JM Eagle offers the most comprehensive line of plastic pipe. endobj Use Table 1.1 below to determine the Rainfall Intensity (I) of the property. 4 0 obj Pacific Corrugated Pipe Company is now part of the Lane Enterprises family. 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. 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. In this case, you would need to use 4 pipe for the drainage system. 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. stream 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. 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. 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. endobj )^U=(zFW/J}=*|ivK{HKwa+&-WgsM-P Q = peak runoff flow (gallons per minute) Fits 3 pipe attaching directly to PVC collar or fits 4 pipe via 4 S&D fitting. 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. 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).

The only time a decision needs to be made is when using a 6 round or 6 square grate. Cost efficiency and ease of installation make PVC and PE the materials of choice for top contractors. Let our company owners/ industry professionals deliver on the service and quality you deserve! endobj There are 2 common types of fittings that can be used. Locate the low spots on the property where excess water could accumulate. The distance from the backyard to the street is 100. <> endobj These fittings snap directly onto the drainage pipe. x[k0QDnpe=?M%H)? \\Lvy W_?3p0og8r_iACG,g jCvk t_QY$J3;tOwx@ " Because of its rigidity, the trench bed slope and smoothness is even less critical than with the Sewer and Drain pipe described above. 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. 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. C = coefficient of runoff The Rational Method Formula is: Once you have calculated each grates flow requirements, use Table 6.1 below to select the grates. See how our commitement to excellence has impacted our customers. In other areas however, grate colors are more a matter of personal preference. We were selected to deliver the CM and R project, Crossroads East Drainage infrastructure. There are many options for re-routing the water that is collected in the grates and piping. Lastly, we will use the Rational Formula to calculate the peak runoff flows for each area. Tempos grates are designed to be used with all of them. (Minimum recommended slope should be 24 per 100 ft or approximately 1/4 per foot). I have found that Pacific Corrugated Pipe Co has an outstanding response time in getting the quotes back. stream Because they are plastic, they will not corrode, ensuring no harm will come to the environment or its inhabitants. In our example, the ends of the drainage pipes will be cut flush with the street curb so no additional parts are needed. When using the 9, 12 and 18 grates a catch basin or low profile basin must be used. I = rainfall intensity (inches per hour) Highland Ave.Hollywood, CA 90038Phone: (323) 464-1600. Therefore an atrium grate (Grate 1) is recommended. Single Wall corrugated fittings are used to couple the drainage pipe and change directions. We were acquired by Lane Enterprises in 2021 and are now an employee-owned company. We were very pleased with the savings we would be realizing on the material alone. 5 0 obj Next, we will determine the coefficient of runoff (C) for the surface type of each area to be drained using Table 2.1 below. For the concrete deck area, a flat grate (Grate 3) must also be used. For optimum results this slope should be fairly uniform. The 3 atrium grate that you had previously chosen would not have been adequate and a 4 atrium grate would be required. endstream 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. 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. 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. where: <> For our example, we already know the area (A) of each zone to be drained. 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. 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. Triple Wall Pipe is similar to the above but has a heavier wall and is thus sturdier. After the evaluation of two products, we determined the Spiral Rib to be the most economical hydraulically efficient choice for this project. 2 0 obj Sewer and Drain PVC hub fittings are used to couple the drainage pipe and change directions. These grates can either be plumbed inline or have two separate 3 drainage pipes that are later connected into a single 3 discharge pipe. 0|JY@pA Tnk&+Ej 3qJFF 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). Two separate 3 or larger pipes with two discharge points could be used (a two Zone Drainage system).

Thanks for the great work, we have been purchasing corrugated steel pipe from Pacific Corrugated Pipe Company for well over 20 years. When our team met with Pacific Corrugated Pipe we became aware of the potential of utilizing Spiral Rib Pipe. In our example, all three can indeed be used with 3 pipe. 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.). The most popular and readily available fittings are straight couplers, 90 degree elbows, 45 degree wyes, tees and end caps. Adding these together, the total combined area maximum runoff flow (Q) is 49.1 gallons per minute. There are no catch basins available for 3 or 4 grates as they connect directly to drainage pipe. There are 2 options for the 3 piping network for the grass and flowerbed areas. You responded promptly to all of my inquiries Thank you for making my firstexperience with your company a positiveexperience, Thank you again for bringing out our shelter.

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. 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. For the concrete deck: Q = (0.90 x 5.0 x 800) / 96 = 37.5 gallons per minute. For the grass: Q = (0.35 x 5.0 x 480) / 96 = 8.8 gallons per minute Through a series of events, this project was delayed from its original start date of May 2019 to October 2019. Note: There are three common types of drainage pipe and fittings that are used.

Flat grates are typically used in areas where there is pedestrian, wheelchair, or light duty auto traffic. It also requires Sewer and Drain hub fittings to make directional changes. 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. That is really fast! This company has consistently provided the greatest value in terms of both the materials cost and the service Ive received. Let us assume that for this project, the run-off water will be re-routed to the street curb. Our mission at Pacific Corrugated Pipe is to: deliver the most attentive localized customer service imaginable; produce the highest quality products; and to offer the quickest turnaround all at a fair price. Corrugated Pipe is flexible and typically can make directional changes without the need for fittings. This pipe needs Sewer and Drain hub fittings to make directional changes and joins. The flowerbed is 120 sq feet, the grass area is 480 sq feet and the concrete deck area is 800 sq feet. Be generous in the design-if in doubt add an extra collection point (grate) and rather oversize than undersize a component. A contractor needs to install a drainage system in the backyard of a house in Atlanta, Georgia. In our example, a catch basin must be used for the 6 grate because we are connecting it to a 3 pipe. Fits 2 Schedule 40 pipe attaching directly to PVC collar or fits 3 pipe via 3 S&D fitting. Fax: (949) 650-0781, [javascript protected email address]/*/Metadata 625 0 R/ViewerPreferences 626 0 R>> The advantages of this type of pipe are its flexibility and its ease of installation. 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. -/X]oo'}+Kza.#PMDDDI|1 2:#r#Dt]2. Once these are finalized, they become the basin and/or grate locations. 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. 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. !7^qde,J ,6$2fEJ2YMHE(MaiEh. |e{'W%fUO:*78+7xM;hpz?Vc+ The backyard is comprised of 3 areas, a loamy soil flower bed, a grass area and a concrete deck. 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. 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. The most commonly used grate color for grass areas is green. Different parts of the country have varying rainfall intensity profiles.
