      Some here may recall I was building a drip system for the garden last   
   year . It worked out well except for one problem - silt . It was   
   clogging my emitters , making it necessary to clear them frequently .   
   This year I have implemented a solution that looks very promising to   
   keep that silt out of the distribution system . I have built a "cyclone"   
   separator (got the idea from cabinet shop dust collector) out of a 55   
   gallon plastic drum . The inlet is at the top with a tee (elbow would be   
   better but I have none) with one side blocked off . This makes the water   
   swirl as it enters the drum . The outlet is about 1/4 the way up from   
   the bottom with a stub tube on it so it draws from the center of the   
   drum. The idea is that the silt is heavier than the water , and will   
   move to the outside as it falls to the bottom . So far it seems to be   
   working , time will tell how effective this will be .
