Inter-season water storage "basins" to fight against droughts...

[izentrop]

on average 1 liter of water out of 5 has already evaporated

I am not miro
In these losses, you can only count the cost of turbines, it will not go very far.

a French person uses an average of 148 liters of drinking water per day

It's a high bar...
I did the calculation over the last six months, at home, we consumed 44 l/person/day, not to mention that we had hosted a person for 2 months

With the cost of the works of slowdown chicanes and speed bumps which are becoming the rule in all the villages, they could easily have renovated the leaky distribution sections, but hey, there were subsidies, so the municipalities made these much more electoral work.

Not sure if it's the leaks that weigh the most...
With mains drainage, the price of water has become incidental.

If you want, but again this is not the subject that was discussed!
The subject is the physical losses of drinking water on the distribution networks.

and the gypsies, and the firefighters, and the building sites, and the purges of the water company.

It's not much, about 3% compared to the 20% leak.

Data from 2012.
Although the latest date from 2021 and have not changed much

Regarding the performance of drinking water services, the evaluation of losses due to leaks (1 liter out of 5
on average) is down slightly, with distribution network performance estimated at
81,5% in 2021.

These losses correspond to an electricity consumption of 19% more for the pumps which raise the water from the groundwater and as much chlorine added. I still think that it does not weigh very heavily on the final bill.
In addition, the water towers are gradually being abandoned in favor of booster pumps, which means less electricity consumed and less chlorine added, since the water remains in the ground and does not undergo any temperature rise...

Already, if we did not use drinking water for the toilets, we would save much more than these 19%...

With a washing machine and a dishwasher that runs every night, we manage to consume 16 M3 / person / year, while "the average domestic consumption per inhabitant is 54,3 m3 per year"...

Good ! not everyone can have a dry toilet, it requires space for a composter...

[Forhorse]

We have dry toilets and we are more like 100m3 per year for 2...well, 4 in reality because there are also 2 horses at home, and a vegetable patch.

The rainwater vegetable garden "of corse"

[Forhorse]

You are probably lucky to live in an area where it rains regularly.
Here from mid-May to mid-October we generally have less than 40mm per month on average.
Suffice to say that my reserve of 1500 liters is empty for a good part of the summer.
To water 100% with rainwater I would need a reserve of water less than 30m3 because the bulk of the rainfall occurs in winter.

[izentrop]

I have 5000 l in a barn cellar that I go up to the garden in a 1000 l, with a pump.
I consumed 2200 l during the drought, quickly filled in 2 storms. The 200 L is because I have 20 L petrol cans that I also filled just before the storm. I put 3 in the wheelbarrow to water at the end of the garden.

The subject is the physical losses of drinking water on the distribution networks

After the 2022 drought and agricultural pumping in the aquifers, despite the ban, the advantage of illegal pumping is that it will limit leaks on the networks by dint of emptying the aquifers, a blessing in disguise!
