ATHENS

40. 5 th century BC

41. WATER SUPPLY OF
ATHENS
• Throughout its long history, the city of Athens
had to deal with the same problem. Water
scarcity.
• The water supply of Athens was mainly achieved
through wells and springs.
• There were many fountains scattered
everywhere in the city, but many rainwater
reservoirs as well.
• The most famous ancient aqueducts were the
Pesistratus 530 bc and the Adrianon 134-140ac.

42. WATER SOURCES FOR
ATTICA. CAPACITY OF
RESERVOIRS
• The Dam and lake of
Marathon with
average capacity of
14.400.000m3 per
year.
• Natural lake of Yliki
with average capacity
of 600.000.000m3 but
13 is lost to ground
drainage.

43. WATER SOURCES FOR ATTICA.
CAPACITY OF RESERVOIRS
• The Dam and lake of
Mornos with average
capacity of
210.000.000m3 per
year.
• The Dam and lake of
Evinos with average
water capacity of
220.000.000m3 per
year.

44. Water Sources
Evinos Mornos
Yliki
Marathon

45. WHAT IS THE WATER QUALITY OF
THE WATER SOURCES? IS IT
DRINKABLE?
• The water of the four
large lakes that supply
Athens, must go through
the water treating plants,
where it is cleaned and
disinfected.
• The water net of Athens
today is drinkable and of
excellent quality,
considered among the
best in Europe.

46. BOTTLED WATER.
WHAT IS THE STORY IN
GREECE
• Greece is among the top
10 countries in Europe
with the largest bottled
water consumption per
person.
• The largest consumption
is taking place in the
summer. In areas with
bad quality water,
people drink bottled
water throughout the
year.

47. ALTERNATIVE WATER
SOURCES
• Reuse of treated household
water from daily activities.
• Desalinization.( extract salts
from sea water)
• Reusage of treated sewage
system water.
• Small and medium size
systems of collecting and
storing water.
• Water flow in drainage areas
and the replenishments of
underground water horizons.

48. SEWAGE WATER TREATING
PLANT
• Psitalia is a small island of the
Saronic gulf, between the harbour
of Piraeus and the island of
Salamina. An area of 0,375 km2
with no permanent residents.
• On the island you find the largest
sewer system treating plant , with
incoming sewage flow of
730.000m3 daily.
• This plant was the main factor for
the great improvement of the water
quality of the Saronic gulf, and the
improvement of the quality of life of
the people living in the nearby
areas…..
