Effluent and wastewater stored in KlipTanks require efficient stirring to prevent the build-up of solids and crusts.

That’s why KlipTank has designed and patented our own stirring and aeration system, known as KlipJets.

With a unique design that utilises a pump to power multiple stirring nozzles and introduce oxygen through a venturi system, KlipJets offer superior performance and balanced aerobic treatment for your effluent and wastewater.

Why Aerate?

Aeration is crucial as it adds oxygen that aerobic bacteria thrive on. These bacteria help treat and balance the nutrients in the effluent, resulting in a more balanced and easily absorbed solution for the soil. Treated effluent, when properly aerated, is less likely to contaminate the environment or leach into waterways, promoting a healthier ecosystem.


Benefits of a KlipJet

  • Prevents settling –  KlipJets prevent solids from settling to the bottom of the tank, minimising the formation of sludge layers and floating crusts.
  • Promotes aerobic biodigestion – By introducing oxygen into the system, KlipJets promote ongoing aerobic biodigestion of the wastewater, accelerating its decomposition and reducing odours.
  • Reduced blockages –  Efficient stirring with KlipJets helps to minimise blockages when irrigating, resulting in smoother operation.
  • Odour reduction –  The balanced aerobic treatment achieved with KlipJets significantly reduces odours associated with effluent and wastewater.
  • Enhanced fertiliser – KlipJets increase the presence of nitrogen-transforming bacteria, leading to a higher availability of plant nutrients, including increased nitrogen levels.
  • Lower TSS and BOD –  KlipJets help reduce Total Suspended Solids (TSS) and Biological Oxygen Demand (BOD), improving the quality of the effluent and reducing its impact on the environment.
  • Easy to operate – KlipJets are safe and easy to operate. With no moving or electrical parts submerged in the tank, they require minimal maintenance.
  • Quick and efficient installation: Installing KlipJets is a breeze and can be completed in just a matter of hours. With no mechanical parts inside the tank, KlipJets experience fewer breakdowns and require less maintenance compared to traditional stirrers.
  • Proven results – Our New Zealand-made and patented aerator stirrer system has undergone independent testing, proving its superior performance in introducing oxygen and reducing odours. The homogenous slurry created by KlipJets ensures optimal irrigation effectiveness.

Frequently asked questions

Do I need a concrete pad for a KlipTank?

No, you don’t. Most of our tanks require a ground bearing of 30kPa unless we specify otherwise. Generally, you would scrape off the grass and topsoil and create a 60mm compacted layer of crusher dust or fines. Specific site preparation requirements may vary depending on the project.

Who can do my site preparation?

You have the option to do it yourself or hire a local contractor. We provide detailed instructions to make the process as easy as possible, and our Installation Manager is available for advice at any time.

Can a KlipTank be used on soft or unstable ground like Peat?

Absolutely. KlipTank specialises in these situations. Our tanks are engineered to withstand subsidence and movement. Please note that customers will need to sign a Waiver at the time of entering into an Agreement, acknowledging the need for extra monitoring and the possibility of additional costs for site preparation and maintenance.

Do we need to get a Building Consent for our KlipTank?

Yes, according to the NZ Building Code, any structure over 1.2m high or holding more than 35,000 litres requires a Building Consent. KlipTank will handle all the paperwork and lodge it on your behalf. We charge a small admin fee for this service and will pass on the Council’s charges at the end of your installation. This process ensures that a certified Engineer signs off on the tank design and conducts site-specific structural calculations for seismic, wind, and snow loadings.
