HYDRAULIC ANALYSIS CERTIFICATION

I hereby certify that the hydraulic modeling analysis for:

Valley Meadows
(Project Name or Description)

Uintah City Water System
(Water System Name)

#29020
(Water System Number)

#16246
(DDW File Number, If Available)

Meets all requirements as set forth in R309-511 (Hydraulic Modeling Rule) and complies with
the provisions thereof, as well as the sizing requirements of R309-510, and the minimum
water pressures of R309-105-9. Where applicable the proposed additions to the distribution
system will not cause the pressures at any new or existing connections to be less than those
specified in R309-105-9. The model is sufficiently calibrated and accurate to represent the
conditions within this water system. The velocities in the model are not excessive and are
within industry standards. The hydraulic modeling method was completed using computer
software, and the computer software used was EPANet 2.0. (Note: This certification does
not imply that all existing parts of the City’s water system comply with the current Rules. Certain
parts of the system may have been constructed prior to the adoption of some Rules.)
