DOMESTIC WATER SUPPLY

An ISO 9001:2000 Certified Organization

www.ramtech-corp.com

DEFINITION OF WATER SUPPLY

Water supply system means the water service pipe, the water distributing pipes, and the and the necessary connecting pipes, fittings, control valves and all appurtenances within the building or it may be outside the building, within the property boundary.

Water service pipe :-

"Water service pipe" means the pipe from the water main or other source of water supply to the water distributing system of the building served.

USAGE OF WATER

DOMESTIC :- The average daily domestic requirement of water like bathing, cooling, washing and toilet flushing for different type of building.

AIR CONDITIONING AND VENTILATION SYSTEM :- Large quantities of water are required for building equipped with evaporative cooled air conditioning/ refrigeration. In both cases the heat absorbed in the cooling equipment is exchanged with atmospheric air by spraying water on cooling tower.

SPECIAL REQUIREMENTS :- Water is required in buildings having laboratories, laundries, kitchens or other processes requiring water.

USAGE OF WATER

SWIMMING POOLS :- Large quantity water is required for ornamental pools, fountains, cascades for human comfort.

FIRE FIGHTING :-A small percentage of the gross storage of water is lost for fire fighting system provided in building for human safety.

GARDENING :- Building with gardens, internal landscape areas, plotted plants, and open courtyards require water for horticultural operations.

HOT WATER SYSTEM

INTRODUCTION :Hot water is needed for bathing and washing in domestic use. Higher temperature melt the sticky oil and grease from the human body, pot and pans, making the clean-up easy. Bathing with hot water opens the body pores, washing dirt and sweat easily and giving a sense of freshness. In other region at cold places hot water is necessary for daily life.

HOT WATER REQUIREMENT :Hot water is used in kitchens and bathrooms in residential areas. It is also required for laundries and industrial kitchens and in building like hotels, hospitals, schools, hostels, industrial canteens etc.

PREPARING A SECTIONAL

• PREPARE THE PLAN (SHOP DRAWING) AS PER ABOVE MENTION POINTS.

• DRAW THE CUTTING PLANE LINE ON TYPICAL TOILET AREA OR LOCATING COMPLICATED PIPE AREA.

• THE DRAUGHFTS MAN SHOULD THOUGHT THAT HE STANDING FACING TOWARDS THE ARROW MARK OF CUTTING PLANE LINE.

• BEHIND THE CUTTING PLANE LINE NEED NOT TO BE CONSIDER ON SECTIONAL VIEW.

• CONSIDER UP TO 1.5 METER FROM THE CUTTING PLANE LINE MARKING THE DIRECTION OF ARROW MARK.

GETTING A SECTIONAL VIEW

SECTIONAL VIEW OF ABOVE SLIDE

• MAKING THE AUTO CAD FILES IN TO TWO HORIZENTAL VIEW PORTS BY USING “VIEWPORTS COMMAND” AND SET PLAN ON UPPER VIEW PORTS AND DRAW THE SECTIONAL ELEVATION BELOW THE PLAN ON LOWER VIEW PORT. (SEE THE BELOW SNAP SHOT)

HOW THE SECTIONAL VIEW IS PREPARE ?

• DRAW ARCHITECTURAL ELEVATION FROM PLAN BY DRAWNING X-LINE FROM THE WALL WITH CONSIDERING THE FALSE CEILING HIEGHT, SLAB THICKNESS, FINISHED FLOOR LEVEL AND BEAMS REFERING THE SRUCTURAL AND ARCHITECTURAL FILE GIVEN BY CONSULTANT. (SEE THE BELOW SNAP SHOTS)

• DRAW ALL PIPES AT SECTIONAL VIEW IN DOUBLE LINE WHETHER IT APPEAR IN PLAN IN SINGLE LINE OR MAY BE IN DOUBLE LINE.

• SHOWING ALL PIPES WHETHER IT IS IN HIEGH LEVEL OR AT LOW LEVEL WITH ITS FITTINGS, CONSIDERING THE SHOP DRAWING AND MENTION THE BOTTOM OF PIPE AND PIPE DIAMETER AS FOLLOWS BY STANDARD RECOMMENDED BY CONSULTANT.

