Wholesale Water Information

Tacoma Water serves 15 wholesale customers in the Puget Sound region. While wholesale customers generally have their source of supply, there are a few reasons why wholesale customers elect to purchase water from us. They might:

  • Rely on an additional source of water supply.
  • Want redundancy.
  • Need an emergency supply.

Alternative Options

We seek to increase engagement with our wholesale customers and provide options that are responsive and unique to their individual needs. If you are interested in exploring alternative wholesale water options, we will work with you to determine the most suitable path for your situation. Alternative options include:

  • Market-Based Pricing that enables you to pay a different rate from the published rates. We generally base the methodology on an assumption of competitive alternative sources of water supply and establish a relationship between the quantity of water you need and the price you pay. Specific pricing terms depend on the total quantity of water and the seasonality of the amount.
  • Reverse Capacity Authorization (RCA) enables you to opt-out of our monthly fixed charge for each month that you do not choose to receive water. We calculate RCA by amortizing the capacity we contract for over 30 years. Amortization provides flexibility to plan for buying water while allowing us to mitigate supply risk gradually. We are currently in the process of developing the mechanics of this platform and drafting an addendum to the existing wholesale water agreement.
