Paris' River Seine Gets Olympic Makeover for Safe Swimming

The River Seine in Paris, once too toxic for most fish and swimmers, is undergoing a costly and complex cleanup in time for the 2024 Paris Olympics. The cleanup includes improving sewage treatment plants, going after homes upstream of Paris and houseboats on the Seine that were emptying their sewage and wastewater directly into the river, and investing in huge storage basins and other public works that will reduce the need to spill bacteria-laden wastewater into the Seine untreated when it rains. The water quality is already improving, and the river should reopen to everyone in the summer of 2025.
