United Water proposes sale of Nampa area water systems


The Idaho Public Utilities Commission will take comments through Aug. 8 on a proposal by United Water Idaho Inc. to sell water systems serving some Nampa subdivisions to the City of Nampa’s municipal water system.


The affected subdivisions are Coventry Place, M&M Mountain View Acres and Belmont Heights. Also included in the proposed sale are the Lexington Meadows and Brittania Heights subdivisions, which are part of the Belmont system.


The proposed purchase price for the water systems is $245,000. All customers other than those in the M&M Mountain View subdivision would experience an increase in rates for water service of about 12 percent if this application is approved. The subdivisions fall outside Nampa city limits and those customers pay a higher rate than those inside the city. Customers at M&M Mountain View are unmetered and billed at a flat rate by United Water. They would continue to be billed by the city at the same United Water flat rate, according to the proposal.


United Water proposes a sharing of the sale proceeds between the company’s shareholders and ratepayers. The portion going to United Water ratepayers would be reduced from the company’s rate base when it files its next general rate case.


United Water maintains the sale of the water systems is in the public interest because the growth of Nampa subdivisions is resulting in the city being served by multiple water suppliers in close proximity. Further, United Water states, the City of Nampa is a dependable municipal supplier and interconnection of the Belmont system with the city will solve an existing water quality issue involving elevated levels of uranium in Belmont Heights.


The commission intends to proceed under a modified procedure that allows this case to be handled through written public comments rather than by public hearing. However, comments may request a public hearing.
