Sectional Tanks
Tricel (Lanark) Ltd's sectional GRP tanks are modular systems designed for large-scale water storage, offering capacities from 1,000 to 2 million litres. Ideal for commercial and industrial applications, these tanks feature hot-pressed panels that ensure durability and compliance with BS EN 13280 standards. Their modular design allows easy transportation and on-site assembly, making them suitable for restricted spaces. The internally flanged base optimises space utilisation while maintaining structural integrity.
Fire Protection Tanks
LPCB-approved fire protection tanks provide reliable water storage for emergency fire suppression systems. Available in capacities up to 1,300m, these GRP tanks meet BS EN 12845 standards and are engineered to ensure consistent water pressure for sprinkler systems. Their corrosion-resistant construction guarantees long-term reliability, making them ideal for commercial buildings, hospitals, and industrial facilities requiring critical fire safety compliance.
One-Piece Tanks
Tricel (Lanark) Ltd's one-piece GRP tanks are compact solutions for residential and small commercial applications, with capacities from 45 to 16,000 litres. WRAS-approved for potable water storage, these tanks feature factory-insulated walls to prevent freezing and bacterial growth. Their seamless design reduces maintenance needs, while optional twin compartments ensure continuous water supply during maintenance periods.
Rainwater Harvesting Systems
Our GRP tanks support rainwater harvesting systems to reduce mains water dependency. Designed for both residential and commercial use, these tanks store collected rainwater for irrigation, toilet flushing, and industrial processes. The UV-stabilised gelcoat finish prevents algae growth, ensuring water quality, while modular options allow scalability for large-scale sustainability projects.
