Due to the expiration of Reclamation's contract with PG&E on April 

1, 2016, PUE costs are projected to increase. In fiscal year 2016, 

the increase is expected to be $4 million and in 2017, the increase 

is projected to be approximately $6.9 million. These increases are 

included in the water rates.

The meter used to estimate Bella Vista WD cost for 2016 was not 

correct, resulting in a low estimate. Contractor was notified and 

2016 rate increased to cover expected cost.
