The article discusses the causes of accidents in water supply and sanitation systems. methods for improving the quality of drinking water in the construction and reconstruction of water pipes, the use of new materials to reduce breakdowns on networks are considered. the analysis of the durability of pipelines made of various materials is carried out, according to which it is concluded which material is the best in use for installation work. frequent destruction of pipes occurs from an aggressive environment, so a comparative analysis of various materials from which they are made: polyvinyl chloride, polypropylene, reinforced concrete, cast iron and fiberglass. due to poor-quality cleaning, there are environmental problems that occur when using old structures, lack of funding. It is concluded that fiberglass pipes can serve as a high-quality material.
