The second of two notable water towers in the East Yorkshire town of Goole. They are known locally as the Salt and Pepper Pots. Silcock's modern reinforced concrete tower (on the right in the photo) was thought to be the biggest in Europe at the time of its construction. Now heritage listed, the white painted tower was refurbished 2012-2013 and continues to feed the town’s mains water supply.
The 1927 reinforced concrete water tower was designed by engineer Edward John Silcock (1862-1953) of 10 Park Row, Leeds, to replace the supply from the neighbouring 'pepper pot' brick water tower, completed in 1885. The ‘salt pot’ tower stands on the north side of its smaller Victorian counterpart.
The new tower was constructed by Harold Arnold & Sons Ltd of Printing Office Street, Doncaster, for Goole Urban District Council. Its tanks hold 3.14 million litres of high quality drinking water for supplying the population of Goole (estimated around 20,000 people, 2017).
The structure is founded on a reinforced concrete raft 27.4m in diameter and extending 3.1m below ground level. The tower shaft consists of a cylindrical pilaster wall 14.3m in diameter, within which are four central columns, surrounded by a ring of 24 square-section columns at 25m diameter. They are joined at the top by round arches. The columns and wall are braced by five tiers of radial and annular beams.
Above the shaft sits a plain drum for the tanks, supported by the shaft and columns, and curved bracketed cornicing. A horizontal ring beam links the columns at the bracket spring points. At the top of the drum is a concrete balustrade with handrails of steel mesh panels.
The drum houses two concentric concrete tanks. The inner one is 10.4m in diameter and the outer 27.3m, with a 305mm diameter penstock to connect the two. Both tanks impound water to a depth of 6.1m, with a top water level 43.7m above ground. The 254mm thick tank floors sit 37.6m above ground and the 127mm thick tank roofs are at 44.3m. The tank walls taper from 254mm wide at the bottom to 178mm at the top.
Steel staircases inside the shaft lead to the tanks, and ladders through the centre of the inner tank provide access to the roof, the tank hatch covers and hooked overflow pipes. Inlet and outlet pipes of 381mm diameter are set into the tank floors. The washout and overflow pipes are of 229mm diameter.
The new tower cost £21,310 to construct and went into service on 23rd February 1927. It was Grade II listed in September 1987.
In 2012-13, as part of ongoing maintenance to ensure the tower’s longevity, Yorkshire Water undertook repairs to cracked and spalled areas of concrete. Some 1.5km of scaffolding was erected around the tower in September 2012. The repairs cost an estimated £420,000 and were completed by October 2013.
The high-strength non-toxic cementitious repair mortar chosen for the work is approved under Regulation 31(4)(a) of the Water Supply (Water Quality) regulations for materials in contact with potable water, and complies with European standard EN1504 for concrete repair. About 6 tonnes of the mortar were used.
