Abstract:

The increase in pipe roughness and loss in carrying capacity for water mains carrying high pH water is documented with over 20 field tests conducted in Austin, Texas. The data show that the rate of growth of pipe roughness decreased once the Utility began to add scale inhibiting chemicals to the water.
