PROJECT DESCRIPTION
The"Yelm Apartments"project is located in the NE1/4 of the SE1/4 of Section 24,
Township 17 North, Range 1 East of the Willamette Meridian in the City of Yelm in
Thurston County, Washington. The proposal consists of construction of(2) 8 unit
apartment buildings for a total of 16 proposed units and associated parking/access and
open space areas onsite. The property is approximately 1.14 acres in size located at the
site address of 304 Longmire St. on parcel #21724410200. Surrounding properties
consist of a golf course to the south and existing Multi-Family complexes. This site will
be served by the City of Yelm for water and sanitary sewer. Additional utilities include
Puget Sound Energy for power and Qwest Communications for telephone.
EXISTING SOIL CONDITIONS
Per the S.C.S. soils map, on-site soils consist of Spanaway gravelly sandy loam which
will very conducive to infiltration of stormwater for proposed improvements onsite.
Pacific Geo Engineering, LLC performed an onsite soil investigation on August 6, 2013
at(9)test pit locations onsite to approximate depth of 11 feet and performed field
percolation testing at(3) of these(9) total test pit locations. It was determined from there
testing that an"in field"infiltration rate of 12 in/hr exists onsite within the native soils.
We have taken this information and applied a factor of safety of(2) for a design
infiltration rate for onsite infiltration trench facilities of 6 in/hr which we utilized for our
Final Stormwater Quantity Control design.
SANITARY SEWER SYSTEMS
The(2)proposed aparhnent buildings will each discharge via 6"building sewer lines @
2.0%(min.) to a respective 3,000 gal. concrete STEP tank and then continued conveyance
via 6"building sewer line @ 2.0%(min.) to a"joint" 3,000 gal. concrete STEP tank
containing(1) duplex Orenco pump package or approved equal. The duplex pump will
be controlled with panel located on 4"x4"wooden post fitted with a transfer switch
model DT 323 URK as mfg. by Culter Hammer and a male plug, mode170530 MBWP as
mfg. by Bryant. Pumped discharge will leave the "joint" STEP tank via a 2"discharge
STEP pressure line routing flows out to the existing 2" STEP stub located in the
northwestern corner of the site extending from Longmire St. Flows will then enter the
existing 4" STEP main in Longmire St. for continued conveyance. See STEP Tank
Sizing and pump/tank specifications attached to this report for additional information.

B. Detention Volume STEP/SDG
The detention volume or liquid volume of a STEP or SDG tank that serves
a single-family home or small business must equal at least 950 gallons.
Detention volume is defined as the volume of liquid below the"OFF"
switch(STEP)or the outlet pipe(SDG). Size tanks that serve structures
with higher wastewater discharge volumes in accordance with the
following equation:
r�V= 1.SQ(residential strength waste)
V=2.OQ(nonresidential strength waste)
Where:
V=Liquid volume
Q=Peak day flow for the structure being served
The equation provides the minimum liquid volume within the STEP/SDG
tank.The tank must also contain sufficient working volume and storage
volume. Liquid volume must not exceed approximately 65 to 75 percent of
the total tank volume.
C. Working Volume STEP/GP
� The working volume must exceed the difference between the peak influent
�,,n,r`�-- ' flow and the discharge of the STEP or grinder pump over a period of time
�� estimated to be the peak duration.Working volume is defined as the
volume between the"ON"and the"OFF"switch.
D. Storage Volume
STEP, SDG,and GP vessels (tanks)must have a minimum of 24 hours of
storage within the tank except as allowed(see C1-10.1.6E.2). Install tanks
without 24 hours of storage with a power transfer switch with an
emergency generator plug or other device to allow emergency power
connection.Alternatively,provide reserve volume with a separate vessel.
Storage volume is defined as the volume between the"OFF"switch and
the top of the tank. Tank designs must ensure that most of the storage
volume exists between the"ON"and"OFF"switches and limit storage
volume below the"OFF"switch. Allowing large volume of storage below
the"OFF"switch can promote septic conditions within the tank,which can
cause corrosion and odor problems for the entire system.
E. Power Outages
1. Applicability
STEP, SDG,and GP systems installed in areas with a history of
prolonged power outages may require additional storage volumes.The
designer must review historical records of the local power purveyor to
determine the advisability of adding more storage.
2. Power Transfer Switch/EG Plug
For vessels without 24 hours of storage,provide a power transfer
switch with an emergency generator plug. Limit the number of tanks
installed with power transfer switches to the number of tanks or

2.5.1.1 Residential Flows
In order to estimate the amount of residential flow treated at the WRF, average winter water use records
for the last 3 years were analyzed. Residential use accounted for approximately 75 percent of water
demand for the last three winters; residential flows at the WRF were therefore estimated to be 75
percent of the average influent flow.This equates to an average flow of 0.27 mgd and approximately 43
gallons per day(gpd) per person.
An ERU is defined as the flow produced by one avera c ' s' I il ' u it. B e on
U.S. Census data for 2010,there were approximatel 2.98 people�er eac�h r�eJ dentia� ousing unit �
within city limits. Compared to the sewered population o 6,�$;fhis equates to 2, 3 c ed
and 127.41 gpd/ERU.
2.5.1.2 Non-Residential Flows
Based on winter water use records, commercial wastewater flows were determined to comprise 22
percent of the average influent flow at the WRF, or 0.07 mgd. When compared to commercial
development analysis,this flow rate is equivalent to approximately 0.13 gallons per day per square foot
(gpd/ft2)of commercial development(5,660 gpd/acre).
Wastewater flows from schools were determined to comprise 3 percent of the average influent flow at
the WRF,or 0.01 mgd.The 2010 WSP estimates a student population of 3,889 within city limits.This
equates to approximately 2.6 gpd per student.
2.5.1.3 Infi(tration and Inflow
Infiltration and inflow(I/I) is defined as flow entering a system through groundwater(infiltration)and
precipitation (infiow).The total flow through a system is therefore the sum of the base wastewater flow,
plus the I/i. Infiltration and inflow in the Northwest typically follows a seasonal pattern,with high levels of
I/I during the wet winter season and low levels of i/I during the summer.
Yelm's collection system consists entirely of STEP tanks,which pump flow from individual connections to
the WRF. Because the entire system is pressurized, it is resistant to I/I.The City's 2011 Inflow and
Infiltration Report, prepared in January 2012, does not report any significant I/I in the system.The 2011
I/I Report is included in Appendix 2B.
In 2011,the difference between the maximum month influent flow and minimum month flow was only
0.031 mgd, indicating that wet weather does not have a strong impact on flows at the WRF. Figure 2-5
provides an example of a typical wet weather month's comparison of daily influent flow to rainfall.As
shown in the figure,there is no correlation between daily rainfall and influent flow. For this reason,
additional flow due to I/I is not included in the flow characterization or flow projections.
