Mitcham Council's just approved the Hampton Street Bridge replacement — that's barrier upgrades, footpath work, and stormwater improvements all in one hit. For Eden Hills, the bigger news is the $70,000 localised stormwater project that kicked off late January 2026, plus the completed investigation at 3 Trevor Terrace that confirmed groundwater issues tied to the ARTC rail network. We copped 14mm on May 2nd and another 15mm on the 4th — not huge, but enough to test any drain that's been quietly silting up since autumn. SA Water's also mid-way through the Eden Hills Inlet Control Project, a major capital upgrade to fix pressure and supply reliability across the hilly terrain here. If you're on the lower slopes near Murtoa Road or Willora Road, that combination of council drainage work and reactive clay soils means your stormwater system's under pressure right now. Call us before a slow drain becomes a flooded laundry.
City of Mitcham notes
“Hampton Street Bridge Replacement - Barrier, Footpath and Stormwater Improvements (Motion carried, 12 May 2026)”
City of Mitcham
Stormwater upgrades around bridge infrastructure can shift drainage loads — properties downstream may see changed flow patterns, and any excavation near old mains risks disturbing private connections.
“Murtoa Road and Willora Roads intersection safety upgrade (2025/2026) — kerb upgrades to direct stormwater to existing pits, footpath improvements”
City of Mitcham
Kerb work along Murtoa Road changes how stormwater reaches the pits — if your property fronts this stretch, watch for new pooling or backflow after the next decent rain.
“$70,000 Eden Hills Localised Stormwater construction project — tendered and commenced late January 2026; stormwater investigation at 3 Trevor Terrace completed, identifying groundwater issues from ARTC network”
City of Mitcham
Council's confirmed groundwater problems tied to the rail corridor — properties near Trevor Terrace may have subsoil drainage issues that aren't just about their own pipes.

Eden Hills profile
Eden Hills falls within the City of Mitcham local government area in Southern Adelaide, South Australia.
Murtoa Road, Willora Road, and Trevor Terrace are the streets where drainage headaches concentrate — council's already flagged groundwater issues from the ARTC rail network in that corridor. The housing stock splits between 1960s mid-century builds with earthenware sewers and copper supply, and 1990s–2000s infill on PVC. The older homes on Doreen Street and Dolorosa Avenue have established gardens with deep-rooted trees that crack earthenware joints every wet season. If you're in a newer build, the risk isn't age — it's undersized stormwater pits that can't handle the runoff from the clay soils around them.
When calls come in: Most emergency calls from Eden Hills come late afternoon and early evening — people get home from work, run the dishwasher or shower, and that's when a marginal sewer line tips over into a full blockage. Weekends after rain are also busy, especially on the flatter allotments where pooling becomes obvious.

Eden Hills Plumber FAQ
The council's localised stormwater project and SA Water's pressure upgrade shouldn't directly disturb private sewer or water lines, but any major infrastructure work can shift soil and change drainage patterns. If you're on Murtoa Road, Willora Road, or Trevor Terrace, watch for new damp patches in your yard or changes in water pressure after works crews move through. A plumber we dispatch can run a pressure test and camera inspection to confirm your lines weren't affected.
Slow drains after 14–15mm of rain usually mean one of two things: surface debris blocking your gutter-to-stormwater connection, or tree roots that have infiltrated your sewer line and are now swelling with moisture. Check your external gully traps first — if they're clear and drains are still sluggish, the blockage is deeper. A plumber we dispatch can jet the line and camera it to confirm whether it's soft debris or structural damage.
Original copper from the 1960s–70s fails from the inside out, so you won't see corrosion on the surface. Warning signs include green staining around joints, pinhole leaks that leave small wet patches on walls or ceilings, and a metallic taste in your water. If you've had one pinhole leak, expect more — the pipe wall is thinning throughout. A plumber we dispatch can pressure test the line and advise whether spot repairs will hold or if a full repipe is smarter.
In a 1970s home here, the failure sequence is usually: earthenware sewer first (root intrusion and joint cracks), then copper supply lines (internal corrosion), then cast-iron branch lines under the house (rust-through and scale buildup). Get a camera inspection of your sewer line every three to five years — that's where the expensive surprises hide. If your hot water unit is also original, it's well past its service life and should be replaced before it floods your laundry.
A blocked sewer clears with a jet or auger and stays clear for months. A collapsed sewer clears temporarily, then blocks again within days or weeks — often in the same spot. The only way to confirm is a CCTV camera inspection. A plumber we dispatch will run the camera after clearing the blockage to check for cracks, root mass, or pipe displacement. If the camera shows a belly or break in the line, you're looking at excavation or relining, not just another jet.
Eden Hills sits on Keswick Clay — highly reactive soil that swells when wet and barely drains. If your allotment is flatter than your neighbours or sits lower on the slope, water pools instead of running off. Check that your stormwater pits aren't silted up and that your ag drains (if you have them) are still connected and flowing. A plumber we dispatch can camera your stormwater line and check for blockages, collapses, or disconnected sections that are sending water into your subsoil instead of the street.
