The benefits of using MDPE over copper is that it won’t corrode, meaning it is ideal for delivering clean (potable) water services. It is also inert and so has a good resistance to a wide range of naturally occuring ground chemicals and doesn't support the microbiological growth of algae, bacteria or fungi in normal operating conditions.
