Abstract. One of the main engineering systems is the design of sewer networks in order to protect the environment and improve the quality of life of the population in order to prevent the spread of diseases that pose a threat to human health and disease. Proper planning and reliable operation of the system is considered a guarantee that the sewer system is designed correctly and modernly.
Keywords: tightness, television inspection, polymer, pneumatic, composite, fiberglass, spiral winding, dux.
