Four things that set Glenelg apart
61.1% flats or apartments
At the 2021 Census, flats and apartments made up 61.1% of the suburb's occupied homes, semis and townhouses 20.8%, and separate houses just 15.8%.
Lots of tenants
41.9% of Glenelg homes were rented, against 27.6% statewide, and only 14.5% had a mortgage.
No bore water in parts of Glenelg
Since 20 December 2018, a Groundwater Prohibition Area set by the EPA has covered areas of Glenelg, Glenelg East, Glenelg South and Glengowrie.
A treatment plant since 1933
SA Water's Glenelg wastewater treatment plant has run since 1933, with upgrades in 1945, 1962, 1973 and 2002.
Leaks in a unit block
In a block of flats, the pipe that's leaking may serve more than one home. Before a plumber opens a wall or ceiling, tell the strata or community corporation manager, and the unit owner upstairs if water is coming from above. Renting? Your agent or landlord is the first call.
A specialist in leak detection can often find the source without cutting into several units. Our hidden leaks page explains the methods.
Bore water: check before you use it
Groundwater under the prohibition area is contaminated, the EPA says, partly from a former dry cleaner, and it will stay that way for the foreseeable future. Mains water and rainwater tank water are not affected. If your property has an old bore, don't connect it to a garden system or tap without checking with the EPA first. Buyers are told about the prohibition in the Form 1 statement.
Renovating an older home
Glenelg has heritage-listed and character homes. In one 2025 Council assessment report, an 1890s semi-detached Local Heritage Place on Gordon Street carried overlays for heritage, character, general flooding, regulated trees and stormwater management.
Its recommended conditions show what Council can ask for. The stormwater system had to cater for a 5 year rainfall event, send no more than 10 litres per second to the street, hold any excess on site, and discharge nothing onto the neighbours. Conditions are set for each application, so check yours before a plumber prices the drainage.
Sewer, SA Water and the treatment plant
Each year, a pipeline from the Glenelg plant returns 2.8 gigalitres of treated wastewater to central Adelaide, mostly to water parks, gardens and sporting grounds. We couldn't read SA Water's own rule on where its sewer ends and your drain begins, so ask SA Water if the fault sits near the boundary. More help: blocked drains in Adelaide, hot water, emergency plumbers and our stormwater page.
What we would do
In an apartment, stop the water first, then talk to the strata manager before anyone opens a wall: who pays depends on whose pipe it is. In a house, check whether a renovation approval already sets stormwater conditions before you sign off a drainage plan. And leave any old bore alone until you've checked the EPA's prohibition area. Then let us match you with the right specialist.
