Uncovered KlipTanks are the reliable choice for your dairy effluent storage.

With over 500 installations, our tanks have proven their worth in managing on-farm dairy effluent.

Uncovered tanks also offer a versatile solution for a range of applications. Whether you need a washout bay for truck yards, a rainfall catchment system, or a fish farming setup, our tanks are up to the task. With their large surface areas, they provide ample space to meet your specific needs.

We understand the challenges of varying soil conditions. That’s why uncovered tanks can be installed on most soil types, including peat, high water table areas, and soft soils. No toroidal rings or concrete bases are required, making the installation process hassle-free and cost-effective.

Our team takes care of the Building Consent and/or Resource Consent process on your behalf, providing you with peace of mind and saving you valuable time and effort.

At KlipTank, we prioritise quality and compliance. Our uncovered tanks meet the rigorous standards outlined in the IPENZ Practice Note 21: Farm Dairy Effluent Pond Design and Construction. You can trust our tanks to deliver exceptional performance and adhere to industry best practices.

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.

What are KlipTanks made from?

KlipTanks are made from high-quality materials sourced from New Zealand.
