Gas Cylinder & Water Pumps

Gas Cylinder Bushfire Safety by Elgas – Video

Tips by Paul Hunter 

  1. I purchased a single impeller Onga firefighting pump with Honda petrol engine. Must be a Honda.

Pros and cons of single impeller Vs twin impeller pumps depend on application and RIS will advise.

Firefighting pumps deliver high volumes of water  [as opposed to pressure which they also deliver] and must be petrol or  diesel powered.

2.   No system is a guarantee of survival but, I  believe, now essential due to climate change / this extreme drought and  the future implications.

3.  These pumps deliver from about 400+ litres of  water per minute [mine is about 600 litres] depending on head so  availability of water and quantity is key = No good putting a 600 litre a  minute pump on a 3,000 litre tank!

I initially plumbed my system [4 roof sprinklers  & 4 high pressure tap offtakes from each corner of the house] to my  tanks which hold 70,000 litres when full but then realised I needed it  to be optionally sourced from my dam because a]  the tanks may not be full and b] the pump pulls 600 litres per minute.

4.  Assess what quantity of water your tanks hold  and how much water you harvest off your roof for collection. Consider  installing a dam for various reasons including firefighting. But get an  expert dam builder. Assess the suitability of  your site and subsoil for dam building – you need good clay.

If the neighbours have dams chances are you can build one which holds water too.

5.  Depending on your current tank storage capacity  and the state of the river consider pumping from the river to one or  more tanks [as the situation demands] and treating with chlorine [dosage rates available on the internet but I can tell  you what I do] allowing that chlorine to burn off over a few days to  provide drinking water back up.
