The SIMS data source

EnviroSite information is collected from a database managed by The City's Environmental & Safety Management (ESM) business unit. This database is named Site Information Management System, or SIMS, and is the single source for the historical site information as well as the environmental report information. SIMS also provides the landfill information provided in EnviroSite's colour map.

Access to SIMS data

The City Online subscription service is the only method for obtaining information from SIMS. Direct requests for environmental site information sent to The City will not be completed. For more information on Cityonline

Data updates
