n used with concrete application

When used with concrete applications, grey grates may be the most appropriate color. In addition to meeting the required specifications, our pipes go through extensive testing to ensure they can maintain their quality and performance over time. Pacific Corrugated Pipe Company is now part of the Lane Enterprises family. |e{'W%fUO:*78+7xM;hpz?Vc+ Copyright 2022 Pacific Corrugated Pipe Company, All rights reserved. If there is more than one low point within an area, each of these would be a collection point and a location for a basin and/or grate. If the natural topography of the area to be drained does not have the necessary fall to meet the minimum slope requirements, you will need to dig a trench with the minimum slope required and then use a combination of low profile basins and catch basins, some of which will have one or multiple risers to make sure that grates end up at grade level. The 3 atrium grate that you had previously chosen would not have been adequate and a 4 atrium grate would be required. Using either 3, 4 or 6 drainage pipe is recommended on most residential and light commercial projects as these pipe sizes and applicable fittings are readily available and easy to install. The most popular and readily available fittings are straight couplers, 90 degree elbows, 45 degree wyes, tees and end caps. We were acquired by Lane Enterprises in 2021 and are now an employee-owned company. The most commonly used grate color for grass areas is green. The first basin and/or grate is located in the flowerbed, the second basin and/or grate is in the grass area and the third basin and/or grate is in the concrete deck. This is going to be a wonderful exhibit, in no small part due to your help and exceptional service, I want to take a moment to thank you for all your efforts for prompt delivery of this commodity, and would gladly recommend you for future endeavors. Next, we will determine the coefficient of runoff (C) for the surface type of each area to be drained using Table 2.1 below. I have found that Pacific Corrugated Pipe Co has an outstanding response time in getting the quotes back. See how our commitement to excellence has impacted our customers. <> However, if say the flowerbed area had been 600 sq ft instead of 120 sq ft, the Rational Method formula in Step 2 would have increased the maximum runoff flow from 2.8 GPM to 14.1 GPM. These fittings snap directly onto the drainage pipe. This company has consistently provided the greatest value in terms of both the materials cost and the service Ive received. Use Table 1.1 below to determine the Rainfall Intensity (I) of the property. Ive always been happy doing business with the sales team at PCP because they are friendly, professional, and take care of our needs in a timely manner, I want to take a moment to commend you on the level of service you afforded me. xKI3;|GA 6sb{s`dPXfu0a,0:bc Fax: (949) 650-0781, [javascript protected email address]/*\"+d+\"\"")/*]]>*/, I wanted to send this letter as a thank you to the Pacific Corrugated Team for assisting in delivering excellent customer service to our client, City of Scottsdale. In our example, all three can indeed be used with 3 pipe. For the concrete deck: Q = (0.90 x 5.0 x 800) / 96 = 37.5 gallons per minute. !7^qde,J ,6$2fEJ2YMHE(MaiEh. There are three common types of drainage pipe to use. )^U=(zFW/J}=*|ivK{HKwa+&-WgsM-P There are 2 options for the 3 piping network for the grass and flowerbed areas. Lastly, we will use the Rational Formula to calculate the peak runoff flows for each area. As the property in our example is in Atlanta, GA, it falls into Rainfall Intensity Zone A with a Rainfall Intensity of 5.0 inches per hour. }#Jt2-9#S "N Cgfpy ku8\uC;VzlPn[f]9RP9rVnsk-%AJdy2BtGPR%}Md,DzG`l&u$iW9$w*Ch1N0'dsjuX9m);K9;4eTe'}n\K?WW`iCZ`l?7Sv"=D79;R'8tGfCz.C"pJF# KlD(+9 NZK?&%6'>1!5 M*K} There are many options for re-routing the water that is collected in the grates and piping. For optimum results this slope should be fairly uniform. In the previous example problem, assume that the flowerbed has been mulched and leaves may also be present. We were very pleased with the savings we would be realizing on the material alone. Because of its rigidity, the trench bed slope and smoothness is even less critical than with the Sewer and Drain pipe described above. Thanks for making that delivery on the 23 rd instead of the 29 th , that is going to make some people really happy! We were selected to deliver the CM and R project, Crossroads East Drainage infrastructure. Some of the most common applications for re-routing the water are to the street curb, to a storm water drain, to another landscaped area that can safely handle large volumes of water, to a French drain or to a storage tank that would allow for irrigation at a later time. Fits 2 Schedule 40 pipe attaching directly to PVC collar or fits 3 pipe via 3 S&D fitting.

