A spokesperson for the Right2Water campaign said that protests are having an effect.
The campaign has announced that a national demonstration against water charges will take place in Dublin city centre next Saturday.
Thousands of people are expected to take part.
Brendan Ogle said that the campaign has made significant progress so far.
"The campaign has been the biggest mass mobilisation on an ongoing basis," he said.
"We've had ongoing events like the anti-war demonstration 10 years ago, 11 years ago, we've had the PAYE marches in the 1980s, but this is going on for six or seven months now.
"Hundreds of thousands of people, event after event.
"The Government have been forced on to the back foot, there have been major, major concessions in terms of the bills, in terms of the so-called deadlines - I don’t know what deadline we're on now."
