3. n Wastewater
management
encompasses
a
broad
range
of
efforts
that
promote
n Effec/ve
and
responsible
water
use
n Proper
Water
treatment
n Proper
Water
disposal
n Encourage
the
protec/on
and
restora/on
of
our
na/on's
watersheds.

4. “It
is
the
water
which
is
discharged
from
buildings,
houses
etc
which
is
unfit
for
consump/on.”

5. n Most
wastewater
from
a
building
is
sanitary
wastewater
which
includes
n human
waste,
n
cleaning
solu/ons,
n oil
and
grease
from
cooking,
n food
par/cles,
and
n soil
from
cleaning
clothes
and
floors

6. n Commercial
establishments
may
also
discharge
metals,
acids
and
bases,
and
small
par/cles
of
plas/c,
glass,
stone,
etc

7. n If
not
treated
properly
causes
water
pollu/on
n Can
lead
to
various
health
hazards
n Can
cause
soil
pollu/on

8. n Any
oxidizable
material
present
in
a
natural
waterway
or
in
an
industrial
wastewater
will
be
oxidized
both
by
biochemical
(bacterial)
or
chemical
processes.
n Since
all
natural
waterways
contain
bacteria
and
nutrients,
almost
any
waste
compounds
introduced
into
such
waterways
will
ini/ate
biochemical
reac/ons

9. n Those
biochemical
reac/ons
create
what
is
measured
in
the
laboratory
as
the
Biochemical
oxygen
demand
(BOD)
and
Chemical
oxygen
demand
(COD)
n Both
have
been
widely
adopted
as
a
measure
of
pollu/on.

10. n REUSE
n RECYCLE
n WATER
TREATMENT

11. n Some relatively
clean wastewater
can be reused
without treatment
n Graywater is
wastewater
generated by
washing, laundry,
and bathing (not
from toilets)
n 50-80% of domestic
wastewater
n Reused for irrigation
or flushing toilets

12. n Closed-loop
treatment systems
n Used to capture, treat,
and reuse waste water
on-site
n E.g Car wash System
n Wastewater
reclamation
n Treats waste water and
use it for a different
purpose
n E.g MC waste water
treatment and use for
irrigating parks

13. n Wastewater is
transported to an
(on-site or off-site)
treatment facility,
treated, and
discharged into a
water body
n Used
for
drinking
purposes
