Kaiapoi pipeline work in August

More than $5OOO worth of plastic pipe will be sunk in the Waimakariri riverbed to give Kaiapoi an extra link in its sewerage pipeline. The piping is part of 1300 m of asbestos cement pipe that will form a rising main from the No. 1 pumping station in Giles Street across the river and the North Canterbury freezing works paddocks joining the existing system near Ohoka Road.

A 2m-deep trench would be dug in the riverbed to ensure that the pipe sits at least 1.5 m below the bed surface, the chairman of the Kaiapoi Borough Council’s work committee, Cr J. Bryden, told the committee. The pipeline, which will provide a sewerage system for a new residential development in the town and for the freezing works, will cost $60,450 to install. A section of the river will be closed for two weeks to allow the pipe to be laid by March Construction. The company would provide two divers to guide the pipe into the trench and ensure that it settled properly, said Cr Bryden. It was a tricky operation, he said. The job would be done in August and had been timed to coincide with the lowest tide for quite some time. The river would be closed for a fortnight from August 4. Cr H. G. McAllister said that he was worried about the size of the pipe being used.

“We have had problems in the past with pipes that could not carry the amount of water required. I am afraid this one could face the same problem,” he said. Councillors resolved to ask the project engineers for assurances that the Class B pipe selected would adequately cope with increased demand in the future. Refuse

Kaiapoi’s rubbish will not go up in smoke. A report on

incineration of the ’ town’s rubbish was received at the meeting, but no action taken.

The report outlined the possibility of burning the rubbish and using the energy produced.

The town’s collection totalled about 16,650 kg a week. After subtracting recyclable material and adding trailer-loads delivered to the tip, the total would be about 15,000 kg, said the engineers’ report.

An incinerator with a burning rate of 580 kg an hour would take 26 hours to burn that amount of rubbish. It could be used at a time that was convenient. That amount of rubbish would produce substantial amounts of energy. Ideally the incinerator, heat-recov-ery unit, and the energy user would be sited together. One energy user suggested that the freezing works could be supplied with hot water. The incineration scheme would cost $280,000 to establish, more than half of that made up of the cost of the incinerator and buildings. There was finance available for projects such as the incineration scheme from energy conservation loans, said the report. Collection Councillors also discussed another section of its rubbish system. Mogal Bin Services, Ltd, which also collects the town’s residential rubbish, has asked for an increase of 15 per cent in its charges to collect to trade rubbish.

An iterim arrangement of 10 per cent of the total contract amount of about $13,000, had been agreed to by the council on a month’s trial basis. Councillors had set each business’s costs at no more than $l5 a collection. “I know of many businesmen who would be more than happy to pay more

because it would still be cheaper than disposing of it themselves,” said the Town Clerk, Mr R. N. McCabe. Twenty five per cent of the contract total would be $4OOO to $5OOO, said the Mayor of Kaiapoi, Mr H. W. Cumberland.

“Perhaps we should be looking at our people doing it themselves for that amount,” he said. Councillors decided to negotiate with the refuse company on the price. Domain

North Canterbury’s first gazetted domain in Kaiapoi will be given a facelift if a plan presented to the reserves and harbour committee is supported.

The committee’s chairman, Cr McAllister, outlined a five-year to 10-year plan of planting and development for the domain, which was gazetted in 1873. The plan, drawn up by Mr Warwick Scadden, curator of the Botanic Gardens, would make the domain a more pleasant place, said Cr McAllister.

Gardens A public meeting will be held on July 20 to form a steering committee to organise Kaiapoi’s first street garden competition.
