NEW RESERVOIR

it] FOR ONE TREE HILL? '11 Is INCREASED WATER SUPPLY id 'o If Take about 1600 tons of concrete!! and 70 tons of reinforcing steel, mixH them together in the right way and, ? when water is added later, you will ' have a reservoir capable of holding 1,250,000 gallons. That is, of course,] if vou know how. !\ A successful example of the recipe t is revealed in the new reservoir. ! t situated on the eastern slopes of it One Tree Hill, which is now nearing , completion and which is destined to ( augment the water supply of the . borough and district. u

Tenders were called for the work! last October, the project being part' of the augmentation scheme which! the One Tree Hill Borough Council' has been concerned with for the! past 18 months. The water, which! is to fill the reservoir, is drawn from springs on the Onehunga foreshore. At present One Tree Hill borough! tdepends for its supply on the usei ■of a reservoir of 500.000 gallons |capacity which is situated on the; ifamous landmark at an elevation of; j-175ft above sea-level and which was erected over 40 vears ago for the o Manukau Water Board. " 0 Industrial Xeeils v | However, the consumption of;z (water in the industrial area—par-i ticularly • around Penrose—has in-! (creased so rapidly in recent :that the erection of the new reset*-'s voir, which is situated at a ,of 300 ft above sea-level, has been, T .made necessary, it will be used toi .supply the lower residential areas;t the old one will continue to a supply the higher areas. A license , was obtained in view of the fact! f that the work was considered to bo! 1 of national importance. | | The contract was let to the Rope 5 (Construction Company. Ltd., at a c jfigure of £9339 10/. However, ex- , |tras of more than £2000 have been. ,allowed, as rock, after excavation,'! 'exposed a number of cave.- and blow- 1 'outs of scoria. Messrs. Gray and 1 iWatts, consulting engineers, drew <■ jup the plans and specifications and t are responsible for supervision the work. The work was necessarily delayed } because of the caves found, other- j wise it would have been finished ■ now. As it is, it will not be long i; ibefore the reservoir will lie in use. 1 Over 6000 cubic yards of spoil had c to be excavated in the preliminary stages, more than half of this being 1 irock. ,1 i But in the near future One Tree ' 1 Hill will combine use and ornament c [in greater degree than any other 1 j landmark in Auckland. : l
