Upwey Is South East Water, Not Yarra Valley Water
Almost every suburb in the Shire of Yarra Ranges is served by Yarra Valley Water. Upwey is not one of them, and getting this wrong costs people a morning on hold with the wrong utility.
South East Water's own annual drinking water quality reporting lists its localities by water quality zone, and Upwey appears inside the Belgrave zone alongside Belgrave, Belgrave Heights, Belgrave South, Selby, Tecoma and Upper Ferntree Gully. That is the retailer's own document naming the suburb, which is about as settled as this sort of question gets. Sewer faults in Upwey go to South East Water on 13 28 12.
South East Water is also actively at work under Upwey's streets. Its Guy Street sewer renewal project set out to replace the sewer rising main in Guy Street and Forest Park Road to improve reliability and reduce the risk of spills, with construction recommencing from October 2025 for around four weeks. A second works page covers Bayview Avenue. It is also the same retailer that built the pressure sewer scheme over at Belgrave and Selby, though that scheme itself covers Belgrave and Selby rather than Upwey.
The word to notice in that project description is rising main. A rising main is pumped, not gravity-fed, which is what you would expect in country where the ground refuses to co-operate with a straight fall. It also means that where pumped sewerage serves a property, what goes down the drain matters more than it would on a gravity line, because a pump station has far less tolerance for wipes and rag than a large gravity sewer does.
One Fitting or All of Them? The Question That Sorts It
Count the fixtures before you ring. It takes half a minute and it tells a plumber more over the phone than any description of the noise ever will.
Five Things to Do While You Wait
- Stop putting water into the system. Taps off, and keep them off. Every litre added has to leave somewhere, and indoors the lowest opening is usually a shower base.
- No washing machine, no dishwasher. Both discharge a large volume in one push, which is what turns a slow line into a spill on the floor.
- Find the grated fitting nearest the house. That is the overflow relief gully, deliberately set lower than every indoor fixture so a surcharge escapes outside instead of through a bathroom. It should never be paved over, planted out or covered.
- In a downpour, clear the grates at the bottom of the drive. On a sloping Upwey block that one grate is often carrying the whole hillside, and a mat of leaves on it is a two-minute job with a large payoff.
- Skip the supermarket drain cleaner. It does nothing to roots or set fat and leaves a length of caustic liquid for whoever opens the line next.
Wastewater coming up indoors is an emergency at any hour. Ring 0425 226 636.
The Upwey Year — When the Calls Come
🍂 Autumn
Leaf and bark load is heavier here than on the flat, and it lands on roofs, in gutters and in every yard grate at once. Clearing them in April is the single best-value hour anyone spends on an Upwey property.
🌧️ Winter
Sustained rain saturates ground that was already steep. Stormwater calls peak, and so do the slow-moving problems where a line has shifted rather than blocked.
🌱 Spring
Root growth accelerates and the storm of late October is not a hypothetical here. A sewer cleared in July will often close again now if the entry point was never sealed.
☀️ Summer
Dry ground drives roots toward the wettest thing available, which is usually a weeping joint. It is also the best window for relining and for a stormwater check before autumn.
Who Is Responsible for a Blocked Drain in Upwey — You, the Shire, or South East Water?
Yarra Ranges puts the private side plainly: property owners are responsible for all stormwater drainage within their property along with the section of drains running from the property to the approved point of discharge. Everything on your side of that point is yours to maintain and repair.
What the council also does, and this is the part worth reading if you live on a hill, is spell out what that discharge point is allowed to connect into. The list runs to four things: underground drains or kerbs within the street, an underground drain inside an easement, a private drain managed by an owners corporation, or a Melbourne Water distribution drain where explicit permission from Melbourne Water has to be sought.
The kerb entry matters in Upwey. On steep streets a legal discharge is frequently to the kerb rather than to a pipe, which means your stormwater is designed to run out across the nature strip and down the channel. If that outlet silts up, is buried by garden mulch or is sealed over during a landscaping job, the water has nowhere legitimate to go and it will find somewhere illegitimate instead, usually against a footing.
Council is also clear that flooding or water flow issues between adjoining properties should be sorted out between the private owners involved. It is not the referee in a fence-line water dispute. What a plumber brings to that conversation is evidence, because a camera survey shows where water is genuinely travelling rather than where each neighbour believes it is.
Renting in Upwey? Pipework is part of the building, so repair generally falls to the owner, with the obvious exception of a blockage created by something that should never have gone in. Tenants, use email rather than a phone call, because an email is dated and a phone call is not, and take photographs of anything visible. Owners and managers, ask for the footage, because it is the only thing that reliably distinguishes a failed pipe from a misused one. Our guide to who is responsible for a blocked drain works through the detail.
Warning Signs on an Upwey Property
- Noise crossing between fittings — flush the toilet and the basin answers. See gurgling drains.
