the building control officer (BCO) to apply and police it.
“The question is, why are there no appropriate standards
for grey water and rainwater harvesting and domestic
water in buildings?”
USES OF PLASTIC STORAGE TANKS
Plastic storage tanks can be used for rainwater and
grey water harvesting, municipal backup supplies,
and sanitation applications. Water can be stored
above ground where it can easily be connected to
guttering through simple pipe networks to fill the tank
automatically when it rains. Underground water storage
works on the same principle, but the tank is buried and
takes up less space. A submersible pump is required to
dispense the collected water.
Municipalities can install a bigger network of water
storage solutions and tanks to collect a greater volume of
water, which can be used during a disruption or cut-off
from the mains supply. Fully integrated water storage
solutions provide a self-sufficient, more automated water
collection system from mains supply to a predetermined
level, with the remaining volume available to store
rainwater. This water is then filtered or sterilised to be
used for full domestic water supply.
