Construction Of Water Supply Systems
Modern heating systems, water supply and sanitation is an important and integral part of any building and, to a large extent, provide comfort and facility operation costs for its maintenance. At the same time, is quite complex and specialized work. When designing water and wastewater systems must necessarily be taken into the numerous regulations, including: government standards, specifications, building codes. Before beginning design work on water supply at home (private house water supply) should be informed of the purpose and design of buildings, location of its on the terrain, weather and operating conditions of premises, existing sources of heating and water supply. Modern water systems are an important and integral part of any building and, in a large extent, provide comfort and facility operation costs for its maintenance. When designing water and wastewater systems must necessarily be taken into the numerous regulatory documents, including national standards, specifications, building codes. Before beginning design work on water supply at home (private house water supply) is necessary to have information about the appointment and construction of buildings, location of its terrain, climate and mode of operation of the premises, available sources of heating and plumbing.
For the purposes of water use natural water sources: superficial surface water (rivers, reservoirs, lakes, sea) and groundwater (groundwater and artesian waters and springs). The general scheme of water may vary depending on specific conditions. For example, water source does not require cleaning, fall cleaning of the scheme and related structures. When placing the source at higher elevations than the water-fed facility, the water can be supplied by gravity, and therefore there is no the need for the device pumping stations. Location of water towers and reservoirs depends on the terrain. Some systems use multiple sources of water, which leads to an increase in basic facilities.
With a large difference in elevations at the site sometimes the so-called zonal arrange water supply, ie, separate networks for the city, located at different elevations, with separate pump stations. Sometimes erect booster pumping station, taking water from the main network of the city and return them to the elevated areas. Pumping stations are equipped with modern water supply systems are usually centrifugal pump with electric drive, as well as regulatory, safety and test equipment. Many pumping stations have a remote control and fully automated. Recently proved to be the best side system with variable-frequency drive pumps. Sewage treatment plants is treated natural water to give it qualities that meet the requirements of consumers. Purified Water is supplied to the facility conduits and bred on the territory water network. Go to the street network attached houses a branch, through which water is introduced into the building. Inside the building is arranged an internal network water, the feed water to the point of parsing through the various water-devices. For industrial enterprises (under certain conditions) using the so-called circulating water system, as well as systems with consistent use of water. Current systems are designed to prevent irrational use of natural water and its pollution. In such systems the water after proper treatment (cooling or lightening) again served to consumers. To cool the water circulating systems use cooling towers, pools bryzgalnye, cooling ponds.
