Why you need a UV Water Filter System

If you are harvesting rainwater – You Need a UV System – No ifs No buts.

Let us explore this bold statement a little; rain falls from the sky and lands on your roof. What else is on your roof? Well, a variety of birds, occasional possums, moss, mould, lichen, insects, snails, slugs, dust, pollen and I could go on. All living things poo. Your rainwater runs through the poo/faeces, dust, pollen, debris and it all ends up in your water tank.

We know all living things carry E-coli and bacteria, we also know birds, and possums transmit protozoa like Giardia through their poo, on their way to finding a new host – YOU. All rainwater stored in water tanks have some levels of faecal coliforms present. In our experience, we know that 70% of rainwater tanks have E-coli present too.

Ecoli is an indicator that there may be other pathogenic micro-organisms present in your water such as giardia, cryptosporidium & campylobacter. (ecoli is relatively cheap to test for). Insects, mosquitos, snails, worms and larvae are also often found in your water tank. These foreign invaders eat and live on the organic matter that’s on the bottom of your water tank, and multiply rapidly as a result.

“She’ll be right mate, I’ve been drinking this water for 20 years, and I’m OK”    – Mantra of a typical old-school Kiwi bloke, usually while they, or a family member,  have the trots and I am recommending they spend some money to fix their water contamination. – Steve Reynolds, founder of-   Are You The Filter, Aqua Filter Rodney & Pure Water Services North Ltd

No, it is not alright, we regularly work with people and families who have serious health issues caused by the pathogens in their water. De-hydration, vomiting and diarrhoea can be very serious, often resulting in children and elderly in hospital. Together we can fix this, your water at home can be safe to drink from every tap, every day.

How does a UV Water Filter System work?

Proven Technology – Ultraviolet water filtration is proven in sterilising water in NZ. It uses Ultraviolet light to disinfect harmful micro-organisms commonly found in rainwater storage tanks on homes, bach’s, farms, schools and lifestyle blocks. UV is a long-established, proven mechanism for treating water, making it potable and safe for homes and workplaces.

DNA Disrupter – UV rays are found in the electromagnetic spectrum, lying between x-rays and visible light. They are a type of energy that irradiates the water as it passes through the UV chamber or reactor. UV light disrupts the strands of DNA at the genetic core of the bacteria, making it unable to reproduce and therefore unable to form infectious colonies which could make you sick.

Highly Effective – UV light can only be effective against micro-organisms if it can see them, bearing in mind we can’t see any of this as its all sub-micron. For this reason, we always put the UV as part of a filtration system with a 1-micron filter. Traditionally people have used a 20-micron pleated filter cartridge followed by a 1-micron polyspun depth cartridge. We have found this to be less than effective with the 1-micron filter blocking up quickly in most places. Worse is a string wound 1-micron cartridge which never blocks – the reason being this type of filter loads up and then releases large chunks of debris into the water, which is the worst-case scenario for the effective dose of the UV system.

Clean Sediment Free Water – UV light must be allowed to freely penetrate all the water, bear in mind we can’t see the bacteria and we can’t see the sediment it hides behind as it goes past the UV light. UV water filter systems work best if there are 2 dual gradient filters in front of the UV lamp. We set all our systems up with a 75-25 micron dual gradient filter first and then a 25-01 micron filter as the second filter. This ensures the cleanest water possible from a sediment type filter on rainwater. When we service these UV filter systems you can see the dirt load up the different parts of the dual gradient filter cartridges.

This means the sediment filters load up evenly and nothing gets past the 1-micron filter that the UV light can’t penetrate.

  • UV is a safe natural process
  • UV uses no chemicals
  • UV doesn’t add anything to your water
  • UV doesn’t affect the taste of the water
  • Ultraviolet disinfection is a physical process
  • UV effectively disinfects 99.99% of micro-organisms
  • UV is cost-effective, requiring only an annual service
  • UV systems are more effective than adding chlorine
  • UV systems are energy efficient
  • UV lamps need replacing every 12 months
  • UV system best practice requires a 1-micron pre-filter
  • Our best practice is 2 dual gradient filters pre-UV
  • UV light is not residual – Only works when the water goes past the lamp, that’s why its essential to have your water lines professionally sterilised each year.

What does a  UV Water Filter System kill?

Bacteria and Viruses – UV or Ultraviolet water filtration systems are your best line of defence against bacteria and viruses. UV water sterilisers have been proven to render harmless or de-activate 99.99 % of bacteria and viruses that are commonly found in New Zealand’s rural water supplies. These water supplies can be rainwater harvested from your roof, bore or well water or surface waters such as springs, streams and rivers. The most common source where we use ultraviolet filtration, on is rainwater or tank water.

E.coli bacteria are commonly found in the human intestinal tract. However, there are some types, like STEC Shiga-toxin producing E-coli,  which are harmful and can cause severe stomach cramps, mild to severe diarrhoea and vomiting. These types of E-coli are transmitted through food and water. In water, these get into your water tank through infected animals crapping on your roof, same as Giardia.

Giardia and Cryptosporidium –  Giardia is a relatively new parasite introduced to New Zealand in the late ’80s. Giardia and Cryptosporidium are protozoa cysts and are parasitic. This means they travel from host to host in cyst form waiting for you to become the new host. They live in your gut and reproduce rapidly. They are transmitted mainly by birds, but also possums and rodents, which all get on your roof and defecate and crap everywhere. Rain washes the faeces/poo into your tank and you drink it making you the new host.

Giardia and Cryptosporidium cause severe diarrhoea and dehydration over a prolonged period of time, it’s not pleasant and once you have had it once you are more likely to have it recur, a bit like malaria. Giardia is now a notifiable disease in NZ. New Zealand has one of the highest incident rates of Giardia in the developed world.

Example of Fatalities from Protozoa – People have died from these parasites, for example in 1993 in Milwaukee 69 people died following an outbreak of Cryptosporidium, having drunk water from the towns main municipal water supply. Read more. It was found that Chlorine was not effective against Giardia or Cryptosporidium, however, UV water treatment was very effective and in fact easier to destroy than bacteria or E-coli.

Bio-Film – UV water filtration is the most cost-effective method for making your drinking water safe. However, UV installations and correct annual servicing must be done to the manufacturer’s recommendations in order for the UV to work properly. In our experience, over the past 18 years, very few systems are installed correctly and even less are maintained to a satisfactory standard recommended by the manufacturers, resulting in bio-film build up which can cause risk of illness.

UV ineffective unless correctly installed and serviced – We recently upgraded a commercial facility used as a cafe, where the UV had not been maintained correctly. The lamp had been changed, however, the system had never been stripped down and cleaned. We found algae growing on the quartz sleeve and masses of bio-film inside the pipes feeding the cafe, home and workplace. It is NOT ok to simply replace the UV lamp and change the filters, it’s not what the manufacturer recommends and you are putting your family or workplace at severe risk of ill health.

 Commercial UV Filter Systems

Design – Engineering – Specification – Installation – Schedule Maintenance

We regularly service and install new complete systems for our commercial businesses and are helping them comply with the changing regulations regarding water safety and their obligations. Some clients are now considered small water suppliers and have to comply with section 10 of the Drinking Water Standards for New Zealand 2008. We help with system specification, design and compliance. We can write water safety plans and make sure you comply with your legal obligations.

Often Commercial UV systems are part of a larger system. Commercial water treatment is often required, especially on surface waters or large flow, large volume requirements. UV water sterilisation is usually the end part of the solution as the water quality needs to be very good before it passes through the UV system.
