  • Section 8: Gravel Filter Pack - Lifewater Canada

    2019-8-15  A filter pack is coarse sand or fine gravel (2-6 mm diameter) that is placed between the borehole wall and screen (see Section 9 - Figure 15).Filter packs are used to settle-out fine grained particles that may otherwise enter the well and to increase the effective hydraulic diameter of the well. A filter pack is like a wells "lungs" passing water to the "heart of the well" (the screen).

    What does mesh size mean? Figuring out mesh sizes is simple. All you do is count the number of openings in one inch of screen (in the United States, anyway.) The number of openings is the mesh size. So a 4 mesh screen means there are four little squares across one linear inch of screen. A 100 mesh screen has 100 openings, and so on.
