Rain Harvesting;- Collection, Filtration & Storage

As you have previously read, after finding out how much water is used in a typical house in winter by just 3 appliances, we knew we had to start collecting and reticulating rain water off our Auckland roof to use in the house!

When I was building stage 1 of the house back in ~2005, I had to import first divert units that integrate into your down-pipes from Australia - as they already knew how valuable rain water is - and how much a pest the mossie is! Thankfully, in 2009, Marley NZ have now partnered with the Australian group and have adapted / improved in some cases the Australian range of products :-)

We then had to find a company to supply a water tank that could be buried, would last a long time, AND the water would taste nice! To learn more about Why We Used A Concrete Tank, please click here. We found Warkworth Tanks were extremely helpful and also made high quality concrete tanks!

Collection Surface - i.e. our roof

Collection Gutters: We used Marley NZ's Magnum range - big, chunky and collects ANY water coming off our roof :-)

Gutter Protection: This could be a Leaf Guard product or similar. We don't need it here at our place as no tree is higher than our 2nd storey roof...

Rain Head Inlet Filter: We used Marley NZ's clever product where it has two mechanisms to stop mossies, leaves, mice, birds etc getting down into the tanks

First-flush Diverter

Inlet Screen

Collection Cistern

Overflow Port: We used Marley NZ's vaccum kit +

Auto-fill / Automatic Top-up Mechanism: We used Davey Pump's RainBank MkII way cool device!
