Applications and Usage

The Paxton CT2200JB is designed for permanent below-ground installation across a broad range of residential, commercial, and agricultural applications. Its 10,000-litre capacity makes it one of the largest single-unit underground storage solutions in the Paxton water tank range, suited to properties requiring significant water reserves — including large rural dwellings, farms with high livestock water demand, commercial premises, and rainwater harvesting systems supporting irrigation or toilet flushing. WRAS approval confirms the tank meets the standards required for contact with drinking water, making it equally suitable for human consumption applications and non-potable uses. The one-piece MDPE construction eliminates internal joints and seams, removing potential points of ingress or contamination and ensuring long-term structural integrity below ground. Built-in lifting lugs simplify safe installation using standard plant equipment, and the flat outlet area makes attaching pipework, valves, and fittings straightforward. The included Byelaw 30 kit provides the screened overflow, screened vent, and vent plug required for compliant potable water installations in the UK.
