The Next Generation Basin by NDS

Over the past couple years we have posted several articles discussing catch basins and catch basin installation. More specifically, we have found ourselves focusing on the broad selection of catch basin products for yard and downspout drainage manufactured by National Diversified Sales (NDS).

This article is devoted to one of my favorite NDS catch basin products called the Next Generation Basin, or 1200 NGB. The 1200 NGB is a unique 12” x 12” catch basin that allows you to adjust the invert elevations of the catch basin without changing elevation at grade (at the grating). No other residential grade catch basin has this feature!

Take a look at the 1200 NGB catch basin kit (above), which contains two open adjustable wall panels. The round openings in the basin’s wall panels are specifically designed to accept one of NDS’s universal outlets.  So, not only are the inverts for the 1200 NGB adjustable, but it can fit a variety of piping options, too.  In the photo below, a 1243 pipe adapter is shown alongside a panel wall.

If only one outlet is needed for the catch basin, the 1266 plug adapter can be inserted to seal up the wall.  NDS also offers a solid wall panel (or plug side) can be inserted to close the open side (see photo below).  Still, the plug side does offer a knock-out for a pipe adapter if you later change your mind about having an outlet at that location.

The 1200 NGB system was developed to make catch basin installation easier and more convenient. You can see in the photo below that it has three snap off side-outlet options, each changing the slope of drainage slightly. The lowest setting eliminates most sitting water from the basin, leaving less room for a sump to catch debris but draining the quickest. The center setting is the standard and connects with the middle of the catch basin. The highest setting gives the catch basin more elevation for drainage that needs to travel a longer distance. Depending on the situation, each of these outlets can be just what is needed to complete the job.

The 1200 NGB basin also gives you options in bottom discharging. In the bottom of every basin is an adapter knock-out (similar to the plug side knock-out), which can attach to solid a PVC pipe that feeds off your drainage system.  By attaching the bottom outlet to a perforated pipe, you can create a leaching system uses storm water to recharge the ground water.   Small “weep hole” knock-outs are also located in the bottom corners of the catch basin for those who are just trying to rid the basin of standing water.

The fourth option offered by the Next Generation Catch Basin is a total bottom cut-out, which allows the maximum amount of storm water to be put back into the ground. As the ground becomes saturated, excess water reaches the pipe elevation and is taken away in the drainage system. Though this option maximizes the water that remains on site – a popular choice among those interested in water sustainability – it is not the best option next to home foundations.

One of the best things about the 1200 NGB system, though, is the amount of grating options available for it. Standard plastic grating comes in 4 colors: black, sand, green and gray. Also, there are bronze, brass, galvanized steel and cast iron options. Below are examples of the  standard slotted cast iron grating (left) and the black plastic grating (right).

Other ornamental cast iron grating options are manufactured by Iron Age Designs are also available for this catch basin. Below are four gorgeous patterns that are popular in patio and downspout catch basins. Clockwise from the upper left, the pattern names are Interlaken, Locust, Sun and Oblio.

These grates fit perfectly with the 1200 NGB.  What makes the designs so fantastic is how each one incorporates a different image of nature into what would otherwise be a simple work of cast iron. The Interlaken Grate on the top left has a beautiful yet strict design; it must be a representation of the solid form of earth.  On the top right, the Locust Grate provides a breezier feel; the leaf patterns soften the harshness of the material until it seems to flow.  With the grate pictured on the bottom left, the Oblio Grate, you can get a sense of water in the concentric circles; the grate is reflecting the distorted surface of water during a rain.   At the bottom right, the Sun Grate exudes warmth and intensity; the sun seems to pop out of the plain background of circles.   Consider painting this grate in bright colors prior to installation.

Thanks for stopping by our blog to learn about the Next Generation Basin, the catch basin that does what no other residential basin can do!  All of the products mentioned in this article are available from Trench Drain Systems.  Call them at 610-638-1221 or email your inquiry.

Mini Channel’s Decorative Grating Options

National Diversified Sales (NDS) is a plastic trench drain manufacturer based out of California.  They have a fantastic selection of plastic trench drain systems that are used in residential and commercial applications.  The 3 inch-wide Mini Channel is popular because its honeycomb design and inexpensive price appeals to contractors and homeowners.  However, a big part of the drainage system’s popularity comes from the number of complementary grating options offered.

The standard grate offered with the Mini Channel is still a 3 foot long plastic grate, which is offered in six colors (gray, white, green, black, red, and sand).  Gray was the go-to color in the past, but customers are now branching out for colors that blend with the hardscaping; sand and white plastic grates, especially, are gaining popularity.

