Among the highlights of 2025, SIAAP emphasizes the launch of the Multi-year Investment Plan (PPI). This plan is allocated €4.15 billion by 2034 and aims to modernize sanitation in the Île-de-France region. It will also support a new successful bathing season in the Seine and Marne rivers, made possible by investments made under the Bathing Plan, developed in anticipation of the Paris 2024 Olympic and Paralympic Games.
SIAAP's actions also include continuing work to control the organization's carbon footprint. Through these various initiatives, SIAAP reaffirms its commitment to transforming sanitation in Île-de-France to sustainably preserve water resources, natural environments, and territories.
