Project on drainage system vartika khandelwal m.sc. i.d. 3rd sem.

  1. 1. Project Report on Drainage System At Dezyne E’cole College,Ajmer Submitted to : Dezyne E’cole College Towards The Partial fulfilment of the Master’s of Science in Interior Designing By Vartika Khandelwal M.sc.I.D. 3rd Sem. Subject : Advance Building Services
  2. 2. DRAINAGE SYSTEM INTRODUCTION : As explained earlier, potable water supplied to a buildings is distributed to various areas like kitchen, bath, W.C. etc. through a network of pipes provided with plumbing or sanitary fittings at their terminal ends. Adequate arrangements are required to be made for quick collection, conveyance and disposal of used water from the fittings without any risk to the health occupants. It is also essential that the rain or storm water from the roof and paved areas of building and the ground surface is suitably collected and discharged without flooding the area. The Term Drainage or sewerage includes the system of removal of sullage or waste water (from floor traps, kitchen, bath, and wash basin), soil water (from W.C. and urinals) and storm water from a building and conveying the same upto its ultimate point of treatment and disposal. The system of drainage can be broadly divided in two parts. Drainage System Drainage below the Ground Drainage above the ground Combined system Separate system Partially combined system Drainage System Below the Ground Drainage System Above the Ground
  3. 3. TYPES OF PIPES The pipes used in Drainage system may be of cast iron, reinforced concrete, pre-stressed concrete, mild steel, wrought iron, asbestos, P.V.C.. or stone ware. Minimum Size of pipes commonly used in house drainage are as under : 1. Underground Horizontal pipes laid to slope………………......100mm dia. 2. Vertical soil pipe (Above Ground)………………………………100mm dia. 3. Vertical waste pipe (Above Ground)……………………...50 to 75mm dia. 4. Branch soil pipe……………………………………………..60 to 75mm dia. 5. Vent pipe……………………………………………………………50mm dia. 6. Rain water pipe…………………………………………………….75mm dia. 7. Waste pipe from individual kitchen, sink, washbasins etc…….40mm dia. Drainage System Below the Ground Stoneware Pipes Cement Concrete Pipe C.I.

  4. 4. TRAPS TRAPS : A Trap is a fitting provided in a drainage system to prevent entry of foul air of gases from the sewer or drain into the building. The barrier to the passage of foul air is provided by the water seal in the trap. In its simples form a trap is merely a double bend or loop in the sanitary fitting, the depth of water seal being the distance between the top of the first bend and the bottom of the second.

  5. 5. TYPES OF TRAPS 1. Floor Trap or Nahani Trap : Trap Provided in floors to collect used water from floors of bathroom, kitchen or washing floor etc. are known as floor trap. Floor Trap 2. Gully Trap : Gully trap is a deep seal trap which is provided on the external face of wall for disconnecting the waste water flowing from kitchen, bath, wash basin & floors from the main drainage system. The deep water seal forms a barrier for preventing the passage of foul air from house drain to the inside of the building.

  6. 6. During My Residential project I supposed to give the Drainage system in the house which was connected to the each floor of the house and at the same time connected with the underground floor level for septic or sewerage water. The Detail specification are as follows : Main Water Supply Pipe Distributer Water Pipe Waste Water Pipe Soil Waste Water Pipe
