Protection systems comprised of drainage canals and pumping stations protect low-lying farmland in the vicinity of Iron Gate 1 and Iron Gate 2 HPP’s from the adverse effects of their reservoirs. These systems evacuate drained water and precipitation from the protected area. The pumping stations maintain groundwater levels at pre-defined elevations.
Monitoring of the impact of the reservoirs and of the performance of the drainage system had revealed sub-standard operation of certain pumping stations; that is, their inability to maintain required water levels in the delivery canals. This directly impacted water levels of the entire canal network, as well as the groundwater regime in the protected area.

 

 


Measurements associated with individual pumps and pumping stations, covering their entire operating range under given hydraulic conditions, needed to be conducted in order the determine the actual capacity and condition of each pumping station. The data were analyzed and used to determine whether and to what extent performance deviated from design criteria, and to identify any measures needed to improve efficiency.
To determine the capacity of each pump, it was necessary to:

  • Determine the Q(H) function based on flow and pressure measurements at the point of discharge;
  • Conduct overall flow measurements and determine the Q (t) function at the common discharge pipe while all the pumps were in operation;
  • Conduct flow measurements using an alternate measurement method or a different instrument;
  • Measure pump power over the entire operating range; and
  • Measure water level variation at the intake basin, Z (t).


Measurements were conducted at four such pumping stations.
Different flow measurement methods were used, depending on the type of pipe and the prevailing hydraulic conditions:

  • Pressure pipes: ultrasonic flow meter Krohne UFM 640P (transit time)
  • Non-pressure pipes: ultrasonic flow meter Nivus PCM Pro (Doppler)
  • Discharge pipes: electromagnetic probe (single-point velocity and velocity profile)
  • Where none of these methods could be applied, a physical model was built at JCI to derive the Q-H curve.
