Whenever planning to install new or modify an existing buried downspout drain, you need to be very aware of solid debris that can easily enter your buried drainage system and cause future problems. Whether it’s leaves, small branches, tree acorns/seed, asphalt roof shingle granules or any other debris that can enter your downspout by way of unprotected/uncovered gutters, a buried downspout drain system will eventually fail unless certain precautions are taken.
Here are 5 tips to ensure a trouble-free buried gutter downspout drain system.
1). Create an air-gap below your downspout (between downspout outlet and catch basin inlet). It is always a good idea to leave a bit of space (1″ to 4″+/-) between the end of your downspout and entry point of buried drain system to allow water to escape downspout if in the event your buried drain system becomes inoperable. We have seen many poorly designed buried downspout drains over the years that were direct connected (no air-gap) and eventually became clogged due to a lack of regular maintenance or by having no debris protection (atop roof gutters and/or atop buried drain inlet).
2). Reduce entry of large debris into buried drainage system by installing a grate covered catch basin at inlet point (ground level). Not only will most large sized debris get stopped from entering buried drain system via catch basins grate cover, but smaller sized debris that manages to pass through will settle to bottom of catch basin (instead of inside pipe) where it can be easily removed at some point in the future.
3). Add a catch basin filter for extra protection against unwanted small granular sized debris from entering into buried drain pipe.
4). Clean sump base of catch basin (and optional filter) annually to ensure long term buried drain system success. Most downspout catch basins can be easily cleaned out by simply unscrewing the top grate cover and shoveling out or vacuuming any/all settled debris that has accumulated in sump of catch basin.
5). Occasionally inspect top of catch basin (once per month recommended) to ensure the grate cover is free and clear of debris.

If proper site drainage is lacking at your property and continuous rains routinely cause the ground to become fully saturated, standing water will almost certainly occur.
Especially across low lying lawn and poorly drained plant bed areas, if surface water is left to stagnate for long periods of time, non-tolerant plants may fall victim to the negative effects of excessive soil moisture (root decay/wet-feet).
Here are a few ways to relieve standing water at your property.
Redirect existing roof downspouts and/or sump pump outlet pipes to flow toward alternate non-problematic areas (if possible).
Raise the soil grade within low-lying flood prone areas.
Install an underground drainage system to properly relocate, store and/or further improve the natural process of ground water percolation.
Fine tune your irrigation system to prevent over watering (soil type and natural rainfall frequency dependent).
If you suspect a neighboring property is the direct cause of your drainage problem, begin a direct discussion with it’s owner and/or the local government to find a beneficial solution.
If poor drainage cannot be improved for whatever reason, consider planting species that can tolerate wet soil conditions.

When installing an extended underground downspout or sump pump drain, it is always a good idea to direct excess discharged water away from your foundation and into a water safe area several feet away (open lawn area, french drain, dry well, etc.).
A great way to finish off the open outlet point of a buried corrugated or PVC drain pipe (directed to an open lawn area – in particular) is with a pop-up drainage emitter cover. Unlike a standard round grate type drain cover which may allow soil and small debris to flow back into the buried pipe, a pop-up emitter is a clean looking alternative that remains closed until passing water pressure forces it open. They blend nicely into any lawn area (green color) and are the perfect outlet cover for any 3″ to 6″ diameter buried drain pipe installation.
The beauty of a buried landscape drain system is that it remains normally hidden from sight while automatically relocating excess stormwater that runs off a roof, large paved surface or any other impermeable area. Most residential drainage systems revolve around single or multiple buried drain lines that range in size from 3″ in diameter on up to 6″+ diameter (4″ drain pipe being most common – excess storm water dependent). Not only are there different pipe diameter sizes to consider, but also different materials as well. Depending on site conditions, amount of water to relocate, distance to extend across and location of pipe outlet (to daylight), one will need to choose between flexible plastic or solid PVC pipe. The most widely used types of drainage pipe are plastic corrugated, plastic corrugated and perforated, PVC solid, PVC solid and perforated.
One major problem with buried residential drainage systems that relocate water from an unscreened and unfiltered water source (downspouts connected to gutters with NO overhead leaf gutter guard protection in particular) is that debris can easily make it’s way into the buried pipe(s) and create clogs. As the buried pipe(s) become clogged, water flow at the outlet point can be reduced to a trickle and/or become stopped entirely. As you can imagine, without routine inspection and a thorough underground drain pipe cleaning (via vacuum, forced air or high pressured water jet), unnoticed clogs may lead to other serious problems around your property. Common problems like standing water, leaky basements, ice damming along roof edges, overly saturated plant material or even washout of nearby mulch or once compacted pavement base materials can be experienced when water flows into areas where it is not welcomed.
A solution for clogged buried drain pipes has recently become available and is manufactured by a company called NDS. They have created a simple catch basin filter that comes in two different sizes to fit their common 9″ and 12″ square shaped catch basins. Catch basins are commonly used under existing downspouts to funnel water underground to/through attached drain system. The NDS catch basin filters are removable and cleanable. They efficiently prevent dirt and debris from entering/clogging your underground drainage system.
