Pinyari (old Phulleli) canal off-takes from left bank of Kotribarrage is last Hydraulic structure on Indus river. This canal is passing from periphery of Hyderabad city and its design discharge is 13,636 cusecs which supplies fresh water not only for agricultural, industrial purpose and drinking purpose for the several towns and villages because groundwater in its command area is highly saline and not drinkable. The cottage factories and Hyderabad industrial area are located on nearby banks of canal. Hence, effluents from city and industrial SITE area are directly disposed off into the canal. The disposal of untreated wastewater created health and environmental safety problem. This paper presents that the analyzed results of water quality parameter ie pH, TDS, EC, Na, hardness, K, Mg, Mn, DO and BOD of collacted samples exhibit TDS 6%, K 20%, DO 67% and BOD 54%, respectively exceeded permissible limit. While pH, Na, hardness and Mn found within prescribed limits. Total coliform /E.coli (MPN/100ml) were found positive. Furthermore, the result of Water Quality Index (WQI) model reveals that water quality of canal of collected samples varies from excellent to very poor that reveals canal water is unsuitable for drinking purpose and aquatic life and also causes various waterborne diseases.Therefore, the local people are facing serious health problem by consuming water canal. With an attempt to ensure enforcement of environmental water laws in Sindh province of Pakistan for preventing degrading clean water. These environmental water laws have already been framed, but due to lake of enforcement, water pollution problems are increasing day by day. The enforcement of environmental water laws are very essential to control water pollution for safety of human health, and ecology in Sindh,Pakistan.
