SPR technology

A series of difficulties and problems were encountered by us during the execution of the contract \"Renovation of the existing sewage networks in the left riverbank of Szczecin\", and we have already written about some of these stories in the columns of this quarterly in preceding articles. The sewers were renovated by us using various technologies, including CIPP liners, discrete pipe liners, chemically resistant coatings, open pit pipe replacements, and pipe eating.
