Trenchless rehabilitation pipes system method pulling a new polymer pipe into an existing pipe and filling blank space between them

Abstract

    Today, in the modern city conditioning, water supply and sewerage systems is increasingly degraded, damaged and no longer able to ensure demand. Rehabilitation and repair water supply and sewerage systems is one of the important problem for the agency that operate on them.
