“Why would my water tank be dirty? It’s just rain water!”
Roofs and guttering are the main catchment area for household water tanks so its not surprising that substances such as heavy metals (from iron roofs, and paints), pesticides, decomposing leaf matter, bird and rodent carcasses and droppings, plus dust and grime can quickly make its way into your tank. This builds up over time to harmful levels.
When using roof water for drinking you must clean spouting regularly and keep your roof clear of bird and animal droppings, along with having your water tank inspected and/or serviced once a year. Healthy Water Tanks can help with all of this.
“How do I know if my water tank needs cleaning?”
If you are lucky, you won’t know…… if you are unlucky you will know by how unwell you and/or your family are feeling. Symptoms of a sick tank may include poor tasting food and drinks, difficulty getting clothes really clean, build up in pipes and appliances. Physical symptoms include stomach upsets or vomiting, caused by organisms such as campylobacter, cryptosporidium, salmonella and giardia. People will often attribute the symptoms to something they have eaten rather than the water they have consumed, or washed in.
The best way to be sure is to have your tank inspected by our team at Healthy Water Tanks Limited.
“How can my water tank make me sick? Could bacteria really exist in my water tank?”
Yes , there is a possibility that you could have any one of a number of different bacteria in your tank , these could be organisms such as campylobacter, cryptosporidium, salmonella and giardia.
Food and water borne diseases such as Giardia, Campylobacter and Cryptosporidium are unfortunately widespread in New Zealand. The parasites can live in the environment for long periods, especially in lakes, rivers, streams and roof water.
The Ministry of Health have produced several information pamphlets regarding the treatment and prevention of Campylobacter, E.coli and Salmonella, and Cryptosporidium and Giardia.
“Is there any way of testing to see if I have a sick tank?”
You can have your tank water tested by the Local Authority but this can be costly depending on what it is that you are testing for. It is usually more cost effective, and more reassuring, to have your water tank professionally cleaned by Healthy Water Tanks.
“I don’t want to let my tank run dry to clean it – I need my water!”
