Stormwater & Drainage in Aldinga Beach
One of the south's fastest-growing areas. We complete the stormwater that building contracts often leave out.
Local drainage in Aldinga Beach
Aldinga Beach and the wider Aldinga district are growing about as fast as anywhere in southern Adelaide, with new estates going in year after year. The catch most new owners hit is that stormwater plumbing usually isn't in the building contract. Homes are handed over with downpipes that stop at ground level and a yard that becomes a lake in the first real winter. Completing those systems is core work for us across the new estates.
The terrain is mostly flat and sandy, which sounds forgiving but brings its own problems: with little natural fall, water needs deliberate grading to move anywhere, and parts of the district sit over a seasonally high water table near the Washpool and coastal flats. Good drainage here is about creating fall where nature didn't provide it.
What we see in Aldinga Beach
- New builds handed over without stormwater. Downpipes that end at the ground and no street connection — the most common call we get from the new estates. We complete the system from roof to discharge point.
- Flat blocks with no natural fall. Water won't move without grade. We design pipe runs and surface drainage with deliberate fall, and use pumps where gravity can't do the work.
- Seasonally high water table. Near the coastal flats, winter groundwater limits soakage. Systems here need to move water off the block, not just into the ground.

Aldinga Beach stormwater questions
Our new Aldinga Beach home has downpipes that just stop at the ground — is the builder responsible?
Check your contract, but in most volume-build contracts stormwater beyond the roof plumbing is excluded — it's legal and very common. Either way the fix is the same: a complete stormwater system connecting downpipes to a compliant discharge point. We do these regularly across the new estates.
Our yard turns into a pond every winter — the block is completely flat. What can be done?
Flat blocks need engineered fall: correctly graded pipe runs, surface grates at the low points, and sometimes a sump and pump to lift water out. Once the water has a designed route, a flat block drains as well as a sloped one.
Do you cover Aldinga, Port Willunga, and Sellicks Beach too?
Yes — we cover the whole Aldinga district and down the coast, and we're based about fifteen minutes away in Seaford.
Nearby areas we cover
Aldinga
The original township inland of the beach — older homes and infill on established streets, sitting alongside the new estates.
Port Willunga
Cliff-top coastal streets where salt air is hard on gutters and runoff needs a managed path before it reaches the cliff edge.
Sellicks Beach
On the flats beneath the Sellicks escarpment — heavy rain coming off the scarp crosses these blocks on its way to the sea, so interception drainage matters more than the flat ground suggests.
