Scottish Water, which is leading the project, says it aims to have the first ten taps installed by the end of March 2019, with the first going outside the Scottish Parliament in Edinburgh next month.
The other areas being considered include Aberdeen, Ayr, Dumfries, Dunfermline, Fort William, Glasgow, Inverness, Milngavie and Oban.
Each tap will be able to digitally track water usage, and will provide information which can be translated into cost and plastic savings and the volume of water used.
In the meantime, Tapwater.org lists places, such as shops and businesses, where you can already refill your bottle for free.
