Point source discharges to marine waters

Water quality data is collected inside and outside the mixing zones at each of 18 ocean outfalls along Victoria’s coast but reporting and analysis are limited. However, reports submitted to EPA indicate that each outfall is meeting its licence conditions. Although there have been overall improvements in the quality of stormwater discharges to Port Phillip Bay, there is limited data on individual discharges.

Reported as volume by treatment category (primary, secondary, tertiary)
