Salty fogs and sand storms can result in fast deterioration of metal pipes and thus impose stringent requirements on material selection and maintenance. Therefore, the teams working on the project have undertaken a number of field trips to inspect the behavior of galvanised mild steel pipes for potable water transportation. The visits were targeted at areas surrounding Otjimbingwe, as well as Nei-Neis. Every trip is followed by a thorough laboratory examination of collected water and steel samples. The conducted tests make possible recommendations on corrosion mitigation and the optimal selection of steel grades for these severe operational conditions.
Johannes Sirunda, the Head of Research Development and Innovation, NamWater, emphasised that the purpose of this academic-industry cooperation is to ensure higher reliability and longer service life of water storage and transportation facilities.
“I wish to reaffirm our commitment to joint collaboration in research and skills development, as well as our readiness to offer solutions to the many problems plaguing the water industry,” stressed Dr Harmony Musiyarira, Head of Department of Mining and Process Engineering at NUST.
The next focus during this year, is the ductile cast iron pipeline in the Erongo Region, where cases of extensive wear and tear are reported.
