The South Coast Sewage Treatment Plant is responsible for treating all sewage from the south coast sewered network before it can be disposed of through a piped outfall, into the marine environment. The plant consists of varying screening elements that remove debris and solids from the sewage flow. As sewage flows through the plant, varying levels of hydrogen sulfide (H2S) gases are released into the plant. These H2S gasses are highly corrosive, and have caused the degradation of numerous doors as well as door jambs of both the treatment building as well as the administrative building at the facility.
- DESCRIPTION OF WORKS AND SPECIFICATIONS
- Single and Double Doors
- Supply and install all doors significantly impacted by corrosion, with new or doors
constructed from grade 304 or 316 stainless steel grade or other material suitable for use in corrosive wastewater environments.
