Maintaining Your Gold Coast Stormwater Drains Prevents Flooding When It Rains & Rains & Rains Even More

Whywait Plumbing are your Gold Coast stormwater drains specialist plumbers, designing, installing, rectifying, maintaining stormwater drains and clearing blockages for over 43 years.

Stormwater is regrettably the most ignored aspect of the plumbing systems that are part of every property. Sadly it is frequently the cause of the most serious and expensive property damage problems.

Unfortunately, the installation of the stormwater drains is not effectively regulated or enforced on the Gold Coast. It is unfortunate for many property owners that their stormwater drains were designed and installed by under-qualified contractors with minimal concern for or knowledge of pipe sizing and design.

City of Gold Coast’s Plumbing & Drainage Inspectors DO NOT inspect your stormwater drains. In Queensland, stormwater drains are inspected and certified by private building certifiers, rather than council plumbing inspectors which in our experience frequently means they are never inspected to ensure they are compliant or fit for purpose.

When severe summer storms arrive or the increasingly common arrival of east coast lows you understand and appreciate your stormwater drains. These weather events can see us receive more than 100mm of rainfall in a single hour, which results in flash flooding, rapidly.

Maintaining your Gold Coast stormwater drains is critical to prevent the possibility of rainwater infiltration inside your home or business premises.

What Are Stormwater Drains?

Every property has a stormwater drainage infrastructure system that is required to be designed and installed in accordance with AS/NZS 3500.3:2018  Plumbing and Drainage – Stormwater Drainage.  This standard sets out the minimum requirements for the design, materials, installation, and testing of the three core components that make up your properties stormwater drainage system:

  • a roof drainage system
  • a surface drainage system
  • subsoil drainage system

Every drainage system listed above is designed to collect your rainwater runoff from your roof, pathways, driveways, gardens and lawns to deliver the rainwater to a legal point of discharge. The legal point of discharge will be one of or a combination of the following:


  • out onto the street with connections cut into the existing concrete kerb and channel
  • an existing stormwater collection pit which is connected to the councils stormwater drainage system
  • You cannot redirect your stormwater runoff away from your property and adversely affect neighbouring properties. It is your responsibility to manage rainwater that falls onto your property.

Maintaining Your Gold Coast Stormwater Drains

Similar to most of our plumbing infrastructure, stormwater drainage systems are mainly underground and out of sight. Regrettably, they are always out of mind too, until it’s pouring down with rain and your Gold Coast stormwater drains fail to function.

Legally you are responsible for maintaining all of your stormwater drainage infrastructure within your property. This responsibility includes the kerb adapter connections out on the street or the connection into a council collection pit.

Remember the stormwater drainage infrastructure is all-encompassing from the roof right through to the discharge points into council infrastructure. Every bit of water that flows from stormwater off your roof, paths, driveway, gardens, and lawns goes into council stormwater drains that connect to local creeks and rivers that all flow out to sea.

Maintaining your stormwater drains is simple, Don’t wait for a disaster to unfold when it’s pouring rain. Maintenance of stormwater drains carried out annually potentially protects your family, your local environment and your local waterways. Above all, it helps eliminate the costs of expensive emergency repairs and ensures your stormwater drains have the capacity to handle summer storms.

Talk to us today about a maintenance program for your stormwater drains, that start with your roof. As we all learn the hard way, “prevention is better than the cure”. Simply the proverb means it’s easier to stop something happening in the first place than to repair the damage after it has happened.

Where blocked or broken stormwater drains are concerned there is not a cure, just a heap of pain in the hip pocket.

So impressed with this company, they were prompt, professional, friendly and fixed our problem so fast! Massive storm water issues that another plumber attempted to fix and failed! Highly recommended and will always use them from now on! Thanks Nathan and team!

Why Your Gold Coast Stormwater Drains Are Faulty?

As with most of our plumbing infrastructure, stormwater drainage systems are out of sight and out of mind until we get torrential downpours. When storms or torrential rain events occur the design and installation faults of stormwater drains are exposed.

  • Under sizing of stormwater drains pipework infrastructure
  • The use of low grade 90mm stormwater or agipipe in the ground which is neither large enough or strong enough to cope with torrential rain
  • The running of stormwater drains to undersized rubble pits with no overflow
  • Lack of fall in stormwater drains or frequently back fall where the pipe is trying to drain uphill
  • Undersized of in-ground stormwater sumps or pits
  • Non-existent or substandard waterproofing of retaining walls
  • Poor design and under-sizing of spoon drains and grated drains that are supposed to remove stormwater runoff 
  • Combining of roof water stormwater with overland stormwater runoff which is undersized and poorly designed
  • Lack of maintenance of stormwater drains and all associated infrastructure

Problems From Poor Installation of Stormwater Drains

The damage caused by substandard stormwater drains is extensive. It has serious ramifications for the condition and lifespan of buildings and the buildings construction materials. All of which blow out and increase maintenance costs. Because most stormwater infrastructure is underground it can be expensive to investigate and rectify.

At Whywait Plumbing we continually witness substandard stormwater installations needing expensive rectification work undertaken. Most of this work would be unnecessary if building certifiers inspected the drains correctly compounded by poor design and installation undertaken to a cost and not to the standards. More frustrating is seeing these mistakes compounded by substandard repairs by unqualified and unlicensed handymen once again employed as cost-cutting factors by property managers and property owners.

Significant problems caused by substandard stormwater design, installation and maintenance include:

  • Water ingress in reactive soils that results in structural damage
  • Encourages termite infestation
  • Creates erosion under concrete slabs and around the foundations of the building
  • Erosion and undermining of gardens and lawns
  • Contamination of swimming pools
  • Damage to timber framing, flooring and other building materials
  • Flooding of the property
  • Water ingress into the living areas through retaining walls
  • Damage to roof support structures
  • Blocking of stormwater drains and pits with soil and debris
