The 280 Litre Underground Water Tank is a slim, space-saving solution designed for properties where above-ground storage isn’t practical. Built from strong, virgin polymer using a one-piece mould, this underground tank delivers exceptional durability and long-term performance. It includes two 4" connections for easy integration with standard UK underground pipework, making it ideal for rainwater harvesting, garden irrigation or car washing setups.
Fully rotationally moulded and manufactured in the UK, this compact tank features an extended neck (which can be cut to size) for flexible installation, a 12" access lid suitable for submersible pumps and a pre-moulded 1" BSP outlet for straightforward pump or hose connections. Multiple tanks can be connected together using 4" drainage pipe, offering an expandable and reliable underground storage solution.
