NEW GAS-HOLDER
HUTT BOARD'S ACQUISITION
To have achieved during the war a very substantial increase in its plant, especially as the whole of the material had to be imported, stands to the credit of the Petone and Lower Hutt Gas Board, which today formally brought its new gas-holder into operation. Preliminary steps had been taken before the war, but it was not till November, 1940, that the board was able to invite tenders. In March, 1941, the board accepted the tender of Messrs. Clayton, Son, and Co., Ltd Leeds, England, for the supply and erection of a gas-holder to cost eh* 17,487.
The material arrived in two consignments in January and June, 1942, and m spite of sea-transit dangers not a single bolt was missing. In the meantime the concrete foundations had been laid by Messrs. A. G. Wells, Ltd., at a cost of £1050. Since then construction has proceeded steadily, the final operation being the filling of the water seal, requiring 858,000 gallons of water, weighing 3830 tons. As the steel structure itself weighs 185 tons, the total weight borne by the foundations is 4015 tons.
The holder has a capacity of 250,000 cubic feet. The inner and outer lifts of the holder have a diameter of 80ft 2Jin and 82ft 4£in respectively, and the steel tank in which they float is 84ft in diameter and 25ft 6in deep. The foundation is 87ft in diameter.
The new holder will not only provide extra storage and give improved pressure, but will tend to more even working of the plant, as the continuity of production of gas has been dependent on holding capacity. Communication between the three holders has been arranged, and any one holder may be cut out at will.
The use of the new holder should maintain pressure even at times of heavy draw-off. The heaviest drawoff occurs not at industrial peaks, but on Saturday and Sunday—especially Sunday—mornings, and this in spite of the fact that several industries are very large consumers of gas and that these do not work on Saturdays or Sundays.
