This commercial development is part of the new Sydney Olympic Park Town Centre. The project was designed in conjunction with Northrop Engineers and had to meet Sydney Olympic Park Authority water quality targets. The Vortsentry HS-12 unit was chosen to treat the carpark and roof areas of the site for its ability to enhance gravitational separation of floating (hydrocarbons and floatables) and settling pollutants (sediment). The added benefit of a small footprint and an internal high flow bypass, to eliminate washout, makes the VortSentry HS an ideal treatment option when space is at a premium.
