Flooding of a country house and cottage can be a real problem for its owner. Only the drainage system can solve it once and for all. Especially if the territory of the house is located in a lowland and it is not possible to make artificial drainage of water.According to its type, the drainage system is divided into two types:- Open.- It's closed.Each of them has its own differences and areas of use.Open drainage, this type of drainage is considered the simplest and most popular. It has a network of channels that are located at different heights and slopes. Such drainage is laid in places of expected flooding. As a result, the water is quickly and efficiently discharged into the sewer. The open drainage system successfully copes with rainwater and spring floods. If there is groundwater, it lowers its level. This system has proven itself well in the absence of trees and if there are large height differences. But open drainage is not without its drawbacks. In some cases, its arrangement is impossible, and the main reason for this is the changing terrain on the construction site.Closed drainingthe creation of a closed drainage is a more laborious process. It requires the manufacture of hidden channels, drainage basins, sewage treatment wells, and the like. One of the most common types of closed drainage is backfill drainage. This method is simple and cheap. Its system is equipped with open drainage channels. In certain proportions, they are filled with crushed stone and gravel. A drain is laid on top of the ditch.Another closed drainage technology is the use of wells and drainage pipe systems. Drainage channels are built at a depth of one meter. The pipes are laid in a half-meter layer of crushed stone, sand and drainage. All the water is channeled into the wells. The system of such channels is called drainage. The drains themselves can take on different forms of bonding. This will be influenced by the drainage tasks and the terrain of the site. For example, if the area of the site is large, then a chain is used. In this case, the central drain receives water from the adjacent drains, diverting it to the receiving well.Wells are necessary if drainage pipes are used and when a large volume of water is expected to be collected. Due to the presence of such wells, it becomes possible to clean the drains and flush the entire system from various kinds of contamination. Such a system will be effective depending on the drainage angle, depth and distance between drains. A sufficient slope minimizes the chance of clogging the entire system and other resulting consequences.
