GRP Water Storage Tanks for UK Data Centres: The Most Reliable Choice for Cooling and Fire Resilience
Data Centre GRP Tanks Installation:
For UK data centres, GRP delivers 25 – 30 year lifespan, low maintenance, lightweight panels for constrained spaces, WRAS/BS EN 13280 potable compliance, and LPCB aligned options for fire storage—at ~£200–£400/m³. Modular build enables weekend installation and redundancy via multi tank arrays.
Why material selection matters
Your tank material influences lifecycle cost, hygiene, structural loads, installation time, and insurance acceptance. The Tricel Guide shows GRP as the optimal choice for most datacentre applications because it combines long service life, corrosion immunity, low weight, and modularity with UK approvals.
GRP vs alternatives
- GRP (GlassReinforced Plastic): 25–30 years, ~£200–£400/m³, very low maintenance, 15–25 kg/m³, ideal for cooling/fire storage.
- Coated steel: 15–20 years, £300–£500/m³, higher maintenance and corrosion risk.
- Concrete: 50+ years, £400–£700/m³, heavy and suited to large belowground builds.
- Stainless steel: 30–40 years, £600–£900/m³, premium for potable/hygienic duties.
Compliance & assurance
- Potable storage: WRAS/Regulation 4(1)(a) approvals; BS EN 13280 for coldwater storage.
- Fire storage: Sized to BS EN 12845; insurers often expect LPCB/LPS alignment for sprinkler suction tanks.
- Hygiene & Legionella: Follow BS 8558 + HSE L8 regimes; GRP designs support sealed lids, screened vents, and appropriate linings.
Water System Specification Checklist for Data Centres
This System Specification Checklist provides a comprehensive framework for designing or procuring water storage solutions for data centres. From capacity sizing to hydraulic design, treatment systems, certifications, and monitoring, it ensures every critical requirement is captured.
Installation advantages of sectional GRP
- Modular panels pass through standard doorways; ideal for retrofit plant rooms (IFB/EFB/TIF formats).
- Fast build: 3–10 days for 18–500 m³; larger arrays in 2–4 weeks; many projects complete over a single weekend shutdown.
- Designed for redundancy: easy to configure multi tank arrays (compartmented or parallel) to eliminate single points of failure.
Procurement checklist
- Duty (cooling/fire/potable), autonomy hours, and required total m³.
- Compliance: Reg.4/WRAS (potable), BS EN 12845 (fire), LPCB/LPS (if insurerrequired), BS EN 1717 airgap/backflow.
- Configuration: sectional IFB/EFB/TIF, headroom limits, base steels, compartments.
- Instrumentation: level/flow/quality sensors, leak detection, BMS protocols (Modbus/BACnet/SNMP).
- Maintenance plan: inspection/testing schedule (weekly/monthly/quarterly/annual), cleaning access, recordkeeping (HSE/BS).

Frequently Asked Questions
Yes insulated covers, screened vents, and encapsulated foam help maintain temperature and hygiene; EFB designs allow fully self draining bases.
From 1,000 L to multi million litres, with height limits and panel increments to suit the space; no restriction on plan dimensions for sectional assemblies.
Typical installations: 3–10 days (18–500 m³) or 2–4 weeks (500–5,000 m³), plus commissioning/testing and operator training.
It’s excellent for potable/hygienic duties but carries higher capital cost and weight than GRP; for cooling/fire storage, GRP typically provides the best lifecycle value.
Yes modular GRP supports phased capacity growth and retrofits without major structural works.

Cold Water Storage Tank Compliance in the UK: Regulations, Standards & Best Practices
Ensuring compliance with cold water storage tank regulations in the UK is essential for safeguarding water quality, maintaining system efficiency, and meeting legal obligations. From WRAS approval and LPCB certification to industry standards such as BS EN 13280, strict requirements govern the design, installation, and maintenance of water tanks.
How to Maintain a Compliant Cold Water Storage Tank
Maintaining a cold water storage tank is not just about ensuring a reliable water supplyit is also a legal and safety requirement. A poorly maintained tank can pose serious risks, including bacterial growth such as Legionella, structural deterioration, or non-compliance with current regulations.
Leak in Water Tank: Causes, Prevention, and Solutions
Water tank leaks can lead to significant structural damage and water loss. Common causes include corrosion, poor installation, and lack of maintenance. To prevent leaks, it's essential to ensure proper installation, use high-quality materials, and conduct regular inspections. For detailed guidance on causes, prevention, and solutions for water tank leaks, refer to Tricel Water UK's comprehensive article.
Importance of Base Levelling Steels
Proper base levelling is essential for the stability and longevity of your water tank. This guide explains why base levelling steels are crucial for preventing structural issues and ensuring your tank performs optimally over time.
