Each pumping station was equipped with thirty diesel-powered reciprocating pumps with a capacity of 180 long tons (180 t) per day, and four large Byron Jackson Company electric centrifugal pumps capable of 3,500 long tons (3,600 t) per day, which worked out to 400,000 imperial gallons (1,800,000 l) at 1,500 psi (10,000 kPa).[28][29] Both stations were fed from the Avonmouth-Thames pipeline, which had a capacity of 135,000 long tons (137,000 t) per month. A 70-mile (110 km) branch line was constructed connecting Dungeness with its eastern terminal at Walton-on-Thames. Sandown was connected to the system through a 22-mile (35 km) link between the Isle of Wight and Fawley Refinery.
