I do not understand your question ?perplex wrote:If the tablecloths are full, so are the basins! But when summer arrives and the “other” has pumped his basin, it’s over (in principle).
At this time, the surface of the basin will slow down the filling of the water tables, but the water pumped will no longer be pumped by the "other".
Given that on average the reserves are 10 m high, their surface area is tiny compared to the concrete and asphalt surface of the department, so it has no weight in the balance. https://www.vendee-eau.fr/letat-de-la-ressource/
It’s still preferable to summer pumping, right?
This was done and further proven by François Arnoux aboveperplex wrote:Basins should be authorized after and only after a local serous rainfall study.

According to the report, the project would allow "an overall improvement in the level of water tables in spring-summer" and an increase in the flow of watercourses (+5% to +6%).
