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.

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 104 is a full size 4° (100mm) check valve for normal water service. 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. ProximitV Switch Option Neer a Signals That the Check Valve is en? An inductive type Proximity Switch can be furnished mounted on the valve body with its target mounted internally on the flapper.

' Vann is a €eglstered name of DuPont. 3 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.
