Advantages of Bridge slotted water well screen Diameter is 219
1)High strength through resistance to twisting, compressive, and tensile forces
2)A smooth bore that does not impede the passage of probes, tools, etc.
3)Formations with large particle sizes
4) Large diameter wells
5)Low to medium flow rates
