7000 Litre Underground Water Tank

The 7000 Litre Underground Water Tank is a high-capacity, space-saving solution designed for efficient rainwater harvesting in both domestic and commercial settings. Installing an underground tank keeps your water supply protected, out of sight and stored at a stable temperature all year round. Unlike above-ground tanks, this system eliminates visual clutter while safeguarding your water from weather damage, wildlife and vandalism.
Saving rainwater is an excellent way to reduce mains water usage, lower bills and ensure you always have emergency water available when needed. Manufactured in the UK from industrial-strength MDPE, this underground tank features a one-piece mould for superior durability, lifting lugs for easy installation and flexible inlet/outlet positioning to suit a wide range of projects. Its versatility makes it ideal for rainwater storage, chemical storage and general water management across residential, agricultural, industrial and commercial applications.
