Water is the most important element for life, i.e., for humanity.
We have currently $2\times200+380=780$L storage capacity for Sotito's garden. We aim to replace our propane deposit with a water one to increase that and collect the huge surplus of water in winter time. Options are from dk or from aquaenergy (horizontal) and in ground.
We also have a leak of ~50L/day which we are actively looking for.
