Solution for Waipukurau Wastewater Treatment Plant a Must

To be released 27 September 2017   MED201733

Efforts to reduce the odour issue from the Waipukurau Wastewater Treatment plant have only been partly effective and more work needs to be done.

Central Hawke’s Bay District Council Chief Executive Monique Davidson acknowledges that the smell is offensive and unacceptable for properties in the neighbourhood.

“Council Officers are working hard to resolve the problem. Our initial efforts have partially worked. Now we have identified the need for further aeration and have purchased additional equipment,” says Mrs Davidson.

Chief Executive, Monique Davidson says initially the smell was due to high hydrogen sulphide levels coming to the surface of the new stormwater balancing pond from the outflow of the anaerobic pond.

“We applied a top dressing solution of sodium nitrate, and this has been partly effective at reducing the odour. Despite this, some smells are still being emitted from the anaerobic pond, so we have closed it down until a permanent solution is installed.”

The additional aeration units are being installed this week. What the additional aeration units won’t fix is the current ammonium levels that the Wastewater Treatment Plant is having, which are higher than the consented allowances. This is a concern to the Council.

At a Council meeting last week, Mayor Alex Walker moved a motion which was quickly seconded by Councillor Gerard Minehan.

That a report on the appropriateness of the Waipukurau and Waipawa wastewater treatment systems and their ability to meet current resource consent requirements is presented to the Finance and Planning Committee by the end of November. The motion also included that the scope needed to include all resource consent requirements for both systems, the capacity of the system to deal with current residential and trade waste demands, as well as future growth projections for the District.

The motion was supported unanimously by Council.

Speaking to the motion, Mayor Walker highlighted that “The Community and Council have been very patient on this long standing issue, we need all the information in front of us to give us the outstanding questions and potential solutions – the current situation is not acceptable. ”

Chief Executive Monique Davidson speaking to the motion advised Council that the scope requested is what would be delivered. “We are collating information from all parties involved to-date with the expectation of formulating some long term recommendations by mid November – at which stage we are absolutely committed to a public meeting with the community. We want to be confident that when we go back to the community we have thought of everything, and are focussed on a long term solution, not just a band aid fix.”
