Foot traffic, car parks and loading areas in Chatswood
Retail and office buildings near the station see heavy foot traffic all day, so washing is often done before opening, late at night or on quiet weekends. Plazas and paved concourses hold chewing gum, food spills and grime from shoes, while basement and podium car parks collect oil and brake dust that standard sweeping does not remove.
Loading docks and bin areas bring grease and food waste, and they need controlled wash water. In residential streets, mature trees and shade encourage mould on driveways and walls, while higher density areas have shared driveways and strata common property. Both need a clear plan for water, noise and access before a start is agreed.
