Water collection options

[Straight Shooter]

When I rerouted the spring water a few years back , I set a heavy duty plastic drum in the ground ready to act as a long term filter .....the filter drum fits inside this drum......I have gravel,charcoal and sand ready for the filter drum ....the outlet pipe is in place , but I intend to set in another collection drum a bit lower down and use that for manual easy access well .
