What is a tank made from?

Manufactured from polypropylene – a food grade plastic material which will not taint fresh water and will not allow odour absorption, making it ideal for waste/sewage water tanks.

 Do you want us to fit your tank?

We offer a fitting and plumbing service for all tanks at our premises 13 Wedgewood Street, Katikati.

Can I have it custom made?

Size and shape can be tailored to ensure all the available space is used.  Maximising the available space will allow you to be off grid for longer.

Will the tank fit my vehicle?

If you live nearby or are passing through Katikati, we are happy to put the vehicle up on the hoists to ascertain the best fit possible for your vehicle.

Can my vehicle become self contained?

Yes, Hercules Tanks offers you the opportunity to become self-contained whilst we manufacture and install your tanks.  A one stop shop.   Our self-containment officer is on site every day to carry out renewals of self-containment certificates.  Want to know more about self-containment regulations visit the New Zealand Motor Caravan Association.
