Installing an ORC Overflow Relief Cap is a crucial step in preventing stormwater infiltration into the sewer system through your Overflow Relief Gully (ORG)

The ORC Overflow Relief Cap was explicitly designed to prevent rainwater from infiltrating the sewer system via non-compliant ORGs. It also can be installed in ORGs to prevent insect and vermin infestation plus odour emissions, promoting a healthier living environment.

The ORC Overflow Relief Cap was explicitly designed to prevent rainwater from infiltrating the sewer system via non-compliant ORGs. It also can be installed in ORGs to prevent insect and vermin infestation plus odour emissions, promoting a healthier living environment.

Why is an ORC Overflow Relief Cap needed?

Overflowing stormwater and overland ground flow during storms or heavy rainfall are common issues on the Gold Coast and throughout South-East Queensland. The problem stems from ground flow water during serious rainfall events entering sewer drains through non-compliant or illegal house overflow relief gullies (ORGs), which results in rapid flow infiltration.

Rapid flow infiltration is a significant environmental concern and can potentially cause catastrophic damage.

When stormwater infiltrates sewers, it can cause sewer infrastructure failure, resulting in sewage overflow through manholes and into natural water sources such as creeks, rivers, and lakes, ultimately reaching the sea.

The accompanying image highlights the problem with an overflow relief gully or ORG positioned slightly below the level of the path, allowing rainwater to flow directly into the ORG grate and the sewer house drains.

During storms, the rate of rapid flow infiltration by overland rainwater flows peaks quickly, with up to 40% of stormwater infiltration into sewers originating from non-compliant ORGs.

Benefits of Installing an ORC Overflow Relief Cap

Overflow Relief Gullies (ORGs) are essential plumbing infrastructure that prevents sewage blockages from flowing into any building through floor waste drains and shower drains. ORGs are a requirement in every building.

Installing an ORC is a simple yet effective solution to prevent stormwater from infiltrating the sewer system and causing sewerage overflow during heavy rainfall.

The ORC overflow relief cap is an anti-filtration device that does not allow overland water flow during storms to enter the sewer system via the ORG. If your sewer house drains block, the ORC cap is ejected upwards by the surcharging sewerage flow to allow ORG to function as designed, with the sewerage overflowing onto the ground rather than into your bathrooms.

The benefits of installing an ORC overflow relief cap are numerous.

  • Expensive alterations to an overflow relief gully to make it legally compliant are eliminated by simply installing an ORC overflow relief cap into the existing non-compliant ORG
  • It reduces the risk of sewerage overflow via a non-compliant ORG, which can cause health hazards, environmental damage, and property damage
  • It helps to vent the ORG to prevent siphonage in the ORG trap, with air flowing in via the vent inlets on top of the cap
  • The ORC prevents snakes, rodents, cockroaches, cane toads, insects and other vermin from entering your home via the ORG
  • Sewer odour emissions from the ORG are eliminated, especially in situations where alterations to the house now have the ORG situated in a garage or patio

Overall, installing an ORC overflow relief cap is an innovative and cost-effective investment that benefits homeowners, the environment, and the community as a whole. Installing an ORC overflow relief cap adds value to the property by ensuring the safety and integrity of the plumbing system, potentially increasing its resale value.

Installation of an ORC is Straightforward and Immediately Effective

If you have an ORG overflow relief gully illegally at your home or are experiencing sewer odour emissions and need an ORC installed, Whywait Plumbing can do it for you.

The installation process can be completed quickly, usually within an hour or so, with minimal disruption to your home. Once installed, the ORC will provide reliable protection against sewer overflows caused by heavy rainfall events, giving you peace of mind and a more efficient plumbing system.

Here’s how the process works in simple terms:

First, our plumber will inspect the ORG and ensure it’s in good condition.

Next, they will remove the existing grate from the ORG.

The plumber will then install the ORC, which is designed to fit securely onto the top of the ORG. This installation will require the use of specialised equipment and tools.

Once the ORC is in place, our plumber will test the cap to ensure it’s working correctly. They will do this by simulating a sudden influx of water, which will trigger the ORC to release water at the correct pressure level.

Finally, our plumber will clean up any mess created during the installation and leave your property clean and tidy.

With the ORC installed, you can rest easy knowing that your home’s plumbing system is protected from potential backups and overflows caused by heavy rainfall. If you have questions about the installation process or want to schedule an appointment, Whywait Plumbing’s friendly team is always happy to help.
