silt in chamber dome type lines

[hockeyologist]

Has Anyone Dug Into Any Older Exsisting Field Lines To Repair Or Add On To Only To Find Chambers Filled 1/2 Full Of Silt Or Sand , Is This A Problem Only In Sandy Soils And How Does It Get There , Will Fabric Cover Help ????

Are you sure it's sand and not carry over/sludge from the tank that has dried out?
If it is sand I would assume that not enough hay or no fabric was used over the trenches.
How old of a system is it?
What State is in installed in? Just wondering if freeze/thaw is causing a problem.

I've run into several that have become filled with sand. I'm in Florida where the soil is very sandy. When the chambers are installed without cloth the sand flows through the louvres n the sides.

We are in N.E. Kansas. We sell alot of chambers to our installers. We also offer filter fabric which is required in some of the counties around us. I am also seeing washed river rock used on top of chambers and I have also seen straw used. In sandy soils you definitely need something to block off the fine silt or sand.:)
