Western Pumping Station, London Embankment, Thames Water

ICR was commissioned by TW to undertake a high level condition survey of the external and internal cast iron and wrought iron structural and decorative elements of the engine house roof and chimney. The final documentation also included a conservation method statement for repair and a materials technical specification 

The pumping station was built in 1875 and was designed to supply an integral element of London’s sewage disposal capability.

The chimney is of a classic Italianate design utilising predominately traditional brick and stone construction with integral decorative and structural ironwork. It comprises a tapered square brick outer tower encasing a circular smoke flue. Internal access is via a cantilevered spiral staircase naturally illuminated by vertical light openings.

Although the chimney no longer provides its primary function as an exhaust gas smoke flue it still acts as a ventilation shaft
