Our Processes

Kliptank has engaged Kirk Roberts Consulting Engineers for their design calculation and certification of the Kliptank product to meet NZ seismic & construction requirements.

Kliptanks are designed based on the following:

• The site must have an allowable foundation bearing pressure of minimum 30kPa (depending on the project 100kPa may be required)
• NZ Climatic & Seismic standards for wind, earthquake & rain
• Importance level 1 Structure as defined in AS/NZS1170.0:2004
• Structural design loads are based on a 25-year design life

Design has been made in accordance with the New Zealand Building Code Compliance documents:

• AS/NZS1170.0:2002 - Parts 1,2,3,4, & 5 (Structural design actions)
• NZS3404:1997 (Steel Structures Standard),
• NZS3101:2006 (Concrete Structures Standard),
• NZS3106:2009 (Design of concrete structures for the storage of liquids)
• AS/NZS1665:2004 (Welding of Aluminium Structures)
• AS/NZS1554.1:2014 (Structural Steel Welding)

Materials

• Walls - HDPE Panel with UV Inhibitors (thickness 4.5mm) with PVC extruded upright
• Top & Bottom Rings - Marine Grade Aluminium
• Wire Ropes - 8mm 19/1 Galvanised Wire Rope with Stainless Steel Swage Ends and Bronze Connecting Turnbuckles
• Liner - Potable Water Quality 1.0mm Flexible Polypropylene

Most Kliptanks require a simple base and do not need a concrete foundation.  Unless otherwise specified, a ground bearing of 30kPa is all that is required.  To put the ground bearing required into perspective, this is less than the pressure a bicycle or a woman wearing high heel shoes would put on the ground. 

The grass and top soil should be stripped back and a 60mm layer of crusher dust or similar material (with no sharp edges) used to prepare the site.  A wheelbarrow load of this material around the perimeter of the site every two metres should also be put down prior to installation so this material can be covered between the tank wall and liner by our install team.  Our general Site Preparation document can be downloaded from our Resources section. 

As site prep is one of the most important steps to a Kliptank installation, you should check with the Kliptank Install Manager or your Sales Engineer before your contractor starts work.

District Council requirements - Building Consent 

Every Council in NZ has a District Plan that includes Rules for each zoning.  Kliptank work closely with all the councils throughout New Zealand and understand their individual requirements.

We take the hard work away from you and will apply for a Building Consent on your behalf.  We know the quirky questions they want answers to and can complete the forms quickly.

Council has the right to request a foundation/location inspection and a final inspection.  Kliptank will co-ordinate these visits between the Purchaser and the Council.  Once the tank is completed and the final inspection has been passed, we will apply for the Code Compliance Certificate to ensure the Kliptank has met Local and Regional regulations.

Resource Consent

Depending on the Council, a Resource Consent may be necessary due to the rules outlined in the District Plan.

If this is the case, Kliptank can complete simple Resource Consent Applications but may advise you to deal directly with your local Resource Consent Management Services for more complex applications. 

A Building Consent normally takes 20 working days to process from the date it is lodged and accepted, however you would normally need to allow approximately 6 weeks for a Resource Consent.

The most important part of the tank installation is the preparation of the site. An inspection of your prepared site may be made prior to Kliptank sending out the install team to ensure it is the correct size, correct siting, level and ready to go. 

Hold ups cost money and should the install be delayed due to a poorly prepared site then a per hour labour rate is charged to rectify the site.

On completion of manufacturing, Kliptank will have your tank and liner transported to site ready for installation.  

Installation normally takes between 3-6 days on site depending on the size of the tank.

On completion of the installation, the Kliptank Sales Coordinator will contact the Council and organise a final inspection. A ‘Passed’ inspection is required to accompany the application for Code Compliance Certificate.

Maintenance 

Kliptanks require minimal maintenance.  We will provide you with a maintenance manual and list of regular checks to be undertaken once your installation is complete.

Kliptank can offer maintenance contracts to ensure hassle free, continued maintenance of your tank and fittings, pumping systems to the tank along with pipe work and pressure testing.  As part of a maintenance contract we will train any new staff on the operation of the Kliptank in your specific environment to ensure on-going performance of your system.  Speak to any Kliptank representative to chat further about this.

Warranty

Kliptank provides a 15-year conditional warranty on all our tanks and requires a two-year service interval. To ensure that your tank performs optimally, this service is mandatory for us to continuously offer the 15-year pro-rata warranty. If you are a current owner of a Kliptank tank, we will send you a service reminder every 2 years as part of our service commitment to you. The first service will occur one year after installation and will be complimentary. Should you choose not to register for a 2 yearly service and inspection plan, Kliptank reserves the right to reduce the standard warranty term to 5 years. Kliptank's warranty on supplied accessories is 1 year. 

Warranties on tanks installed outside NZ will vary - please ask for details.
