Unique Calculator for selecting the method and material of trenchless rehabilitation of gravity sewers – operational and performance benefits

A unique tool called “SELECTION CALCULATOR” will be presented of CIPP liners for trenchless rehabilitation of existing gravity sewer, combined sewer, and rainwater pipes based on the Polish Atlas of Rainfall Intensities (PANDa) program. The CALCULATOR is intended as a support tool for designers, orderers, and managers of sewer networks. It indicates the benefits of using CIPP liners/sleeves in terms of improved strength and hydraulic conditions. It answers the question of how much the potential catchment area [%] or the number of wastewater customers (p.e.) will increase after rehabilitation. At the same time, the CALCULATOR indicates which materials, with which basic technical parameters, should be used in specific cases. All are based on CIPP sleeve liners manufactured by a leading Polish manufacturer – POliner Sp. z o.o. The presentation will be conducted by experienced engineers representing one of the leading trenchless contractors in Europe – the Polish company Blejkan S.A.