SINGLE LINE PLAN OUTPUT

PIPES IN DOUBLE LINE AT SECTION

• PLACING ALL THE ELEVATIONAL FIXTURES APPROVED BY CONSULTANT WITHIN THE SECTIONAL VIEW.

• MENTION THE TYPE OF PIPE AND BOTTOM OF EVERY PIPE FROM FINISHED FLOOR LEVEL

• DIMENTION THE HOT WATER AND COLD WATER PIPES SUPPLY TO THE FIXTURES AS PER STANDARDS GIVEN BY CONSULTANT

BOTTOM OF PIPE

THE DISTANCE FROM THE FINISHED FLOOR LEVEL(FFL) TO THE BOTTOM OF INSULATED PIPE IS BOP. THE WATER PIPES HANGS BETWEEN SLAB AND FALSE CEILING LEVEL WITH SUPPORTERS. IF IS INTERFERENCE & FOULING WITH DUCT OR OTHER EQUIPMENT, IN THAT CASE WE USE TO BEND THE PIPE AS UP & DOWN, THEN FOLLOWS THE ROUTING.

FOR CALCULATING THE BOP VALUE

FFL OF CURRENT FLOOR______________(FROM ARCH. LAYOUT) SSL & SLAB THICKNESS OF THE ABOVE FLOOR__________(FROM STRUCTURAL LAYOUT) FALSE CEILING LEVEL MUST BE GREATER THAN 2400MM FROM FFL.

• CONSIDERING THE FALSE CEILING LEVEL WATER PIPES RUNNING 100MM APPARTS.

• ALWAYS PREPARED HOT WATER RUNNING APPROXIMATELY 100MM DISTANCE ABOVE FROM THE COLD WATER PIPE LINES.

PROCEDURE FOR BOTTOM OF PIPE An ISO 9001:2000 Certified Organization

• BOTTOM OF PIPE MUST BE GIVEN FROM THE STARTING POINT THAT IS FROM RISER TO THE TILL END OF THE WATER SUPPLY TO FIXTURES AND SHOULD BE GIVEN TO ALL INDIVIDUAL PIPE LINES.

FOR EXAMPLE : LET Ø65 PIPE IS RUNNING TO THE APPARTMENT FROM RISER CONSIDERING THE BOTTOM OF LEVEL AT STARTING POINT FOR HOT WATER 2850 MM AND FOR COLD WATER 2750 MM FROM FINISHED FLOOR LEVEL.

• AFTER SOME DISTANCE IT REDUCES TO Ø42 MM

• CALCULATING THE BOP 65-42=23MM/2=11.5MM ROUNDING IT TO 12 MM APPX.

• MEANS Ø42 MM HOT WATER PIPES BOP 2850-12= 2838 MM FROM FINISHED FLOOR LEVEL.

• SIMILARLY FOR Ø12 MM COLD WATER 2750-12= 27385MM FROM FINISHED FLOOR LEVEL.

PROCEDURE FOR BOTTOM OF PIPE

PREPARING A ISOMETRIC DRAWING

• SET THE DRAWING AREA INTO TWO HORIZONTAL VIEWPORTS BY USING “VIEWPORTS” COMMAND.

• ADJUST THE UPPER VIEWPORT IN SOUTH\WEST ISOMETRIC VIEW TO THE PLAN.

• ADJUST THE LOWER VIEWPORTS IN THE ISOPLANE ANGLE TO WORK IN 90 DEGREE AND 30 DEGREE ANGLE, BY USING “SNAP” COMMAND.

• Specify snap spacing or [ON/OFF/Aspect/Rotate/Style/Type] <0.5000>: S

• snap grid style [Standard/Isometric] <S>: I• Specify vertical spacing <0.5000>: Enter• THIS COMMAND PROMPT SET THE CROSSHAIR INTO ISOPLANE.• “F5” BUTTON IS USE TO CHANGE THE CROSSHAIR INTO

VARIOUS X AND Y DIRECTION.• REFERING THE ROUTING OF HOT WATER & COLD WATER AS

PER SHOWN IN PLAN STARTING FROM ELECTRICAL WATER HEATER TO TILL END OF THE WATER SUPPLY.

• GIVE ALL THE PIPES BOTTOM OF PIPE AND SIZES CONSIDERING A FINISH FLOOR LEVEL LINE.
