Potable Water Production Briefly about Water Intake I The
central complex for providing potable water for the city of
Subotica is Water Intake 1, since from there, depending on the
season, 75-85% of the required water quantity is supplied. Water
Intake 1 is located on the northern boundaries of the city, in
the neighbourhood of the Zorka factory, and is equipped with 29
active wells having, currently, a total capacity of ~ 350 l/sec.
The wells are drilled to about 200 meter depth and cover 2-4
aquifers. The first aquifer is at about 100-120 m depth. The
aquifers are divided by impermeable layers of clay so the
contamination of water through surface soil layers is
impossible. In case some works have been done on the wells of
the PUC (replacements of submersible pump, regeneration...),
before these are put into operation again, disinfection, flush
and the sampling of the well water are made. The wells are put
into operation only when the lab results show that the well
water meets sanitary requirements bacteriol
