Water, water everywhere… but do you know if it is safe to drink?

Water is classed in many different ways, but what are the differences between potable, raw and dirty water?

Potable Water
Potable water is drinking water. The water can be used in the preparation of food and can be drunk without any risk to health.

Raw Water
Raw water is untreated water that is found in the environment such as rain water, ground water, rivers, lake and well water. It is unfiltered and contains dirt, debris, chemicals, ions, minerals and micro-organisms that may be harmful to health.

Dirty Water
Dirty water is contaminated water. Contamination may include debris, oil, chemicals, sewage or nuclear waste. The water can also contain life threatening diseases such as Cholera, Hepatitis A, E. Coli, Schistosamiasis and Legionellosis.

Diving in a potable water storage tank requires clean equipment

Environmental considerations must always be taken into account when diving in water. Equipment is sterilised before use when diving in raw water to prevent the migration of unwanted alien species such as freshwater Quagga mussels (Dreissena rostriformis bugensis), Demon shrimp (Dikerogammarus haemobaphes) and Killer shrimp (Dikerogammarus villosus).

Invasive species threaten our own native life and precautions prevent their accidental spread on diving equipment, boats and pontoons.
