Present study was conducted to check the feasibility of industrial reclaimed water (IRW) for irrigation purposes and its impact on plant growth and soil properties. Different types of grass, shrubs, ground cover and trees were grown in three experimental plots. Each plot was subdivided into three subplots for shrubs, ground cover and trees. Plot A was irrigated with industrial reclaimed water (IRW), plot B with (50/50) mixture of both IRW and treated sewage effluent (TSE) and plot C with TSE. Results showed that IRW is highly saline with high sodium (914 mg/L), SAR (42.8) and TDS (3054 mg/L) as compared to TSE (Na 220 mg/L, SAR 8.6 & TDS 1081 mg/L). Plants irrigated with IRW and mixture of IRW and TSE (50/50) indicated mortality rate of 57% and 12% respectively, while plants irrigated with TSE have only 4% mortality.
