  25. 25. INTRODUCTIONIt is the arrangement provided in a house or buildingfor collecting or conveying waste water through drainpipes, by gravity, to join either a public sewer or adomestic septic tank is termed as house drainage orbuilding drainage.
  26. 26. SANITARY SYSTEM
  27. 27. AIMS OF HOUSE DRAINAGETo maintain healthy conditions in the buildingTo dispose off waste water as early and quickly as possibleTo avoid the entry of foul gases from the sewer or the septic tankTo facilitate quick removal of foul matterTo collect and remove waste matters systematically

  29. 29. PIPES Material Application Jointing Cast iron 50 mm and above vent and discharge Lead caulking with molten or fibrous stacks lead; cold compound caulking Galvanised steel Waste pipe Screwed Copper Waste pipes and traps Compression, capillary, silver solder, bronze weld or push-fit rings seal Lead Waste pipes and discharge stacks Soldered or lead welded ABS Up to 50 mm waste and vent pipes Solvent cement and push-fit ring seal (acrylonitrilebutadiene styrene) High-density Up to 50 mm waste and ventilating Push-fit ring seal and compression polyethylene pipes and traps fittings Polypropylene Up to 50 mm waste and ventilating Push-fit ring seal and compression pipes and traps couplings Modified PVC Up to 50 mm waste and vent pipes Solvent cement and push-fit ring seal Unplasticized Over 50 mm soil and vent stacks; Solvent cement and push-fit ring seal PVC vent pipes under 50 mm Pitch fibre Over 50 mm discharge and vent Driven taper or polypropylene fitting stacks with a push-fit ring seal
  30. 30. PIPES Soil pipe: A soil pipe is a pipe Through which human excreta flows. Water Pipe: it is a pipe which carries only the liquid waste. It does not carry human excreta. Vent pipe; it is a pipe which is provided for the purpose of the ventilation of the system. A vent is open at top and bottom, to facilitate exit of foul gases. It is carried at least one meter higher than the roof level. Rain water pipe: it is a pipe which carries only the rain water. Anti-siphonage pipe: it is pipe which is installed in the house drainage to preserve the water seal of traps.
  31. 31. SIZES OF PIPES Soil pipe: 100mm Waste pipe: horizontal: 30-50mm Waste pipe: vertical : 75mm Rainwater pipe : 75mm Vent pipe: 50mm Anti siphoange pipe: Connecting soil pipe: 50mm Connecting waste pipe: 40mm
  32. 32. TRAPSA trap is depressed or bent fitting that, whenprovided in a drainage system, alwaysremains full of water, thus maintaining waterseal. It prevents the passage of foul air orgas through it, though it allows the sewage orwaste water to flow through it. The depth ofwater seal is the vertical distance betweenthe crown and dip of a trap. The depth ofwater seal represents its strength oreffectiveness. Greater the depth of water sealmore effective is the trap. The depth of waterseal varies from 25mm to 75mm.

  44. 44. PLUMBINGSYSTEMSSINGLE STACK SYSTEMFULLY VENTILATED STACK SYSTEMONE PIPE SYSTEMDUAL PIPE SYSTEM MODIFIED SINGLE PIPE SYSTEM
  45. 45. ONE PIPE SYSTEMIn the system all soiland waste waterdischarge into onecommon pipe and allbranch ventilatingpipes into one mainventilating pipe. Thissystem largelyreplaces the two pipesystem and lent itselfvery well to use in multistorey developments. Itis far more economicalthan the two pipesystem.
  46. 46. TWO PIPE SYSTEM The waste stack received the discharge ablutionary fitments and conveyed this to the ground level where it was delivered above the water seal in a trapped gully connected to the drainage system. the soil stack receives the discharge from soil appliances and delivered it direct to the underground drainage system. The waste and soil water did not combine until they reached the below ground drainage system.
  47. 47. THE FULLY VENTILATEDONE-PIPE SYSTEMA large number of sanitaryappliances in ranges.Each trap with an anti-siphon or vent pipeconnected to the dischargepipe in direction of the flowof water at a point between75 - 450 mm from trapcrown.Vent stack connected to thedischarge stack near to thebend to remove compressedair at this point
  48. 48. The single stack systemReduces the cost of soil and wastesystems.Branch vent pipes are not requiredTo prevent loss of trap water seals:-The trap water seals on the wastetraps must be 76 mm deep.The slopes of the branch pipes are:sink and bath, 18 to 19 mm/m;basin 20-120 mm/m; WC 18 mm/m(min.).Vertical stack at 200 mm below thecentre of the WC branchconnection.
  49. 49. Modified single stack system Close grouping of the sanitary appliances  install the branch waste and soil pipes without the need for individual branch ventilating pipes. To prevent the loss of trap water seals  WC branch pipe min. 100 mm bore and the angle θ = 90.5° to 95°. To prevent the loss of trap water seals  basin main waste pipe min. 50 mm bore and the angle θ = 91° to 92.5°. Five basins or more / length of the main waste pipe exceeds 4.5 m  a 25 mm bore vent pipe connected to main waste pipe at a point between
