The 500 Litre Underground Potable Water Tank – WBV2 is a compact, low-level water storage solution designed specifically for properties with limited underground space. With its slim footprint and two 4" inlet/outlet connections, it is ideal for integrating into underground pipework systems for efficient potable water storage.

Made from durable High Density Polyethylene (HDPE), it includes a 12" access lid suitable for installing a submersible pump, providing an easy way to supply water for garden watering, vehicle washing, or general household use. A pre-moulded 1" BSP outlet ensures quick and reliable plumbing connections. Designed for long-term strength, weather resistance, and underground performance, this 500-litre tank is an excellent choice for domestic, commercial, and industrial potable water storage where space is restricted.
