09-0239 STEP Design _ Calcs 120909YELM, WASHINGTON Prepared For: Les Schwab Tire Centers 20900 Cooley Road Bend, OR 97701 Prepared By: Jeremy F. Haug, E.I.T., Project Engineer Approved By: Brett M. Allen, P.E., Principal Project # 09-024 I hereby state that this Storm Water Site Plan for Les Schwab Tire Center of 805 Yeim Avenue East has been prepared by me or under my supervision and meets the standard of care and expertise that is usual and customary in this community of professional engineers. I understand that City of Tacoma does not and will not assume liability for the sufficiency, suitability or performance of drainage facilities prepared by Contour Engineering PUC This analysis is based on data and records either supplied to, or obtained by, Contour Engineering, PLLC These documents are referenced within the text of the analysis. The analysis has been prepared utilizing procedures and practices within the standard accepted practices of the industry. PAGE 1.0 PROJECT OVERVIEW.................................................................................................................................2 2.0 STEP SYSTEM DESIGN AND CALCULATIONS.................................................................................... 2 Appendix A' STEP System Design Exhibits Appendix '8' Calculations and Misc. Exhibits Appendix'C' Misc. System Specifications The proposed project is located at 805 Yelm Avenue East in Yelm, WA at parcel 22730121100. The proposed STEP system would provide sewer service for the existing facilities of Our Redeemer Lutheran Church which would replace the current septic system that is being utilized on-site. This STEP system and subsequent main extension application is in conjunction with the Short Plat application recently submitted for the division of the site into two lots and a tract. It is our understanding, that the Final Short Plat approval can not be given until the current Church facilities are connected to the City's sewer system. A proposed 4" STEP force main will be extended onto the project site along the access drive from the existing 8" STEP force main located in Yelm Avenue. The 4" main will be reduced to a 2" main at a 450 bend outside of the future access paving limits. The 2" main will be extended to where it is connected to the proposed Churches 1" service line. The existing STEP main runs along the south side of Yelm Avenue. (See Appendix 'A' for the STEP System Design Exhibits) This STEP sewer system was designed following the City of Yelm Development Guidelines. 2.0 STEP SYSTEM DESIGN AND CALCULATIONS Projected Flow Rate Assume a peak of 100 persons using the church facilities and campus at any single event per representatives of the church. Neither the City of Yelm Development Guidelines (Table 2 in Section 7C.020) nor the Department of Ecology Criteria for Sewage Works Design (Table G2-2) has a discharge category for a'Church' or anything similar. A design rate of 10 gpd per person is estimated for the facilities. See tables in Appendix'B'. Total Design Influent = QIN = 10 gpd/person x 100 persons; QIN = 11000 gpd Since, the peak number of persons is used in the calculations, the Total Design Influent, QIN, is the Peak Flow from the Church facilities. Tank Sizing Detention Volume, VD, (or Liquid Volume) is the volume of liquid below the "Lead On/Off' float as shown on City of Yelm Standard Drawing No. 7-14. (See Appendix 'B'). Per Section C1-10.1.6.6 of the Department of Ecology Criteria for Sewage Works Design, the required Detention Volume for Non -Residential is: Detention Volume = VD = 2.0 QIN = 2.0 x 1,000 gpd; VD = 2,000 gal Based on the calculated required Detention Volume and using the table provided on the City of Yelm's Standard Drawing No. 7-11, the appropriate tank size is 3,000 gallons. That would provide a Detention Volume of 2,400 gallons instead of the required 2,000 gallons. The 3,000 gal tank shall be a Containment Solutions, Inc. fiberglass tank (or approved equivalent) and shall meet all manufacture specifications outlined in Appendix'C', or as per approved equivalent, and meet all requirements outlined in the City of Yelm Development Guidelines. The tank shall have a dividing buffer which divides the tank so 2/3 of the volume is in the first chamber and 1/3 in the second chamber. There shall also be a 4 -in diameter hole in the center of the dividing baffle, 26 -in above the tank floor. A 4 -in vent hole shall be constructed within 1 -in of the baffle crown. Effluent Pump Assemblies A duplex pump system will be utilized since the tank size is 3,000 gal. Per City of Yelm standards, all STEP pump systems are required to be Orenco, or City approved equivalent. Pumps shall be Orenco model P20 0511 with an Orenco Biotube Pump Vault model X40 12xx-18 19. See Appendix'C' and paragraph below. Pump floats shall be Orenco model MF-A2GTwith floats set to `High Level Alarm", "Lag On/Off", `Lead On/Off', and "Low Level Alarm/Redundant Off'. See Standard Drawing No. 7-14 in Appendix 'B' as well as specs in Appendix'C'. The pump system is required to deliver 20 gpm against 105 -ft of TDH with a shut- off head of not less than 160 -ft. The system TDH was calculated at 51.2 -ft. (See Appendix `B') Appendix'C' contains only some of the required system specifications. Refer to City of Yelm standards and requirements as well as those of the manufacturer. Discharge Pipe Sizing The discharge pipe shall be 2 -in diameter Schedule 40 PVC with bedding requirements, joints and fittings meeting the requirements of the City of Yelm Development Guidelines. The working velocity through the 2 -in discharge pipe is calculated below: QWorkin9 = 40 gpm (assuming two pumps at 20 gpm each) = 0.09 cfs A2.in = 7r (1 -in / 12 )2 = 0.022 sq. ft. VWorking = Qworking / A2 -in = 0.09 / 0.022 = 4.10 ft./sec. The working velocity through the 4 -in discharge pipe is calculated below: QWorking = 40 gpm (assuming two pumps at 20 gpm each) = 0.09 cfs A4 -in = rz (2 -In / 12)Z = 0.044 sq. ft. VWorking = QWorking / A4 -in = 0.09 / 0.044 = 2.055 ft./Sec.

