Stormwater Treatment Measures

A treatment-train approach to stormwater management involves a range of measures (primary, secondary, and tertiary) that work together to enhance water quality.

1. Primary Treatment

Remove gross pollutants

2. Secondary Treatment

Remove fine particles, sedimentation, & attached pollutants

3. Tertiary Treatment

Remove very fine/colloidal particulates, dissolved nutrients, & heavy metals

4. Back to Environment

Clean, treated water flows back to the environment

Gross Pollutant Traps - Primary Treatment

The aim is to remove gross pollutants and coarse sediment (>5mm in size) and help in the downstream treatment of smaller pollutants.

Tertiary Treatment

Tertiary treatment is the final cleaning process that improves wastewater quality before it is reused, recycled or discharged to the environment.

The treatment removes remaining inorganic compounds, and substances, such as the nitrogen and phosphorus.

Bacteria, viruses and parasites, which are harmful to public health, are also removed at this stage.
