Abstract
In Victoria, Australia, occasional pH increases in drinking water in Yarra Valley Water's distribution system occur as a result of the combination of low-alkalinity water and cementitious pipes.
Significantly elevated pH (above 9.2) is experienced only in isolated locations with low turnover (estimated at approximately 0.2% of the distribution system), with maximum reported pH values of 10.3.
A study was conducted to quantify the upper bounds of pH experienced in the utility's distribution system and obtain evidence to inform the assessment and management of pH through operationalizing the water safety plan.
