Artificial filter pack is one of the most common designs used today for high capacity municipal, Industrial and agricultural wells; but before the installation of a filter pack, the contractor and the well owner must take into account some significant issues:
l The borehole must be sufficiently oversized to allow for adequate placement of the filter pack. In practice, an annular thickness of 3 to 5 in. is considered minimum.
l Often an even larger borehole is advised. The oversized borehole is costly to the contractor (and therefore to the well owner)and keeps the crew on site for additional times.
l The filter pack must be carefully selected, placed and developed to avoid bridging and sand pumping.
l The well owner is concerned with long-term performance. Biofouling and encrustation are issues that will eventually affect performance
