Whilst much of New Zealand has been spared a totally torrid summer thanks to recent rain, conditions are still dry out there, particularly in the east. With the threat of water restrictions still looming for late summer, many are considering rain water harvesting to help with both potable and domestic irrigation water supplies.
RX Plastics Water Tanks
RX Plastics are able to meet this demand in lifestyle and rural situations with its range of MAX™ Tanks but in smaller domestic applications the Metro range of tanks offer a compact yet capacious solution.
Holding up to 5010L in a triple tank set up (comprising a Single 1670 Litre and Double Tank of 3340 Litres) the modular system provides valuable backup storage that can be used for most domestic purposes
Designed to be neighbourhood friendly
Tanks don’t have to be so huge that they’ll upset the neighbours! RX Metro tanks have been designed with urban rainwater harvesting in mind; their slim upright profile means a small footprint and their ability to be arrange in a linear or corner configuration makes them suitable for all properties, large and small.
Available in 11 shades, they’re also easy to incorporate into most exterior colour schemes that are suitable for even the strictest of subdivisions!
Easy to install
Metro Tanks can be installed by a plumber or a roofing contractor in less than a day and use standard pipe fittings. All that’s required is a level platform for siting and capability for any overflow from the tanks to be dispersed away from the tanks’ foundations.
If used for non-potable supply for such applications as toilet flushing, laundry or garden watering, rainwater doesn’t require any further treatment. If you’re looking at your reserve as a drinking water supply then it’s recommended that rainwater be treated to counter any pathogens that may be collected from roof run off.
Pure and fresh drinking water
If you’re going to use your harvested rainwater for drinking it’s also recommended that all potable systems install a ‘first-flush diverter’ – a device which ensures that the first rainfall on the roof is disposed of rather than added to the tank. This ensures that undesirable objects like dirt and dust, leaf litter, bird and pest excrement and other nasties don’t make their way into your drinking water.
Once the larger undesirable elements are diverted, your rainwater will require further treatment to exclude any microbial pathogens, such as e-coli, will need to be dealt with. UV treatment is the most common method, but other options such as reverse osmosis and ceramic filters may also be suitable. Talk to your plumber to ascertain which is best for you.
RX Metro Tanks are manufactured from high quality food grade virgin polyethylene, UV stabilised to protect it from breaking down in sunlight to ensure that your treated water stays fresh for use.
Rainwater harvesting is not only a wise use of a valuable resource, but can also give a homeowner a sense of self-sufficiency. If for any reason there’s an interruption in a reticulated supply, having your own water supply can be a godsend. When you’re living in the ‘Shaky Isles’ in a time of somewhat unpredictable climate this peace of mind cannot be underestimated.
