The research of hydraulic properties of pipes to be relayed in repair bays or to be no-dig recovered is a constituent part of renovation approach. The designers do not have any information on hydraulic properties of new protective materials and have to use the hydraulic calculations procedures, strength and hydraulic data submitted by pipe manufacturers that may not be regarded as objective arguments towards selection of pipeline material. Role of experimental hydraulic studies is increasing therewith. One must have information on hydraulic properties of both pipes and repair materials (e.g. polymer covering, new types of polymer pipes, etc.) to analyze the situation. Two polymer pipes that can be used for trenchless renovation are considered and analyzed: corrugated polypropylene pipe DN 98 and bare pipe DN 105 made from unplasticized polyvinyl chloride. The experimental results to fix relative roughness factor are presented and analyzed in this paper.
