Starting September 1, 2026, residents and businesses on Thasos are now subject to the updated service charges established by the island's water and sewerage operator. The revised fee schedule, formally adopted through board resolution 90/2026, replaces the previous tariff system and will remain in effect through 2029. While the announcement confirms that substantial adjustments have been made to both rate calculations and invoice generation methods, full details of the specific changes remain pending public disclosure. The utility company has indicated that additional information about the modified billing procedures will be released to customers and stakeholders.
