What is drainage and its types?
Many areas have some natural drainage; this means that excess water flows from the farmers' fields to swamps or to lakes and rivers. Natural drainage, however, is often inadequate and artificial or man-made drainage is required. There are two types of artificial drainage: surface drainage and subsurface drainage.

What is soil drainage?
Soil drainage is a natural process by which water moves across, through, and out of the soil as a result of the force of gravity.
What is the function of drainage?
One of the drainage system's functions is to collect surface water and/or ground water and direct it away, thereby keeping the ballast bed drained. The drainage system must also protect the substructure from erosion, from becoming sodden, and from losing its load-bearing capacity and stability.
What can proper drainage do for a building site?
A proper drainage system works to prevents excess water from damming up either in the ground surface or underground. Excess water, especially from rain, can easily build up without a proper drainage system.
What are types of subgrade drainage?
There are 4 main types of subsurface drainage systems:corrugated and PVC slotted subsurface pipes.mole drainage (including mole drains, mole drains over collector pipe systems and gravel mole drains)interceptor drains.ground water pumps.
What are the two main types of drainage systems?
There are two main types of drainage system options: surface drains and french drains. Surface drainage systems consist of a few ground-level areas drains that are connected to PVC piping. When it rains, water flows down the drains, into the piping, and is transferred away from the house.
What is an example of drainage?
For example, the total area drained by the Mississippi River constitutes its drainage basin, whereas that part of the Mississippi River drained by the Ohio River is the Ohio's drainage basin.
What is a swale system?
an open system consisting of a swale (often referred to as a ditch), sometimes with a culvert at its end to collect and channel water away, and a closed system consisting of gutters with catch basins. Combinations of the two are often used.
Can a garden hose be used to test water flow?
A garden hose can beused to test water flow, although its discharge cannotapproximate storm conditions. Where a building is situated on a hillside, it is more difficult to slope the groundaway from the building on all sides.
What is a swale in a storm drain?
Drainage Swales. Swales are wide, shallow ditches that provide a low-cost, low-maintenance approach to managing storm water and snowmelt. They are often used at the lot line between two homes or along the front or back lot line. Swales are shallow drainage ditches that can drain into storm sewers if permitted.
Why do we need a curtain drain?
A curtain drain can be used to intercept water flowing down a slope to protect your home or septic system from excessive runoff. Courtesy of NDS, In.
How to boost drywell capacity?

What is the main source of water in a house?
On most building sites, the main source of water around the house is runoff from the roof. Without proper management of roof water and snow melt, it often becomes the main source water in the basement. A well-designed system of gutters and downspouts that effectively collects roof water and discharges it away from the foundation is ...
How much water does a house shed?
A house with a 1,600 sq. ft. footprint, including roof overhangs, will shed about 1,000 gallons of water for every inch of rainfall. In a downpour, that 1,000 gallons gets deposited close to the foundation unless you have an effective system to collect and discharge that water elsewhere. The water is likely to saturate the soil around the foundation and exert hydrostatic pressure against the foundation wall. Under pressure, the water will find its way through any cracks in the concrete or block wall, as well as the joints between the basement wall, footing, and floor.
How does grass affect water flow?
The grasses and other plants slow the water flow, which reduces erosion and promotes infiltration back into the soil. Depending on the local topography and codes, swales may drain the water to wooded areas, streams or ponds, man-made “retention” ponds, or into storm sewers by way of subsurface piping.
How long is a splash block?
Manufactured splash blocks, which are typically about 2 ft. long with a molded channel,do a nice job of directing water away from the foundation. A couple of paver stones can work as well. Where the soil is likely to absorb the water an extended downspout to several feet from the foundation is often the best choice.

Serous Exudate. This type of fluid is normal from a wound in the early stages of healing, typically in the first 48 to 72 hours after the incision is made. 2 While serous fluid is normal in small amounts, experiencing large amounts of clear fluid leaving your incision warrants a call to your surgeon.
What is the term for severe bleeding from a wound?
Hemorrhage is the term for severe bleeding from a wound.

Is drainage a sign of infection?
That said, in some cases, drainage can be a sign of infection —something that's fairly easy to prevent by taking simple steps like proper handwashing. 1 Keeping an eye out for early signs of infection is also important, as the earlier infection is identified the faster it can be treated, which reduces healing time.
