Drinking water and sanitation

Amount of money paid by the users connected to a collective sanitation system, on their water bill. Users of an on-site sanitation facility must pay a special fee to finance the public on-site sanitation service costs.

Process used for treating sewage sludge, changing it from a liquid state to a more or less solid state. Sludge dewatering reduces its volume.

Use of wastewater, in agriculture for example, after passing through the treatment plant, instead of being discharged into watercourses, bodies of water or coastal waters. This re-use allows, on the one hand, mobilising an additional water resource and, on the other, protecting the water receiving the treated wastewater.

A structure for the storage of water taken from the natural environment before its supply to a system. Water reservoirs are a buffer between water supply and demand.

Volume of water consumed by users (private, industrial and other) and the public utility (for the management of the drinking water system) in relation with the volume of drinking water introduced into the supply system.

Action to dispose of, discharge or allow the flow of runoff water (mainly from rainfall) and wastewater (produced by human activities) into the sewers of a city.

Rehabilitation of a network of drinking water supply, sanitation or of degraded industrial fluid. The rehabilitation of a network contributes to restore optimal conditions for its exploitation

Reuse of sewage sludge, especially in agriculture (composting, land application) or in industry (cement, for example).

All the private pipes, buried or not, located outside the house, between the sanitary (bathroom, toilet) or household appliances (sink, laundry tray...) and the junction manhole.

Device for rising up, back flowing or compressing fluids.
