Residential drainage includes landscaping, culverts, irrigation systems, and foundations. Developers consider natural slope, absorption rates, and groundwater tables. Septic tanks are soil-dependent and may require a drainage field. Gutter systems and underground pipes direct rainwater away from the property and benefit the entire city by preventing flood areas and recycling water.
There are many types of residential drainage available to consumers, and most of them come in the form of landscaping. While the pipes that carry excess water and wastewater away from the home are definitely important, the most important factor is the soil’s ability to absorb these nutrients and flush out standing water around the structure. This task is carried out through culverts, irrigation systems and the foundation on which the residence stands. Gutters and roof drains also play an important role in ensuring that rainfall is distributed to the parts of the property with the greatest runoff.
When a developer first inspects a site and thinks about residential drainage, they search the property to determine the natural slope and groundwater tables. The house is normally built at the highest point to ensure that water always drains from the structure, and when the ground is particularly flat a building platform can be created out of rock and sand. The soil absorption rate will also be considered and, in areas where standing water is a problem, irrigation channels could be created to speed up the evaporation process. Other areas have very good absorption rates and this phase of residential drainage is completely ignored.
A septic tank is another form of residential drainage that is highly soil dependent. The residence’s pipes carry the sewage from the toilets into a large holding tank and from there the water naturally seeps into the soil to fertilize the soil. Areas with poor absorption rates may need to install what is called a drainage field that allows waste to flow great distances from the reservoir. However, this formula is not left to guesswork and engineers often obtain a soil sample to determine the length and thickness of the underground drainage. Some locations may also offer a city sewer system for residential drainage.
In particularly problematic locations, an underground pipe network may be installed to allow water to drain off the property. From the moment rain falls on a roof line, it is directed away from the property through gutter systems. It would eventually end up inside a culvert that allows rain to flow freely through many properties and usually end up inside a local river or lake. This type of residential drainage benefits the entire city by preventing flood areas and recycling water at the same time. Eventually, that moisture ends up in a purification plant so it can be converted back into potable water.
