Commonly Asked Questions
WHAT GROUND TYPE CAN STORMVAULT BE INSTALLED UNDER?
The tanks have been designed for the majority of soil types and water table conditions in New Zealand. They are not reliant on surrounding soil structures for strength.
WHERE ON THE PROPERTY DO THEY GET INSTALLED?
stormVAULT tanks have been built to be easily installed under your lawn, but they can also be installed under a concrete drive if space is a premium on your site.
DO THE TANKS COME WITH A GUARANTEE?
stormVAULT stormwater tanks come with a 15-year domestic warranty. Devan has been in business for over 30 years and if there’s anything that time has taught us, it is that our customers see no compromise when it comes to confidence and reliability.
ARE THE TANKS COMPLIANT?
They sure are! stormVAULT has achieved compliance to AS/NZS1546 Septic Tank Standard, ARMA COP15 Underground Tank Code of Practice, and has been verified by CPEng Engineers here in New Zealand. The material is certified to AS/NZS4766:2006, AS/NZS4020:2005, and AS/NZS 2070
WHAT ARE THEY MADE OF?
The highest quality polyethylene available. Polyethylene cannot rot or corrode and is ultra violet stabilised. The manufacturing process produces zero waste and the product is 100% recyclable; it’s also ideally suited to our moulding technique, giving long life and trouble free service.
WHAT SIZES ARE AVAILABLE?
Each tank is manufactured to meet whatever your volume requirements are. Standard sizes are available in any combination from 2,000L to 10,000L with other volumes available on request. The more volume you require, the longer the tank. Larger volumes are achieved by coupling multiple tanks together onsite with ease.
