Treated Water Sea Outfalls for Wastewater Treatment Plants
Ministry of Energy and Water
Role of BUTEC
Scope of Work
EPC on turnkey basis including testing, commissioning and maintenance for 4 sea outfalls to discharge treated water offshore into the sea.
Although the UV tertiary treatment ensures the elimination of pathogenic agents, a model simulating the discharge dilution using CORMIX-GI was developed in order to protect the frontal coast from any risk of pollution. CORMIX-GI is a program approved by the US Environmental Protection Agency (EPA).
The simulation methodology was adopted in optimizing the proposed outfall to assure appropriate dilution rates that meet MED POL II seawater quality standards, which are consistent with the standards disseminated by the Ministry of Environment Decree (1/52).