For those with a more discriminating taste, NDS offers two slotted brass grating options.   The 1 foot long brass grates come in a satin or polished finish. Besides being simple, shiny, and elegant, they contain chamfered holes for optional screw placement, which helps keep the grates secured in the channel.

Another option available for Mini Channel customers is decorative cast iron grates.  These aren’t the ordinary slotted grates of yester-year; the cast iron grating product lines below illustrate the beautiful side of a functional product that was previously considered a necessary – and ugly – evil by many homeowners.  (Note:  these grates are shown with a baked-on oil finish unless otherwise specified but come standard in an unfinished cast iron.)

Currently, five styles of cast iron grates work with NDS’ Mini Channel system: the Acanthus, Interlaken, Carbochon, Locust and the Minnione.  There are a few basic differences between these four Mini Channel grates.  The Interlaken is an intricate geometrical pattern while the Minnione has a flowing design.  The Locust pattern evokes the feel of leaves blowing in the wind.  Meanwhile, Carbochon’s open area is only accentuated by its bold pattern.

Style aside, the most noteworthy difference in the grates is length. The Interlaken (11″ long) is an inch shorter than the Minnione and Locust grates (12″ long).  The Carbochon (14” long) outdoes all three grates by inches.  I think the length of the grates is important because it determines what you can do with the design of the run.  Unfortunately, it is often overlooked during the planning stage and leads to extra work later on.

Another difference in the grates is how they fit into the Mini Channel.   Take a look at the photo above. Minnione, the thinnest grate, does not rest in the channel with the same depth that Interlaken, Locust and Carbochon do.  While the other grates are cast with tongues that fit snugly into the Mini Channel’s patented “flying buttress” lip, one gets the feeling that the Minnione sits on top of the drain rather than resting inside it.

The foundry uses cast iron as the standard material when making these decorative grates but also manufactures cast brass, bronze and aluminum grating for an additional cost. We should note that cast iron grates are uncoated (raw) and will form a rust coating over time.  The rusting process, when reproduced artificially to save time, is called a baked-on oil finish.  I find the resulting patina charming.

If your application doesn’t support this view, though, consider painting with an epoxy or powder coating. The powder coating process smoothes out the natural texture of the cast iron grates, giving them a softer, less metallic look.  You can really feel the difference between the painted and baked-on oil finishes; the process encased these grates in paint rather than changing their outer layers.

Let me just demonstrate the difference between the two available finishes in another way.  Look at the Interlaken grates shown below:  in terms of color, they are very similar.  But, if you look closer you can see the different shine, the thickly coated surface of the grate on the right.  It’s been powder coated.  The grate on the left, though, has a baked-on oil finish.   I’ll leave you to decide which one you like better.  For additional information on cast iron grating finishes, visit our “Cast Iron Finishing Options” blog.

Cost is all in a person’s perspective, especially when talking about trench drain products. A simple plastic grate that comes in six basic colors is available for a very low price per foot. NDS’ brass grate, a beautiful, no-hassle solution for those still worried about rust or decor, is the most expensive. The cast iron grates, which add style and variety, come for the more moderate price that falls somewhere in between and have beautiful finish options. They are the true extra mile, the art to efficiency, and are the balance if a cost-efficient and stylish grate is desired.

NDS 8″ Pro Series Channel Drain

Recently, a number of people contacted us regarding the NDS 8 inch Pro Series Channel Drain. In a previous article, the 8” Pro Series was mentioned, though not in any great detail. In this article, I’ll elaborate on the channel and grating features this popular channel drain system.

The Pro Series by NDS

The Pro Series is a family of plastic channel drain products manufactured by National Diversified Sales (NDS) under licensing agreement from First Plast S.R.L. (Italy). There is a similar product line in Brazil made by Tigre Plastics that may be licensed under an agreement with First Plast, as well.

These injection molded channels are made with PVC containing ultra violet light inhibitors to help prevent fading and cracking. Pro Series channels are neutral (non-sloping), reinforced with ribbing every 4 inches and come in widths of 3”, 5” 8” and 12”. Options on grating, channel length, corner sections and outlets differ between the various width products.

However, each Pro Series channel features a unique, interlocking end joint connection. The reinforcement ribbing doubles as a cutting point (in the event that the channel needs to be shorted) which maintains the interlocking end joint connection. These features help make the Pro Series product line a smart, affordably drainage system for residential applications.