The process design of treatment units should be based on either the average design flow or the peak design flow, whichever is controlling. The following items should be determined from the observed rate of flow during the significant period of discharge. Items to be considered in determining design flows are as follows: Peak flow rates continuing over a length of time sufficient to adversely affect the detention time of treatment units of the flow characteristics in conduits. • Applicable data from similar municipalities. Wet weather flows. Recirculation and inplant recycle flows. The design organic loading should be computed in the same manner used in determining design flow.

The assembly is detachable without removal of the screened pump vault or effluent screen. A typical float switch assembly is shown below. Step 1: Each float cable is provided with a color marker. This marker indicates the function of the float. Make sure that your float cable color markers corre- spond with the wiring diagram provided. If the wiring diagram does not match your float cable marker colors, contact Of enco Systems® Inc. or your local dealer for assistance. Step 2: To check for proper float switch operation, move each switch up and down and check for interference. Remove the assembly from its holding bracket by snapping it out of the holding bracket. Float function color marker _ Float stem T Adjustable float collar Stainless steel set screw r Float © 2003 0,,nco Systems' Inc. NIN-MF-MF-1 Rea. 2.0,©11/04 Page 1 of 4 Installation Instructions (continued) W NIN-MF-MF-1 Rev. 2.0. © 77/04 Page 2 of 4 Step 3: If any float interferes with another, the float maybe adjusted by loosening the stainless steel setscrew provided in the float collar. Using a Phillips screwdriver, slowly back the screw out of the collar to a point at which the collar may be adjusted. Be careful not to back the screw completely out of the collar. Carefully rotate the collar on the stem until the float switches can move freely past one another. Tighten the stainless steel set screw and recheck. Warning: Be careful not to alter the the tether lengths of any of the floats. Alteration of the tether length may affect proper operation of the float switch assembly. Step 4: Check the float settings with the project plans and specifications. If the set- tings need to be adjusted, loosen the set screw as described in step 3. Adjust the float switches to the desired level and tighten the set screw. Make sure float level settings do not violate any state or local regulations. Note: The float stern provided is the maximum length possible without interfering with the pmnp minimum liquid level or screened pump vault intake ports. Never lengthen the float stern without prior approval from Orenco. Lengthening of the float stem will void the warranty. Step 5: Replace the float switch assembly in the holding bracket. Make sue the assembly snaps fully into the bracket. Step G: To allow for easy removal of a float switch assembly, a t" diameter handle may be added to the top of the float switch assembly. Measure the distance from the top of the float switch assembly up to about one foot from grade level. Cut a f" diameter PVC pipe to the measured length and glue it into the handle. © 2003 Oreaco Systems°' [tic. Insta nation Instructions (continued) Step a: When used with an Mesa electrical splice box: Push the level control wires through the watertight cord grips into the electrical splice box. Leave an adequate length of electrical cable coiled inside the riser to allow for easy removal of the pump and float switch assembly. Do not remove the colored markers or the paper tags from the float cables, and do not try to thread the markers and tag through the cord grip. Tighten the cord grips by hand, not by tool, then test the tight- ness of the cord grips by tugging on each cable. A cable is secure when the cord grip is tight enough to prevent slippage. Adequate lengths of cable should be left within the splice box to allow easy removal for future disconnecting and resplicing. Note: See the splice box insouciions (F -IN -SB -SB -1) and corresponding splice box diagram foconnection instructions. OM © 2003 O,enca Systems' Me. NIN-MF-MF-1 Rev. 2.0,©11/09 Page 3 of 4 During the annual inspection, follow the testing procedures provided to ensure that the system is operating properly. If afloat is found to be faulty, either during the annual inspection or during troubleshooting after an alarm condition, see the section below titled Removing and Replacing Inoperative Floats. Removing and Replacing Inoperative Floats Important: Before doing any work either on the wiring to the level control floats and pump in the vault or in the pump control panel, switch the circuit breakers in the panel to their "OFF" positions, then switch off the power to the system at the service entrance panel. 1. Remove the float assembly from the vault. 2. Using a Phillips screwdriver, remove the stainless steel screws fi om the splice box lid, being careful not to drop the screws into the tank. If the splice box was submerged, or if there is a crack in the conduit, there may be water in the splice box. If this is the case, remove water from the splice box with a syringe, sponge, or other appropriate method. Loosen the cord grip at the splice box and verify the appropriate splice for the float. Unscrew the wire nuts and remove the float. 3. Remove the inoperative float and replace it with a new one. Push the float cable through the watertight cord grip into the electrical splice box. Leave an adequate length of electrical cord coiled inside the riser to allow for easy removal of the float assembly. Do not remove the colored markers or the paper tags from the float cords, and do not try to thread the markers and tag through the cord grip. Tighten the cord grip byband, not bytool, then test the tightness of the cord grip by tugging on the cord. A cord is secure when the cord grip is tight enough to prevent slippage. An adequate length of cod should be left within the splice box to allow for easy removal for future disconnecting and resplicing. 4. Refer to document EIN-SB-SB-1 for instructions to splice the float wire to the wire from the control panel. Attach the float wires using the waterproof wire nuts. It is necessary to replace this wire not with a new watertight wire out. Always use watertightwire nuts or heat shrink splice kits for all connections! 5. Replace the float and collar and return the assembly to the pump vault. 6. Reconnect power and test the unit. NIN-MF-MF-1 © 2003 Ore are Syster sd Inc.

