Overflow Relief Gulley

Have you ever wondered what this is in your garden?

Perhaps you have seen ‘ORG’ on a drawing.

Well the answer is it’s called an Overflow Relief Gully. It needs to between the house and the connection to the main sewer.

An ORG is a vital part of protecting your house against Sewage blockages in the main causing an overflow inside your house.

The grate is set 150mm below the level of the lowest waste water fitting in your house. Normally the shower drain or Floor Drain. ( In cases where the 150mm minimum height cannot be achieved, a reflux valve should be installed in addition to the ORG)

In the event of a sewer blockage the sewage can flow out of the ORG. Not very nice!…….. but much better than flowing out across your floor.

To make sure it works when you need it:

  • DON’T landscape over it!
  • DON’T put a plant pot …… or anything else, on top of it!
  • DON’T fasten the grate down! 
  • DON’T allow storm water to flow into it! 

 

House Construction – The Frame

The  Internal Frame is the key structural element in most Brick Veneer House Construction.

In more lightweight structures such as timber cladding and lightweight render it takes on an even more of the structural loads.

The overall frame is composed from a number of individual wall panels, which when fixed to the base, and fastened together, form a rigid box like structure.

Structural Loads

The frame carries several main structural loads:

  • It takes the load of the roof, and any upper floors, down to the foundation.
  • It resists the wind trying to push the whole building over.
  • It provides lateral support for the brick walls.
  • Holds the windows in place.
  • It gives a secure fixing point for the internal wall and ceiling lining boards.
  • In the case of weatherboard or lightweight render construction it supports the outer skin of the building.

Additional Functions

  • Provides a route and fixing points for cables and pipes.
  • Retains insulation.
  • Supports cupboards and shelves.
  • Fixing of building wrap.
