People Before Profit is calling on local authorities to reject attempts by Irish Water to secure the names and addresses of council tenants.
It comes after Wicklow County Council revealed that it has been asked to supply the information about Rental Accommodation Scheme tenants to the utility company.
The representative for People Before Profit in Greystones, Jacqui Johnston, says the latest attempt by Irish Water to secure personal details of local authority tenants will be seen as further evidence of the "desperate bullying attempts" to impose water charges.
