Surface drainage, point drainage, internal drainage and underground drainage:

Surface drainage systems are intended for tap rain, thawed, and also waste and process waters. The linear drainage system is widely applied in a construction of roads, sidewalks, arrangement of personal plots, the equipment of industrial shops and the open areas.

Linear drainage solves a problem of formation of pools and water streams after storm rains or snow thawing that provides safety of a road covering. Water drainage directly from buildings protects the base from destruction, and cellars and ground floors - from flooding.

Surface drainage represents a set of the profound channels closed by demountable gratings, and trash boxes. Trash boxes are intended for deduction brought by sand and dirt water. Demountable gratings do not allow to get to drainage systemlarge dust. Besides, gratings create safe conditions for movement of people and transport.

For outflow of water, system of surface drainage incorporates to the storm sewer.

At building, the point drainage arranged with the help of drain box is necessarily applied. Point drainage system is applied to local gathering of water under drainpipes, in pits and so on. Besides, point drainage system can supplement a linear drain in those places where fast removal of surpluses of water is required: on platforms before an input in the house, parkings, on entrances and paths. From above drain box is necessarily closed by mesh grating, made of steel, cast-iron or plastic.

The given drainage system takes away arriving water in the storm water drain.

In addition drain boxes, which help point drainage to be arranged, can be equipped by the siphons-partitions intended for deduction of an unpleasant smell from the water drain, and also baskets for gathering of getting dust.

Correctly designed point drainage protects the base of buildings from destruction, and also prevents water hit in socles and cellars.

Internal drainage made of stainless steel is used at the industrial enterprises on which the special sanitary-and-hygienic mode should be observed. For example, such system of a drainage system is necessary in food or a pharmaceutical industry.

All accessories which are included by an internal drainage system, are characterised by the raised firmness to oxidation, hygienic, simplicity of sanitary processing and long service life.

The internal drainage includes channels, traps and gratings. Channels are used for gathering of sewage and their tap to a trap. From above channelsare closed by the gratings providing safety of the personnel and protecting a drainage system from hit of extraneous subjects. Traps deduce sewage directly in the water drain. All traps are equipped with catchers of mechanical impurity, hydroshutters and drain gratings. All elements from which the internal drainage is mounted, are made of high-quality stainless steel.

Internal systems of drainage can be used not only at building of industrial buildings, but also at their reconstruction and modernisation.

The underground drainage represents system of the channels laid underground which serve for tap of ground waters from a site. Underground drainage is necessary when level of ground waters is high enough: for example, near to reservoirs or in marshland. The deep drainage is also necessary when in the house there is an underground garage or a ground floor.

Without underground system of a drainage system it is possible to manage under condition of sandy, well draied ground, and the ground waters lying in one and a half and more metres from a surface.

Deep and superficial drainage are intended for the decision of various problems. The underground drainage is necessary for fall of level of ground waters, superficial drainage - for tap of surpluses of an atmospheric precipitation. Two these systems do not exclude each other and can be mounted in common. At designing of joint system of a drainage system it is necessary to provide additional loading on a collector. Competently designed uniform system of a deep and superficial drainage allows to solve a water removal problem effectively.
