In this article we will dwell on the problem of drainage of raw sites: the device of what systems is necessary, how to include elements of drainage system in the landscape design, is it possible to create a landscape design on raw and even wetlands without drainage at all.
Before starting the landscaping work, it is necessary to determine the feasibility of the site drainage system. The purpose of the drainage system is to collect and divert excess water from the site. Installation of surface drainage systems is necessary almost everywhere, it is due to the peculiarities of weather conditions in most regions of USA, such as high precipitation throughout the year and average summer period.
Underground landscape drainage pipes do not affect the location of landscape elements, but there is one point that needs to be taken into account. When constructing an underground drainage system, rotary, inspection and absorption wells are installed. Their covers need to be decoded, while allowing free access to them.
On a damp site it is possible to arrange a natural pond by arranging a drainage system so that all water is discharged into it. As a rule, such areas are located on the underlying clay layer. It is in this layer that the excavation of the pit is necessary, making it so to go beyond it. Otherwise, the water from the pit will go to the next aquifer. Such a pond can be a real decoration of the site, if you take care to strengthen its banks. If there are several wet spots on the site, you can arrange a system of ponds connected to each other by bridges.
