The North Heatherton Wetland renewal project was undertaken to revitalise the wetland, with the overarching goals of restoring stormwater treatment capacity to achieve approximately 2.5 tonnes of nitrogen removal per annum, and improving accessibility and safety in order to support the ongoing maintenance of wetland assets.
The Touch Projects team provided project management services to Melbourne Water, working closely with the service provider to ensure the project was delivered in alignment with strategic goals, operational requirements, and safety for both workers and the wider community.
As part of the project, the wetland basin was reshaped and shallowed to encourage the growth of ephemeral plant species. This was with the intention of improving biodiversity and water quality.
Topsoiling works were also undertaken on the wetland cell, and erosion control matting was installed.
The wetland’s control pits were renewed in order to enhance infrastructure performance in future.
Finally, revegetation was also undertaken to help support local habitat and ecological restoration within the wetland.
A major focus of the project was sustainability and the achievement of positive environmental outcomes. By reusing wetland sediment and limiting the removal of green waste, much of the existing habitat was retained, supporting local fauna and ecological resilience.
Touch Projects, in collaboration with Melbourne Water, ensured that the project was completed on schedule, under budget and to a high quality. The renewal project also delivered improvements in safety and environmental performance, setting a strong precedent for future wetland renewal initiatives.
