I understand the risks of sharing water.
I use rain water for my orchids and after one unusally dry summer by the end of autumn I was really running low on rain water so I grouped plants together. I figured there was less risk sharing between the plants that had grown together for several years than subjecting them all to the rigours of town water.
I put maybe half a dozen in each group and shared water between them. I figured if anything were to happen at least it would be restricted to that particular watering group.
As soon as my water supply was restored I went back to individual watering but I would do the group watering again if needed.
