A Greywater Recycling Systems, like the AQUALOOP System for example, can produce hygienic and clean water from shower, tub and bathroom sink, which can be reused.
(image: BRANZ)
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.
The modular system can be used for small domestic dwellings and for commercial projects.
The AQUALOOP system has a NSF and BS certification, the only system that has achieved it so far.
It works with a tertiary treatment:
- coarse filtration
- aerated treatment
- membrane filtration (membrane life expectancy up to 10 years)
and eliminates 99.9999% of all bacteria and 99.7% of all viruses.

]]>We promote the reuse of Greywater for over 5 years now. Our system AQUALOOP has NSF and BS certification. Our system was consented and installed in AUCKLAND, CHRISTCHURCH, TAURANGA, QUEENSTOWN LAKES DISTRICT, TAUPO, INVERCARGILL etc and the treated greywater can be used for spray irrigation.
Potable Water from Rainwater System
Rainwater collected from the roof of the house is pre-filtered via a PURAIN filter and collected in a 10000 ltr tank. The integrated AQUALOOP water treatment system micro filtrates (0.2 micron) the rainwater and transfers it to a separate 500 ltr holding tank. The speed controlled RAINMASTER FAVORIT SC 20 pumping and control unit supplies the house with the micro filtrated rain water and maintains a pre-set pressure in the line. The unit will switch over to mains supply if not enough rainwater is available and back to rainwater if it has rained again, all by itself. Thus only using the mains water supply that is required. No tank top up!
All the potable water supply, regardless if it is filtered rain- or mains water is treated with a UV system, thus eliminating any bacteria or viruses that could enter via the mains supply.
Greywater Recycling System
The bathroom greywater is pre-filtered and collected in a 500 ltr tank. The integrated AQUALOOP System is treating the greywater, breaking down organic compounds, micro filtrates (0.2 microns) the water and transfers it to a seperate 500 ltr holding tank.
A RAINMASTER ECO 10, pumping and control unit, supplies toilets, the washing machine and an outdoor tap with recycled bathroom greywater, thus saving up to 40% on potable water.
This AQUALOOP system is the one of many greywater system in Christchurch , Auckland, Queenstown, Tauranga etc, etc. the only NSF/ANSI 350 Class C certified system on the market.
Membranes have a life expectancy of up to 10 years with minimum maintenance requirements. The system was also tested by the Rainwater Harvesting Centre at Massey University Wellington. It is modular and can be sized from small domestic up to big commercial applications (life style, hotels, motels, camping grounds, swimming centers, laundries, office blocks, gyms etc, etc.).
INTEWA CEO and owner Oliver Ringelstein and Bob Drew from Ecovie, the exclusive INTEWA representative for the USA, led a whirlwind trip from Alaska to Los Angeles. The first stop was at a laundromat in Alaska. Here AQUALOOP technology allows for the reuse of the laundromat wastewater together with shower water. Even though in Alaska there is water everywhere the prices in this location are particularly high. Lack of supply and quality problems exist with the available water. AQUALOOP technology allows the operator to have the best water quality and a fast system amortization.

The next stops on the west coast trip included Seattle, Portland, San Francisco and Los Angeles. Due to the continual droughts in this area greywater recycling, rainwater harvesting, and wastewater reuse are themes of increasing importance. With the only NSF/ANSI 350 Class C certification INTEWA systems meet the stringent requirements for the region.
The greywater system installed at the famous Eatalyin Los Angeles was showcased in an earlier newsletter, but the system is so interesting that we would like to show it off again. The system is special in that it is presented in a large, descriptive showcase in the middle of the luxury foodie complex.
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. It switches over to mains water if not enough treated water is available without any loss of comfort for the home owner.
A rainwater harvesting system, also part of the renovation, filters and collects the run-off from the roof in an in-ground rainwater tank.
A pumping unit and UV system will be used to supply the treated water to the house.

Using rainwater for flushing toilets and washing machines is maybe something new in New Zealand, but is already standard in most European and other countries. Solutions using rainwater for various applications offer new possibilities for property owners, developers and councils.
Rainwater is of such good quality that it can be used as potable water, with the right technology. No bacteria, nitrate and chemicals and instead soft water which causes no calcification in pipes, hot water cylinders and on surfaces.
Mitigating the effect of storm water run off from properties, by retaining and using it on site, reducing the volume of potable water use and offering new areas of work for installers.
Examples of rainwater harvesting and utilization systems: www.aloaqua.co.nz
One manufacturer of rainwater harvesting and greywater recycling equipment in Germany has started to brew it's own beer from rainwater (Brain - http://www.brainwaterbeer.com/) to showcase how good it taste (I had a bottle and it taste really nice).
Rainwater attenuation, - retention
The increase of sealed surfaces in urban areas put additional pressure on the existing stormwater infrastructure. More and more councils require now rainwater attenuation/ retention systems to be installed for new developments. Innovative systems that are cost effective, space saving and require low maintenance are already used in densely populated areas in Europe. More information: Rainwater attenuation/ retention

