hello my name's Kate Stokes, I'm the
ecologist at Southwest water and it's a
fantastic job
I get to look after our rivers and
wetlands around the southwest region we
store water in reservoirs we create
down in a valley often more land areas
for areas where there's high rainfall
the water stored behind the stem remember
pipes anywhere in the region that we
need it we have three key reservoirs in
the West Country one in Cornwall on
Bodmin More one in west devon and one on the
east devon and west somerset border up
on Exmoor
hi there my name's Chris rocky and I'm
the company science & Water Quality
Manager it's my job to make sure the
water is always really good to drink
most of the water we treat comes from
rivers and reservoirs and starts off
looking something like this not only is
it looks fairly unpleasant it contains
millions of bacteria parasites and maybe
even some microscopic animals which you
take them into your body
they might will make you ill so to turn
the water from looking like this to
something like this which comes out your
tap every day we pass it through a
number of stages of treatment so the
first thing we do is we have a chemical
to the water called a coagulant and give
it all a really good mix
after a short period of time all of the
chemicals should have come in contact with
all of the water and then we slow the
mixing right now as the mixing slows
down all the impurities come together in
these flocks so they can then be removed
from the water we the set of them to the
bottom of our tanks or we float them up
to the surface so the next stage of
treatment is to pass the water through
deep beds of fine sand and then once all
of the solid material has been removed
and then we had a tiny amount of
chlorine to kill any remaining bacteria
and ensure the water stays good from
here all the way to your tap.
