4                FUTURE WORKS
4.1.             PROPOSED NORTHERN PRECINCT DEVELOPMENT

The northern portion of the site is proposed for redevelopment as part of the Doonan Landfill Resource Recovery Facility
upgrade (Stage 1A). The proposed works, as summarised in Table 2, comprise a composting facility, new site offices and
amenities, internal access roads, drainage. A new a HES basin is also proposed and will discharge runoff to release point
SW2. Additional details, including detailed civil and stormwater design, are being undertaken by Covey Associates.

  ELEMENT                              DESCRIPTION


  Composting facility                  In-vessel composting (IVC) facility for green organics to be located adjacent to the RRA pad.


                                       New transfer station building with associated site office and amenities (Sherson Architecture
  Site offices and amenities
                                       concept design, 2026), public and customer weighbridges, and gravel hardstand parking.


                                       Reconfigured internal access roads and site entrance, including a 5.0 m x 2.4 m reinforced
  Roads
                                       concrete box culvert (RCBC) crossing on the site entrance.


                                       Earthworks and drainage infrastructure, including overland flow (clean-water) swales to divert
  Drainage                             external catchment runoff around the site and convey local flows, with dirty-water drainage
                                       directed to the HES basin.


                                       Type A HES basin (Covey Associates, 2026) with a surface area of approximately 2,733 m²,
  High efficiency sediment             treating approximately 6.0 ha, with optional constructed floating wetlands for nutrient polishing.
  basin                                Designed for controlled release in accordance with EA Condition WT2 (TSS not exceeding 50
                                       mg/L) at SW2.
