    • Treatability study for identification of the optimum wastewater treatment alternatives:
      • Comprehensive sampling and analysis campaign representing the variable discharge schedule.
      • Identification of WW flow rate at the main discharge points.
      • Documentation of the activities, experimental tests, and calculations.
    • Prepare basic and detailed designs of the WW Management Scheme, followed by preparation of tender documents for constructing the WW plant and evaluation of the bidders.
    • Supervising the construction work.
