Raw reads from three drinking water treatment works at stages raw water, DAF slude, clarified water, RGF media and filtered water
DNA was extracted from samples at multiple timpoints throughout the year at three water treatment works in Wales at various stages from raw water inlet to filtered water after rapid gravity filtration. Reads are 16S rRNA metabarcoding sequences using the V3-V4 region, sequenced using the sequencing platform Novaseq 6000 SP.
