Safety distances for Boundary Walls & Drains

  • The minimum required distance from drains is 2m, irrespective of the number of cylinders.
  • Where not more than two cylinders are used, the minimum distance from a boundary is 1m, unless the boundary is a firewall, in which case the cylinders may be placed against the boundary.
  • Where more than two cylinders are used, the minimum distance from a boundary is 3m, unless the boundary is a firewall, in which case it may be placed directly against the boundary.
