1950 Litre Underground Rainwater Tank

The 1950 Litre Underground Rainwater Tank is a durable, space-saving solution designed for efficient rainwater harvesting and below-ground water storage. Ideal for both domestic and commercial use, this underground tank helps reduce mains water consumption, provides an emergency water supply, and supports sustainable water management. Made from industrial-strength MDPE with a robust one-piece mould, it offers exceptional strength, long-term durability and resistance to harsh ground conditions.
With the ability to accept inlets and outlets from 8mm up to 110mm in various positions, this tank is extremely versatile—suitable for storing rainwater, greywater or even certain chemicals. Its extended neck can be cut down to achieve a flush ground-level installation, making it perfect for challenging ground types such as clay. Multiple tanks can also be connected using standard 4" (110mm) pipework, providing a flexible solution where a single large tank cannot be installed. Designed and manufactured in the UK, it comes with a 10-year warranty for complete peace of mind.
