Jack’s Point Queenstown
By Innoflow
Iconic Queenstown subdivision Jack’s Point has resource consent for 1400 lots, although 900 homes were proposed initially. The development is handily located to a municipal wastewater treatment plant, but a decentralised wastewater management system was chosen for capacity and cost benefits.
The Otago Regional Council adopted an effects-based approach to land treatment, requiring levels of post-development nutrient load to be less than levels measured pre-development. The authority granted a resource consent to discharge up to 1,374,000 litres a day to land.
Innoflow demonstrated that their technology would meet strict nitrogen level requirements, which was backed up by their OSET trial data. Additionally, the liquid only sewer system meant the cost of primary treatment was deferred to the homeowners, risk of stormwater infiltration was significantly reduced, and maintenance costs would be much lower than a comparable gravity sewer.
The installed system comprises small diameter effluent sewer for wastewater collection, on-lot Step/Prelos tanks and the AdvanTex® Recirculating Textile Packed Bed Reactor for the treatment system. Innoflow also supplied and installed the land treatment system by way of subsurface drip irrigation.
System Performance
The wastewater treatment system produces high quality effluent with the following outputs:
- Biochemical Oxygen Demand (cBOD5) levels averaging 15mg/L
- Total Suspended Solids (TSS) levels averaging 20mg/L
- Total Nitrogen (TN) levels averaging 15mg/L (New Limit)
- Total Phosphorus (TP) levels averaging 12mg/L
- Escherichia-coli (E.coli) levels averaging 10,000 cfu/100mLs
Treated effluent is disposed of sustainably, and the low-profile, below-ground wastewater treatment plant design is barely noticeable on the landscape.
The whole of life cost for the entire system, along with the ability to easily expand the plant in the future as the development grows, meant the Innoflow solution made economic sense to the developer, as well as environmental sense.

Other Applications
No matter what your application is, Innoflow can point you in the right direction as one of the big advantages of our technology is it's versatility.
AdvanTex systems have been installed in every situation imaginable including mining camps, power stations, immigration centers, remote offshore islands, and even in the world’s first commercial spaceport.
Tourism
New Zealand’s distinctive natural landscapes are an integral part of our national identity and are at the heart of the tourism industry. Careful effluent management at tourist sites is essential not only to minimise environmental impacts but also to protect tourists’ health.
Additionally, the quality of a destination’s infrastructure is a key part of its tourism offering, particularly in relation to the visitor experience. Wastewater treatment facilities must provide reliable and cost-effective treatment despite widely fluctuating flows.
From cycle trails to bungy jumping, some of New Zealand’s favourite tourist experiences take place in remote and rugged locations. These sites often present further challenges for effective wastewater treatment, such as extreme temperatures, high water tables and poor soils.
Hundreds of AdvanTex systems are installed in parks, campgrounds, resorts, and lodges that experience highly variable flows (or complete shutdowns for long periods) due to seasonal use. Shortly after the system is placed in service or on commencement after periods of no use, a bacterial film starts to develop in the upper portion of the textile media; allowing the removal and breakdown of solid matter and organic material to start within the first 24 hours.
In isolated areas with limited local technical support, systems may need to run on solar power and must be low-maintenance and hassle free.
For many years, Orenco’s AdvanTex® technology has provided a reliable, energy-efficient alternative for wastewater treatment in some of the world’s most remote places.
