Flexible rainwater bladder-tanks stay out of sight in Bondi renovation
Rainwater bladders - a new design of water tank that are flexible enough to fit
under the house - are proving increasingly popular with renovators.
A traditional water tank will only capture water from one side of the roof,
whereas a bladder installed under the house uses the entire catchment surface
area of the roof. This means up to 500% more water is captured compared to the
standard tank system.
The system, called Rain Reviva, was ideal for Bondi resident Mr Stephen Hain who
has installed two Rain Reviva bladder-tanks which can hold a total of 9,000
litres of rain water.
“When we rebuilt our home we saw an opportunity to put in the rain water
harvesting system. We didn’t have a lot of space around our home – and a lot of
the tanks are really ugly. We went with the bladder-tanks because they are so
easy to install and can hide away under the house,” Mr Hain said.
“I think it’s a fantastic idea and so many houses like mine that have unused
space under their home could accommodate these tanks. They only need a metre of
height. The local council required us to install the rainwater recycling system,
but we feel strongly about the environment, so we saw it as a good opportunity.
“The tanks were easy to install – I followed the instructions for assembling the
bags. Then a plumber came and fitted the pipes to our automatic sprinkler
systems in the garden. We enjoy our garden, so this system is perfect during the
current water restrictions,” he said.
Andrew Pearce, CEO of New Water, the suppliers of Rain Reviva tanks, believes
they work far more effectively than the traditional tank, which is not able to
capture water in the same way and typically takes much longer to fill.
“As of July this year, all residential alterations and additions throughout NSW
must meet Building Sustainability Index System (BASIX) requirements for
rainwater harvesting. By installing Rain Reviva bladder-tanks, homeowners will
comply with BASIX,” Mr Pearce said.
“In fact, up to 30,000 litres of water can be stored underneath a house using
our tanking system, which can make a considerable difference to a household’s
tap-water usage,” he said.
“Homeowners need to think seriously about how rainwater tanks can make a real
difference, and we believe this is the best way to harness rainwater and store
the water. The fact that the tanks stay out of site is an obvious bonus.”
In addition to the bladder-like tanks, the patented system incorporates an
‘inlet diversion’ – a ‘swing arm’ system - that efficiently diverts the
rainwater from each downpipe into the bladders and when they are full, ensures
the excess water reverts back to the stormwater outlet. A pump system then
allows the water to be reticulated to a range of devices such as the garden
hose, the pool, sprinkling systems and even the washing machine and dishwasher.
The Rain Reviva bladder-tanks come in a range of sizes, which can be linked for
extra capacity. Prices typically start at around $2,000 to $2,500 for a bladder
of up to 4,000 litres.
New Water sells the Rain Reviva system throughout the country. The system is
sold as a full kit, which includes a pump and pressure control mechanism.
The company is also in the process of launching a system that recycles household
