Just a further couple of points to add about above ground
pipes:
1. They are vulnerable to both sabotage and theft hence my comment above about engaging with
the communities across whose land the pipeline crosses. If they are able to benefit then they are
likely to look after and watch over the pipeline. Hence, something to consider in the design are tap
points along the route serving potential users, either domestic supply or animal watering.
2.
Be very careful when commissioning the pipeline. Catastrophic failure of joints can occur when a very
hot steel (or plastic) pipleine is suddenly filled with cold water. Choose the time of day, or night,
to commission gradually and monitor closely.
