Clause 72 states: "As the water in the Dock will have to be maintained at the necessary levels for the safe and proper working of the shipping in the Dock, the Contractor will have to allow for carrying out the excavation of the foundation and erection of some portion of the wall and work under water, by means of divers, and he must supply all necessary floats, air-pumps and pipes, diving suits and helmets, life and signal lines, electric light and lamps, moorings, anchors, buoys, ladders, life saving apparatus and medical attendance, and be responsible for the safe conduct of the diving operations."

73. "At certain tides the Company have to pump water into the Dock through the culverts which have to be extended under the Contract ; the Contractor will have to arrange his work so as to not interfere with this pumping, and the Company will not be liable for any damage caused to the works in progress or the plant being used, that may be caused by the discharge of this water into the Dock."

A photo [030] showing the inclined wall, the location of the culverts and pumping house used to top up the dock level by pumping water from the River Ely. The pumping house and pumps were still in place in 1966 but the pumps were removed for their scrap value by 1970 (by Eddie Avoth & Co. I believe).
