Gallatin County Courts
Water Distribution Design Report
1 EXECUTIVE SUMMARY
This report provides a design basis for additions and modifications to the Gallatin County Law
& Justice Center’s existing water distribution system. The changes are needed to
accommodate demolition and replacement of miscellaneous site improvements and two existing
buildings on the site (Law & Justice building and Courts Annex) with a new County Courts
building and associated new site improvements. The water distribution system modifications
and additions will be designed and installed in accordance with the Montana Department of
Environmental Quality (MDEQ) Circular No. 1; Montana Public Works Standard Specifications
(MPWSS); The City of Bozeman Modifications to MPWSS; City of Bozeman Water Facility Plan;
and the City of Bozeman Fire Service Line Standards.
This design report demonstrates that there will be adequate volume and pressure to supply
domestic and fire service for the entire Law & Justice Center for all of the existing buildings to
remain plus the currently proposed replacement building.
The water model also incorporates additional, estimated water demands to accommodate future
buildings that may be added to currently undeveloped or underdeveloped portions of the site.
The future buildings are included to demonstrate that some level of additional development on
the site is feasible without the need for additional water mains. Once the domestic and fire
water demands are determined for future buildings, the model can be updated to confirm
adequate flow capacity.
This design report follows the section numbering of Circular DEQ-1-Standards for Water Works,
2022 Edition, Section 1.1, Engineer’s Report.
2 GENERAL INFORMATION (DEQ 1.1.1)
a. The Law and Justice campus is a roughly square parcel of about 19 acres. There are
five buildings on the site: Detention Center, Law & Justice Building, Document Storage
Building, Pre Release Building and Courts Annex Building. Existing site access is from
Dickerson Street to the west and South 16th Avenue to the south, both of which end at
the site boundary and are connected through the site as a parking access drive. There
is also an undeveloped access point at the site’s northeast corner, for a connection to
South 15th Avenue that will be developed with this project.
The following is the legal description for the property:
Tracts A and B, Certificate of Survey 691 and a parcel as described in document
Film 5 page 146, less dedicated right-of-way per Certificate Of Survey 429, located in
the SW1/4 of Section 12, Township 2 South, Range 5 East, Principal Meridian,
Gallatin County, Montana.
b. The proposed water main infrastructure will be operated and maintained as part of the
City of Bozeman’s water distribution system. Sanitary sewer service to the new County
Courts building will be through a new 6-inch sanitary sewer service discharging to an
existing City of Bozeman sanitary sewer main located just west of the site’s west
property line.

c. Project Developer: Gallatin County
311 West Main St., Room 311
Bozeman, MT 59715
System Owner: City of Bozeman
PO Box 1230
Bozeman, MT
3 EXTENT OF WATER WORKS SYSTEM (DEQ 1.1.2):
The proposed water mains are extensions of the City of Bozeman water infrastructure. The new
internal 8-inch lines will tie into three existing water mains. The project will occur in two phases,
to allow continued service during Phase 1 to the two buildings that will be demolished in
Phase 2, followed by completion of the new looped connection between the existing 6-inch
water mains.
Phase 1:
- At the north site boundary, a proposed 8-inch main will connect to an existing 8-inch
main and extend south approximately 167 feet south and will terminate at a proposed
4-inch domestic service line. In addition, a 6-inch fire hydrant lead will be installed and
will terminate at a new fire hydrant.
- At the west site boundary, a proposed 8-inch main will connect to an existing 6-inch tee
and run west into the site. The east-west leg of the water main will be capped in
Phase 1 about 275 feet east of the site’s west property line, just west of a new fire
hydrant. In addition, two 6-inch fire hydrant leads will be installed and will terminate at
two new fire hydrants.
Phase 2:
- From the above-described new fire hydrant and temporary end cap, the 8-inch water
main will be extended east and south to its connection to an existing 6-inch water main
that currently dead-ends at a fire hydrant; this will complete the new water line loop. In
addition, a 6-inch fire hydrant lead will be installed and will terminate at a new fire
hydrant.
The existing and proposed water mains will serve the entire Law & Justice Center property, and
will provide additional looping for redundancy and improved reliability to several adjacent
properties. The proposed water main loop through the site was located to allow for future
connections to undeveloped or underdeveloped areas on the site.
4 ALTERNATE PLANS (1.1.3)
No alternate plans were considered.
5 SITE CONDITIONS (1.1.4)
The proposed Gallatin County Courts site is an existing development and determined by USDA
Natural Resources Conservation, Web Soil Survey as urban land, thus the geotechnical report
was used for determining the characteristics of soils through which the water mains are to be
laid. The Law and Justice Center geotechnical report dated February 2016, prepared by Allied
4
Engineering, states soils near 6.5’ depth are mostly native sandy gravels and, in some areas,
native silt/clay soils appear. Seasonal high ground water ranges from seven feet to thirteen feet
below existing grade and generally flows to the north/northwest.
6 WATER USE DATA (1.1.5):
The water distribution system serving the proposed project will be designed and installed in
accordance with the Montana Department of Environmental Quality (MDEQ) Circular No. 1;
Montana Public Works Standard Specifications (MPWSS); the City of Bozeman Modifications to
MPWSS; City of Bozeman Water Facility Plan; and the City of Bozeman Design Standards and
Specifications Policy. The following section addresses the design capacity and flow
requirements discussed in Section 8 of DEQ-1.
The water demand for the proposed Gallatin County Courts building can be determined from the
current usage of the Law and Justice Center and DEQ Circular 4. Currently, the water usage or
Average Day Demand is 0.03 gpm for the existing Courts Annex Building, and 8.84 gpm
combined for the existing Jail (Detention Center) and Law & Justice Center buildings. The
currently proposed Courts Building will essentially take the place of the Courts Annex and the
Law & Justice building, both of which will be demolished as part of the project. It is assumed
the water demand for the new building will be equal to that of the two buildings being
demolished, although it will be somewhat less due to a reduced maximum employee count.
In anticipation of future development in the southern part of the site, Two future buildings were
added to the site-wide water model. No plans have been developed for the future buildings;
they are merely place-holders for a future update to this report. The average daily demands for
the two proposed office buildings were estimated using DEQ Circular 4, Table 3.1-1 which
states an office is estimated to use 13 gpd per employee. Table 1 shows the total Average
Daily Demand of 11.13 gpm, Maximum Daily Demand with a peaking factor of 2.3, and the
Maximum Peak Hour Demand with a peaking factor of 3.0.
Proposed Office Building 1: 90 employees X 13 gpd/employee = 1,170 gpd or 0.81 gpm
Proposed Office Building 2: 161 employees X 13gpd/employee = 2,093 gpd or 1.45 gpm
Table 1 shows a total Average Daily Demand of 11.13 gpm. The Maximum Daily Demand was
found by multiplying the Average Daily Demand by a factor of 2.3, and the Maximum Peak Hour
Demand was calculated using a peaking factor of 3.0.

