WATER
MINING
The
water mining concept involves choosing an area where water is needed,
extracting waste water from an underground sewer, treating it to a
high standard and then recycling it for local use. The solids
separated from the waste water are returned to the sewer, and move on
for efficient treatment at the main waste water treatment plant. The
major benefit of water mining is that water does not have to be
brought back from larger treatment plants to the area in need, which
means money does not have to be invested in large underground pipe
systems. The concept has the potential to be used in many public
parks and gardens.
