The 350 Litres Underground Potable Water Tank V is a compact and slimline underground water storage solution designed for properties with limited space. Perfect for safely storing drinking-quality water, this tank features a narrow footprint that allows it to fit easily into tight or confined underground areas.

Constructed from strong High Density Polyethylene (HDPE), the tank includes an easy-access 12" lid, ideal for installing a submersible pump for garden watering, vehicle cleaning, or general water use. It also features a pre-moulded 1" BSP outlet and two 4" connections suitable for underground pipework integration. Built for strength, reliability, and long-term performance underground, this 350-litre tank is a smart choice for domestic, commercial, agricultural, and industrial potable water storage.
