To help prevent drainage infrastructure from being overwhelmed, local councils often require stormwater attenuation tanks as part of building consents – and that’s when stormVAULT stormwater tanks come into their own.
On undeveloped land, a large proportion of rain soaks into the ground and flows slowly through the upper soil layers or into streams. But housing and commercial development results in increased hard surfaces such as driveways and buildings, which have negative effects on stormwater – less water can soak into the ground, there are increased flows of water into streams, and flooding becomes more common due to the speed with which extra water reaches pipes and waterways.
stormVAULT tanks are the perfect solution to prevent overflow, storing excess stormwater below ground and slowly releasing it into council stormwater systems. Whether for beachfront or hillside, stormVAULT tanks have been designed and tested for the majority of soil types and water table conditions in New Zealand and are not reliant on surrounding soil structures for strength. They can be installed under lawn or concrete and are unobtrusive, with the only visible part of the tank being the child resistant inspection lid.
They’re also incredibly tough! stormVAULT is the thickest, strongest, and heaviest product on the market. The demands put on products that go underground are high, so stormVAULT has been built from the highest quality polyethylene available, to exceed design standards. Polyethylene doesn’t rot or corrode and is ultra violet stabilised, plus the manufacturing process produces zero waste and the product is 100% recyclable.
stormVAULT tanks come in standard sizes from 2,000L to 10,000, with other volumes available on request. They come with a 15-year domestic warranty, meaning they’re an easy, trouble-free solution to managing stormwater on your site or property.
