Water puri cation of the
Brivadois reservoirs

Water puri cation in rural areas (France) Chlorination
The water sourced from the catchment basins of the Brivadois must be
chlorinated for regulatory reasons at a rate of 0,3 ppm even when
the reservoirs only serve a few dwellings. The syndicat de gestion des
eaux du Brivadois (Brivadois Water Management Syndicate) operates in 3 pumps for 3 reservoirs

The pressure and the flow activate the motor piston which in turn is connected
to a dosing piston.

The disinfection additives are dosed proportionally, and continually injected
with the chosen dosing water.
The dose of concentrate is directly proportional to the volume of water
passing through the pump, regardless of variations in the collection flow.

Chlorination, placed upstream of the reservoirs, provides effective
protection against the development of bacteria, protozoa,
Escherichia coli, Guardia intestinalis, Cryptosporidium, etc.
