Two main types include the concrete trench drain and the high-density polyethylene (HDPE), or polymer, trench drain.
Swale Drain System
Swale drain systems are lesser known surface systems that are more broad and shallow than trench drains, making them a more subtle option. A swale drain is essentially a ditch that gets covered or lined with either grass or another type of vegetation.
In some cases, the materials chosen matter greatly, with some better suited than others or required by law. One universally accepted material is stainless steel, which is safe for many applications. As a result, stainless steel trench drains have become one of the best types of drainage systems.
The ditch is the area in which the trench drain is poured. Concrete, dirt, gravel asphalt can be used.
As discussed, there are two major groups of trench drains. Polymer Channels and Concrete Channels. Polymer based channels can come in the form of hdpe (high density polyethylene) or fiberglass. Concrete based channels can come in the form of fiber reinforced concrete or polymer concrete.
Drainage interceptors or drain separators are a defence to stop contaminants from entering surface water drains. Also referred to as petrol interceptors or oil separators, they are tanks installed within drainage pipework designed to collect and keep hold of contaminants.
The primary function of trench drains is water management. These structures gather and move rainwater to a drain or another outlet, preventing water from building up. This function is crucial for maintaining dry and safe surfaces, reducing the risk of slips, flooding, and water damage.
Aside from what we've listed here, the difference between a French drain and a trench drain is that a French drain is used for water that is underground while a trench drain diverts excess water from a surface.
TRENCH DRAIN CONS:
Heavy forklifts and other equipment can damage the grates. High flow rates into the drain can result in splashing, causing contamination. The wider opening, though covered by a grate, can create a tripping hazard.
Conclusion. P-traps assume an indispensable role in the efficient operation and safety of trench drain systems. By effectively acting as barriers against foul odors, sewer gases, and potential contaminants, P-traps ensure a healthy, odor-free environment while preventing the spread of harmful substances.
Radius Trench Drain
This is a complex drain design that allows the drain to follow a curve in a walkway or around something like a fountain. This kind of drain is usually about 2” to 24” in width and can be ornamental or plain. This drain type will typically cost anywhere from $30 to $150 per installed foot.
This part of drain maintenance is most commonly required for business locations, but even residential trench drains need to be cleaned out a few times a year on average. When trench drains are not cleaned up regularly, they can get clogged and lead to standing water or even damage to the drain system itself.
Directional drilling, also known as horizontal directional drilling (HDD) or directional boring, is a trenchless method that involves drilling a pilot hole along a predetermined path, followed by enlarging the hole to accommodate the utility conduit, which is then pulled through the opening.
A French drain is a practical solution for managing water around your property, especially in areas prone to heavy rain and water accumulation. This drainage system helps prevent issues like standing water, soil erosion, and even basement flooding by redirecting water away from vulnerable areas.
Backfill the Trench With Concrete
To ensure the drain channel is secure, you want to do this process in two steps: first, floating the channel 1/16-inch below the first layer of concrete. Then, once it has set, backfill the rest of the trench with at least 4-inches of concrete on both sides.
Continuous trench drains for gas or oil discharges shall have a trapped and vented opening no less than every 40 lineal feet. Intermittent trench drains shall be treated as individual floor drains and shall meet the trap and venting requirements for floor drains.
A properly designed trench drain will last for 25-50 years or longer. The wrong trench drain will often fail in 2-5 years, and sometimes, even sooner.
The slope of the drain makes sure that the drain can work effectively, and it prevents issues with pressures on the trench that can lead to its failure. The outlets on the channel will need to point in the direction of the water flow, and the outlet end will need to be placed at the end of the slope of the drain.
A soakaway consists of a hole dug in the ground and filled with rubble or plastic crates. It provides a solution to excess surface water by letting it slowly drain and soak into the ground instead of build up.
The Amerimax Stealth Drain Low Profile Catch Basin allows you to move damaging rainwater away from your home with the look of a buried drainage system, without the cost. The low profile design creates an unobtrusive look and can be covered with mulch, straw or stones for a subtle appearance, with no digging required.
Drainage Interceptor Traps
They come in many shapes and sizes and the same shape of trap may be known as a Bristol trap or a Blackpool trap and no doubt a Great Budworth trap if that's the part of the country you are in.
A chase drain is a metal drain placed within the sidewalk to direct water flow through the sidewalk instead of over it.
