A Drain In The Ocean, What Does Drainage Mean?

When you're facing the terrifying force that is water, you'll probably want to do everything you can to keep your assets safe from damage and destruction. As a result, the word 'drainage' might come to mind, but it's important that you're able to answer one important question: what exactly is drainage?

A Drip In The Bucket
On a broad level, the act of drainage is to remove water from an area, whether that's above or below the surface of a structure or area. This typically becomes an important part of many civil projects, where the extra weight and erosion provided by large amounts of water collecting on fields or roofs can quickly lead to substantial bills.

This wastewater is know as 'effluent', and it can collect in a variety of places in a range of manners. If it is in the sub-surface, it is likely to be subsoil water, which the earth has collected to attempt to lower the water table. Anything that is above the surface is, logically, surface water, and you can find this pooling in your roof, between your paver bricks, or along any other artificial structure.

The wastewater your building generates is still called effluent, but it doesn't fall under these two categories. Instead, the content of the effluent determines if it is foul water or soil water: sinks and basins that don't contain human waste generator foul water, while toilets, urinals, and showers generate soil water.

A Table Made Of Dirt
When subsoil damage occurs, your building is likely to be standing on shaky ground, quite literally. The stability of the foundations of your building can be put at risk, or the land may not be capable of it's full horticultural potential. As a consequence, draining sites before work begins can be a common requirement, and you'll also need to think about installing permanent solutions to make sure your building will be protected from the rising water table.

Generally speaking, you tend to achieve this using porous pipes that pull in subsoil water from the dirt around them, but this can only be done to a depth of one and a half meters. If you need to lower the water table any lower than that for whatever reason, which are typically agricultural in nature, then you're going to need to discuss alternative methods with your civil contractors.
