Emisario de PEAD en tramos de 300 metros antes del hundimiento

Studies by international organizations on environmental protection, indicate that discharges of sewage into the sea through outfalls and diffusers systems represent a viable alternative for coastal cities. These systems can take advantage of natural assimilative capacity of the sea, which functions as a water treatment plant without causing any undesirable impact on seawater.

Venezuela is one of the Latin American countries with older systems emissaries have many populations located in coastal areas. He also pioneered the development of maritime sanitation plans than other Latin American countries. Howevers, most of these emissaries were built with steel pipes carbon (commonly called iron) for lack first time of a different material and subsequently due to ignorance of the benefits offered by the high density polyethylene HDPE widely used in various countries Asia, Europe, USA and South America.

This situation is history because about 10 years ago have emerged companies that have begun the installation of outfalls high density polyethylene HDPE, many, companies whose business area has been the professional diving but have made great efforts in implementing their diving techniques for the installation of this new type of submarine pipeline.

It should be recalled that the installation of outfall requires the development of a number of different activities at sea, depending on the technical requirements of each project, inherent characteristics of the installation, location, conditions, sea-weather changing , characteristics of the workboat, specialized naval equipment, crew, divers and equipment for the purpose of being able carry on the work.

Have also been developed by other companies formed by young professionals, university entrepreneurs in the installation of systems emissaries, inlets and underwater aqueducts, implementing technology and innovation by applying own engineering techniques, achieving extraordinary results in the professionalism of this area .

Thanks to these developments, the result of continuous improvement in the characteristics of an installation of subsea pipelines of high density polyethylene activities, welding termofusión exceeds all quality tests, the counterweights are becoming better designed day and optimized in the quantities required , launch systems pipeline sea are becoming simpler day and ensure less damage to the pipe and balances, maritime transportation, coupling and sinking of the sections are safer significantly reducing own occupational hazards of this kind of work . All these advances are translated into a work of higher quality, lower cost and shorter runtime.
Already there are several emissaries and underwater shots that have been built in Venezuela in high density polyethylene HDPE that have allowed the accumulation of invaluable experience that definitely marks a sure path to further progress in environmental sanitation programs coasts of our country. Already part of the past outfalls constructed in materials that offer few advantages in improving the country’s infrastructure.
