In parallel with the rise in energy prices, the price of water has also been increasing since January. In Clermont-Ferrand in the Puy-de-Dôme for example, its price is 10% more expensive than in 2022. On Europe 1, the economist Alexandre Mayol explains that the energy surge entails an additional charge for suppliers .

Many water unions and communities have voted for substantial increases in water from January. An increase partly linked to the rise in energy prices, which affects many sectors such as baking. For example, in Clermont-Ferrand, the prefecture of Puy-de-Dôme, the price of water is 10% more expensive than in 2022. Europe 1 takes stock with Alexandre Mayol, lecturer at the University of Lorraine.

A charge for pumping and water management

“Energy is part of the costs for a lot of supplier companies, and in particular for water. In terms of pumping, treatment of the water management system, this represents a load”, explains the economist at the micro d’Europe 1. “As energy has increased, this is reflected in prices,” he observes.

Alexandre Mayol recalls that communities and businesses “do not benefit from the regulated electricity tariff”. “As they are on the energy market, if the price increases, it increases the costs”, continues the lecturer. The other point to emphasize in this price increase is the fact that the price of water is fixed “on an annual basis and often at the beginning of the year”, he indicates. Consequently, “we must make a simulation of budget forecasts. Some (local authorities) will take safety margins to avoid problems of anticipation”.
