Mount Eliza, in plumbing terms
Owner-occupied houses
At the 2021 Census, 91.9% of occupied homes in the suburb were separate houses. 45.3% were owned outright, well above Victoria's 32.2%, and just 8.4% were rented.
Four creeks
VICSES names Kackeraboite, Ballar, Earimil and Gunyong Creeks as Mount Eliza's main waterways, and counts four significant floods between 2010 and 2022.
Fast, local flooding
Flooding can arrive within hours. VICSES puts it down to stormwater drains that can't carry the rain, and ground that can't soak it up, which more buildings and less green space make worse.
South East Water
Mount Eliza is on South East Water's supply list, so its rules cover the water meter and the sewer branch to your property.
When the drains can't keep up
For a minor flood, VICSES expects water coming up through drains in nearby streets and some backyards affected. If rain pools against your house, check the gutters, downpipes and pits along your own stormwater line first, since they're yours to keep clear.
Paving a garden bed leaves rain less ground to soak into, the same effect VICSES describes across the suburb. A new driveway or patio may need more drainage than the old yard had, and a stormwater plumber can work out what's needed.
Sewer, or a system of your own?
The Shire keeps records of approximately 22,000 onsite wastewater systems across the municipality, and its plan doesn't single out Mount Eliza. So don't assume either way. If you're unsure, ask the Shire whether a system is recorded for your property, and see our septic systems page if one is.
Where a home is sewered, South East Water's part ends at the inspection opening, usually near the boundary, and the pipes from there back to the house are the owner's. On the water side, South East Water looks after the street pipes and the meter; from the meter to the house is yours.
What we would do
Before winter, clear the leaves from gutters and stormwater pits, and find your sewer inspection opening so it's easy to reach. If water bubbles up from the gully outside or the toilet gurgles while it rains, call a drain specialist rather than waiting for the next storm. Tell us what you saw and when, and the plumber who takes the job will contact you.
