Water intake from underground sources

The composition of the water intake and their General arrangement

Off-site water supply systems from groundwater sources consist of:

rainwater (meter) facilities for water intake, water wells (aquifer);

pumping stations of the first lift of water-meter devices;

prefabricated culverts that collect water from meter devices and conveying this water to the water treatment system (if necessary to improve water quality) or feed it in tanks for subsequent transportation to consumers;

facilities for water treatment and advanced water treatment to the required quality;

pumping stations and main conduits for transporting water to the consumer;

structures automation to regulate pressure and flow of water before supply to consumers in the internal network.

This is a typical scheme of functioning of groundwater abstraction. Rainwater (or meter) devices are drilling wells for water. The scheme, as well as the presence and mutual arrangement of the individual components thereof, may vary somewhat depending on hydrogeological conditions in a particular locality (presence of aquifers, quality of water, capacity of water intake), distance of source of water supply from consumers and the number of the latter; and from other possible conditions.

The underground water supply of Jerusalem

Underground water facilities in Jerusalem is a special milestone in the history of the development of the city of David. Initially, residents used a single source called the Gihon outside the city walls. So during the siege, residents were left without water, the source is carefully disguised, and the rock struck the tunnel where the water was going into the city.

The Gihon spring was distinguished by one feature: it periodically with the difference of a few hours threw the water fountain, and the citizens had to figure out how to collect water and supply it to the consumers. Archaeologists have long explored the underground hydro-technical constructions, created by ancient inhabitants of Jerusalem to collect the waters of the spring Gihon.

The Aqueduct Of Hezekiah

During the reign of Judean king Hezekiah from Gihon to Siamcom pond was built a tunnel length of about 600 meters. The tunnel passed under the city walls, directing water source to the pond located within the territory of the city. Traces of ancient constructions are still visible today. Tourists visiting the country of the Jews, to lead tours of the “water of Hezekiah”. It is noteworthy that the tunnel was quite sophisticated for their time engineering work. Continue reading
