Water Quality & Efficiency
Stormwater Quality
Intent
To protect water bodies from degradation due to the impacts of urban activity.
Requirements
Ensure the removal of 80% of Total Suspended Solids from runoff leaving the site.
Stormwater Quantity
Intent
To promote infiltration, and evaporation. Providing more resilience, reduce risks of flooding/erosion, and reduced demand on water treatment plants.
Requirements
Retain runoff volume from the 10 millimeter rainfall event on site.
Rainwater Harvesting
Intent
To reduce potable water use for irrigation and interior building functions.
Requirements
Designed and constructed building for rainwater re-use for low-grade functions, AND reduce potable water used for irrigation.
Water Efficient Fixtures
Intent
To reduce potable water use for building functions.
Requirements
Install water fixtures that achieve a 40% reduction in potable water consumption for the building (excluding irrigation) over baseline fixtures.