The installation of a combined Greywater Recycling and Rainwater Harvesting system from ALOAQUA will save on potable water and sewage. In addition the rainwater tank helps to minimize the impact of the property on surface flooding. Greywater is available everyday and it makes perfect sense to capture, treat and reuse it for secondary use (toilets, irrigation, cleaning).
Greywater collected from the bathrooms (sink, tub, shower) is collected and treated in a 500 ltr tank via the AQUALOOP system. The tertiary treatment (pre-filtration, aeration and membrane filtration) eliminates all coarse particles, bacteria (99.9999%) and virus (99.7%). The treatment process is monitored and controlled via the AQUALOOP controller which initiates each step of the process.
The treated water is filtered through the membrane (0.2micons) and transferred into the rainwater tank after the required treatment time. The membrane is back-flushed in regular intervals in order to open up any clogged openings. The expected lifecycle of the membrane is 10 years.
.
The Rainwater collected from the roof is filtered via the PURAIN filter and added to the tank (5000 ltr) via the calmed inlet from the PLURAFIT range.
The pumping and control unit RAINMASTER FAVORIT SC20 ensures a steady and reliable water flow to the points of use (toilet and outdoor taps). The unit switches over, by itself, to mains water supply if the water level in the tank reaches a critical low level and back again if the water level rises again. No interruption to the clients at all!
A great system that will significantly lower the ecological footprint of this property but will also enable the owners to have water available during restrictions, drought or in emergency situations.

Capturing rainwater and reusing (treated) greywater will save the owner not only potable water and sewage charges but is also better for the plants they intend to water with it. Benefits for the council are less stress on their infrastructure (storm water, potable water and sewage), less maintenance and less expenses.

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 or aerators, reduced flush toilets or no flush urinals, sensor activation and good housekeeping practices all help to reduce the amount of water per guest, per room and per stay. But, even with these measures many guests admit to using much water during a hotel stay than they would at home, and in some water scarce areas, the difference in consumption between a hotel guest and the local population can be up to 20 times and dozens of litres.
Anything hotels can do to better manage their water consumption is a good thing, but how many look at recycling water?
Significant water consumption savings can be made from re-use initiatives. Rainwater harvesting can reduce mains water consumption by up to 30% whereas greywater recycling can save as much as 40%. Aside from lower metered water bills, companies can also benefit from reduced risks of storm water flooding, decreased sewerage charges and lower energy costs associated with water supply.
Last month on World Water Day Waterscan unveiled its next generation range of greywater recycling and rainwater harvesting technologies. The new water re-use solutions offer commercial organisations a variety of cost-efficient, reliable and highly effective options to help achieve their sustainability goals.
Claire Yeates, a Director at Waterscan said: “Many companies are aware of the benefits of water re-use but are naturally concerned about payback times and the potential operational impacts of installing new technologies. Add to this reliability issues from early-to-market systems and it’s easy to see why widescale uptake of water recycling has been hindered. We firmly believe that greywater recycling and rainwater harvesting can play a significant role in many company’s water strategies and that is why we are bringing new best-in-class technology to market.”
The various water recycling systems have been developed to give greater system design flexibility in line with customer priorities and requirements, plus a 30% faster return on investment. Waterscan systems now feature:
- Multiple tiered redundancy to ensure complete integrity of supply.
- Built-in telemetry which transmits system data and live diagnostics for preventative maintenance.
- Siemens smart user interface for usage data and enhanced system monitoring.
- Variable speed, load sharing pumps, insulation and slow close valves for an even quieter operation.
- Low energy components so the system can produce 1m3 using just 1.5Kw/h energy.
- A smaller system footprint which reduces installation costs and impact on building footprint.
Barry Millar, Operations Director at Waterscan, said, “Our new water re-use systems are now designed and largely built in the UK using modular components. This enables us to meet clients’ exact specifications in line with individual business strategies and site requirements. Our complete service involving design, supply installation and maintenance of water-saving systems, along with our consultative approach, gives us a unique ability to deliver optimum results across varied client property portfolios. All of this means that our clients will benefit from a faster return on investment and still have complete confidence in their operations.”
Greywater Recycling in Action at Premier Inn
In partnership with its client Premier Inn, Waterscan installed a greywater recycling system in water-scarce Abu Dhabi. The initiative is vastly reducing mains water consumption, saving an average of 735,000 litres (24%) of mains water each month - 60 litres per guest. Over the course of a year, this is the equivalent of 110,000 baths. 100% of toilet flushing at the hotel now uses recycled water.
Greywater Recycling
Greywater recycling captures the water used for showering or bathing and, after treatment through an ultra-filtration membrane system, is fed back into the property for non-potable purposes such as flushing toilets, irrigation and laundry.
- Greywater Recycling Batch System: where low energy consumption is a priority and there is physical space for a larger system footprint, this low pressure filtration method takes a little longer but uses less energy in the process.
- Greywater Recycling On-Demand System: where space saving and a faster return on investment are priorities, this high pressure approach delivers rapid ultrafiltration and therefore requires less tank storage and correspondingly reduced installation costs.
Rainwater Harvesting
Rainwater is collected, filtered and fed back into the property through a robust treatment system ensuring that only the cleanest water is utilised for non-potable purposes like vehicle washing, toilet flushing and irrigation. A rainwater harvesting system is suitable for all commercial applications where there is adequate roof space to harvest sufficient water to achieve a good return on investment.

