The elected officials of the Clisson Sèvre et Maine agglomeration community approved the drinking water prices pour 2025. The facture will increase if consumption remains the same. About 13 %.
For a household of a couple with two children, consuming approximately 110 m3 per ann (the most frequently recorded average at the national level), it will rise by 24 eurospassing from 190 to 214 euros. For consumption at 70 m3 (average for the urban area), the increase is 17 eurosthe bill increasing from 136 to 153 euros.
To form your own idea, the m3 of water goes from 1.20 to 1.49 euros from 0 to 70 m3 consumed ; from 1.35 to 1.56 euros for consumption of 71 to 150 m3; from 1.41 to 1.63 euros for the range of 151 to 6,000 m3 and from 1.48 to 1.71 euros for higher consumption. Added to this, the price of the annual subscription which is increased from 45.82 to 48 euros.
THAT OF SANITATION ALSO
For the first time in 2025, the sanitation bill will be the same for all households in the urban community. The subscription will be 62 euros (instead of 60) and consumption set at 2.40 euros per m3 (instead of 2.003 euros for Remouillé and €2.37 for Haye-Fouassière). The result of the will of elected officials whose community has taken all the skills of the water cycle and progressive smoothing. The strong disparities will no longer be. Next year, for a consumption of 110 m3 (average for 4 people), the household will pay 326.36 euros. For residents of Remouille, the increase will be 46 euros (16% increase) and for residents of La Haye-Fouassière 6 euros (1.7%). For a consumption of 70 m3 (average consumption of residents of the city), the bill will be 230 euros.
Here too, the challenge for the agglomeration is to separate the wastewater and rainwater networks which lead to saturation effects in the treatment plants, with phenomena of overflows in the rivers, as well as polluted. Particularly in 2024, a very rainy year. There are still unitary networks in Clisson and Gorges. “The objective is to renew 3.5 km of sanitation network and rehabilitate 5 lifting stations per year. But also to equip the territory with a network of efficient wastewater treatment plants. As with drinking water, there will be a master plan established for 2025, in order to establish priorities,” summarized Denis Thibaud, mayor of Saint-Hilaire de Clisson.
The intercommunality plans to invest 3.5 million euros per year. This is why Boussay will be equipped with a new wastewater treatment plant. Work is due to start in December. “It must be able to treat the wastewater of more than 3,100 inhabitants equivalent. The community has budgeted 2 million euros,” explained the head of the service, Alexandre Baudouin. Among the other projects to come, the 1,300 meters of network to be renewed in Aigrefeuille-sur-Maine (rue de la Maine, des acacias, de la chapel), the 700 meters to be separated in Boussay (rue du stadium, Chevardin and des brooms) and the 2,500 meters at Gorges (flower district).
Reduce network leaks
In return, the community undertakes to maintain the performance of the network by limiting leaks and renewing the obsolete pipes. As a reminder, if the efficiency of pipes on the territory of the agglomeration is better (88.3%) than at the national level (81.5%)however, it results that more than 300 000 m3 (300 million liters) of treated water is lost due to pipe porosity.
Our objective is to renew 1% of the network each year, or around 7 km.
An investment that should reach 2.3 million euros each year. If the community has for the moment taken care of the most urgent, it must establish a drinking water master plan to prioritize them from 2025.
In the meantime, work has been started, like the 4 km of networks in the villages of Saint-Hilaire-de-Clisson (Beaulieu, Palaire, Boulaire, Priaute) which go extend until March 2025. There will also be upcoming 500 meters of network overhaul rue du Coteau and rue de la Chapelle on Aigrefeuille-sur-Maine; and 300 meters rue du stadium, Chevardin and des Genêts in Boussay.
WHAT ABOUT QUALITY?
During this deliberation on prices, the quality of drinking water was mentioned. Newly elected to the community council, Gwénola Corre, municipal councilor in Gétigné, questioned the community to find out their intentions regarding the future regulations which will require the search for PFAS in drinking water from January 1, 2026.
“These per- or polyfluoroalkyl substances, also called eternal pollutants, are a large family of several thousand chemical compounds which have been widely used in industry since the 1960s. They are found in water in the form of metabolite, such as, for example, chlorothalonil which is a fungicidal molecule mainly used in the cultivation of cereals (wheat and barley diseases), but also on protein crops (peas, fava bean), They are harmful to human beings. They can be responsible for disturbances in cholesterol levels, fertility and also cancers (liver, kidneys, etc.), or even poor fetal development,” she explained.
Also knowledgeable on the subject, Denis Thibaud, vice-president in charge of the water cycle, first reassured by recalling that “100% of the drinking water distributed complied with current standards”. “She comes from Basse-Goulaine where the production plant is very attentive to these questions. She did not wait for this measure to act. There are frequent checks. For example, the activated carbon used to make drinking water is regularly changed to be more effective,” he added.
