Urban Water Agenda


Why an Urban Water Agenda 2030?

"Getting involved in the Urban Water Agenda 2030 is important in order to face together several issues and to take joint action. First of all, to promote a more integrative water management in order to develop a more inclusive city that integrates water, energy, transport, urban policies and encourages a rational use of water. Secondly, to encourage coordination and policy complementarities by considering rural and urban policies independent issues. Thirdly, to reposition people and local governments at the core of the system by supporting inclusiveness and social innovation" 

Célia Blauel, Deputy Mayor of Paris

Paris at work | Using non-potable water

Paris has a dual water network, one provides drinking water, the other non-potable water. Non-potable water is good for uses that do not require potable water. Non-potable water is adequate for street and sewer cleaning, watering green spaces and supplying water to artificial rivers and waterfalls in the Boulogne and Vincennes woods. Vegetation and water presence in the city enhances urban comfort and acts as natural air-conditioning.

Half of the water Parisians consume comes from rivers and the other half from groundwater sources.
Most of the groundwater capturing is from natural emergencies. The most distant springs are located in Normandy and Burgundy, the furthest one lying some 150km from the capital near Sens.
Additional needs are met with water pumped from the Seine and the Marne, upstream of Paris

Main utilities providing water and waste water services

The City of Paris and its public operator Eau de Paris are in charge of water provision and delivery.
The City (Paris sanitation section) is also responsible for collecting wastewater while the” Syndicat interdepartemental pour l’assainissement de l’agglomération parisienne” (Paris urban area wastewater treatment authority- SIAAP) is in charge of wastewater treatment for Paris.
