Water Purification

Why you need a Residential Aqua Filter System for your town, tank or bore water supply…

  • Is your TV aerial above your house for birds to defecate on your roof?
  • Do you get rats or cats in or on your roof?
  • Do you get cockroaches in your home?
  • Do you have lead flashing on your roof?
  • Do you live close to a busy road, a farming area or industrial area?
  • Are you unhappy with the taste of your home water supply?
  • Do you have a problem with calcification or clogged water pipes?

If you answered YES to any of these questions, Aqua Filter Residential and Commercial Systems are ideal for you.

Common sources of drinking water


Most people obtain their drinking water directly from a water corporation through a reticulated water supply. However, where reticulated drinking water is not available, some people obtain their drinking or domestic water from private supplies, such as:

  • Rainwater tanks
  • Bores or wells
  • Dams
  • Rivers and creeks
  • Irrigation channels

Water used for drinking needs to be safe to prevent disease and ill health. Private drinking water supplies from rainwater tanks, bores and dams need to be carefully maintained to prevent contamination.
Drinking water may become contaminated from a range of contaminating sources, including animal droppings, microbes from dead animals, chemicals, farm run-off, industrial or mining waste, urban pollution (such as stormwater) and sewage from leaking septic tanks, or other poorly-maintained onsite wastewater treatment systems.

Private water supplies are also at high risk of contamination during and after bushfires, floods and other extreme weather events. Some treatment of your drinking or domestic water may be required depending on its source and its risk of contamination. Groundwater from a shallow bore should be treated in case the water has been contaminated with farm waste or leaking effluent from a septic tank. If your water is dirty or cloudy, you should filter it first because dirt particles can make treatment ineffective.

Research undertaken by the CSIRO and Monash University has found the level of heavy metals in some rainwater tanks in Melbourne is higher than acceptable standards for drinking and has uncovered the possible reasons for these high levels. The occurrence of heavy metals in tank water has been known since the early 1990s, showing that in some instances lead and other metals were present in unacceptably high levels and that this contamination was likely to be due to proximity to traffic or to industrial areas. In the studies using tanks installed for domestic use there were widely varying results, with about a third having high lead levels. The team was concerned that in a few cases where levels of metals were high, water from the rainwater tanks was used for drinking. As none of the tanks were notably close to heavy traffic or industrial activity, the team suspect that the source of lead was most likely lead flashing in the roof catchment.

Contaminated drinking water

Contaminated water supplies have been responsible for major outbreaks of severe gastrointestinal illnesses such as gastroenteritis and infections caused by the protozoan parasites Cryptosporidium and Giardia. Gastrointestinal illnesses can be particularly severe for the very young, the elderly and people with weakened immune systems. Your private water supply can be contaminated by a variety of things:

Animal faeces
such as bird or possum droppings on the roof or from farm run-off into rivers and creeks
Human faeces
leaking from septic systems or wastewater drainage
Pesticides
in run-off from farms or blown on to roofs
Arsenic and heavy metals
in soil from old industrial and mining sites or in some bore water supplies
Dust
containing chemicals blown on to your roof
Air pollution
run-off from roofs in urban and industrial areas that may contain chemicals
Lead
from old paint or flashing on roofs that can flake and end up in tanks
Algae
including toxic blue-green algae (cyanobacteria), which are not destroyed by boiling or disinfection
Nitrates
in some bore water supplies are particularly dangerous to babies
Ash and debris
bushfires produce large amounts of smoke and ash, which can contaminate your water supply
Fire retardants
chemicals used to slow the spread of fire can contaminate water with ammonia and sulphate, making it unsuitable for humans and animals to drink.

Contaminants in your water supply

A range of pathogens can be found in bores and roof-collected tank rainwater including things like, Salmonella, E Coli, Campylobacter, Giardia and Cryptosporidium. Pathogens are faecal material deposited by birds, rodents, and cockroaches, dead animals and insects, farming runoff, pest and crop spraying, etc. Water experts estimate that over 63% of water problems are directly caused by Giardia and Cryptosporidia.

In addition, a wide range of air pollutants such as nitrates, dioxin, Lindane, DDT and Malathione may contain arsenic, heavy metals, and pesticide residues. These chemicals are used in Vineyards, Olive groves, Orchards, and other farming applications. Harmful smoky residues from solid wood heaters, particles from lead-based paints, lead headed nails or flashing on older roofs and gutters can be washed into rainwater tanks.

On-going allergy problems like skin rashes, dryness, and hyperactivity in children like ADHD can be caused through simple things like Chlorine and Fluoride in your drinking water. Many people around the world have concerns regarding the safety of drinking chlorinated water over the long term. In addition, chlorine reacts with water-borne decaying organic matter such as leaves, bark and sediment to create a family of chemicals called Trihalomethanes or THM’s. These include chemicals such as Chloroform, Bromoform and Ichlorobromethane, all of which are toxic and carcinogenic, even in the smallest amounts.

Fluoride is a waste product of the chemical fertilizer industry. Being intensely negative, it unlatches positive hydrogen bonds in enzymes and proteins. Most councils add at least 1 ppm of sodium fluoride or fluorosilic acid to the water supply, even though there has been evidence from around the world that at least 100 medical side effects from cancer to headaches are caused by fluoride in the water.
