Plumbing Works In High Rise Building

A Vision To Clear Solutions.

Introduction

(a)  The pipes, fixtures and other apparatus inside a building for bringing in the water supply and removing the liquid and water borne wastes

 (b) The installation of the foregoing pipes, fixtures and other apparatus.

Pipe – pipes shall have adequate strength to meet the loading requirements

 Plumbing System

The plumbing system shall include the water supply and distribution pipes; plumbing fittings and traps; soil, waste, vent pipes and anti- siphonage pipes; building drains and building sewers including their respective connections, devices and appurtenances within the property lines of the premises, and water-treating or water-using equipment.

1.      Methods

2.      Drinking water supply

a.       Residential- number of fitment is less

b.      Commercial – number of fitment is more

c.       Industrial – number of fitment is more

(Like water cooler, machine drains and washes room)

1.      Drainage and sanitation supply

2.      Gas supply

Points to be consider before laying

·         Material inspection and test result as per IS codes

·         Excavations –(supports or shoring to be provided in deep excavation, steel sheet piles to be use in slips and falls)

·         Backfill-(the material satisfy stone size 150mm/liquid limit is less than 30%/plasticity index no more than 10)/bedding/ geo textile membrane to be provided around the stone filling area

·         Dewatering

·         Free from water, storm, oil, etc.,

·         No blasting

·         Pipe tolerance (the angle deviation of bends shall be within +-1 degree of the designated for pipes including 600mm dia and + – 0.5 mm for large dia pipe. Fitting shall be within + -10mm of the designated length or the manufacturer catalogue values)

·         No crack shall be present in the inside of the pipe

·         Scratches shall be no more than 0.3mm

·         Impact and external pressure resistance

·         Longitudinal tensilestrength to be made accordance with IS code

·         No impact and other end damages

·         Overall thickness, pvc packing thickness, tensile strength, elongation, tear resistance,  adhesion to steel, adhesion to self, impact resistance, dielectric strength and insulation resistance should satisfy the IS code requirements.,

·         Defective parts can be replaced without difficulty

·         Check the suitability of the pipe

·         Follow the recommendations of manufacturers when joining pipes of different materials

·         If lab- pipe suitable for conveying all solutions

·         No leakage of contaminated water

·         Materials, joints, supports and fixing shall be durable

·         Sealant provide all joints carefully

·         Work /all appliances/ materials & workmanship should be carefully examined for defects and faults in installation.

·         Good inspection and testing

·         Setting out and alignment

·         Joints- push fit /mechanical/flanged/grp/anchorage

·         Provide proper support/thrust blocks

·         No bents

·         No airs at bended corners

1.      Drinking water supply

In general, a daily per capita water consumption of at least 200 liters may be used for most of the e large town and cities in India as design figure to meet domestic and flushing needs, However, for lower income group ( LIG ) and economically weaker section of the society the value of water supply may he reduced to135 liters per capita per day.

1.      Types

2.      Cold water supply

3.      Direct & indirect system of cold water supply

4.      Valves and taps

5.      Joints on water pipes

6.      Pipe joining materials

7.      Water mains

8.      Cold water storage cisterns

9.      Pipe sizing by formula

10.  Pipe sizes and resistances

11.  Hot water supply

12.  Direct & Indirect system of hot water supply

13.  Hot water storage cylinder & capacity

14.  Medium and high-rise building supply system

15.  Electric and gas water heaters

16.  Solar heating of water

17.  Pipe sizing

1.      sewage / drainage plumbing system

2.       Disposal methods

·         Combined methods

·         separate methods

·         Partially separate methods

                  System

·         Two pipe system – ground water and waste water separated and mostly accepted system

·         One pipe system- one main pipe collects both waste and ground water      with ventilation

·         Single stack system-same as one pipe but no ventilation

·         Single stack partially ventilated

                  Sewer connection

                  Drainage ventilation

                  Drain pipe laying

                  Means of access

                  Bedding of drains

                  Drains under or near buildings

                  Pipe cleaning and inspection

                  Gas supply
