Sohar Industrial Waste Treatment Facility (IWHTF)
TerraConsult, a wholly owned ByrneLooby company is the lead landfill design engineer for the Sohar Industrial Waste Handling and Treatment Facility (IWHTF), one of the world’s largest hazardous waste management facilities being developed by Oman Environmental Service Holding Company (Be’ah). Our primary role was to provide detailed designs and construction support for three new landfill cells and to design the 400,000 m3 earthworks for a 30-hectare development platform.
The photo illustrates the June 2018 state of construction of the double composite lined hazardous waste cell on the IWTF complex. There are 8 geosynthetic layers in the engineered containment lining system, including 2 sets of HDPE/GCL, drainage and protective geotextiles.
This landfill is one of three being constructed, which will provide 18 million m3 of void space on the complex, in accordance with a 30-year masterplan prepared by TerraConsult for Be'ah. The photo shows the first cell of the hazardous waste landfill; there are separate non-hazardous and inert waste cells constructed on other parts of the site.
The TerraConsult brief on this Design & Build contract included tender support, site investigations, environmental monitoring, hydrogeological studies, facility master planning, earthworks design, landfill design, geosynthetics design, surface water management design, site-based construction support (including CQA) and preparation of the operations, environmental monitoring and closure plans.
