16S rRNA gene amplicon sequencing data from an Australian wastewater treatment plant

Amplicon sequencing data of the 16S rRNA (V1-V3) gene from 56 effluent and sediment samples from an Australian wastewater treatment plant are reported. Proteobacteria (3.50%-90.09%), Actinobacteria (0.02%-45.71%), and Cyanobacteria (0.05%-63.73%) were dominant in the effluent. The sediment samples were dominated by Proteobacteria (13.14%-84.83%), Chloroflexi (0.84%-42.52%), and Firmicutes (1.54%-17.21%).
