Title

Developing the Performance of Sewage Pipelines Repairing Using Trenchless Methods (Case Study: Isfahan)

Pages

  18-31

Abstract

 Nowadays, the using modern Trenchless Methods for Repairing Sewer networks have been developed in most countries. Generally, for Repairing the sewage lines using Trenchless Methods, bypassing the Repair zone is necessary. For this purpose, the damaged tube is blocked upstream of the damaged pipe using plugs and packers, and to prevent rejection, the sewage is pumped to the downstream pipes. However, the pumping of sewage is a very costly task. In this study, an effective method named “ minimum pumping” (MP) is suggested using the capacity of the upstream pipes and manholes. In the proposed method, the timing needed to Repair the damaged tube can be managed in a way that the cost of pumping is reduced. Here, as a case study, sewage pipes in Nazar Boulevard and Mirzakochek Khan Boulevard in Isfahan City in Iran have been Repaired using the proposed method and the results are presented and analyzed. The results indicated that the proposed method is an effective method for reducing the cost of Repairing in sewage networks. Using the proposed method, the Pumping rate and, consequently its costs, were reduced from 35% to 50% for Nazar Boulevard Sewer network and from 70% to 85% for Mirzakochek Khan Boulevard.
