World over, drains are the main source of water pollution especially for rivers flowing within the city. These drains generally carry industrial effluent, domestic waste, sewage, and medicinal waste results in pooring the water quality. The extent to which these drains pollute the water quality of river Gomti in Lucknow city is not well documented yet. The present study thus evaluates the effect of 26 drains on water quality of river Gomti in Lucknow city, which submerged from cis side (14 drains) and Trans side (12 drains). For this, 13 necessary physico-chemical parameters from all drains were estimated as per standard methods and evaluated statistically. The results revealed that most of the indicator parameters are above the permissible limits of BIS and WHO standards. The mean level of total solid, total dissolve solids, total suspended solids, conductivity, and sulphate at trans side was found to be significantly higher (p<0.05 or p<0.01) than the cis side. Among drains, the kukrial drain (mid of the city) is the highest polluted drain while Gaughat the least (upstream). The higher level of pollutants polluting the water quality of river Gomti, disturbing the ecology of river and affecting human health directly and indirectly.