- Water running across the surface instead of into a pit — the classic sign that a grate or its outlet has silted up on a slope.
- The outside grate lifting during rain — your overflow relief gully releasing a surcharge. Urgent, not decorative.
- Odour that shifts with the weather — see why drains smell.
- A drain that only misbehaves after heavy rain — often stormwater getting into a wastewater line, or a defect that only surcharges when the system is loaded.
- Cracked paving, a tilting retaining wall or a step in the lawn — ground movement, and rigid pipe underneath it does not bend.
- The kitchen slowing month by month — cooled fat closing the branch from the wall in. See kitchen sink draining slowly.
How We Clear a Blocked Drain in Upwey
1️⃣ Work out which system it is
Is it storm or waste, is it a single branch or the pipe the whole house feeds, and what is the nearest opening. Anything shared gets the CCTV camera first.
2️⃣ Choose the tool for the material
Something soft and close to the fixture will normally come away on a drain machine. Roots, silt, grit and set fat want 5000 PSI jetting, which strips the material off the barrel rather than boring through the centre of it.
3️⃣ Record the finished line
Once it is flowing the camera goes back in, which on a hill block matters more than usual because it shows whether the pipe has moved as well as whether it is clear.
4️⃣ Say what caused it
A dropped joint, a belly, a fracture, or simply a grate that has been buried for a decade. You get it straight, including the times when doing nothing yet is the right answer.
Repeat Blockages: When an Upwey Line Wants Relining Rather Than Digging
Clearing the same run twice in the same place is not maintenance, it is a subscription. If a line has closed over again in the same spot, the pipe is the problem rather than what grew in it.
Relining rebuilds it from the inside out. Resin is carried into the bad length on a flexible sleeve, inflated hard against the old barrel and left to set, and what you end up with is one unbroken new surface where the cracks and open collars used to be. Nothing above ground gets opened, which on an Upwey block is the difference between a day of work and an excavation running down a slope past a retaining wall. More on pipe relining, and a straight comparison of relining versus replacement.
What We Unblock in Upwey
🌧️ Blocked stormwater
Silted pits, buried kerb outlets, choked downpipe lines and grates carrying more hillside than they were sized for. See stormwater drains.
🚽 Blocked toilet
Usually wipes and paper, or a fault further down the line that the toilet happens to announce before anything else does. On pumped sewerage, wipes are a bigger problem than most people realise. See blocked toilets.
🪣 Blocked sink or basin
Fat narrows a kitchen branch a little every year until one rinsed tray finishes it. Basins do the same thing with hair and soap. See blocked sinks and blocked basins.
🌳 Blocked sewer
Every fitting stops because they all feed one pipe. Wants jetting and a camera rather than repeated poking. See blocked sewers.
🚿 Slow shower or floor waste
If nothing else in the house is affected, expect hair and soap within arm's reach of the waste. See blocked showers.
🏪 Shops and community buildings
Main Street premises, halls and clubrooms have their own mix of grease, paper and undersized yard drainage. See commercial drains.

25 October 2022 — The Night Ferny Creek Came Up
If you want one event that explains how water behaves in Upwey, it is this one. On Tuesday 25 October 2022, the border of Upwey and Tecoma reportedly recorded almost 94.6 millimetres of rain. A gauge off Glenfern Road was believed to have taken 133 millimetres. The Emerald SES unit received 34 calls for assistance across Upwey and Tecoma, with flooring, carpets and property damaged.
The unit controller, Ben Owen, described what happened in the creek line behind the township. The creek that runs in behind Upwey, Tecoma and Belgrave rose very quickly, he said, and inundated properties and houses. He described speaking to one homeowner who did not even have time to move their cars, and who ended up with water in the floor pan of all three of them. It was, in his words, just so fast and rapid.
The same night produced landslips. Emerald SES attended one at Upwey High School, which closed a footpath and blocked a school bus entry. Yarra Ranges Council recorded landslips at Belgrave Centre Road, Marchant Avenue and Blackwood Street in Upwey.
The line worth keeping is Owen's assessment of frequency. He called it a one-in-four-year flash flooding occurrence, and added that people generally think they are fine being in the hills, but when the water comes down that quickly the little creeks and streams simply cannot deal with it and it overflows into properties. A one-in-four-year event is not a rarity you can plan around. It is a normal part of owning a house here, and it is the reason a stormwater system in Upwey has to be genuinely clear rather than merely passable.
Two Creeks and a Catchment Name Nobody Uses
Upwey's water leaves the suburb through creek lines that start in the ranges above it. Ferny Creek rises in the Dandenong Ranges near Sherbrooke and runs down through Upwey, Upper Ferntree Gully, Ferntree Gully and Rowville. Mast Gully Creek is the other name locals know, and it is old enough to be the reason the district was called Mast Gully in the first place, after ship masts were cut from the gully back in 1850. Mast Gully Road still carries the name.
