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!

On the RHS is the rain water inlet into the concrete water tank, via 'Marley Calmed Inlet'. This stops the rain water from stirring up any sediment that may build up over time in the bottom of the tank (especially if you haven't used 'Marley First Divert' systems on your down-pipes).
