Frequently Asked Questions

Tank ​Installation

Q: What kind of ground preparation is involved?

A: The installation of our flexible tanks requires a perfectly flat and horizontal surface with the empty dimensions of the tank + 2m in length and width.

A compacted bed is recommended to ensure a stable platform. A top coat of rolled sand ~10cm thick is then required. Full instructions are sent out with each tank.

Q: How do I work out what size I need?

A: This all depends on what type of liquid you are looking to store. Whether it’s effluent, water, domestic or industrial we are here to help you. Get in touch

Q: How long does it take to get up and running?

A: Once you have the tank you can be up and running in a matter of hours. 

Q: What kind of maintenance is involved with my Flexi Tank?

A: The maintenance obligations depend on the liquid stored. As such, the tank doesn't require any special maintenance.

Q: Do I need a consent?

A: Please check with your local council, local regions may differ and rules can change frequently.

Product Questions

Q: How strong are Flexi Tanks? Do they burst?

A: Our tanks are the highest quality and strongest sold in New Zealand. They are built by a longstanding French Manufacturer established in 1959. Made from a multi layered technical rip-stop fabric with a tensile strength of 450kg per 5cm. 

Not all bladder tanks are built the same. At Flexi Tanks we sell only the top of the line tanks, because of this in our 7 years of installing across New Zealand we have not had any issues with our tanks bursting. 

Q: What sizes of tanks do you offer?

A: Our Flexi Tanks can store from 1,000 litres to 2,000,000 litres of liquid matter. We have wide range of sizes to solve your liquid storage needs.

Q: Do you do custom sizes?

A: We do offer custom sizes. To discuss your options please get in touch

Q: Are Flexi Tanks depreciable? 

A: Yes, they are depreciable as they are a tangible asset that can be rolled up and used on your future projects.

Q: How long do Flexi Tanks last for?

A: We offer a full 10 year manufacturer's warranty for textile and manufacture. Expected life under normal conditions is up to 20 years.

Q: What kinds of liquids can be stored in my Flexi Tank?

A: Different tanks specialise in different liquids. We have tanks for potable and non-potable water, effluent, liquid fertilisers, leachates, grape marc, hydro-carbons, and more. Any liquids between a 4-10 pH factor. 

Q: What kinds of valves and pipes do I need and where can I get them?

A: All our tanks come with the necessary valves and male camlock ready for you to connect onto with 3m of your flexible line.

Q: How much do Flexi Tanks cost?

It varies according to the volume of the tank and the materials chosen to make it. We are here to provide you with the best, most cost effective solution depending on the nature of your project. 

Q: When storing water what is the water quality like?

A: Because there is no light or air inside of the bladder tank water stays as fresh as the day it enters. Growers are amazed at how good the water quality is and the positive effect it is having on their production. 

Q: Are there compartments, or baffles inside the tank?

A: No, they are self-supporting. When they are empty they lay flat.
