hi
just buying a poly tunnel . want to use the tunnel to gather rainwater using the sides of the tunnel to collect water via a gravel bed system in to a storage tank  .any ideas on filters to stop the system clogging with silt when i use a sprinkler system
thanks dave

Not for this method but I have seen people who suggest fitting guttering halfway down the side (google polytunnel guttering uk for a example)
