This project is designed to establish exactly what we can allow over our pressure mains and what our true minimum cover requirements are.
We will need to test all legacy pipe types currently in operation – i.e. asbestos cement (AC), cast iron(CI) and cement lined mild steel (MSCL).
Of these pipe types, we will need to test a number of different ages and sizes, from 100mm up to 1400 mm for some types, in both full and empty condition.
The testing must include static loading to exceedance of allow deflection limits / destruction and dynamic loading to represent that currently provided by typical modern earth working plant.
