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.
Drinking water from rainwater RAINMASTER DUPLEX
with AQUALOOP ultrafiltration pumping and control unit
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.

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.

By collecting rainwater we have a direct positive impact on the environment that all can see. Rainwater collection obviously reduces municipal water use, but how does this help the environment? Do you know that the average household is using 18% of their water for flushing the toilet? And 23% for the washing machine!
1. Rainwater Harvesting and Utilization (Click Here) is an alternative, and in many cases a better, water supply to the normal surface water based supplies from reservoirs or groundwater based supplies from wells tapped into underground aquifers.
2. Rainwater harvesting (Click Here) helps manage stormwater run-off to prevent erosion, flooding and poor water quality in our lakes an streams.
- Rainwater can have a major impact on water supply and has been shown to be able to reduce municipal water demand enough that large new public water sourcing projects become unnecessary.
- In urban settings, up to 90% of water runs off because of sealed surfaces like roads, parking lots and roofs. In nature, up to 90% soaks into the ground. Rainwater harvesting systems counteract stormwater run off and thereby reduce flooding, erosion and ground water contamination. When combined with an infiltration system like rain gardens or an in-ground system (Click Here).
- Taking water out of our lakes, reservoirs and rives effects groundwater, irrigating with rainwater helps replenish groundwater supplies.
- Infrastructure projects to increase water supply use massive amounts of energy and natural resources in addition to the obvious cost to ratepayers. Rainwater harvesting and utilization helps minimize the need for these projects.
- Municipal water treatment and pumping make up a high percentage of energy and chemicals. Rainwater systems reduce this usage.

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 should be viewed as alternative and valuable sources of water, and not just inconveniences needing to be dealt with.
Consequently, rainwater collection and reuse and the reuse of highly treated greywater are attracting increased attention. They are most-commonly provided for non potable end uses but potable reuse is also gaining traction.
Many communities have begun to implement simple and relatively inexpensive water-reuse projects, such as irrigating golf courses and parks, and the benefits of these are seen almost immediately. Benefits from widespread adoption include improved reliability and drought resistance of the water supply, utility savings in infrastructure maintenance and deferred capital expenses, and the immediate rewards of green and lush outdoor recreation spaces.
There are also environmental advantages to consider. The use of reclaimed water ensures the transfer of nutrients to beneficial uses rather than discharging them into receiving waterways. Contamination of bays and lakes with nutrient-rich stormwater and wastewater increases the risk of eutrophication (excessively high nutrient concentrations), the consequences of which include low dissolved oxygen concentrations, algal blooms, and declining shellfish populations and periodic fish kills.
Increased and more widespread use of reclaimed water typically brings with it greater financial, technical, and institutional challenges. Upfront capital costs may be higher, but payback on these water-reclamation systems may be realized sooner by building owners, depending on the region. Regulators and citizens express concerns about the safety of using reclaimed water for domestic purposes because of the perceived risks and uncertainties. These challenges have limited the application of water reuse in the past. However, 21st-century technology, for example the AQUALOOP system, exists to safely produce recycled water at a relatively low costs. Combined with the increased need to do so, we should now be striving for new paradigms in water supply and management.
Water efficiency, conservation
Significant reductions in water use can be made by insisting that water-efficient fixtures meet building code, instead of installing older-style high-flow units. These include water-efficient dual-flush toilets, low-flow showerheads, low-flush urinals, flush less urinals, low-flow faucets, and flow restrictors.
External landscaping with minimal water requirements also promotes water savings. Landscaping can be designed with the use of drought-tolerant species, garden mulch techniques that minimize water losses, and subsurface irrigation methods including automated irrigation systems with rain and moisture sensors to ensure optimum application of irrigation water.
To understand where water savings can be made, a detailed water-balance model of the project should be carried out during the design phase. This process will identify all possible water savings by incorporating uncomplicated water-efficiency strategies into the development design. Using this approach, the use of water-efficient fixtures and water-conservation design strategies can reduce an average retail or commercial development's overall water use by more than 40%.
Identifying water-reuse opportunities
Opportunities associated with the design and installation of water-reuse systems will vary significantly from one building project to the next. Analysis of the water-balance model at the outset of the project will reveal any opportunities for alternate water supply, water conservation, and water recycling. Water-balance modeling will also reveal the availability of rainwater and wastewater that could be captured and treated for reuse.
All aspects of building operations that involve water should be investigated and potential sources of water identified. Both internal and external water sources should be considered.
Treatment infrastructure, which often includes filtration and disinfection, will be required to ensure water is of a suitable quality for its intended use. Relatively clean water sources, such as roof water, are relatively straightforward to collect and are suitable for non-potable use with little pretreatment. Ligh contaminated greywater require a higher degree of treatment to make them fit for use. Greywater recycling methods usually have greater treatment costs than rainwater collection and reuse, but they also have the added advantage of year-round water-source availability—so they are not reliant on seasonal rainfall patterns and climate.
Supplying reclaimed water to non-potable applications where the risk of human contact is very low can be an excellent way of offsetting the consumption of potable-water sources. For example, with cooling tower water, the level of direct human contact is minimal. However, to reduce the risk of illness caused by airborne and waterborne pathogens, the level of disinfection prior to reuse should be in line with the risks involved. Non-potable demands include toilet and urinal flushing, irrigation, and cooling towers. Potable demands include water for kitchen use, showers, and sinks It is important to understand the relative proportions of potable and non-potable demand, and this can be achieved through the water-balancing process.
In office complexes, the amount of water used for toilet and urinal flushing is proportionally higher than the amount used in showers. In apartment-, hotel- and rest home buildings, the opposite is true—water used for bathing and showering exceeds the toilet-flushing demand (see Figure 1).
Buildings and complexes with water-cooled boilers or cooling towers for air conditioning require large volumes of water to feed these systems. Properties with large gardens and lawns tend to use a significant portion of their water budgets for outdoor irrigation.
The current level of public acceptance and regulations in some areas mean little opportunity for the use of harvested or recycled water for potable use. To ensure water reuse is an option, the engineer must manage potential public health, operational, and environmental risks associated with the specific application. The primary risks associated with the use of reclaimed water are:
- Public health, which refers to inadvertent contact with the water and subsequent ingestion of pathogens and toxins, particularly relevant in the health and immunocompromised sectors.
- Environmental, which refers to the accumulation of contaminants in irrigated soils and plants or detrimental hydrological effects as a result of water extraction.
- Availability, which is dependent on rainfall patterns and catchment activities, sizing of treatment plants and buffer tanks, and maintenance schedules and equipment downtime.
- Operational, such as potential clogging and fouling of distribution systems and mechanical equipment with suspended and precipitated solids, and staining of toilet bowls.
Given the different treatment requirements of the various rain- and greywater sources and the potentially different end-use water qualities required, a detailed water-balance and feasibility assessment should be undertaken in all system designs.

