Describe the water networks in the region historically and today. How is power over water distributed in the qanat system as compared to the modern water delivery and irrigation systems? Describe the water networks in the region historically and today. How is power over water distributed in the qanat system as compared to the modern water delivery and irrigation systems?Explanation / Answer
Throughout the history, in semi arid regions ancient Persians in 1st millennium BC used qanat water supply system. Early Rome had indoor plumbing I, e a system of aqueducts and pipes that terminated in a house at public wells for the use. In ancient Peru, a system of interconnected wells and puquios was used. In Spain, acequia with sand filtration system was used. While today's water supply network includes town and municipal water supply system in different regions. Water supply system of today consists of nfrastructure that collects, treats, stores and distributes water from water sources to the consumers. Now a days 4 different types of pipe networks are used and they are - grid, ring, radial and dead end system. They are generally laid below the road pavements.
In 1st millennium BC Persians developed tunnel system called Qanat for extracting groundwater in dry mountain Basin like of Iran today. General system of Qanat included :
) Infiltration part of the tunnel
(2) Water conveyance part of the tunnel
(3) Open channel
(4) Vertical shafts
(5) Small storage pond
(6) Irrigation area
(7) Sand and gravel
(8) Layers of soil
(9) Groundwater surface
Qanat helped to reduce water loss from seepage and evaporation, though the system is entirely fed by the gravity the need of pump was not there and the rate of water flow in qanat was controlled by the of the underground water table.
Today's modern water delivery and irrigation systems includes grid, ring, radial and dead end system for its distribution and they are good and there infrastructure consists of filter portable water, stores it and then distributes it but it leads to the maximum exploitation of water which results in lower underground water table level. Today exploitation of water is enormous and people are not aware of conserving it.
