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...

  Beside Rainwater Harvesting- and Utilization Systems, Greywater Recycling Systems  gain more and more importance. The AQUALOOP System  for example produces hygienic and clean water from from shower, tub and bathroom sink, which can be reused for flushing toilets, washing machine or irrigation. The potential saving by recycling greywater can be up to 40% of potable water in a domestic environment. The AQUALOOP is  not only saving  potable water, but also sewage, as water which normally will be discharged into the sewer system will be reused, therefore saving twice. Sample of an AQUALOOP system for a motel, hotel or apartment block. The modular system can be used for small domestic...

Water stewardship is an extremely important aspect of good environmental practice for hotels. Many use reduced flow and flush in bathrooms, but how many are recycling water? Water re-use is becoming core to many companies’ sustainability efforts and it’s never been more important.  Freshwater withdrawals have increased globally by about 1% per year since the 1980s (UN, 2016) and it is estimated that water scarcity now affects 40% of the global population (CAWMA, 2007).  Even in the UK some areas are reporting difficulties in meeting demand. Hotels often do a lot to manage water consumption. Low flow taps and showers...

Greywater Recycling. Sprawling cities gave way to the built up of waste, including dirty water. At first, cities were able to control the water going through the drains, but that is changing. Wastewater is a lot grittier and contains more contaminants than ever before. Water is still one of the earth’s most precious commodities, making it imperative that serious changes are implemented regarding how wastewater is treated. Recycling Greywater from Showers for secondary use is easy and safe with the right system.  www.aloaqua.co.nz Our system has a tertiary treatment, coarse filtration, biological treatment (aeration) and membrane filtration (0.2 micron).
