Rivers-streams in Attica-Athens
Attica does not have big rivers or lakes. There are :the seasonalKiffisosRiver which flows through western Athens, the Ilisos River which crossed the eastern half of Athens and the ancient river Iridanos.
In the past there were a lot of streams but today there are only 70
The streams have been covered , built without fixed planning and turned into rubbish dump .
The result is that regions round them have flooded and human lives have been lost

Benefits of city from the streams.
1. They create a park in the city , offering a green belt lacking in the urban environment , thus providing space for entertainment
2. They regulate the microclimate of region. Thus the summer becomes cooler and the winter milder.
3.Streams collect rainwater ,channel them to the sea and floods are avoided.
4. They renew the air of the city and help the pollutants to be scattered .
5.Streams clean the atmosphere because the vegetation absorbs dust, pollutants.
6.They offer sound insulation because the vegetation of the area absorbs the annoying noises of the city.
7.They improve the dull urban landscape

Kiffisos and the area around it.
A lot of industries function in this area. In the last 50 years industries continue to emit their waste in the river .
In the previous century the area around the river .
The urban development of Athens in the 20th century, the covering of many streams and their transformation in road axes has resulted in the flooding of Kiffisos.
Ilisos : famous river in antiquity
Athens and Ilisos river in the Hadrian’s period (Roman Emperor 76-138 a.c.). Woodcut
The god Ilisos is depicted in the right end of the western pediment of Parthenon.
In the past
During summertime Ilisos was dry and turned into rubbish dump
It was decided to be covered and became street.
Works started in the previous century and finished many years later (1965)
Iridanos : Ancient river of Athens. Sprang from the Lykavitos hill and crossed the historical centre of Athens.In the 5th century b.c the river was covered and changed in underground river.The watercourse of river was found after excavations.
Parts of the watercourse exist in one of the metro stations

The circle of water in Athens.
In the past and in the present.
Athens has always been an area with little rainfall, and consequently, water resources have always been scarce. Thus, from the very beginning, its inhabitants had to develop basic water collection and distribution systems for the water supply of the city. These systems gradually improved with the passing of time and the progress of technology.
Ancient Athens was primarily supplied with water from springs and local wells.One of the most famous natural springs was the Spring of Caliroi (the source of the Ilisos River).
A local well
The first water supplying structure in Athens was built in the Roman period and more specifically in 140 A.C. from the Roman emperor, Hadrian. It was then when the Hadrian Aqueduct and the Hadrian tank were built. The Hadrian Aqueduct began at the foot of Mount Parnes, in the area of Tatoi and transported water by gravity to a stone reservoir on the hill of Lycabettus in the city of Athens. There, the Hadrian tank was built, in which the water was stored. Parts of the water supplier still exist, as well as the one in Kolonaki (area of Athens). In this way the city was provided with water until the Turkish occupation.
During the Turkish Occupation the Hadrian Aqueduct and the Hadrian tank were abandoned and so the people of Athens were again supplied with water from springs and wells. Parts of the Hadrian Aqueduct and the Hadrian tank were cleaned and started working again in 1840 , which is after the Greeks gained their freedom again from the Turks. In addition there were people who transported water from springs. But the population of Athens increased continuously and the problem of insufficiency of water was intense. It is obvious that the above-mentioned ways of water supplement were insufficient to cover the capital’s needs.
In 1925 a contract was signed between the Greek Government, the Bank of Athens and the American Firm ULEN for the financing and construction of the new water supply works.The first major project was the construction of Marathon Dam (1926-1929) with a total height of 54 m. and a length of 285 m.

How is Athens supplied with water today?
The water reaches to Athens from the aqueduct of Mornou crossing a distance of 192 kilometres.
How much water we consume
We fill a tea-kettle... we use roughly 2 litres water
We take a shower... we use roughly 25 litres water
We wash the clothes in the washing-machine... we use roughly 60 litres water
We wash dishes... we use roughly 5 litres water
Each time we use the toilet cistern we spoil 10 litres water
On average, a person uses 160 litres water each day
A medium house needs roughly 3500 litres daily
