Stormwater and Sewer Markouts
Know What’s Below Before You Start
Our stormwater and sewer markout services are designed to give you accurate, reliable information so you can dig safely, stay compliant, and protect essential infrastructure. At Locate Down Under, we make sure you don’t get caught off guard when digging or developing near stormwater and sewer systems. With years of hands-on experience, we know exactly how to uncover what’s hidden beneath the surface, helping you avoid unnecessary disruptions, environmental issues, and regulatory complications.
Why Stormwater and Sewer Markouts Matter
Stormwater and sewer lines are often buried beneath driveways, yards, footpaths or work sites and may not always appear on plans. Striking these underground services can lead to serious damage, costly repairs, environmental risks, and delays to your project. These systems are essential to both public health and stormwater management, so preserving their integrity is critical. That’s why we provide expert markouts based on real-time locating, not just utility drawings. We combine technology with experience to ensure every underground asset is identified and clearly marked before any ground is broken.

How We Locate
Stormwater and Sewer Infrastructure
We use a range of advanced locating tools including sonde transmitters, CCTV cameras, and acoustic tracing techniques to identify the path and depth of stormwater and sewer lines. Our process allows us to pinpoint manholes, junctions, bends and line paths with accuracy, providing clear markings on-site to guide excavation work. We begin with a detailed site evaluation to understand the layout and access points, then apply the most suitable locating methods depending on ground conditions and asset types. If required, we can also assist with access and inspection of difficult-to-reach areas, offering detailed visual confirmation and professional insight into your underground drainage infrastructure.

Yes. Dial Before You Dig provides plans from utility asset owners, but it doesn’t show the exact location of services on your specific site. Our team complements this by physically locating and marking the services using advanced tools.
While pipe locating focuses on detecting water, gas, and sewer lines, cable locating is used to trace electrical and telecommunications cables. Our team uses advanced electromagnetic locating technology to safely identify both live and de-energised cables on-site.