Fire Flow
The total water demand for the system includes the Maximum Daily Demand and the minimum
required fire flow of 1,500 gpm which, based on the predicted building of Type V-A Construction
per Table B105.1(2) of Appendix B of the International Fire Code, requires 5,500 gpm fire flow
for a building without sprinklers and allows a reduction for buildings with fire sprinklers. The
reduced flow is 25% of the listed flow which is 1,375 gpm. The minimum flow is 1,000 gpm or
1,500 gpm depending on if the fire sprinkler system is designed to meet NFPA 13 or NFPA 13R
requirements. For this report, it is conservatively assumed that 1,500 gpm will be required. The
Maximum Daily Demand is calculated by multiplying the Average Daily Demand by a peaking
factor of 2.3.
Total Fire Flow = 25.60 gpm + 1,500 gpm = 1,525.60 gpm.
7 FLOW REQUIREMENTS (1.1.6)
Modeling Procedure
Water modeling using the proposed water main locations has been input into WaterCAD V8i
software to assess expected performance of the new distribution network. Water supply from
the existing City water system has been modeled by a reservoir and pump along West
Dickerson St and a second pump on South 15th Ave to mimic distribution system output. Use of
fire hydrant flow data and a reservoir/pump supply is a commonly used method to build a stand-
alone model without reproducing the complete distribution system. Pump curves were provided
by the City of Bozeman Water Department for fire hydrants at West Dickerson (West of the Site)
and at the intersection of West Story Street and South 15th Avenue.
The total water demand for the system includes the maximum daily demand and the required
fire flow of 1,500 gpm as determined by the Insurance Services Office (ISO) criteria. The
maximum daily demand is calculated by multiplying the average daily demand by a peaking
factor of 2.3. The minimum pressure used for pipe main sizing was 35 psi during normal uses
and no less than 20 psi residual pressure during fire hydrant full flow condition at any supply
node. A “C” of 130 is used for the Hazen Williams pipe roughness factor.
Modeling Results
The model’s results indicate that 8-inch distribution mains for the Gallatin County Courts
development will supply the needed maximum daily flow with fire flow while maintaining the
required 20-psi residual pressure at all points within the modeled area. Pressure during max
day ranges from 99 psi to 112 psi. The available fire flow is 3,500 gpm for the development.
Refer to Appendix A (WaterCAD Model) for additional information.

Dear Mr. Evans,
On January 18, four samples from the Law & Justice – Bozeman, MT project were delivered to our
AASHTO/ASTM accredited materials testing laboratory. The samples were given Lab Nos. 18352 through
18355. The testing was performed in general accordance with the following Standards:
• Measurement of Soil Resistivity (AASHTO T 288); • pH of Soils (MT 232); and, • Water-Soluble Sulfate in Soil (EPA 300.0).
The corrosivity testing results are presented in Table 1. Alpine Analytical of Helena performed the soluble sulfate
testing.
