There will not be any impacts to rates in 2017.

The estimated cost to design and construct filtration is between $350 and $500 million. As is the case with large capital projects such as this, decisions on matters such as treatment method, size of plant, construction timeline, and other major decision points throughout the 10–12 year project will narrow specific cost estimates as planning and design continues.

Using the most expensive cost estimate of $500 million, bureau modeling shows:

 

In Year 1 (2018)

In Year 10 (2028)

In Year 15 (2023)

For the average bill,
filtration will raise rates
each month by...

$0.82

$12.55

$15.24

Again, please note that the impact-to-ratepayer estimates above use the most expensive design options and most conservative financial assumptions. They also exclude any rate stabilizing efforts or cost offset programs. Estimates represent the highest possible cost scenario and are expected to come down.
