Sewage, storm water supplies, drainage and venting design principles are given in substances.
Sewage Facilities Design principles
1- contact with the sewerage of the relevant local authorities; rain water should be determined by the combined presence of sewage or sewage network. suitable for all sewers; places, showing the capacity and depth images should be obtained; law on sewage connections, should determine issues that need to be fulfilled and regulations.
2- Building in the rain and not suitable to be designed according to the combined piping sewage, rain and waste water installations should be fully installed independently and must be connected to the separate sewerage system.
3. at least one group of double sewage pump or ejector, if possible, building energy security must be connected to the electricity grid will form. To be critical of a fixed amount of drainage and safety of electrical installations (generator) a third sewage pump powered by diesel engines to be used in case of absence.
4- Drain should require no floor drain near the discharge rate allows the HVAC equipment and systems should be established.
5- sewage pipes, kitchens, food preparation, food service or ceilings should not be passed through the area where the storage of nutrients.
6 showing the need to clean the system in place should be placed sufficiently cleaning cover, covers all cleaning should be shown in the project. Flush pipes to get to the place with cleaning door open;or cleaning cover the vine in the piping from the ceiling, it would be appropriate to extend the cover plate on the floor upstairs.
7- place on the roof filters and ventilation shafts; be able to see the correct function of the roof parapets and chimneys 0.30 – 0.40 m should be placed away, vent pipe must be made at least 100 mm.
8 and passing through unheated areas must be insulated pipes that are otherwise exposed to frost.
Rain Facilities Design principles
1- All roofs, balconies, terraces and so on. place should be evacuated to the natural flow of city sewage or other waste water network system.
2- All site roads and sidewalks should be discharged into the natural flow into storm drains.
3- discharge ports on the roof sometimes placed by the architect. In this case the roof of the spout should be checked for their ability to function. Balcony, this is extremely important in places like canopy. It is an ideal place for four points. The connections are made to the columns and the main lines of the spout should be possible in the shortest length. Total column using more horizontal pipe in the ceiling of the top floor high-rise buildings should be reduced.
4- sewage pits intended for drainage of water should be considered sealed and ventilated garage.
5- If the garage waters of a nearby stream or sent to the lake to be found in the oil separator at the entry point.
6. Back in the reverse-flow valve should be put in place that may flow.
7- drain filters must be used for interior spaces and passageways, and they should be the type of flushing.
Waste Water Facilities & Air Conditioning System Design Principles
1 is located on the ground level and drainage require all plumbing appliances and equipment should be drained of natural flow to the sewage network or any other waste stream.
2 located below the ground level and drainage systems require all heaters, drain components and equipment must be drained into a sewage pit, sewage networks must be pressed with the aid of pumps here.
On more than 3-storey buildings, appliances must be connected to the links in the basement is not the natural flow system ejector system.
4- In buildings with more than twenty times each in the second and third floor plumbing appliances should be connected to the lower colon independently connected to the main column.
5. The upper and lower floors of the building has a different layout compared to other floors (usually the top and bottom indicating the need for many different column and joints from each other) need to think about the drainage system in two separate zones: the first providing independently be given to the sewage network in the street gathering of appliances upstairs system, while the other, the dumping of appliances on the lower floors, the installation of the vent and connect to the network through the corresponding zone of the roof system. This application is the column diameter and will not lead to excessive growth of the sub-column connection.
6- The advent of Appliance is deployed in a beautiful building, columns, which have a tendency to lose its column attributes curl up to a point. However, columns, crimped rate facilities in the building and should be reviewed in a flat format, it must only be installed in a minimum number of elbows for reasons of architecture; Taps those groups appliances should be connected to this column.
7. Generally, floor drains should be applied in the following locations:
a) Pump, compressor cooling the air compressor on, the vacuum pumps, boilers, water heaters and air-conditioning equipment in close proximity to the
b) Kitchens, automatic dishwasher, large refrigerators and other places nearby and needed a place to steam pot,
c) The toilet should be applied only in case of request of architects and business owners.
Garage Drainage and Venting Systems Design Principles
1 garage areas, to drain the water flowing from the car, to take his fire sprinkler water in place of the washing capacity to allow the hose must be equipped with drain elements.
2 Garage unloading filters; It must be connected to an oil separator before connecting to the sewage network or sewage pit.
3- the garage floor drains, precipitation removable outer space or in unheated garage must be equipped with buckets and mobile.
4- garage entrance and the entrance and the bottom of the exit ramp used for covering the full width of the ramp ditch grate type discharge channels are used. Grate the spout should be divided according to the preferences of the architects of cast iron or concrete channel, iron may be from the grid type.
5. Filters in the floor drain, the flow into the washing hose in the shape itself will take place and must be laid with a slope which is foreseen by the architect.
6 Garage drain filter should be selected in a minimum of 100 mm in diameter.
7- lowest level in two or more horizontal drain filter collects supplies for at least 125 mm 2 filter should be selected more than 150 mm for three and unloading.
