1.0 Introduction
This study herein provides analyses of the flows anticipated to each of the buildings for
proper sizing of the master meter for each building. Additionally, since there are two
pressure zones adjacent to the project, alternatives for water system supply to the project
are analyzed including meter sizing based on the different pressure zone service
opportunities.
2.0 Alternative 1 -375 Zone Water System
2.1 Alternative 1 Meter Sizing for 375 Zone
In accordance with A WW A standards for meter sizing, the method utilized to establish
the flow requirements to size the master meters to the buildings is the total fixture value
method. Pursuant to the A WW A M22 manual for sizing service lines and meters, it is
stated that fixture values are applied to demand curves and that the demand curves are not
linear as fixture counts increase. (See the figure below as copied from the A WW A
Manual.) Therefore, it is appropriate to size the master meters for each building based on
the total fixture count for that building.

In accordance with A WW A specifications as shown in Table 2 below from the A WW A
C700 standard, the recommended design criteria for sizing meters is that the peak design
flow should not exceed 80% of the meter maximum capacity. Based on meter capacity,
the flow of about 80 gpm as shown in Table 1 is about 80% of the capacity of a 1 ¥2-inch
meter. (A 1 Y2-inch meter has a maximum capacity range of up to 100 gpm.)

2-inch meters have a capacity of 160 gpm. A design flow of 80% of maximum capacity
would be 128 gpm, which would be about 60% larger than what is needed and could be
less efficient. Therefore, a 1 ¥2-inch master meter is recommended for all buildings. Table
3 below provides the recommended meter size and design flow for each building.

2.2 Alternative 1-375 Zone Water System Hydraulic Analysis
To serve the project from the existing 375 Pressure Zone would require a new connection
to the 12-inch pipeline in Poinsettia Lane. In order to provide a secondary supply, a
connection would need to be made to the existing 30-inch 550 Zone pipeline in Cassia
Drive with a new pressure reducing station at Cassia Drive and Drive "C". For the system
to operate properly without the new PRV filling the 375 Zone tank, the PRV is assumed
to have a setting no higher than the 387-ft HGL, which is the low water level in the tank
serving the 375 Zone.
A hydraulic analysis was perlormed using computer modeling software for peak hour and
maximum day plus fire flow demands. The analysis assumed the HGL of the tank to be
half full at 400·ft. The peak hour demands were conservatively assumed to be the total
fixture value for the entire project with a resulting peak demand of 128 gpm. The
resulting pressure, or HGL, at the water main in the street was then used to size the
service laterals and meters to each building based on the peak design flows shown in
Table 3.
The fire flow analysis was perlormed based on a fire flow of 2,750 gpm. The results
show that the minimum residual pressure is 35 psi at the hydrant near buildings 2 and 3.
Modeling results are provided in the Appendix.
The hydraulic analysis for the laterals and meters to each building included the peak
design flows and pressure losses through the lateral, master meter, and the sub-meter
pressure loss. The sub-meter was assumed to be a 5/8" meter. Table 4 provides a
summary of the resulting pressures to the front of each building first and top floors.

Pressures mclude pressure loss through 1 W' lateral, 1 W' master meter and 5/8" sub-meter.
As shown in Table 4, the resulting pressures for buildings 4 through 9 do not meet the 40
psi criteria.
3.0 Alternative 2 • 550 Zone Water System
Since there is a 30~inch 550 Zone pipeline along Cassia Drive, an alternative system that
would meet the minimum pressure criteria would be to serve the project entirely from the
550 Zone. Connections for a looped pipeline would be made to the existing pipeline at
Cassia Drive and Drive "C", and with a pipeline connection from the intersection of
Cassia Drive and Poinsettia Lane. The hydrant along Drive "B" would be served directly
from the existing 30~inch pipeline in Cassia Drive .
3.1 Alternative 2-550 Zone Flows and Meter Sizing
The same fixture value method is used for determining the flows and sizing of the meters
for the 550 Zone. However, since the pressures from the 550 Zone are higher, the
pressure factor applied to the fixture value flow is greater. This yields a higher peak
design flow to each building. Table 5 provides a summary of the 550 Zone peak design
flows and meter sizes. Additional detail is provided in the Appendix.

