SIAAP - GREATER PARIS SANITATION AUTHORITY

A key provider of sanitation services

SIAAP- the greater Paris Sanitation Authority- was established in 1970. It transports and treats wastewater for nine million people in and around Paris, along with stormwater and industrial water, contributing to a thriving natural environment in the Seine and Marne rivers.

SIAAP covers four French departments : Paris, Hauts-de-Seine, Seine-Saint-Denis, and Val-de-Marne, along with 180 municipalities in the Val d’Oise, Essonne, Yvelines and Seine-et-Marne departments, which have signed an agreement with the SIAAP.

The SIAAP board comprises 33 local councilors from the four founding departments.

SIAAP has an annual budget of 1,3 billion euros to provide public services in and around Paris, the European city with the highest population density.

SIAAP and its 1,700 employees manage and operate 440 km of pipes, six treatment plants and 12 stormwater retention basins.

Contributing towards improving the quality of the Seine and Marne rivers

The SIAAP’s main mission is to process the waste water from the Paris urban area to contribute towards reaching the good condition targeted by the framework directive on water (DCE). The achievement of this mission can realized with an optimal capacity of the Seine to accept larger or smaller quantities of pollutants, notably depending on its flow. To optimize the quality of purification of the water produced, the SIAAP is developing and implementing a quality prediction model for the Seine.

Working in the public interest

For a number of years, the elected representatives on the SIAAP board of directors have been pursuing a policy of international cooperation to promote sustainable improvements in access to safe water and sanitation for people in developing countries. Drowing on its experience in decentralized cooperation and buoyed by the expertise gained and constantly honed through the initiatives it supports, SIAAP has gradually established itself as a  key player in promoting international outreach programmes.
