06 Sanitary Plumbing and Drainage

Design of sanitary pipework systems

A good sanitary pipework system should be designed and installed to provide the following attributes:

  1. Prevent the transmission foul air in to the building.

  2. Minimise the frequency of any blockage, and provided with adequate pipe access to enable the effective clearance of any such blockage.

  3. Provide efficient conveyance of discharge from sanitary, kitchen, laundry and wash-down facilities, to enable the correct function of each appliance.

  4. Where any sewer is likely to surcharge, minimise the risk of flooding to any part of a building where the floor level is located below normal ground level.

Sanitary discharge pipework should therefore be kept as short as possible, with few bends, and with adequate gradient.
