The Twentysixth Street environmental watering site is located at the end of Twentysixth Street, not far from the Nelwart Street site, which is coloured orange on the map. In 2016, the site was dominated by black box trees, lignum, nitre bush, and samphire. The first watering occurred in 2017.
By 2020, the retention of water at the Twentysixth Street site over successive watering years encouraged a group of swans to nest. There was also a notable increase in native duck species and other birdlife at the site. Native grasses have also grown back and line the environmental watering site.
