Greywater Recycling in Auckland

The renovation of an old villa in Devonport / Auckland was the perfect opportunity to upgrade the plumbing- and storm water system. Tony Koia from Koia Architects Ltd  decided to go a step further and future proof the house with a rainwater harvesting and a greywater recycling system from ALOAQUA Ltd.  Bathroom greywater (bath, tub and sink) will be collected in a tank, treated with the AQUALOOP system and reused for flushing toilets, the washing machine and irrigation. Thus saving between 30-40% of potable water and sewage. The RAINMASTER ECO 10 pumping and control unit supplies the treated water to the end users....

Water management in commercial buildings - thinking differently.

Water management in commercial buildings - thinking differently.

As the world's population continues to grow and our cities and suburbs expand, with more buildings to accommodate the growth, we are facing a major challenge to manage and protect our valuable water resources. This is becoming especially critical under the added pressure of climate change. The conventional and common approach to water management involves supplying potable water and disposing of waste - and stormwater. It is becoming increasingly apparent that this conventional, centralized approach must change in response to urbanization trends and climate predictions. As the availability of clean freshwater resources is diminished, it is becoming clear that in particular grey- and stormwater...
