Field surveys of Thames Water's distribution mains found the occurrence of ‘red water’ to be highly variable and localized. To model the many inter‐related factors identified in the field, a controlled pipeline‐testing facility was required to simulate conditions in a ‘live’ network, but on a pilot‐scale. This was achieved by incorporating a specialized red‐water testing facility into an existing experimental pipeline. This paper describes the hydraulic and material design features, including the addition of a ‘dead‐end’ section operated on a stagnation and flow regime, quantified using computational fluid dynamics. Following commissioning, the facility has provided detailed, time‐sequenced observations on corrosion‐deposit development and red‐water generation under different hydraulic regimes.
