Abstract:
Fuleli canal takes off from river Indus from left bank of Kotri Barrage and passes through Hyderabad city with a population of about 1. 7 million. Most of municipal and industrial effluents of Hyderabad city are added to Fuleli canal during 14 k. m. A number of sampling stations, six from Fuleli canal and five from sewerage and industrial effluents have been selected. Eight samples were collected from Oct. 1992 to August 1993. The samples were analysed for conductivity, transparency, residue (total, filterable, nonfilterable, fixed and volatile) and chemical oxygen demand. Total residue were found in the range of 320-1750 mg/liter in Fuleli canal and 880-2850 mg/I in sewerage water. The volatile fraction in total residue in Fuleli canal was 35-240 mg/I as compared to 160-880 mg/I in sewerage water. The chemical oxygen demand (COD) was 12-223 mg/I in fuleli canal and 150-1796 mg/I in sewerage water. The results indicate that sewerage lines are highly loaded with residue and have pronounced effect on the COD of Fuleli canal.
