Blocked Drain Guys 56 (640x427)

Do you face stormwater drainage issues and flooding?

When it rains in Sutherland Shire and your yard floods, your driveway turns into a river, or water pools against the house — your stormwater drainage system is not doing its job. The Blocked Drain Guys clear blocked stormwater drains, repair damaged stormwater pipes, and fix drainage problems across the Shire and Sydney.

Common Stormwater Problems in the Shire

  • Blocked stormwater pits — Leaves, silt, sand, and debris fill up stormwater pits and grates, especially in autumn. Once blocked, water has nowhere to go.
  • Tree root intrusion — Same as sewer pipes, tree roots find their way into stormwater pipes through joints and cracks. Fig trees and paperbarks are common culprits across the Shire.
  • Collapsed or cracked pipes — Old terracotta and concrete stormwater pipes deteriorate over time. The sandstone geology can cause ground movement that shifts and cracks pipes.
  • Undersized drainage — Some older Shire homes have stormwater systems that were never designed for heavy Sydney rainfall. They simply cannot handle the volume.
  • Salt air corrosion — Properties near the coast in Cronulla, Caringbah, and Kurnell can see accelerated corrosion of metal fittings and connections in the stormwater system.

Stormwater Drainage FAQs

Common questions about stormwater systems answered by Sydney drainage plumbers

Stormwater drains carry rainwater from roofs, driveways, and gardens to the street or local waterways. Sewers carry wastewater from toilets, sinks, and showers to treatment plants. They’re separate systems and must never be connected.

Your stormwater drain is likely blocked with leaves, sediment, or tree roots. The pit fills faster than water can drain away. We clear blockages using high-pressure jetting and can install grates or filters to reduce future buildup.

No. It’s illegal in Sydney to connect stormwater to sewer lines. Stormwater must go to dedicated stormwater drains, absorption trenches, or detention tanks. Illegal connections can result in fines and mandatory disconnection.

At least annually, or more often if you have large trees nearby. Regular cleaning prevents blockages that cause flooding during heavy rain. We recommend inspecting your system before storm season.

Water can back up into your property, flood your yard, damage foundations, or seep into your home. Proper maintenance and correctly sized drains prevent most storm-related drainage failures.

Yes. We design and install stormwater systems for extensions, new driveways, and landscaping. All work connects to council-approved discharge points and complies with Sydney plumbing regulations.
