With the topic of water and brewing coming up from time to time it would be nice to have an airlocked central post of all the water around the country that you can go to.
I'll start up with Canberra Water Breakdown
Canberra water comes from two primary water treatment plants. One uses chlorine gas to chlorinate, the other uses chlorine gas and UV during chlorination. There is no chloramines used in Canberra water (thank god).
The water treatment plant has a production capacity of 250 megalitres (million litres) a day. The treatment process involves the following steps:
coagulation and flocculation
optional dissolved air flotation
dissolved air flotation and filtration or direct filtration
disinfection by chlorination
ultraviolet disinfection
pH adjustment and stabilisation with lime and carbon dioxide
fluoridation by sodium silico fluoride.
Test Typical value Unit
pH between 7.5 and 8.5 pH units
Alkalinity (total) 35.8 mg/L as CaCO3
Colour (true) 2.38 Pt-Co units
Turbidity 0.47 NTU
Fluoride 0.91 mg/L
Total Hardness 39.6 mg/L as CaCO3
Iron 0.033 mg/L
Manganese 0.010 mg/L
Aluminium 0.033 mg/L
Copper 0.018 mg/L
Lead 0.0004 mg/L
Sulfate: None given by ActewAGL, only that the detection level is 1mg/L