8” Pro Series Channel Details

The 8” Pro Series channel is used in applications where rain water accumulates rapidly or in applications requiring a larger runoff reservoir than is offered by the smaller Pro Series products. Technically speaking, the 8” Pro Series is named for its  width, which is actually 7.875 inches wide. The channel width, or throat, is about 6 inches wide. All channel lengths are ½ meter (20 inches) and are available in shallow or deep profiles (shown below).

The 8” shallow channel is about 4 ½ inches from the top of the grate to the bottom of the channel. Each shallow channel will hold 2 gallons under static conditions (no flow). The 8” deep profile channel, in comparison, is 7 ¼ inches in height and will hold 3.5 gallons under no-flow conditions. The amount of runoff water that these drains will effectively handle depends on the length of the drain, the diameter of the pipe used to drain the system, the pitch of the channel and the size of the openings in the grate used with the system. NDS has technical data that can be used to design a trench drain system capable of withstanding rainfalls typical to your geographic location.

8” Pro Series Outlet Options

Both the shallow and deep profile channels have end caps that can double as a 3” or 4” sewer and drain pipe connections. (See Below) These end caps have knock out sections of plastic that enable water to flow out or in. The shallow profile channel has an additional fitting that allows 3” or 4” S&D pipe to be attached to the drain from the side or the bottom of the channel. The deep profile channel doesn’t have this option. Again, there are knock out plastic sections that cover each of the pipe attachments on this special outlet.

8” Pro Series Grating Options

NDS sells 4 grating options for the 8″ Pro Series. Each grate is 7 ¾ inches wide, 19 5/8 inches long and ¾ inches deep. You will need to have one grate for every section of channel, as they are the same length. Each grate is connected to the channel by 4 stainless steel screws (sold separately).

Two of the most common 8” Pro Series grates are shown below. The top grate in this photo is a pedestrian rated perforated grate (Part No. 836) which is ADA compliant and can drain 15.33 GPM per linear foot of grating. The bottom grate is the standard light traffic slotted grate (Part No. 837) that has over twice the draining capability of the perforated grate. Both grates are made of high impact Polyolefin and are light gray in color. Not shown in this photo is a glass reinforced nylon slotted grate (Part No. 838), which is said to be able to withstand heavy truck traffic while also being ADA compliant.

Two cast iron grates are available for the 8” Pro Series. These are shown below. The black slotted grate (Part No. 888) is made by NDS, has 54 GPM drainage capability per linear foot of grating and is able to withstand truck traffic. The decorative grate beneath the slotted grate is called the 8” Carbochon and is made by Iron Age Designs. This grate was specifically designed to fit the 8” Pro Series channel, is made of ductile iron, is ADA compliant and has a higher open surface area per foot than any of the NDS grating options.

The Carbochon grate isn’t supplied with bolt-down holes or a protective coating to prevent rust. However, the aesthetics and pricing of this Ironage product make it an attractive option to the standard slotted cast iron grate. The Carbochon grates are available from Trench Drain Systems and can be purchased with an oil-baked finish or a custom epoxy coating.

Pro Series Installation Features

The Pro Series channels have three useful installation features that are common to all available sizes. These are illustrated in the photo below.

Pro Series channels have a unique interlocking channel design that is the key to their modular system success. This “tongue and groove” design allows each channel to securely lock to the adjoining piece. The “male” end of the channel easily slides into the “female” side of the adjoining channel when adding length to the drain. This connection joint can be made stronger by using PVC cement at the contacts prior to locking the channel together.

Another key feature that makes the Pro Series a unique modular system is the reinforcing ribs. Not only do the ribs give the channel walls rigidity, they are designed to be a cutting point for channel shortening while still keeping the “male” end of the channel that is necessary for attachment. No other trench drain system on the market has this feature.

Each channel also has “feet” that can be used as a rebar attachment site during installation. Generally, rebar is hammered into the ground at the foot locations. Wire is then wrapped securely around the rebar and channel foot. Final adjustment can be made to the channel to ensure the top of the drain is set to the desired elevation prior to pouring concrete. Instead of rebar, wood stakes can be used. In this case, wood screws can be used to firmly attach the channel foot to the installation stake.

Summary

In summary, the NDS 8″ Pro Series is a high volume channel drain for residential applications. The wider channels help insure that water is quickly removed from hardscapes. The unique design of the Pro Series facilitates ease and speed of installation. Grating options are comparatively meager, but growing due to the new selections becoming available by Iron Age Designs.
