Abstract: During the study period (1999-2001) thirty parameters were analyzed and an average of six determinations were examined. Transparency was in the range of 4.42 to 13.42 cm, dissolved oxygen was absent at all sampling stations, biological oxygen demand (BOD) 177 to 367 mg/L, chemical oxygen demand (COD) 312 to 648 mg/L, total nitrogen 12.8 to 33.94 mg/L and total phosphate 2.6 to 7.19 mg/L. Inorganic pollutants: chloride, total residues, total filterable residues and total non filterable residues were calculated. The average metal ions sodium, calcium, magnesium and potassium were observed in the range of 98.7 to 314 mg/L, 59 to 148 mg/L, 30 to 81.6 and 23.4 ?? 56.8 mg/L respectively. SAR values were calculated in the range of 2.47 to 5.3. The total quantities of wastewater discharge from Hyderabad city areas were calculated to be 103235 m³/day. The results indicate 26.949 ton/day (t/d) of chloride, 0.467 t/d of total hydrolysable phosphate, 2.433 t/d of Kjeldahl nitrogen, 152.024 t/d of total residues, 144.988 t/d of total filterable residues, 36.105 t/d of non filterable residues, 17.302 t/d of sodium, 8.511 t/d of calcium, 4.917 t/d of magnesium and 3.466 t/d of potassium.
