| When
the sewage enters the treatment works, it passes
through large screens which remove any large debris
such as rags and plastic.
The sewage then needs to be transported to
the highest point of the site so it can flow
by gravity through the rest of the works. This
can be done using either electric pumps or an
Archimedian screw.
The water now passes through fine screens,
with holes just 5mm wide to take out any further
debris. Removed waste is compacted and taken
away to a licensed waste disposal site.
