INTRODUCTION

The Country Inn & Suites is planning to develop a new 4 story hotel near the intersection

of the NEC of Thomas Road and 73rd Street in the City of Scottsdale. The hotel will have

44 rooms and 2 condo suites in total. The proposed project is approximately 0.84 acres of

undeveloped land. A new 2” domestic water service and 8” fire service are proposed

to serve this project. Enclosed in this report are a fire flow test of the existing 8” water line

at the connection point, current and future demand calculations, and final calculations

in future conditions.

EXISTING CONDITIONS

There is an existing 8” water line proposed for connection in Thomas Rd. that has a static

pressure of 90 psi and a residual pressure of 80 psi. The available flowing gpm at this

location is 1973.3 gpm.

PROPOSED CONDITIONS

44 Guest Rooms and 2 Residential Condos

Total Floor Area is approximately 35,000 SF.

DESIGN CRITERIA

Average Day Water Demands - 0.56 gpm (inside use), 0.07 gpm (outside use), 0.63 gpm

(Total Use), per DS&PM figure 6-1.2

Max Day Peak Factor = 2.0

Peak Hour Factor = 3.5

Building Type VB, includes concession on square footage and reduction of fire flow to

1500 gpm by City of Scottsdale Fire Department. Typical fire flow for this coverage

area, would be minimum of 2000 gpm using Type IA and IB construction. See hydraulic

analysis for further detail.

Minimum Fire Flow = Max Day + 1,500 gpm

PROPOSED DESIGN FLOW

Average Day Demand = 0.63 gpm * 46 = 28.98 gpm

Maximum Day Demand = 28.98 x 2 = 57.96 gpm

Peak Hour Demand = 28.98 x 3.5 = 101.43 gpm

DOMESTIC METER SIZING

The proposed service line and meter size for the Country Inn & Suites is 2”. The following

design process is used to determine the meter size per Figure 6-1.4 of Scottsdale DS&PM.

As required, the Initial Service Line Design Flow is calculated from 2015 IPC Appendix E.

The number of fixtures units per room is calculated based on a lavatory, water closet,

and shower. The number of water supply fixture units per room is 4.3. Since there are 46

rooms, the total number of fixture units is 197.8. Using table E103.3(3), the total demand

SCOTTSDALE COUNTRY INN & SUITES

9-DR-2019, REV 1

3

is 65 gpm. Based on the criteria in the DS&PM, add 10 gpm and multiply by 1.5 safety

factor. The final initial service line design flow is 112.5 gpm < 160 gpm as required.

HYDRAULIC ANALYSIS

The fire line calculations begin from the point where the static pressure was measured

and extend to the entrance of the building, then up to the farthest point of the sprinkler

system. The initial energy grade line at the starting point is de-rated to 72 psi (166.32 ft).

Friction, velocity, and elevation line losses are generated based on the sum of

maximum day plus fire flow demands for the building and height of the facility. Upon

entry into the building, a network of sprinklers are carried to the most distant point of the

building. Each sprinkler shall provide a minimum coverage of 200 SF. Estimating 15 gpm

per head, the total number of sprinklers is 175, with a demand of 2625gpm. To

calculate the head loss due to elevation difference, the height of the highest sprinkler

shall be 40 feet above finished floor. Refer to calculations in figure 3 for additional

calculations. The resultant pressure in the line calculated during operation is 36.78 psi.

CONCLUSIONS

The proposed project will provide for a new 2” water meter and domestic service and a

separate 8” fire line which will tie into the existing 8” water line in East Thomas Road. The

water lines in the Country Inn & Suites project will conform to the City of Scottsdale DS&PM

and 2015 IPC. Proposed water construction, materials, and appurtenances shall be per

DSPM, Chapters 6 & 7 and the City of Scottsdale Standard Detail Series 2300 and 2400.

This flow test data is taken with pressure gauges which are calibrated for accuracy annually. We warrant that the results given are accurate for the time and date noted. We do not guarantee the results beyond this time due to daily or seasonal use, or water system changes. Careful consideration should be given to these issues when utilizing this information.
