamination of internal linings. Proactive maintenance helps identify these issues early before they develop into leaks or system failures that disrupt building operations.
Protecting Water Tanks from Airborne Pollutants and Debris
Another key factor is air quality and debris. Stronger winds and storms carry more airborne pollutants, dust, and organic matter. This debris can enter tanks through damaged lids, vents, or overflows, increasing the risk of contamination. Ensuring tanks are properly sealed and that vents are fitted with suitable mesh and filters is becoming a critical part of modern tank management.
Energy efficiency also plays a role in climate related maintenance planning. As buildings aim to reduce their environmental impact, well maintained tanks help support efficient water usage and temperature control. Insulation, for example, not only protects tanks from freezing in winter but also limits excessive warming during hotter months. This reduces stress on the system and helps maintain consistent water temperatures year round.
Looking ahead, climate change means tank maintenance can no longer be reactive. Scheduled inspections, regular cleaning, relining when required, and improved monitoring are essential steps for protecting water systems. By adapting maintenance strategies now, building owners and facilities managers can reduce long term costs, improve reliability, and ensure their tanks are ready for the environmental challenges of the future.
Climate conditions may be changing, but with the right maintenance approach, water tanks can continue to perform safely and efficiently for years to come.
