COLLECTING RAINWATER – ENSURING A SAFE, PURE AND HEALTHY WATER SUPPLY WITH TANK VAC - 31/03/2017

USAGE OF RAINWATER COLLECTION TANKS IS ON THE RISE

Maintaining clean water tanks and a clean water supply can be challenging – and finding an effective solution is crucial when considering rainwater collection. Fortunately, HRV offer a tank cleaning product to ensure your water tank is kept clean and healthy. In this article, we’ll be taking a look at the HRV Tank Vac System and the Home Water Filtration System to see how they can help you achieve a clean and pure water supply for your home.

More and more New Zealanders are collecting rainwater as a natural source of water for their households. Why? Assisting with environmental sustainability, relieving pressure on existing infrastructure and enabling cost-effective water supply solutions are common reasons. When rainwater collection is easy to achieve and the water is free to use – the case for a DIY water supply solution is compelling.

Traditionally, water collection tanks were, and still are, commonly used for households in rural areas not connected to town water supplies. The rural households rely on rainwater as their only source of drinking water and water for bathing, washing clothes, cleaning, flushing toilets along with a host of other uses.

Rainwater collection is no longer only concentrated in rural areas. Rainwater collection is becoming increasingly popular with households in towns and cities as an alternative to metred and paid water supplies. Auckland has seen a rainwater tank boom as a result of council-owned Watercare stating their future intentions to cut per capita water use by 15 percent.

Some households consider rainwater collection an efficient and more environmentally sustainable way to source their water, while others are motivated by the cost savings. Regardless of the reasoning, water tanks are being more commonly utilised and, as with any process, there are benefits and there are potential issues:

 

BENEFITS OF RAINWATER COLLECTION IN WATER TANKS

  • Rainwater, a precious natural resource, can be easily collected via the roof of the house and directed into a water storage tank
  • Water is a commodity and, with water bills continuing to rise due to increased population and pressure on existing infrastructure, there are significant cost savings to be had by reducing the consumption from an expensive metred water supply

 Roofs Are Commonaly Contaminated With Bacteria and Dirt From Bird Droppings

HEALTH ISSUES COMMONLY ASSOCIATED WITH WATER COLLECTION TANKS

We are fortunate in New Zealand; our rainwater is a relatively pure natural resource. But it can easily become contaminated, either as it flows across the roof or within the water tank itself. There are many causes of contamination which can pose significant health issues: 

  • Bird excrement can contaminate the rainwater as it flows over the roof
  • Roof paint can contaminate the water if it is not water tank safe (some roof paints contain high levels of lead). Also damaged or worn paintwork can flake off and get into the water tank
  • Soil, plant matter, insecticides and road vehicle emissions can get into the water supply via particles on the roof. Even small amounts of sediment can become a breeding ground for dangerous bacteria which can cause serious health issues
  • Effective and regular cleaning is required to keep tank water clean and safe to drink. Cleaning a water tank can be a difficult and expensive business – and there are risks associated with unsafe methods of cleaning
  • All of the above issues can lead to water contaminants such as salmonella, campylobacter, E coli and giardia. Research from the Auckland Public Health Protection Service showed that 56 percent of the water collected from roofs exceeded standards for faecal contamination due to birds, cats and possums.

The health risks are very real but there are steps you can take to mitigate the risks and keep your drinking water and general water supply clean, safe and healthy for your family:

 HRV Tank Vac Filters Sediment From Your Collected Rainwater

TANK VAC – AN INNOVATIVE PRODUCT THAT ENSURES YOUR WATER COLLECTION TANK IS KEPT SAFE AND CLEAN

The HRV Tank Vac System ensures the safe storage of clean rainwater using an innovate vacuum system devised and patented by an ingenious New Zealander. The Tank Vac is powered by gravity and does not need any electricity or external power supply. This makes the Tank Vac System an extremely attractive tank cleaning system from a cost perspective – as it costs nothing to run!

 Tank Vac is also an ideal solution for remote bach owners who can’t get to their properties regularly to clean their water tanks. With Tank Vac you can rest assured that your bach water supply and water tank are kept clean, safe and healthy all year round.

 

HOW DOES TANK VAC WORK?

  • Any sediment or debris that gets into your water tank will accumulate at the bottom
  • As the tank fills with rainwater – the water level rises. When the water level reaches a certain point, a siphon is activated. This creates a vacuum which sucks up all sediment and debris from the bottom of the tank via a small pipe which runs across the bottom of the tank
  • The debris and dirty water is then flushed out via the TankVac’s Siphonic Inducer, leaving your household with a clean and safe water supply to use whenever needed
  • As the dirty water is flushed out, the water level in the tank drops and the vacuum stops until the water level rises again – a smart and efficient system!
  • Tank Vac can be used in concrete or plastic tanks and is easily installed into a full or empty tank

  

COMBINE THE HRV TANK VAC SYSTEM WITH THE WHOLE HOME WATER FILTRATION SYSTEM TO ENSURE THE CLEANEST WATER POSSIBLE

Combining the Tank Vac with HRV’s Whole Home Water Filtration System can be easily done and will provide your household with the cleanest water possible. The home water filtration system uses a multi-stage filtration process which captures any sediment, bacteria or other impurities your water may contain.

You may ask why your water would contain any impurities after being cleaned by the Tank Vac System – good question! The four-stage water filtration system captures not only sediment but also chlorine, chlorine by-products (trihalomethanes) and heavy metals.

The whole home water filtration system also contains a magnetic ionizer which reduces scale build up.

The final step in the HRV family of water filtration products is to install the UV Water Treater which uses ultra-violet light to kill 99.9% of any microscopic bacteria that may still be present in the water. The efficiency of UV filtration is increased by the removal of sediment and scale from the water flowing into your house. This makes the HRV UV Water Treater an ideal partner for your Tank Vac and Whole Home Water Filtration System.
