Trench drains are beneficial for controlling floor water earlier than they can saturate the floor. In contrast, French drains seize and ship groundwater and surface water from a unique area to a septic tank or fantastic drainage device. If you are concerned about water on the surface, a trench drain is possible.
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.
Swales: A Natural Solution
They're a great option if you're looking for a more natural, eco-friendly alternative to French drains. A swale is typically lined with grass or vegetation that helps slow down and absorb water.
Ultimately, if you are dealing with groundwater or basement flooding, a French drain is your best bet. If your issue is surface water pooling, especially in paved areas, a trench drain is the way to go.

French Drains
The perforations in the pipe allow water to seep into the drain, and the gravel helps to filter out any debris. The soil on top helps to keep the gravel in place and also aids in the absorption of water. French drains are an effective way to reduce flooding and prevent water damage.
Surface water discharges into highways drains and gullies and these can sometimes become blocked by leaves, litter, silt and waste. Water is unable to drain away quickly enough which leads to flooding.
Point Drain or Linear Drain
Point drains are most common and are what we are used to seeing in showers. They are typically located in the middle of the shower floor, and the floor is sloped from all directions down to the drain.
Clay soil has poor permeability, meaning it doesn't allow water to pass through easily. In such cases, the effectiveness of a French drain may be limited as the water may struggle to drain away from the area efficiently. French drains may not be suitable for areas with high water tables.
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.
Interior French drains are meant for waterproofing the basement or draining your crawl space. They cost more because contractors must tear out the basement floor (most often made of concrete), install the drain, and then repair it.
An interior drainage system is an easier, more affordable option for waterproofing your basement. The WaterGuard Basement Waterproofing System is a non-clogging French drain alternative. Our interior drainage system captures water at the most common point of basement entry - the floor and the wall joint.
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.
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.
A traditional trench drainage system, also known as a linear drain or channel drain, is a widely used and highly effective method for managing surface water and preventing water-related issues.
French Drains. If the problem area spans across a much larger area, a French Drain would be a more effective solution. The advantage of using a French drain is that it can be laid out underneath an entire area and allow for this surface water to be managed underground.
The average cost to install a yard drainage system is $4,617, but this project can range from as low as $800 for small-scale fixes to $15,000 for full-scale solutions. The average cost to install a drainage system in a yard is $4,617, though most homeowners spend between $2,120 and $7,114.
Corrugated Pipe Provides More Flexibility Than PVC
That's why selecting the correct drainage materials for your yard is imperative. Solid corrugated pipe expands when ice backs up in the line and contracts during the thaw to move moisture away from the house.
Trench drains require regular cleaning of the grates to prevent clogging and ensure optimal performance. Slot drains have minimal maintenance requirements due to the absence of grates, making them easier to clean.
With stormwater, most likely, your drainage systems would fall under land improvements. Stormwater best management practices such as french drains, downspouts and gutter systems, bioswales, and dry wells could qualify as depreciable assets.
French drains (aka weeping tile, perimeter drains, agricultural drains, and rock drains) are an easy-to-install solution for your drainage problems. Clients pay an average price of $5,000 to have a French drain installed professionally, with most homeowners paying $1,650 – $12,250.
Clogging and Blockages
Clogging is one of the leading causes of French drain failure, often due to root intrusion or sediment build-up.