3.2 Alternative 2 -550 Zone Hydraulic Analysis
1 -----1

1
A hydraulic analysis was performed using a computer modeling software for peak hour
and maximum day plus fire flow demands. The analysis assumed the HGL to be a farily
constant 550 -ft. The peak hour demands were conservatively assumed to be the total
fixture value for the entire project with a resulting peak demand of 165 gpm. The
resulting pressure, or HGL, at the water main in the street was then used to size the
service laterals and meters to each building based on the peak design flows shown in
Table 4.
The pressures at the buildings range from 121 psi to 131 psi. The system pipelines,
valves, and fittings should be designed for a higher pressure class rating to accommodate
these pressures. Additionally, individual pressure regulators should be installed at each
master meter with a second or backup pressure regulator installed at each sub-meter to
each unit.
The fire flow analysis was performed based on a fire flow of 2,750 gpm. The results
show that there is more than adequate pressure with a minimum residual pressure is 113
psi.
The hydraulic analysis for the laterals and meters to each building included the peak
design flows and pressure losses through the lateral, master meter, pressure regulators,
and the sub-meter. The sub-meter was assumed to be a 5/8" meter. Table 6 provides a
summary of the resulting pressures to the front of each building first and top floors.

Pressures include pressure loss through 2" lateral, 2" master meter, 2 pressure regulators and 5/8" sub-meter.
4.0 Alternative 3 • Split Zone 375/550 Zone Water System
Analysis
As shown in Table 2 for Alternative 1 buildings 1, 2, and 3 meet the minimum pressure
criteria, but yield pressures exceeding 130 psi for the 550 Zone. Therefore, as a third
alternative these buildings are proposed to be served from the 375 Pressure Zone from the
12-inch pipeline in Poinsettia Lane. A single pipeline which would serve a total of 21
units (or three 1 W' meters) and one fire hydrant is proposed for this 375 Pressure Zone.
The remaining units, buildings 4 through 9, would be served directly from the 550
Pressure Zone. Two connections would be made to the existing 30-inch pipeline in Cassia
Drive, one at Drive "B" and at Drive "C". A single line serving one fire hydrant and 20
units would supply buildings 4 and 5. Static pressures range from 121 psi to 128 psi. The
maximum static pressure will be at building 4, with a maximum static pressure of 128
psi. Pipelines, valves, and fittings would need to be designed for the higher pressure class
ratings accordingly.
4.1 Alternative 3 -Split 375/550 Zone Flows and Meter Sizing
Flow and meter sizing to each building varies for this water system depending on the
pressure zone, the 550 Zone meters are slightly different due to the higher pressures in
the 550 Zone that result in a higher adjusted design flow for sizing meters per the
A WW A criteria. Table 7 provides the revised flow conditions for this system layout.

Adjusted Peak Design Flow for buildings 4-9 are based on pressures from the 550 Pressure Zone.
As shown in Table 8, the meter size for the meters within the 550 2'.one reflect a higher
flow rate due to the higher pressure adjustment factor, and will need to be 2-inch meters
since they exceed the 80% capacity design flow criteria for a 1 ~-inch meter.

4.2 Alternative 3 -Split 375/550 Hydraulic Analysis
The hydraulic analysis was performed for the 375/550 Split Pressure Z.one system with a
summary provided in Table 9. The meters within the 550 Zone are assumed to be
equipped with 2-inch pressure reducing valves to reduce pressure to a maximum of 80 psi
per the plumbing code.
Additionally, for added reliability a second pressure reducing valve would be added at the
sub-meter to each unit.

Pressures for the 550 Zone include pressure loss through the lateral, master meter, pressure regulators, and
5/8" sub-meter. Pressures in the 375 Zone do not include a pressure regulator since maximum pressures are
less than 80 psi. The 550 Zone includes PRY at the master meter set to 80 psi.
The fire flow analysis for the 375 Zone was performed based on a fire flow of 2,750 gpm.
The results show that the minimum residual pressure is 51 psi at the hydrant near
buildings 2 and 3.
The fire flow analysis was performed based on a fire flow of 2,750 gpm. The results
show that there is more than adequate pressure with a minimum residual pressure of 115
psi.
