How Rates are Determined

Water and wastewater rates are influenced by a wide variety of factors, from the cost of maintaining and replacing pipelines to the energy involved in moving water throughout the system. While the District has worked hard to keep rates low by maintaining lean staffing levels, centralizing operations on 1 site and bringing a number of key proactive maintenance measures in house, the costs involved in purchasing, pumping, treating and delivering water is on the rise.

In order to identify the exact costs impacting their customers water bills, the District commissioned a detailed cost of service analysis by independent financial experts.

This study identified a number of key factors that are driving rate increases:

  • Rising treatment and energy costs
  • Impacts of regulation and legislation
  • Conservation measures
  • Need to rehabilitate additional water storage for reliability
  • Need to perform critical upgrades and replacement to the water system
