The spring is not diaclistic,
but a Vauclusian resurgence.
:12:04
Let's not forget that, eh?
:12:07
Thus, the water flowed between
two impervious strata,
:12:11
pressing against the upper layer.
:12:14
The pressure generated
forced water into the tank.
:12:18
Gravity then ensured the flow of
water from the tank to the village.
:12:24
Right. Gravity.
:12:26
At the request of your mayor
and with local authority permission,
:12:32
we have examined the cause
of the present obstruction.
:12:35
First, where is the source of the water?
:12:38
I have here a useful document...
:12:45
It's an analysis by the Chief Engineer
clearly stating the results of experiments
:12:51
made in the region some five years ago.
:12:55
Sadly, there's no indication
whatever of a spring in this area.
:13:03
There's no stream within the
orography of the Huveaune river.
:13:08
What does that mean?
:13:12
The source of your water
is some way away.
:13:17
- I want to speak.
- This isn't the time.
:13:20
I'll make it short.
:13:22
Just let him turn on the water.
He can explain later.
:13:30
I'm not a plumber.
:13:32
Now, the first hypothesis is drought.
:13:36
The trouble may be due
to a drop in the water table.
:13:42
The watercourse is determined by seams
of dolomite in the limestone.
:13:47
It can cross the seams via a network
of siphons. You know what that is?
:13:51
You use them in winemaking.
:13:54
Precisely. During the rainy season,
the siphons are reactivated
:13:59
as soon as the water table rises
to its normal level.
