USAGE AND DESCRIPTION
With the constant increase of production as well as consumption of human resources, the world is facing a huge problem - where and how to discharge wastewater. This is particularly true nowadays, when the world is working hard to maintain clean environment. It has been shown that in order to achieve this, the watertight ducts are indispensable for the local or regional treatment plants. In the manufacturing of sewer pipes and fitting elements, as required by modern techniques in order to provide economical, simple and secure solutions, the use of polyethylene is irreplaceable. Pipes made of polyethylene meet all those requirements. Their use in sewer wastewater in industrial sewers (aggressive sewage), in renovating old existing sewerage network in urban centres and, of course, in renovating of dirt saturated lakes is absolutely reliable. The watertight drainage is also needed in the construction of individual houses or commercial
buildings in villages and towns. In many cases the drinking water is still pumped from wells and the sewage, which is not waterproof, and poses a major risk for the population.
