TTNTRODUC-TION
The Edmonds Park Apartments is an existing, residellti-,l WAY, 53 Unit /Bedroom and
Studio apartment building located- at 424 3rd Ave South in Edmonds, Washington. The
project is entirely multi-fan3ily residential, and there are no plans to expand the project
in terms of number of apartment units, size of existing apartments, or bathrooin size,
quantities, and configurations.
The sewage pump station will have duplex submersible style pumps with 10o%
redundancy, each pump sized for the peals building flow rate utilizing the following
Tables and Charts from. the 2-012 Uniform Plus- bing Code:
Appendix A, Chari A2.I
Appendix C, Table C4.1(1)
These Tables are incorporated into our spreadsheet titled "Total Nater & Sewer
Calculations, APPENDIX "A" in this report.
The existing pump station structure will remain in place, and be reconditioned. The top
section of the existing pump station structure will be replaced with a new straight
section(in lieu of cone shaped) to permit adding pump rails to the structure for easy
access and: servicing of the pumps.
The pump station predicted average flow conditions is 3.0 gallons per hour per
apartment (Based on APPENDIX "C" ASI-IRAE- 2011 Applications Handbook for
Apartments). For this application, the predicted average hourly flow of sewage into the
existing lift station is:
Average Hourly Flow = 53 Apt Units x 3.0 gal/apt = 159 gallons per hour
The existing capacity of the existing pump station (including the 8FT x S IT x 6o" high
(inside) upstream manhole) is:
Pump Station Capacity = 176.7 FT3
Upstream Manhole = .2� o FT3
496.7 FT3 x 7.45 Gal = 3,715 gallons
FT3
Number of hours of 1,715 gallons
reserve capacity in = 159 gallons/hr 23.4 hours
available tanks on site
I P- -r -N E ngim-,��riacj, fiic
The actual field tinned measurements indicated the pumps (one pump) was cycling on
average once per hour at a volume estimated to be 150 to 200 gallons.
The existing wet well is being reused for this project so the buoyancy calculations are not
required.
Pump Cycle Times: Please see the attached Pump Cycle Time Calculation (APPENDIX
"F„
In summary, the pump will average about 5 starts per hour, with a peak of 8.2 starts per
hour.
Wet Well Capacity:
Total Volume: 6o" dia x 9 feet deep = 176.7 FT3 or about 1,322 gallons
The new pumps are replacing existing pumps of similar capacity so no surge analysis
should be required. The new (non -slam) check valves will minimize any hydraulic
conditions like water hammer.

SwingAPCO Rubber Flapper
Description er opt_ is backflow procedure. This Backflow Device is positive
APCG rubber flapper swing check valves are uniquely and will not slip during full backflow.
simple in design but durable for use on a variety
of applications.
With only three major parts, Body, Flapper & Cover,
there is relatively no maintenance. However, should
maintenance be required, the flapper can be replaced
in a matter of minutes. The valve body seat is on an
angle of 45° to the centerline of the pipe, permitting
horizontal or vertical flow up installation. With the
flapper ful( open, there is a straight unobstructed flow
passage, so all foreign matter is flushed away by the
flowing medium. This eliminates clogging, Due to
this unobstructed flow passage the pressure drop is
considerably lower through the APC4 Rubber Flapper
Check than through conventional swing check valves.
Normally made of Cast or Ductile Iron, but readily
supplied in Stainless Steel or Bronze, the valve can
be lined or coated with various materials.
The flapper is normally Buna-N but can be
compression molded from various synthetic rubbers.
A steel disc for strength and a steel bar are molded
inside the flapper. A hi -strength fabric is integrally
molded over the disc and bar to form a flexible
joint permitting millions of flexes without failure_
For operation with aggressive media, Buna-N has
excellent abrasion resistant qualities. When the valve
is assembled the flapper is firmly clamped between
body and cover. This feature eliminates problems
of moving parts, shafts, pins, bearings, bushings,
packings (as required in conventional check valves).
Further, this flapper design eliminates jamming or
sticking in the open position and the O-ring seal
molded into the disc face assures positive sealing,
even at lower pressures_ Recommended for buried
service with stainless steel cover bolts. Rated
125#/150# Class for 175 psi differential pressure_
Nigher. pressure class available.
2. Q 2011 D) ,ZHR€R, Inc
The Backflow Device can be removed for service
without removing the check valve or taking the
pump out of service. Size 3" and 4' (80 and 100mrn)
Backflow Devices are constructed of Bronze ASTM
B-584 as approved by U.S. Navy for fleet service.
Should your next pump station design require a
by-pass or backfiow through the check valve for any .
reason.-, do it safely!

Model 1041=3, designed specifically for raw sewage
with a flow area thru the seat almost twice (23.75",
604mm) that of standard pipe (12.73", 323mm),
permitting the 104P3 to pass a 3" (76mm) diameter
solid as required by many states and municipalities for
4" (100mm) check valves used on sewage.
This feature is of special interest to sewage lift station
designers_
ow Control Option
Need to Throtdo or Sheet- ow?
The f=low Control device is used to restrict the position
of the flapper far -the purpose of regulating flow into
the system or to create a false head on the pump.
The device is mounted on the cover of the valve and
when manually operated will prevent the flapper from
fully opening. With this device, the Rubber Flapper
Check Valve can be used as a stop check.

APCO has manufactured Rubber
Flapper Swing Check Valves (RFSCV)
since 1955. We have many thousands
of units in the field that have been
operating successfully for decades.
From time to time, engineers or
end users have a difficult high head
application where rapid flow reversal
causes standard style Swing Check
Valves to slam. The APCO 100SR
was developed in 1978 to eliminate
or minimize slam in these types of
installations. The APCO 100SR has
successfully managed surges (due
to rapid flow reversal) even in tough
vertical 'flow up' installations. See
comparison graph on page 5_ !
The Standard Series -100 RFSCV has a
35° Disc Stroke and will close relatively
quickly. This Stroke is very short
compared to conventional Style Swing
Check Valves which typically have 80°
to 90° disc travel_ When you add the
spring return to the RFSCV it causes
the disc to speed up or accelerate to
valve closure. Having the Valve closed
beforereverse flow takes place can in
many instances, drastically reduce or
even eliminate valve slam. .
Simplified Spring design also -available. I00SA
Position Disc Indicator also available on all
