Engineers have been carrying out surveys in Donegal’s biggest town last week.
Now workmen are getting ready to install meters on many of the housing estates in the town.
Work is expected to get underway proper tomorrow.
Residents in Ballymacool however have told Donegal Daily they will protest at any attempts to install meters there.
Gardai have already drawn up contingency plans to step up patrols in all areas where contractors are planning to work over the next few weeks.
However a spokesman for some residents in Ballymacool told Donegal Daily: “We will hold peaceful protests and have warned neighbours that we do not have the authority to prevent meters being installed when they are away from their homes.
“Anyone who wants to object needs to be at their home when work begins.”
Similar protests in Castlefinn and Convoy prevented meters being installed.
Residents in Drumkeen also persuaded workmen to fill in holes where they had planned to install meters there last week.
