The overflow pipes should in all cases be entirely disconnected with, all drains, and the cisterns should, if possible have a cover. The cisterns should invariably be cleaned out thoroughly at least every three months.
In places where the water is drawn from wells great care should be taken that the well cannot be contaminated by any drain or cesspool leaking into it.
