Waterbedrijf Groningen is concerned about potential costs reaching millions of euros as homes in earthquake-affected areas are reinforced, requiring updates to drinking water pipelines. Wim den Hertog from the company highlighted that adjustments are essential in regions undergoing reinforcement, estimating significant financial implications. Currently compensated by the government with 5 million euros, more funding is anticipated to prevent future price increases for residents, as the company has already raised prices slightly due to the seismic situation. Local officials stress the need for shareholders to ensure costs do not fall on citizens.
