a fire hydrant.
The implications for diarrhoeal and other waterborne illnesses for areas where large numbers are dependent on public hydrants is therefore very serious.
Within the piped category, both individual connections and public hydrants are included.
First, hydrants were of a type designed to prevent freezing by allowing drainage of water after use through a riser drain port.
As mentioned earlier, the proportion of samples failing to pass the laboratory tests is very similar for public hydrants and individual connections.
In the case of legal piped water supply, for both individual connections and public hydrants, the picture is reversed with failure rates ranging from 31.6 to 37.5 per cent.
For colonies where community level water sources (for example public hydrants, community handpumps) were being accessed, all the specific points that were being accessed by the surveyed households were sampled.
Water and swabs were sampled from these hydrants and from water blasters but yielded no legionella.
The data here reveal that about 70 per cent of households using either individual piped connections or public hydrants are subject to interruptions in the water supply.
