Water treatment paper wins gold

Congratulations to Iain Rabbitts and Nicola Smallberger for winning the Hynds Gold Award for Best Paper of the Year at the Water New Zealand annual conference in October.

Iain and Nicola’s joint paper was about our work on the $10 million upgrade to the 70-year-old Kerepehi water treatment plant water for the Hauraki District Council. Iain was the technical manager and designer of the upgrade, which has increased capacity by more than 30% to deliver 12.5M litres of treated water per day to the region.  

The paper and Iain’s presentation were marked by Sarah Lothman from BTO Cardno and Louis du Preez from Hutt Valley Water Services. Their comments were read out at the conference dinner, where Iain accepted the award:  

This well presented paper set out the options and design path followed to upgrade Kerepehi - a medium size plant drawing water from the Waihou River. The raw water reached very high turbidities during high tides which presented particular challenges to Treatment. This 1960’s plant was upgraded to provide twice the output flow and meet the new Drinking Water Standards utilising most of the existing concrete structures on site. The presentation was well delivered with confidence, humour and clarity. Questions were properly answered.  

Iain said it was fantastic to have Harrison Grierson’s work on the Kerepehi plant acknowledged at the Water New Zealand Conference where delegates appreciated and understood both the technical challenges of the project and its implications for the region.  

HG Wins Mount Isa Stages 2 & 3  

Congratulations also to Colin Cranfield and his team. We’ve been commissioned by the Mount Isa City Council, in North West Queensland to undertake design work on Stages 2 and 3 of the $27 million upgrade to the sewerage scheme for the city (population 25,000).  

This work follows our successful completion of Stage 1, which was an upgrade to the sewage pumping stations and the large diameter trunk sewers and sewer rising mains through the city, which will be used to convey sewage from the residential and industrial growth areas through to the treatment plant.  

Stage 2 is the upgrade to the sewage treatment plant to increase the treatment capacity from an equivalent population of 25,000 to 33,000 and to improve the treated effluent quality to grade A+, which is defined as safe to irrigation in public spaces. Stage 3 is the design of expanded irrigation areas and/or treated effluent pipelines to the Mount Isa mines for use in dust suppression around the open cast mine site.  

In January 2011, Harrison Grierson was commissioned on the design of the Stage 1 works, after a very competitive tender process.  Colin says that during the last two months, the design of the Stage 2 and 3 works was directly negotiated between the Council and Harrison Grierson, based on our project knowledge and the high level of service we provided during Stage 

IPENZ Award for Excellence  

Our design work on the Martin Wilson Reserve Stormwater Upgrade in Auckland has contributed to the project winning the IPENZ award for excellence in environmental practice.  

The Martyn Wilson Reserve Stormwater upgrade was an Auckland Council $1.5 million project that turned an underutilised area of degraded wetland by Hobson Bay into an attractive area with timber walkways and native plantings set around a stormwater treatment pond. 

The stormwater upgrade was designed by us, project managed by BECA, constructed by HEB Construction Ltd, with Andrew Stewart Ltd as the environmental and consenting consultants.  

“Auckland Council and its project partners used innovative construction techniques as well as a team based approach to resolving the project’s numerous engineering challenges”, says Auckland Council’s manager of Infrastructure and Environmental Services, John Dragicevich.
