Wyoming Public Service Commission

Water Utilities

The Commission regulates eight water utilities that provide retail water service to Wyoming customers.

The PSC has the following primary duties regarding the regulation of natural gas utilities:

Hearing rate cases and approving rates and tariffs for the companies Reviewing, analyzing and hearing water utility applications to pass-on wholesale cost increases in the cost of water Granting certificates of public convenience and necessity for major facilities Establishing accounting and depreciation procedures for utilities Approving mergers, acquisitions and transactions between companies Approving the issuance of securities and creation of liens by the utility Mediating consumer complaints regarding water service issues
