There are both treated and untreated sewerage outfalls in Mortier Bay where Marbase is located. The hatchery intakes will be located clear of any sources of contaminants (e.g., other outfalls, including the hatchery outfall). The outfall will be located near the surface and close to the hatchery building at a minimum of 500 metres away from other intakes.
Both the seawater entering and leaving the hatchery will be treated. The temperatures will be adjusted, and the water will be filtered and purified. Seawater leaving the hatchery will be treated to a standard that supports marine life. Regular monitoring of water quality will ensure compliance with applicable regulations.
