The 15,000 Litre Underground Water Tank is a high-capacity, durable rainwater harvesting solution designed for domestic, commercial, industrial and agricultural use. Storing water underground has been practiced for centuries, and today it remains one of the most efficient ways to secure an emergency water supply while reducing reliance on mains water. This large underground tank helps prevent flooding in vulnerable areas by safely collecting and storing rainwater from roofs and surface runoff.
Manufactured in the UK using industrial-strength MDPE, this underground tank is rotationally moulded for maximum durability and long-term performance. It features a one-piece mould, extended neck, multiple inlet/outlet options up to 8", and a 600mm vented lid that provides easy access for maintenance. Its frost-proof, algae-resistant design ensures clean, reliable water storage all year round, making it a cost-effective and sustainable solution for major rainwater harvesting projects.
