“The point selected for the pumping station is between the railway at Trowse Station and the river Yare; and a large piece of garden ground has been purchased, and engine and boilerhouses, workshops, &c., have been erected. Adjoining the engine-well are the grating tank and penstock chamber, and with these the principal main sewer communicates. This sewer, which is 6 ft by 4 ft., is intended to be carried under the bottom of Bracondale, Carrow Hill, and along King Street to near Messrs. Morgan’s brewery, where it will receive the high-level sewer. This sewer will be from 30 ft. to 80 ft. below the surface of the ground. From this point it will be 5 ft. 3 in. by 3 ft. 6 in., and will be continued along King Street to the top of Rose Lane; here one branch will turn off to the right under Rose Lane, beneath the bottom of the river near Foundry Bridge, under the towing path, to beyond Bishopgate Bridge, where it will unite with the present outfall sewer, and receive the whole of the drainage of the northern portion of the city. From Rose Lane the main will continue to Tombland, where a branch will extend to Bishopgate Bridge, with subsidiary branches to Quay Side, &c.; it will then turn to the left under Prince’s Street, St. Andrews Broad Street, Charing Cross, and Lower Westwick Street, and will unite with the present sewer emptying itself at the New Mills. “From the end of the principal main near Messrs. Morgan’s in King Street the high-level sewer will commence with a flight of granite steps, about 30 feet in height, and continue 4 ft. 6 in. by 3 ft., gradually reducing, and carried under King Street to Rose Lane, across the Bull Ring, where it will be about 44 feet below the surface, under Opie Street, Bedford Street, Pottergate Street, West Pottergate Street, Mill Hill, Rose Valley, Mount Pleasant, Town Close Road to Ipswich Road, and will provide for the sewage of a very large district hitherto entirely undrained. “Self-acting Storm Overflows are provided at several convenient points, and also numerous shafts for access to, and ventilation of, the sewers. At the pumping station at Trowse the sewage, after passing through gratings to prevent sticks and other substances from choking the pump valves, will pass into the engine-well, from whence it will be pumped through cast-iron pipes 20 inches in diameter, laid under the Kirby Road to near the cross road leading to the Bungay Road, and then be led in a main conduit across the centre of the land hired by the Board, and by means of small feeders to every part of the farm.
