The short section of 600mm pipe will be partly sectioned to expose the joint so it can be seen and the joining technique explained.
The demand for water power was insatiable and within a year of laying the first 24" (600mm) falling main, an 18" (450mm) main was laid. By 1882 just 3 years after the first water power was used in the town, the council had to confront borrowing 14,000 pounds to lay a third 600mm main.
The debate was intense, as reported in the Otago Daily Times of October 10th 1882
A public meeting of the Oamaru ratepayers was held on Thursday evening to hear arguments for and against the proposed extension of the water supply scheme, which will involve a loan of £14,000. Mr Shrimski is one of the principal objectors, The Mayor stated that the proposed 24in. main would give an addition to the power they already had of 350-horse power, which, when all was let, say, at £10 per horse-power, would give an income of £3500, less £900 per annum for interest at 0 per cent, and charges, which gave £2000 profit. Towards this Mr Meek had guaranteed £700, the Woollen Company £750,and Mr Craig (timber merchant) £200, making altogether £1050 per annum, being £750 in excess of the amount required for interest and incidental charges' for about 160-horse power, leaving a surplus of power to let of 190-horse power —equal to £1900 at £10 as before stated. The Engineer, iii speaking on the matter, alluded to the fact that a year ago there was only one water-engine in the town now there was 113-horse power at work, and 200 more applied for. They could not sell this from their present main, so they either had to lay the new pipe down or refuse the applications. He further pointed out that the price charged was for theoretical horse-power, which was a quarter more than effective, and therefore 25 per cent, had' to be added to the price given; so that if £12 10s were charged for effective horse-power, £10 would be paid for theoretical. As far as Dunedin was concerned, they had no water there at all—only 6O-horse power in the town [we think this must be an error]—and they were obliged to sell at a high rate to prevent people from applying for it. Steam was at the present day worked at from £12 to £13, per horse-power. The polls to decide about the loan will take place within 10 days.
