Abstract:
In Romania the irrigated surface with high economic efficiency it is
estimated at 3,5 mil. ha. On national scale there is no integrated approach of
the quantity and quality values of the irrigation water, as a resource, as well
as an equipping of the pumping station. On international scale, in the
developed countries the pumping stations are provided with equipment for
monitoring, on real time, the quality or the pumped water and with for
warning about critical situations (emergencies).
The technical solution consists of an equipment which monitors the
following parametres: turbidity, pH, CE at 250C, Na+, Cl-. The lapse of time
for monitoring is of 10 – 60 min. The main components are the following: the
prelevation pump (submersible) the monitoring board, the repression pipe of
the analysed water. There are made warnings about tue exceeding of the
programmed level for each monitored parameter, about tue fact that the
pump and agitator don’t work or about any other source of damage.
The testing of the equipment in the ground was made at the base
pumping station Manta, from the Danube Meadow, Giurgiu county.
The water is from the Danube and it is in most of the cases mixed with
the water originating from drainage mixed with the drainage water.
The economic effects of the solution consist of the following issues:
the decrease of the total content of soluble salts from the soil; the removal of
the negative impact of the mineralized water upon the production level; the
decrease of the alluviation degree of the irrigation arrangement site; the
increase of the economic efficiency of the irrigation by including the water
quality on the price.
