Technical data, performance curves, and cut sheets are provided in Appendix A for an
EFI package pump station. This is a sample of what is required of the proposed pump
station and is provided for informational purposes only.

The pumps will be run off a pressure sensor located within the distribution system to
ensure that adequate pressure remains in the system at all times. The CDPHE states that
the normal working pressure in the distribution system should be approximately 60 psi
and not less than 35 psi.

5. Distribution Layout
The general locations of the new water lines are shown in Exhibit 1. Key information
such as length and size are included in the figure. The new four-inch (4") lines will be of
C-900 PVC or ductile iron pipe (DIP). The alignments generally follow the County
Roads except for a few sections that cross through private property to avoid cultural
resources. These sections are highlighted in the Cultural Resource Inventory of
Goodman Point Water Association's Domestic Water Delivery Project. There will be a
total of approximately 9.6 miles of new 4" water main installed.

Water distribution system pipe diameters are designed to provide the peak hour demand
while maintaining a minimum working pressure. The CDPHE recommends a normal
working pressure of 60 psi with a minimum working pressure of 35 psi. The planned
distribution system will meet these recommendations.

Hydrants will be located throughout the distribution system to provide water access to the
local fire protection district. These hydrants are not provided for fire protection, but to
enable fire tanker trucks to fill up their tanks for fire fighting purposes. Specifically,
hydrants will be located at road intersections and will be required to meet MWC
specifications as shown in Appendix B.

B. Cost Estimate
An opinion of cost for all required work is presented in Table VII-3 below.
