Works were also completed at Brewery Lane and have since moved to the next section between Cabey’s Lane and O’Halloran’s Lane.
Works on Post Office Lane commenced last week and will continue for approximately two more weeks.
Trial excavations were also undertaken on Cook’s Lane to ascertain ground conditions for excavation work.
Deputy Carey said that Irish Water thanked the local community, businesses, homeowners and commuters for their patience and cooperation during the excavation and pipe laying process.
The work is being undertaken in conjunction with Clare County Council’s Public Realm Regeneration project which will concentrate on the mediaeval area of the town.
