Below we present key information on our decisions for Water NSW’s rural bulk water services for customers in the Border valley. This information is not exhaustive and should be viewed in conjunction with our Final Report and Determination. 

Prices for Border valley will increase from 1 October 2021

Under our decisions, Water NSW’s prices will increase as its efficient costs are higher than those used to set prices for the 2017 Determination. The key drivers of these increased costs include that the customer share of: 

  • operating expenditure for Border valley has increased by 17.6% (but by 13.6% less than proposed by Water NSW), mainly due to increased expenditure on metering and compliance and long term transformational strategy. 
  • capital expenditure for Border valley has increased by 123.7% (and by 26.8% more than proposed by Water NSW), mainly due to increased expenditure on dam safety compliance, internal corporate projects and asset management planning. 
  • Border Rivers Commission (BRC) costs for Border valley have decreased by 3.6% and are 39.8% lower than proposed by Water NSW. 

Forecast usage volumes are also 5.9% lower than those used for the 2017 Determination, which puts upward pressure on prices. 

Offsetting these factors are a lower cost of capital, which has decreased from 3.1% to 1.8%.
