Water Supply Agreements


Cascade's wholesale water supply agreements.

The Seattle wholesale agreement entitles Cascade to a specified amount of water each year for a fifty-year period ending December 31, 2063. The agreement extends current capacity of 33.3 mgd through 2039 and then ramps down throughout the remaining years.

In December 2012, a new contract was signed with Tacoma, which restructures the prior Tacoma supply contract and clarifies Cascade’s rights and responsibilities for the previously purchased capacity to enable and transfer to specific third parties through a joint offering. Under the new contract, minimum water purchase volumes have been replaced by a structured capacity reservation schedule and a new capacity commitment of 8.0 mgd provided to Cascade through 2042.
