Learn the Best Ways to Deal with Storm Water

Sep 30,  · To build a French drain, choose a spot with a slight downhill slope, then dig a trench that is about 6 inches wide and 18 to 24 inches deep. Line the trench with water-permeable landscape fabric, leaving at least 10 inches of excess fabric on either side of the trench. Jun 25,  · Best Pipe for a French Drain. Pipes specified to be used on French drains pipes are normally 6-inch diameter perforated PVC SDR If the job or area to be worked is small, you might want to try a four-inch pipe but remember it will all come down to the amount of water being handled.

These landscape drainage solutions prevent puddling and flooding and look good too. You can turn landscaping for water drainage solutions into features that enhance your yard—and protect natural waterways. Ditches can be landscaped as swales that look like creek beds or small meadows.

Gutter water can flow into rain gardens that provide a habitat for butterflies and birds. And driveways, patios, and walkways can be constructed of pervious paving that never puddles because water seeps through.

Since these yard drainage ideas allow storm water to sink into the soil gradually, they help reduce flooding. Plus, they allow pollution, including oily residue from cars, to filter out naturally, so it doesn't wind up in lakes or streams.

Swales are depressions that follow the contour around the base of a slope natural or createdchanneling storm water from one place to another.

They filter runoff along the way by allowing it to sink into the soil. Fast-draining soil is also key. Along the sides, she uses evergreen ferns, sedges, winterberry, grasses, and Siberian and Louisiana irises that thrive in moist conditions. Rugged prairie plants or other natives that are at home in fast-draining soil are another option. You can build a small swale yourself, but for a long, wide one you'll want to hire a pro with earth-moving equipment.

Consult a landscape contractor book on how to build a house a civil engineer if you live drainzge a bluff, have a septic tank nearby, or are on a slope that drops more than 1 foot over a horizontal distance of 20 feet.

A swale should carry water to a drainagge where it can be released safely, such as a garden bed with good drainage or a buried dry well; allowing it to be absorbed on-site, rather than flow into a storm drain, is important for protecting natural waterways. If water sinks in half that fast, amend it with 40 percent compost.

Top the gravel with at least 8 inches of a compost-rich soil mix. Shallow catch basins planted as flower beds, rain gardens allow water to pool during a downpour, then slowly percolate into the soil. Where a swale is mostly a travel route for water, a rain garden is a destination. A fast-draining soil mix encourages water to sink in and promotes lush plant growth. Runoff may flow into a rain garden from a swale or pipe, or may simply run in from a sloping yard.

Rain gardens are appropriate drainage spots for steeper slopes than swales can handle, but where the surface drops more than 3 feet over a foot horizontal distance, you should get professional design help. Although a low spot in the yard might seem an ideal placement, if it hkw soggy, it's already saturated.

Instead, pick an area that dries out quickly. Designing a rain garden to handle all of the runoff from a roof or driveway entails careful calculations. But you can also learn by experimenting: Build one, watch what happens after a storm, and then enlarge it as needed. Locate a rain garden at least 10 feet how to cut and serve mango your house and at least four times that far from a septic system or steep slope.

Though you can excavate a small say, 5-byfoot rain garden yourself, a landscaper with an earth-moving machine will get it done faster.

Mix in compost and drainahe, as needed, using the same proportions as for a swale. Plant the center of the area with species that tolerate wet conditions, such as native sedges and lady fern. Around these, put plants suited to occasional standing water, like redtwig dogwood.

A: Water flows in from slope, paved area, or pipe B: Wide, shallow basin with flat, level bottom and gently sloped sides C: 12 to 24 inches of fast-draining D: 2 inches of mulch E: 6 inches of ponding depth F: Berm or stones to stem or slow down overflow G: Perennial plants. This keeps the top surface dry, eliminates runoff, and lets water in the gravel layers gradually sink into the soil.

There are three basic types: concrete pavers with voids in between to be filled with gravel or sand with or without grass ; porous concrete or asphalt made with little or no sand so there are built-in air pockets; and plastic grids that keep a djtch layer of gravel or sand with or without grass from ditcch, so water drains through.

Pervious paving is suitable for gentle inclines that slope no more than 1 foot over a horizontal distance of 20 feet. Though a small-scale paver or grid-system project like a pervious walkway or patio might be a DIY job, you'll likely need professional design help for a driveway, where soil is heavy with clay or freezes deeply, or if the job is tied into how to play a hermonica building permit.

Plastic-grid systems are the most DIY-friendly, requiring a gravel base layer of only 2 to 6 inches, compared with about a foot for the other systems. The base can be tamped with a plate compactor, which you can rent; the frainage is simply rolled out and pinned down along the edges; and spaces are filled with decorative gravel or sand, plus grass seed, if you like.

As more communities limit the amount of impervious surfaces rooftops, conventional hardscape allowed on residential lots, interest in pervious paving has skyrocketed. Shown: Some concrete pavers have larger spaces to hold sand and turf grass, which absorb some storm water near the surface.

A French drain or a drain tile is built by filling a trench with gravel and a perforated pipe is used at the bottom to divert underground water. A geotextile fabric wraps the pipe and gravel acting as a sieve where fine sediments will not pass to the area where the gravel is located. A properly designed french drain reduces the pressure exerted upon retaining walls and subgrade walls that with time can induce moisture inside basements and crawl spaces. A French drain system is an indispensable component of any subgrade waterproofing project.

A French drain will move water and moisture away from the property, reducing water ponding and flooding in the back, patio or front yard. This is a common alternative used in the following applications:. The drainage system should not be more than 12 inches wide, between 6 and 8 inches will be ideal, because it will probably last longer and water will be collected and transported better with fewer obstructions.

The pipe installed in the trench must also be installed with the holes on the bottom. The French drain system should be installed deep enough, so water will eventually run into the pipe, instead of moving near or into the structure.

The recommended slope of the perforated pipe for a french drain system is a one-inch drop per ten feet horizontal run. When a French drain is used to protect a living space, the invert of the bottom shall be placed at least 2 inches below the level of the finish floor. However, it is recommended to use a professional consultant that can determine the correct elevation of the drainage system.

If the job or area to be worked is small, you might want to try a four-inch pipe but remember it will all come down to the amount of water being handled. Some experts recommend using smooth wall pipes, while others tend to use corrugated pipes. A perforated pipe is manufactured with two rows of round holes, normally installed facing the bottom of the trench as part of the french drain system. As a contractor, you might want to add a fabric filter to help reduce the clogging of the pipes.

Also, you might want to make sure that the right slope and the piping size is adequate to handle the water flow. The upper 12 inches above the pipe shall be filled with native soil, to avoid having crushed stone over the perforated pipe that could damage the pipe.

It is important to place the gravel around the pipe because they will filter any sediment that the geotextile is not able to remove. An important piece of a french drain is the geotextile that covers the pipe.

All crushed stone shall be protected and wrapped by a geotextile filter, a long-lasting manufactured material that will protect the pipe. The introduction of a drainage fabric around the aggregate can prevent in-situ soils from being washed into and clogging the drain. These geotextile filter fabrics will prevent soil fines from entering the drainage system, extending drain life and increasing performance.

There are prefabricated drainage systems made of two parts: a geotextile fabric and a molded plastic core. Geotextile fabrics are attached to the core, providing excellent drainage while preventing the backfill from entering the core channel.

These prefab drainage systems can reduce installation costs because they can be installed faster than traditional drain tile. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile.
