In 2014, Tunacor Fisheries Limited (Tunacor) became 100% wholly Namibian owned fishing company from its predecessors South Africa and Spanish management. It was in 1958 that Tunacor was first established as a business infrastructure solely focused on Pilchard Cannery and Fishmeal. Over the years the company has grown and transformed into processing and the exporting of value-added fish products directly to retailers locally and international markets. The fishing factory currently employs over 2100 people and has a fishing fleet of 12 trawlers and 3 long liners. Due to the growing increasing demand in water supply services by the Walvis Bay Municipality to the residents and industry, the fish processing industry is faced with the challenge to consider alternative and efficient water supply sources required for cleaning purposes in fish processing factories as opposed to using municipal potable water for this purpose. Tunacor currently abstracts about ± 407 000 m³ of seawater per annum that is used in the fish processing factor for cleaning purposes only. About 101200m³ of potable water per annum supplied by the municipality is also used in the fish processing factory and other facilities. The abstracted seawater is treated through the already installed Water Treatment Facility prior to usage in the factory. An effluent’s discharge filtering and screening system has been installed to ensure further screening of the resultant waste seawater from the fish processing factory to enable the collection of fish solid waste that is used as part of the fishmeal processing. This avoids further discharging of the solid material into the sea. Tunacor further undertakes qualitative monitoring and analysis through a certified lab Namibia Standards Institute (NSI). This is done to ensure the discharged waste sea quality is within the criterion used for the discharging of waste seawater at sea. However, there is potential impacts that may be associated with the marine ecology that Tunacor has not identified yet through the existent operational activity of seawater abstraction and wastewater discharging at sea. The proposed EIA process including an assessment and compilation of an environmental Management Plan will allow an opportunity for identifying the aspects and impacts, and document the proposed management and mitigation measures for implementation. This process will then proceed to an application for a seawater discharge permit with the MAWL after the MEFT has approved and issued the ECC. the ECC is required for the continued operation of the water treatment facility and discharge of waste seawater at sea.
