Catchment and dams – our natural waterways
The Water Purification Scheme would supplement the ACT's water supply by adding purified water to the Cotter
reservoir. From this point, the purified water would become part of our existing water
supply system.
Construction to enlarge the Cotter dam was one of the options explored and considered
during ACTEW's detailed studies in 2004/05. This would allow for the extra water
to be stored for our future needs.