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).
Water is the basis for the entire biosphere. Ponds, rivers, lakes, wetlands, and oceans are the habitat for myriad plants and animals and are a key component of the ecosystem. Groundwater is one of our main source of drinking water and a habitat. We use water for our food, daily hygiene, and recreational activities. Water also plays a key economic role as an energy source, transportation medium and raw material.
Efficient protection and conservation of water resources are crucially important for biodiversity and sustainable use.

Another AQUALOOP combined Greywater Recycling and Rainwater Harvesting System in Christchurch pretty soon.
"Quakes reinforce need for emergency water supplies" MASSEY UNIVERSITY
Water shortage is now a major problem in the quake-affected towns along the Kaikoura coast, and while a small rainwater tank will provide drinking-water needs only, a larger harvesting and treatment rainwater tank could easily provide all of a households needs during an earthquake or other natural disaster.
The first truck to make it into Kaikoura after the 7.8M earthquake that struck on the 13th of November was a water-truck! Now making round-the-clock trips to replenish the town's water supply from the Kaikoura reservoir, which has been restored with only a very limited supply.
This should be a wake-up call for people in town centres who have become overly reliant on reticulated water supplies, who live on or near fault-lines, or who are facing contamination issues due to poor maintenance / pollution. Water is an absolute priority, and it is up to each household to ensure they are water secure.
It is easy to install and operate a safe rainwater utilisation system. While Dr. Stan About from the Roof Water Harvesting Centre notes that contamination can be a problem, we have reliable solutions to deal with this - without resorting to chemicals. Our organic membrane-filtration rainwater treatment system provides one of the safest bacteria-free solutions for rainwater harvesting and general water utilisation throughout your whole home.
Be resilient and self-sufficient! Have your own safe water supply.
Have you ever wondered whether or not it's safe to drink rain water? The short answer is: Yes!
Here's a look at when it's not safe to drink rain water, and what you can do to make it safer for human consumption.
When You Shouldn't Drink Rain Water
Rain passes through the atmosphere before falling to the ground, so it can pick up any contaminants in the air. Now most of NZ is pretty safe in regards to contaminants, but it's not a great idea to drink rain water falling near chemical plants or near the plumes of power plants, paper mills, etc.
Rain Water That Is Safe for Drinking
Most rain water is safe to drink. Actually, rain water is the water supply for much of the world's population and around 15 - 20% of New Zealander are relying on it.
The levels of pollution, pollen, mold, and other contaminants are low -- possibly lower than your public drinking water supply. Keep in mind, rain does pick up low levels of bacteria as well as dust and occasional insect parts, so you may want to treat rain water before drinking it.
Making Rain Water Safe
Roof
If you intend to build, select a roofing and gutter material that is neutral, non toxic and easy to clean. If you have an existing roof have a look at it and your gutter, a painted roof could leach out toxic components, asbestos is a no go. More info regarding roofs available from the following website: http://www.level.org.nz/water/water-supply/mains-or-rainwater/harvesting-rainwater/
Filtration and Water Treatment
We recommend to pre-filter the rainwater before it enters the tank. Leaves and coarse particles will be hold back, thus minimizing the build-up of sediment on the bottom of the tank. A calmed inlet to avoid that the incoming rainwater is disturbing the sediment is also a must.
PURAIN PR100 Rainwater Filter
A ultra filtration system treats the water further and ensures that the treated rainwater is safe for consumption.
AQUALOOP Water Treatment System
Eliminates 99.9999% of all bacteria and 99.7 of all viruses, 0.2 micron filter (0.0002mm), life expectancy 10 years.
The AQUALOOP System was tested by Rainwater Harvesting Centre at Massey University in Wellington. No e-coli and coliform passed the filter even with high amounts of them.
In general is it easy to make your rainwater potable, we have the right knowledge and gear for it. Having a system like this ensures that you have a water supply that is without chemicals, bacteria and available in emergency situations.
