This document discusses water recycling and reuse. It begins with an introduction that defines grey and black water and explains that recycled water can be used for many purposes if treated properly. It then discusses where recycled water can be used, such as for toilets and irrigation. The benefits of water recycling include conserving fresh water, reducing costs, and generating byproducts like electricity. Finally, it presents three case studies of systems that reuse grey water for functions like flushing toilets and watering plants.

3. The term water recycling is generally used synonymously with water
reclamation and water reuse”

4. Introduction
• Water recycling mainly refers to reusing waste
water such as from residential, industrial places,
agricultural irrigation, etc. to implement in
something beneficial. Water recycling offers a
great deal of benefits for today’s generation as
over use and waste of water led to fresh water
shortage. This not only saves water but also
saves money in different effective ways and the
treated water becomes multi-functional.

5. The type of recycling also depends on the source of the waste
water. “Grey water”, is the water which come from non-toilet
plumbing, like basin, shower and taps. “Black water” is the toilet
plumbing water. Water from kitchen and dishwashers are
categorized as black water because they contain harsh chemicals,
pathogens and grease.
“Recycled water can satisfy most water demands, as long
as it is adequately treated to ensure water quality
appropriate for the use”

6. So what basically
happens is the water
from the shower + the
wash hand basin will
be collected and then
treated.
This recycled grey
water will be used to
flush toilet..
This reduces waste
Grey water system

7. As we see from the picture ,
black water is not easy to reuse,
it has to go through a lot of
processes to get treated unlike
grey water which can be reused
if the grey water system is
stored in the bathroom.

8. Where it can be used
• Toilet closet
• Sink
• Basin
• Shower
• Bath tub
• Any furniture piece that uses water

9. Installation methods

11. Benefits
• By recycling water, we conserve fresh
water for sensitive aquatic lives. Certain
aquatic plants, animals and fish depends
on natural and adequate flow of water,
which when disturbed, pushes these lives
to extinctions.
• Recycled water can be used for creating or
enhancing wetlands. Wetlands keep a
major role in wildlife and wildfowl habitat,
water quality improvement, flood
diminishment, and fisheries breeding
grounds, etc.

12. • Irrigation lands where recycled water is
used do not need extra chemical fertilizers
due to the presence of certain nutrients in
the waste water. The black and grey
waters are filtered specially for irrigation
in a way that it is partially filtered,
allowing plant friendly microbes to remain.
• The cost efficiency and fresh water
conservation because of recycling water is
significant.

13. • Important by-products like electricity and
soil amendments, are also generated
during the water recycling process. For
example, the recycled water goes through
turbines, which rotate at high speed,
converting mechanical energy to electrical
energy.
• Public areas such as parks, golf courses,
schools, and roadway greenbelts stay
green, which enhances the quality of life
for communities and cut down the amount
of pollution going into waterways.

14. multi-tasking toilet/sink
by Roca
Its perfect for small
bathrooms, and it works
on saving 25% of the
water used in sink by a
grey water self-system
and it has a trendy and
elegant unique look
Case study 1

15. Zabor’s S_basin
ecological
The water gets collected
in a tank then reused
when flushing
Case study 2

16. by Tae-jin Kim &
Design Team-IIDEA
It has a bucket
underneath it in a hole
that collect waste
water
It has a filter that gets
rid of chemicals like
soap and that grey
water can be used
again for watering
,washing rags and cars
