Water is an essential element for life, so the ancient Civilizations were located along the rivers. Later, the progress Techniques allowed man to transport and store water, as well as extracting it from the subsoil. Thanks to this the settlements humans have spread away from rivers and other surface sources of water.
A modern water supply system consists of facilities for the collection, storage, conduction,
pumping, treatment and distribution. The collection works and storage allow us to gather the usable waters of rivers, springs and underground deposits; include activities
such as the development and care of the intake basin, wells and springs, as well as the construction of dams and galleries filters. The pipeline includes canals and aqueducts, as well as complementary pumping facilities to transport water from source to distribution center. The treatment is series of processes that give water the required quality. Finally, Distribution is to provide water to the user for consumption.
A distribution network (hereinafter will be called a network) is the set of tubes, accessories and structures that conduct water from service or distribution tanks to home intake or public hydrants. Its purpose is to provide water to users for domestic, public, commercial, consumption, industrial and for extraordinary conditions how to extinguish fires
Most of the works done in city distribution networks are to improve or expand the networks that already exist; only a small proportion are to serve new or isolated areas. By Therefore, two types of projects are required: rehabilitation and new. Rehabilitation projects are done when a part of the network must be modified to improve its hydraulic operation, or, when changes in land use or expansions in the service area force to increase the capacity of the distribution network. The New projects are required when due provide service to an area for the first time or when it is necessary to expand to a network existing, which, due to its magnitude in the project, It can no longer be classified as rehabilitation.
