SANITARY INSTALLATIONS

TECHNICAL STATEMENT

1.Generality

This documentation includes technical solutions for water and sewerage facilities related to a D + P + M building located in city street ... .

Documentation was approached at D.T.A.C

The project formed the basis of preparation:

Architecture and structure-plans

Standard 1478/1990 water-supply to industrial and civil construction and design requirements for calculating basic

Norm-I9-94 Standard for the design and execution of sanitary installations.

-The general rules for fire protection

Standard P118-technical norms for fire safety of buildings

NP-Standard 086-05 Standard for the design, implementation and operation of fire fighting facilities.

Sewerage and Drainage inner-STAS 1795 -90. Fundamental requirements calculation and design.

-Equipment suppliers of technical books

IPCT-GP 043-99 Guide for the design, implementation and operation of water supply systems and sewerage systems, using PVC pipes, polyethylene (PE) and polypropylene (PP).

Law-Law 10-2005 on the quality of construction

Building height is the basement, ground floor, attic, bound for the house and is composed as follows:

-Basement: two outside entrances, living room, bedroom, bathroom, bathroom, laundry, kitchen.

-Floor: two outside and two entrances to the attic entrances, hallways and living room, bedroom, bathroom with shower, kitchen.

-Attic, three bedrooms, two bathrooms, toilet cabin.

Consumption of cold water and hot water and domestic sewage discharge is appropriate a total of four persons:

Cold-water daily consumption:                                                              1.12 cm / day

Cold water-use zone within                                                                     0.15 m / h

-Maximum daily wastewater flow                                                           1.1mc/zi

Maximum hourly flow wastewater-                                                        0.2 m / h

Flow calculation determined by the number of sanitary

Computation-flow cold water plant building 0.79 l / s

Air-flow calculation building hot water                                                    0.61 l / s

-Flow calculation for the entire building sewerage                                    2.98 l / s

Proposed Solutions

Providing drinking water supply and wastewater sanitation is by connecting to existing networks and the installation inside the newly designed internal

It keeps the entrance and exit routes from the building to replace the pipes, observing the existing crossings through foundations and basement walls.

Indoor plumbing

Cold water needs of the building for domestic and sanitary purposes is 1.12 cm / day, for flow calculation of 0.69 l / s is provided by the current connections are ¾ ".

Given that the flow and pressure fluctuations street network does not allow a proper functioning of the interior installation, provide for a pumping plant with its own container member 50 liters to 300 liters buffer tank opened and the pump has a flow of 0.7 liters / s and pressure control 15 ÷ 22mCA.

The installation is mounted in the laundry demisol.Necesarul 0.44mc/zi hot water is calculated at a rate of installation of 0.26 l / s ÷ 0.35 l / s, are provided by wall mounted boilers equipped with a basement and ground floor plate heat exchanger or reservoir, with a flow of 16 l / min. hot water to an average difference of 25 ° C.

Disposal of wastewater is the road network via the existing home that will limit the property to recover the maintenance allowance actuale.Imobilul record comes with the following equipment and sanitary:

- Basement: kitchen with washer and dishwasher record for laundry with washer and washing machine, toilet and bathroom with tub, sink and toilet installation, boiler wall.

- Ground floor: kitchen with a stainless steel sink with two tanks, dishwasher murala.Grup heating bathroom with shower equipped with sink, toilet facility on board tank, shower.

- Attic: 2 bedrooms 2 bathrooms equipped with bathtubs, three restrooms, two restroom facilities with flush tank, washing machine.                                     

Hot and cold water installations will be made of copper pipe for distribution routes and columns and reticular polyethylene pipe, multilayer REHAU PE xA (RAUHIS) in the sanitary pipes connecting the columns.

Sanitary connections to the columns is as follows: through parts REHAU joints with sliding sleeve that allows the location of pipelines REHAU PE xA in the same way as metal (only this type of joint allows positioning directly under the concrete floor or plaster.

All special parts ie tees, reducers, elbows, brass nipple are zincata. Sanitary valves will isolate type sublavoar corner.

Emptying the installation is complete by handling the drain valves located in the basement with portfurtun the distribution pipes and connected to channel traversing the basement.

Indoor  installation is metered consumption.

Domestic wastewater is collected via column-mounted drain pipes dustbin grouped with hot water, cold water, heating, and horizontal collectors leading home waters outside the existing building.

Drainage facilities were set polyethylene type VALSIR - fireproof.

Sanitary sewer connection to be made by technical curve fitting and floor drains with multiple connections and connecting vertical drains for washing machines and dishwashers.                                                                                                                    

For the protection of sanitary fittings were provided strainer on the supply of drinking water and building the boiler feed line, a Y and a magnetic filter.
