HSY’s stormwater sewerage area



The data contains information on the extent of HSY’s stormwater sewerage area at property level.

The stormwater sewerage area is based on Section 17 a of the Water Services Act. A property located in the stormwater sewerage area must be connected to HSY’s stormwater sewer network and HSY must provide stormwater sewerage services to the property. The material also includes areas that have a combined sewer system (combined sewerage area) as well as areas to which stormwater sewerage will be extended. The data is from 2025.

The data can also be viewed in HSY’s open data map service.