The backyard is comprised of 3 areas, a loamy soil flower bed, a grass area and a concrete deck. I have recommended that all the Engineers in our department to use PCP when preparing their quotes. After careful examination of the structural calculation, independent test reports, case histories, ASTM & AASHTO specifications, and all the other agency approvals, we have concluded that Spiral Rib Pipe would be an excellent alternative to cast in place of reinforced concrete pipe on our storm drain projects. 2 0 obj In our example, the ends of the drainage pipes will be cut flush with the street curb so no additional parts are needed. endobj stream Keep in mind that the table below has been simplified (more sophisticated data is available on the web that contain 100 year one-hour rainfall maps, etc.). Thanks for the great work, we have been purchasing corrugated steel pipe from Pacific Corrugated Pipe Company for well over 20 years. After the evaluation of two products, we determined the Spiral Rib to be the most economical hydraulically efficient choice for this project. As we previously decided to use all 3 drainage piping, check on Table 6.2 below that all of the grate sizes chosen can be used with 3 pipe. For the example we are using, as 3 pipe is easier to install and cheaper than 4 or 6 pipe, we will select a two Drainage Zone system using 3 pipe with two independent discharge points. endobj The advantages of this type of pipe are its flexibility and its ease of installation. Let us assume that for this project, the run-off water will be re-routed to the street curb. If you still preferred to use 3 pipe, then a suggestion would be to use two adjacent 3 atrium grates (each grate would then handle just over 7.0 GPM which is within its maximum capacity of 12 GPM). As a new customer to PacificCorrugated PipeI was fortunate to have been directed to you. However, in many cases the drainage pipe terminates on the property and it is best to close it off with a grate or a pop-up relief valve to prevent debris or rodents from entering. In Table 7.1 below, you can see the different color options available. endstream Michael C Testimonial | Haydon Building Corp. Don't take our word for it. After modifying a delivery date to a much earlier date and finding a creative way to meet this customers new deadline we received this note from one of our awesome customers: Oh awesome! Because they are plastic, they will not corrode, ensuring no harm will come to the environment or its inhabitants. When our team met with Pacific Corrugated Pipe we became aware of the potential of utilizing Spiral Rib Pipe. The flower bed area is 6 wide x 20 long (area of 120 sq ft), the grass area is 20 wide x 24 long (area of 480 sq ft) and the concrete deck area is 40 wide x 20 long (area of 800 sq ft). Locate the low spots on the property where excess water could accumulate. Let our company owners/ industry professionals deliver on the service and quality you deserve! <>/Metadata 625 0 R/ViewerPreferences 626 0 R>> Adding these together, the total combined area maximum runoff flow (Q) is 49.1 gallons per minute. A contractor needs to install a drainage system in the backyard of a house in Atlanta, Georgia. Note: There are three common types of drainage pipe and fittings that are used. In our example and using Table 3.1 above, there are two choices to accommodate the maximum property run-off flow calculated in step 2 of 49.1 GPM. JM Eagle 5200 West Century Boulevard Los Angeles, CA 90045, For a Special Report on US Infrastructure Investigation Update Quality Assurance Global Outreach Energy Star Partner US Green Building Council member. There are no catch basins available for 3 or 4 grates as they connect directly to drainage pipe. Excess water always collects at the lowest elevation points. 5 0 obj 19800 MacArthur Blvd, STE 510 I am a loyal customer and plan to work with Pacific Corrugated well into the future. For our example, we already know the area (A) of each zone to be drained. For the grass area, a flat grate (Grate 2) must be used as there will be lawnmower and foot traffic present. endobj West Los Angeles Location11060 W.

A frequently used formula for calculating the maximum runoff potential from a small area (under 200 acres) is the Rational Method. C = coefficient of runoff <> The only time a decision needs to be made is when using a 6 round or 6 square grate. Fits 3 pipe attaching directly to PVC collar or fits 4 pipe via 4 S&D fitting. Because of its smooth wall, it is easier to clean and the trench bed slope and smoothness is less critical as this pipe will somewhat compensate for peaks and valleys. Two separate 3 or larger pipes with two discharge points could be used (a two Zone Drainage system). Highland Ave.Hollywood, CA 90038Phone: (323) 464-1600. That is really fast! Corrugated Pipe is flexible and typically can make directional changes without the need for fittings. In the example above, let us assume that each of the 3 areas described has a single low point within its confines. Please refer to the Appendix at the end of this guide for more information on the different types of drainage pipes and the appropriate fittings. Once you have calculated each grates flow requirements, use Table 6.1 below to select the grates. When using the 9, 12 and 18 grates a catch basin or low profile basin must be used. 0|JY@pA Tnk&+Ej 3qJFF Although obvious, water can only flow downhill. Using the maximum runoff flows from each area that we calculated in Step 2, divide each areas flow by the number of grates locations in that area to calculate how much flow each grate needs to handle. For the concrete deck area (with only one grate location) and a maximum runoff flow of 37.5 GPM, we choose a 9 flat grate which has a maximum flow rate of 50 GPM. x[k0QDnpe=?M%H)? \\Lvy W_?3p0og8r_iACG,g jCvk t_QY$J3;tOwx@ " I = rainfall intensity (inches per hour) Flat grates are typically used in areas where there is pedestrian, wheelchair, or light duty auto traffic. The flowerbed is 120 sq feet, the grass area is 480 sq feet and the concrete deck area is 800 sq feet. The disadvantages are that it is hard to clean out (because of the corrugations), the connections are not very watertight and that the trench bed has to be very carefully sloped. 