A safe water is one of the most important natural resources on dairy farms and needed for drinking, washing, cleaning, feed processing and grass growth. Giving dairy cattle with adequate drinking water is essential for milk production. The present study was conducted to evaluate water quality supply system in selected dairy farms in North Saudi Arabia. Physicochemical and microbiological analyses were carried out for collected water samples during the period 2018-2019. The results indicated that temperature ranged between 26.7 ± 0.10 and 29.2 ± 0.10 °C during the study period. The conductivity was highest at location-2 (0.07 ± 0.02 (ms/cm) and Location-8 (0.06 ± 0.01 (ms/cm). The TDS ranged between 411-3150 mg/L. The highest TDS value was recorded in location-8, while the turbidity was highest in Location-8 (9 ± 0.25 FTU) and Location-2 (7.0± 0.28 FTU). Calcium (Ca), sodium (Na), Copper (Cu), iron (Fe), manganese (Mn), fluoride (F), suffer (S), nitrate (NO2) and nitrite (NO3) were found in water samples with variable amounts. Bacteria dominating water samples were tentatively identified as: Aeromonashydrophila, Arthrobacter polychromogenes, Pseudomonas alcaliphila, Acinetobacter junii, Enterobacter aerogenes and Aeromonas veronii. The study concluded that drinking water of most of the tested dairy farms in the study area is suitable from chemical point of view, however, these samples contained pathogenic bacteria which may constitute health risks to consumers.
