Overflow Relief Cap

The ORC Overflow Relief Cap Prevents Stormwater Infiltration Into Sewer Drains

Overflowing stormwater and overland ground flow during storms or long rainfall events have always been a problem in Queensland. This is due to ground flow water flowing into the sewer drains through illegal or non-compliant house overflow relief gullies or ORG’s. This water flow is termed rapid flow infiltration.

Environmentally this rapid flow infiltration is potentially catastrophic.

Stormwater infiltration into sewers potentially leads to failure of sewer infrastructure resulting in sewerage overflowing through manholes onto the ground and flowing into creeks, rivers, lakes and out to sea.

With Queensland storms, rapid flow infiltration into sewers peaks quickly with an estimated 40% of all stormwater infiltration into sewers originating from non-compliant house overflow relief gullies or ORG’s.

The Environmental Solution

The solution for Queensland councils, water authorities, plumbers and individual households is the simple installation of an ORC anti infiltration Overflow Relief Cap.

The environmental benefits to the community of reducing rainwater infiltration into sewers  by installing an ORC are:

  • 40% reduction of rapid flow infiltration of rainwater into sewers from house ORG’s
  • reduction in sewer surcharge overflows during storms
  • reduced capital expenditure for Queensland councils and water authorities on sewer storage capacity
  • reduced capital expenditure on sewer pumping capacity
  • reduction in capital expenditure on sewerage treatment
