Pete keeps his nose clean

The BOP Times' reporting of a city council committee meeting has gotten right up the nose of Pete's Takeaways owner Pete Harford.
When the paper wouldn't listen to his complaint about its coverage – he came to SunLive. We took his issues to city waters consents manager John Gibbons-Davies who says Pete's right and the paper is wrong.


Pete Harford, owner of Pete's Takeaways – see video interview below.

Pete has been carting sewage sludge from the Chapel Street wastewater treatment plant across to a pumping station at Totara Street for about a year while the plant's two sludge digesters have been undergoing maintenance.
Every time a takeaway truck is filled with sludge the same volume of gas is expelled from the truck's tank into the air.
There was a particularly bad smell on a recent Monday that was a combination of two things.
The Monday sludge is stronger because it has an additional 24 hours in the pot. This is because the Chapel Street plant management gave Pete's Takeaways the Sunday off, though Pete's Takeaways can and does work 24/7 when required.
The second factor was that particular Monday, the prior load in the takeaway tanks was fish offal from Sanford Ltd. John believes residual fish odours combined with the sludge gases to produce a particularly strong sewage smell that day.
John says they are talking about designing some kind of vent exchange so the truck tank gases are taken into the plant tank, but some smells are going to continue.
There are a couple of months yet before the maintenance is completed and some replacement parts arrived from Australia.
The output of the city's sewers passes through the Chapel Street plant at a rate of about 25,000 m3 each day. It is strained, dewatered and the resulting sludge brewed in two digesters, before being pumped along to Te Maunga.
The bacteria that promote the digestion of the sludge are smelly and the gases produced also stink. Many Tauranga residents are familiar with the smell – particularly the businesses that have in the last few years moved next door.
Lately the plant has been stirred up with the de-sludging of the two digesters. The No 1 digester was de-sludged in 2008, and the No 2 digester is currently being de-sludged and is undergoing upgrades and maintenance before being put back into service early next year.
Much of the methane gas produced is burned to heat the digesters and produce electricity. In summer there is more gas than required. It used to be flared off, but auto ignition is unreliable, says John.
It has been another source of smells in the increasingly crowded Chapel Street neighbourhood. That particular problem will be solved by storing the methane for later use.
