Large-scale storage & surface water management

Long-life modular tanks for fire protection, emergency supply, cooling and thermal energy storage - plus wastewater and surface water solutions for the wider site.

We help specifiers, owner/operators and contractors deliver high-performance, compliant and long-lasting storage and water management solutions for hyperscale and colocation data centres worldwide.

The Permastore Advantage for Data Centres

Technical market leader in Glass-Fused-to-Steel (GFS) and Fusion Bonded Epoxy modular bolted tanks, proven in harsh environment for over 60 years.

Unmatched Service Life and Resilience

GFS and epoxy coatings deliver a 50+ year service life, well beyond painted or welded tanks. The inert coating resists corrosion, removing cooling water storage's top risk: maintenance downtime.

Accelerated, Predictable Construction

Modular, bolted GFS and epoxy tanks arrive pre-engineered and erect fast, regardless of weather or local trade availability.

Optimised Footprint

Higher strength-to-weight lets tanks stand taller on a smaller footprint than concrete, maximising storage per square metre.

Certified Quality and QC

Tanks are fused and coated in a controlled, ISO-certified factory, removing the variability of on-site welding or concrete pours

High-Volume Thermal Energy Storage

Built for large-volume chilled water buffers, with an inert lining that handles continuous cycling and eases the load on treatment.
