These charges can represent a significant share of the water bill (about one-third of water supply and sanitation bills for households, in the case of France, as an illustration). This is reflected in the level of prices (which have increased, at times substantially, over the last decade) and in the structure of tariffs (which better reflect consumption and treatment costs). Water tariffs in Denmark reflect the choice to recover all supply and sanitation costs from users (see Box 3.2).
