The necessary component for all life to survive sustainably on earth and every living depends on water sources for daily activity, survival, and existence. This potential source is actually becoming contaminated as a result of industrialization, and modernization of the human population causes microbial discharges and the excretion of dangerous substances. This condition causes ecological habitations to decline. This inquiry looked at the bacterial populations in soil sediment samples, water, and pathogenic (SLP and PLS) fish parts accumulation in the Pechiparai reservoir. The outcome data revealed theabundance of bacterial population about 194 ± 4 CFU/dilution of average in pre-monsoon season of soilsedimentsamplesand water (197± 2 CFU/dilution in average) over other seasons (On-monsoon and Postmonsoon). Duringmonsoonthe waterbacterialconsistency wasrefreshinghence the aquaticecosystem is balanced with both micro and macroscopic level organisms. Higher bacterial inhabitants was recorded in the surface ofNile tilapia (Oreochromisniloticus) and the isolated colonies werestudied for the identification pathogens (SLSand PLS). Differential media (Macconkey), haemolyticand biochemical characterization data revealed the presence of Bacillus sps and Staphylococcus sps. Further coliforms were enumerated in both water and soil sediments on three seasons. Among others, monsoon season exhibited predominant presence ofcoliforms around 60coloniesinwatersamplesofpre-monsoon season
