Bridge slot screens have openings arranged in rows and are staggered to reduce the
negative effect on the screen's strength. Typically the slots are punched in a flat sheet
that is subsequently rolled into a tube and welded. Advantages offered by this type of screen are:
•Between 0.5 mm / 0.002 in. and 5mm / 0.2 in., depending on the wall thickness

aquifer and are regarded as a profitable mode of obtaining water.
------reducing the water velocity(V1>V2)
------reduction of pressure fall
------Reduction of the head loss(R1>R2)
------higher flow rate(HMT1>HMT2)
------no sand in water
------prolonging the life span pumps
