The system has
been calculated to provide
an
average
imbalance at
each node of 0.001 gpm
and a maximum
imbalance at
any node of 0.009 gpm.

Total pressure
at each node is used
in balancing
the system.
Maximum water
velocity is 10.7 ft/sec
at pipe
8.

INFORMATION PROVIDED BY WATER AGENCY
1. N a. Water will be provided by service connection only to an existing iz-inch (size) water
main that is adjacent to the site.
OR
❑ b. Water service will require an improvement to the water system of:
❑ (i). feet of water main to reach the site; and/or
❑ (z). The construction of a distribution system on the site; and/or
❑ W. Other (describe):
z. N a. The water system is in conformance with a City approved water comprehensive plan.
OR
❑ b. The water system improvement will require a water comprehensive plan amendment.
(This will cause a delay in permit issuance and approval.)
I N a. The proposed project is within the corporate limits of the City, or has been granted Boundary
Review board approval for extension of service outside the City, or is within the City approved
service area of a private water purveyor.
OR
❑ b. Annexation or Boundary Review Board approval will be necessary to provide service.
q. N a. Water is/or will be available at the rate of flow and duration indicated below at no less than zo psi
Measured at the nearest fire hydrant ioo feet from the building/property (or as marked on attached map)
Rate of Flow Duration
❑ Lessthan 500 gpm. (approximately gpm) ❑ Less than one (i) hour