The range of float cord diam- eters each clip position will clamp is listed below: "L" Clip position: up to 0.35" "S" Clip position: down to 0.28" Use the clip position that holds the cord the tight- est without distorting the clip. The cord should not slip when pulled moderately by hand. Step 3: Securing Float Collar to 1" Schedule 40 PVC Pipe Secure float collars in proper location, using stain- less steel set screw provided in the kit. Tighten the set screw until float collar is firmly clamped. Note: A cord retainer recess is built into the collar. The cords from lower floats can be tucked into the recess, keeping the cords from becoming tangled with floats. Adjusting Float Height Float height can be adjusted by loosening the stainless steel set screw and simply sliding the float collar up or down the float stem. Adjusting Float Cord Tether Length Float cord tether length can be adjusted by remov- ing the clip, adjusting the cord's position, and re- installing the clip.

The filter prevents large solids from leaving the tank, dramatically improving wastewater quality and extending the life of downstream treatment systems. Hach pump vault comes with a Bioarbe filter cartridge, a float stem bracket, and support pipes. It can accommodate either one (Simplex) or two (Duplex) High Head Effluent Pumps, their discharge assemblies, and a float switch assembly, all of which are ordered separately. The unique Notube filter cartridge provides a Loge filter surface area (see specs on bade) in a small space, to resist clogging while providing maxitnu m long-term protection.

Disu�ibuted By: As of 3/15/02, all "dash -L" PVU vaults (PVU vaults with long support pipes) come with a support pipe brace to prevent deforming. Occasionally, duplex pumps used with long support pipes —as well as long support pipes used with big tank openings — pull the PVU vault out of round. To retrofit existing PVU vaults for these "dash -L" applications, use a PVU Retrofit Kit —which includes a support pipe brace and two binding post sa ews—and follow the instructions below. Note: It is not necessary to retrofit simplex vaults used in standard tank openings. And Orenco does not recommend retrofitting installed vaults, unless they are deforming. 1. Remove one of the set screws from each of the gray support pipes and slide the support pipes out of the way. Remove the Biotube" cartridge from the PVU vault. 2. Slide the support pipe brace down between the flow inducer and the cartridge chamber, aligning the holes with the support pipe holes in the cartridge chamber. 3. Slide the support pipes through the support pipe brace holes. This will hold the brace in place. Make sure that the set screw holes for the screws you removed from the support pipes (in Step 1) are on the side of the support pipe brace closest to the flow inducer. 4. Using a 1/4" drill bit, drill two holes through the cartridge chamber, support pipe brace, and flow inducer, spacing the holes as follows: To position the first screw hole, measure from the top of the PVU vault to the top of the support pipe brace (the "x" height in the adjacent drawing) and add 3/4". To position the second screw hole, measure 1 1/2" below the first screw hole. 5. Insert the two binding post screws into the holes and tighten. Turn PVU vault upside down to remove any debris from drilling holes. Replace the Biotube° cartridge back into the PVU vault. 6. Replace the two set screws back into the gray support pipes. If this doesn't give you enough leeway with the support pipes to maneuver the PVU into the tank, drill an 1/8" hole approximately 3" closer to the outer edge of the support pipes, measured from the existing holes, and move the set screws.
