Abstract
Present study was undertaken to evaluate the water quality and bacteria involved in biofilm production in rain water (potable water) samples. Potable water samples were collected and assessed for isolation and enumeration of total coliforms by spread plate method and membrane filtration technique and identified by streak plate method. Through literature review and present investigation, the water samples were assessed for biofilm forming potential of water borne bacteria. Klebsiella pneumoniae was the only isolate that was successful in biofilm formation in harvested rainwater samples. Regular water quality investigations need to be approached at every secondary water storage utilities.
