Mount Waverley details that change the job
Owned outright
41.9% of occupied homes in the suburb were owned outright at the 2021 Census (Victoria: 32.2%). 68.6% were separate houses and 21.5% flats or apartments.
Canopy tree permits
Monash needs a planning permit to remove or lop a canopy tree at least 5 m tall with a canopy 4 m wide, within 6 m of the front boundary or 4.5 m of the rear where there's a home.
Low hardness
The suburb falls in Yarra Valley Water's Mitcham and Glen Waverley sampling areas, which averaged 17 and 15 mg/L hardness in 2025-26.
Overflowing drains
VICSES's Monash guide says heavy rain can overflow stormwater drains, and that areas developed before the 1970s are generally more likely to flood in an extreme storm.
Digging near a big tree
A new sewer or stormwater line often has to pass a tree. Taking that tree out, or lopping it, can need a planning permit under Monash's canopy tree controls. Some areas also sit in a Vegetation Protection Overlay, where a permit applies to vegetation higher than 10 m with a trunk circumference over 50 cm at 120 cm above the ground.
Dead trees are exempt, and only the part of a tree posing an immediate risk can come off without a permit. So check with Council before a quote assumes the tree can go. Where roots are already inside the pipe, a tree root drain specialist or pipe relining may mean less digging.
Yarra Valley Water's pipes and yours
Yarra Valley Water owns the meter and stop tap, and it repairs the pipe from the main to the meter even though it doesn't own that pipe. From the meter to the house, the plumbing is the owner's. For sewer work, Yarra Valley Water's two descriptions of its boundary differ, so get it to tell you where its pipe stops at your address.
Gas hot water after 1 March 2027
With so many owner-occupiers, the state rule is worth knowing early. From 1 March 2027, a gas hot water system that reaches the end of its life has to be replaced with an efficient electric option, such as a heat pump. A working gas system can stay, and repairs are still allowed (check current rules). Our Melbourne hot water page compares the options.
What we would do
If drain work has to go near a large tree, ask Monash about the tree before you accept a quote, then have the plumber price it two ways: around the tree, and with the tree removed under a permit. If your gas hot water system is near the end of its life, decide on its replacement now rather than on the cold morning it fails. Either way, only the plumber who takes your job gets your contact details.