A solution for local infiltration / attenuation of rain-, storm water or run-off from sewage plants.
With DRAINMAX, rain or storm water can be directly retained at the source and either infiltrate into the ground or attenuated and slowly released into the storm water or sewage system. Therefore easing the pressure on the pipework during high rainfall events.
The system can be completely cleaned thus no loss of infiltration capacity or silting up.
Huge storage capacity (1600 ltr/segment), minimum space requirement and quick installation of the DRAINMAX Tunnel are a few advantages of the system.

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.

Adopt Water Wise habits - change the way you use water and use efficient products and appliances.
- Look for water efficient units when you buy a new:
- Dishwasher
- Washing machine
- Toilets
- taps and shower heads
- Habits
- you'll save over 425 liter a month by spending 2 minutes less in the shower
- plug the bathtub before turning the water on, then adjust the temperature
- a family of 4 can save 94 liters/ week by turning off the tap while brushing the teeth
- turn the water off while you shampoo and condition hair can save more than 180 liters a week
- run the dishwasher only when it is full
- don't use running water to thaw food
much more can be done in and around the hose to be more water efficient, just have a look at your water consumption and have a think about it.

Rainwater harvesting (also called roof-water harvesting or - collection) involves the collection, storage and distribution from the roof, for use inside and outside the home or business.
How can Rainwater be used?
For most rural communities rainwater is the only supply of water for human consumption, around 15% of New Zealanders rely on it for all requirements - drinking, cooking, bathing, laundry, toilet flushing through to watering the garden. This also applies for other communities around the world.
Nowadays, even when mains or reticulated water supplies are available to communities, many people choose to use rainwater that is collected from the roof and stored in tanks to supply their water requirements.
Rainwater is an ideal source for our water requirements and momentum behind rainwater harvesting is building.
Rainwater is a safe and sustainable water supply.
Rainwater that is captured and stored correctly is a safe, economical and sustainable source of quality water. Safety measures can be applied to the manner in which rainwater is captured, stored and dispensed. In fact some people argue that rainwater is safer than water supplied through mains or reticulated water systems.
Mains water is typically stored in buffer-tanks or dams, treated with chemicals such as chlorine or fluoride to kill of bacteria and make it "safe", and then pumped through a network of pipes throughout the community.
It makes sense to catch the rain that falls for free without chemicals.
Main benefits of using Rainwater.
Significant economic, social and environmental benefits can be achieved by using rainwater.
By using a Rainwater Harvesting System to supply water for some, or indeed all of your requirements, you can reduce you dependence on mains water. Our water supplies and qualities are falling and water restrictions are in place in many communities to reduce our overall water usage and protect our supplies.
There is no better quality water available naturally then rainwater, Some say there are health benefits by using rainwater which is not treated with chemicals like most of our water is.
Rainwater falls for free - once you have installed a Rainwater Harvesting System, you use less mains water and can reduce tour water bills. City - and Regional Councils will increase water prices as they look to recover the true costs of providing water to the community.
The cost to the community to supply mains or reticulated water services is becoming more expensive every year. The construction of dams, pipes, and treatment plants is huge and ultimately as tax and rate-payers, we foot this cost.
Rainwater Harvesting reduces the significant dame to our creeks , water habitats and organisms caused by stormwater runoff.

"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.
Rainwater can provide safe and sufficient water in New Zealand and the Pacific. The potential of using rainwater effectively remains largely untapped, especially in urban/town areas, where water safety is a growing issue.
At the same time, rainwater harvesting is not new. In fact, it has been practiced for many centuries: it is the collection and storage of rainwater for multiple use services. overall, it can be used for domestic purposes like flushing the toilet, washing and drinking or productive activities like irrigation.

Rainwater harvesting is a sustainable alternative to other water supply options. It is economically viable, socially compatible and environmentally friendly.
Water harvesting reduces pressure on ground and surface-water sources and it can replenish groundwater sources. In the light of climate change and increasing pressure on natural resources, rainwater harvesting can play a significant role in reducing and overcoming water scarcity. ( Click Here )

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.