4 0 obj Sewer and Drain PVC hub fittings are used to couple the drainage pipe and change directions. JM Eagle offers the most comprehensive line of plastic pipe. Different parts of the country have varying rainfall intensity profiles. Remember that the water must flow only downhill (even a small uphill section will prevent your system from draining properly). The 3 grate will connect directly to 3 pipe, the 6 grate will connect to the 3 pipe using a 6 catch basin and the 9 grate will connect to 3 pipe using a 9 catch basin. As the distance that the run-off water needs to travel is 100 ft, the recommended elevation drop from any grate to the discharge point must be a minimum of 2 or 24. Once these are finalized, they become the basin and/or grate locations. The coefficient of runoff for the loamy soil flowerbed is 0.45, for the grass area is 0.35 and for the concrete deck area is 0.90. -/X]oo'}+Kza.#PMDDDI|1 2:#r#Dt]2. Q = peak runoff flow (gallons per minute) The plumbing for the drainage pipe from the concrete deck area will be a single 3 pipe that runs from the 9 basin to the discharge point. However, if 4 or 6 pipe is more readily available than 3 pipe, you may choose to use that instead. <> We also appreciate naming your company as a Trade Reference for (our company) , For over 15 years Pacific Corrugated has provided our company with drainage products, industry expertise, fast service, competitive pricing, and professionalism on every project that we sourced from Pacific Corrugated.. When designing a drainage system, attention must be paid not to exceed the maximum flow capacities of the drainage pipe (as show in Table 3.1 below).

(Minimum recommended slope should be 24 per 100 ft or approximately 1/4 per foot). For the grass: Q = (0.35 x 5.0 x 480) / 96 = 8.8 gallons per minute In our example, a catch basin must be used for the 6 grate because we are connecting it to a 3 pipe. Whether its our Polyvinyl Chloride (PVC) or Polyethylene (PE) pipes, JM Eagle products are the very best for their applications. where: Single Wall corrugated fittings are used to couple the drainage pipe and change directions. For the grass area (with only one grate location) and a maximum runoff flow of 8.8 GPM, we choose a 6 round flat grate which has a maximum flow rate of 16 GPM. This pop-up relief valve sits flush with the surrounding area and only pops up to allow excess water to discharge when the drainage pipe is full. stream 3 0 obj These fittings are solvent welded onto the pipe. Tempos grates are designed to be used with all of them. For the flowerbed: Q = (0.45 x 5.0 x 120) / 96 = 2.8 gallons per minute These grates can either be plumbed inline or have two separate 3 drainage pipes that are later connected into a single 3 discharge pipe. Through a series of events, this project was delayed from its original start date of May 2019 to October 2019. Thus creating a competitive situation & ensuring the Town of Florence the best value for tax dollars spent.", You guys are great! Atrium grates are domed and typically used where there is no pedestrian traffic and where mulching, leaves, or other debris could be present that could plug the flat grate. In this case, you would need to use 4 pipe for the drainage system. Sorry my stuff is always last minute rush stuff. Therefore an atrium grate (Grate 1) is recommended. ijPkNw(Mu2~/r/3^ no$!"~^Ai*dFkEX25F/5C qmGZmB hw}KIuDO#"@+C\)dSw <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> The most popular and readily available 3 and 4 fittings are straight couplers, 90 degree, 45 degree and 22.5 degree elbows, straight and sanitary tees, 45 degree wyes and end caps. endobj Design for worst case conditions and not for average conditions. For the concrete deck area, a flat grate (Grate 3) must also be used. In the example, for the flowerbed area (with only one grate location) and a maximum runoff flow of 2.8 GPM, we choose a 3 atrium grate, which has a maximum flow rate of 12 GPM. Triple Wall Pipe is similar to the above but has a heavier wall and is thus sturdier. In order to correctly size the drainage pipe network, the maximum run-off flow for each area must be calculated. Drainage Zone 1 will comprise the flowerbed area and the grass area (maximum run-off flow for that combined area is 11.6 GPM) and Drainage Zone 2 (maximum run-off flow is 37.5 GPM) will comprise the concrete deck area. A = drainage area (square feet). They are easy to discuss issue with and are very detailed in taking ours orders. It also requires Sewer and Drain hub fittings to make directional changes. There are 2 common types of fittings that can be used. , I have used corrugated pipe and other companies for obtaining culverts prices for our contacts for the last four years. In other areas however, grate colors are more a matter of personal preference. As a result, the installation of a more than a thousand feet of, I have been purchasing culverts from Pacific Corrugated Pipe Company for the last 13 years. Be generous in the design-if in doubt add an extra collection point (grate) and rather oversize than undersize a component. A single 4 or larger pipe may be used (a single Drainage Zone system). This pipe needs Sewer and Drain hub fittings to make directional changes and joins. Sewer and Drain Pipe is a thin walled PVC pipe.
