Description
1 Australia Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT SURCHARGE GULLY PLUG.
THE FOLLOWING STATEMENT IS A FULL DESCRIPTION OF THIS INVENTION, INCLUDING THE BEST METHOD OF PERFORMING IT KNOWN TO ME.
2 SURCHARGE GULLY PLUG This invention is in response to the problem of water ingress into Authorities Sewers not addressed by presently available fittings.
Under AS 3500.2.1 (Performance requirements) Clause 7.2 Sanitary drainage system A sanitary drainage system using water borne waste disposal shall be designed and constructed to prevent stormwater entering the sewerage system.
Under AS 3500.2.2 (Acceptable solutions) Clause 4.5 require that a Reflux valve shall be installed where the minimum height of the Overflow Relief Gully (ORG) and the lowest fixture specified in clause 4.6.6.6 cannot be achieved. Cl 4.6.6.6 requires that the top of the ORG shall be 150mm below the lowest overflow point of the fixture connected to that drain. The height of the top of the ORG (4.6.6.7) shall be 75mm above the surrounding ground or a lesser amount if in a paved area, where it shall be finished at a level so as to prevent the ponding and ingress of water.
Some areas served by Authorities Sewers are flood prone and some sites because of topography will render the gully subject to flooding after the construction or earthworks are complete.
oo..
:i In some instances building Authorities require that the finished floor level be at or above a minimum flood height. However flood heights can vary because of existing or changed S:physical conditions including adjoining or adjacent property constructions or earthworks.
These conditions may then allow flood water to enter the sewer even though the requirements of 4.6.6.6 4.6.6.7 have been met. Ie The installation of a reflux valve will not stop floodwater ingress!.
The use of this invention should overcome this anomaly and save untold costs to infrastructure.
The invention comprises a simple sealing washer which seals the gully top and prevents water from entering, this sealing washer is connected to a lightweight floatation device shaped to allow self centering in the gully. In this version it will be of uPVC,-DWV however it may be manufactured of any material approved by the relevant authorities.
In another variation to this invention, simple non-return valves would be incorporated to allow ventilation whilst preventing water ingress. It could also comprise a restraining lead to stop the device washing away if a surcharge and flood occurred at the same time.
3 To assist with understanding the invention, reference will now be made to the accompanying drawings which show examples of the invention.
In the drawings Figure 1 shows the Surcharge Gully plug in the closed position Figure 2 shows the Surcharge Gully plug in the surcharge position.
Referring to figure 1 it can be seen that the Surcharge Gully plug comprises a simple sealing washer 1 connected to a floatation device (of any shape that will allow the device to self center) 3 it also has a capping piece 2 (which may be integral with 3) to support the sealing washer 1 which is seated on the gully.
Under normal circumstances there would be no need to vent this valve as the light weight allows small amounts of air to pass, however if different materials were required or airlocking were a problem then simple non return valves would be added.
Referring to figure 2 it can be seen that the Surcharge gully plug is in the surcharge position as it has floated out of its seat and is allowing sewage to overflow.

Claims (3)
1. A Surcharge gully plug comprising a sealing washer supported by a capping piece, all connected to a floatation device shaped to self center inside a gully automatically and seal the gully from stormwater ingress.
2. The Surcharge gully plug of claim 1 wherein is included non return valves to allow ventilation but not ingress flooding.
3. The Surcharge gully plug in claim 1 or 2 or a combination of 1 2 wherein is included a lead which will be fixed to the gully to restrain from loss. *i a...i a a Robert Stephen Morton 13 September 1999