Downstream, Ferny Creek combines with another hills creek at Rowville, and the combined waterway becomes Corhanwarrabul Creek, which later becomes Dandenong Creek at Police Road. Almost nobody in Upwey uses the word Corhanwarrabul, but it is the formal name of the catchment your roof water is joining, and it sits inside the much larger Dandenong Creek catchment that eventually reaches Port Phillip at Patterson Lakes.
Two local details make the point better than the hydrology does. Upwey has a public reserve known locally as the Hume Street Drainage Reserve, and also as Ferny Creek Reserve. A suburb does not name a reserve after drainage by accident. And the Glenfern Valley Bushlands, forty hectares bounded by Glenfern Road to the south, New Road to the west, Ferny Creek to the north and Depot Track to the east, is described as land that falls gently from south to north. That is a precise, checkable statement of which way Upwey drains.
South East Water is also a formal partner, alongside Melbourne Water, the state department, the University of Melbourne and Yarra Ranges Council, in a smart water network project in this catchment that explicitly involves residents in surrounding suburbs including Upwey. So the public half of the system here is being measured and improved. The private half, between your roof and the street, is the half nobody is upgrading on your behalf.
Ridge Road, Valley Highway: Why Every Upwey Block Is on a Fall
Upwey has a simple road skeleton and it explains a great deal about the drainage. Burwood Highway and Glenfern Road are the two main roads through the suburb, connected by Morris Road, and Glenfern Road runs along the ridge of the hill. So you have a highway low and a ridge road high, and effectively every property between them is on a slope, draining one way or the other.
That has four practical consequences we see over and over.
🛣️ Burwood Highway is not council
It is a state arterial, so drainage in that road reserve is not a Yarra Ranges asset. If your problem sits in the highway itself, the council switchboard is not the right first call, and knowing that saves a wasted afternoon.
⛰️ Fall is a mixed blessing
Steep pipe self-cleans while water is moving, but the moment it hits a flat section, a bend or a bellied length, everything it was carrying drops out at once. Hill blockages tend to be sudden rather than gradual.
🅿️ Cut-in driveways concentrate water
A driveway carved into a slope becomes a channel. Whatever grate sits at the bottom is doing far more work than its size suggests, and it is usually the first thing to surcharge in a downpour.
🚚 Access is part of the job
Narrow shoulders, tight turns and steep drives are normal here. We plan the approach before arriving so the jetter reaches the opening rather than being parked three houses away. See hydro jet cleaning.
Landslip is the other consequence, and Upwey has the evidence rather than the theory. Yarra Ranges applies Erosion Management Overlays across the Dandenongs, and in Upwey what that policy exists to prevent showed up as three named streets with slips in a single night. Saturated ground moves, and ground that moves takes rigid pipe with it. A drain that has never blocked in twenty years can start blocking every winter after one wet season, and the reason is usually mechanical rather than anything anyone put down it.
Ten-Acre Blocks, Weekenders and What Ended Up Underground
Upwey's housing did not arrive in one wave, which is exactly why its drainage is so mixed. In the mid-1890s part of the locality was cut into ten-acre blocks under the Scoresby village settlement scheme. In 1897 the three Tullidge sisters bought a homestead here, named it Upwey after the English village on the River Wey, and persuaded Victorian Railways to approve a stopping place near the house. The post office followed in 1911, Upwey Primary in 1934, the high school in 1945 and Upwey South Primary in 1964.
The population tells the story cleanly. There were 95 people at the 1911 census and 1,770 by 1947, a jump Victorian Places attributes partly to wartime evacuees from the city deciding to stay, with weekenders superseded by permanent residents. By 2001 it was 6,897, by 2011 it was 6,964, and the 2021 census recorded 6,818. Upwey has been essentially the same size for a quarter of a century.
What that means for a plumber is a suburb of long-lived drainage on old lot geometry. Ten-acre blocks subdivided over a century leave drain runs that go where the original fences went, not where a modern surveyor would put them. Holiday shacks replaced by permanent homes leave lines that were extended rather than rebuilt. And a static population means very little has been knocked down and started again. It is the opposite of an estate suburb, where everything underground is the same age and the same material laid the same year.
The suburb also carries administrative history that surprises people. Upwey was in the former Shire of Sherbrooke, and the shire offices themselves were here: the Burrinja cultural centre on Glenfern Road, opened in 2011, stands on the site of the old shire offices. Upwey was the seat, not the outpost.
Frequently Asked Questions — Upwey
Plumbers and Blocked Drains in Suburbs Near Upwey
Tecoma sits immediately uphill and shared the October 2022 event with Upwey almost street for street. Belgrave is higher again and on a different sewerage arrangement worth understanding separately. Ferny Creek shares the creek name and the descent, and Ferntree Gully and The Basin are where the same water reaches flatter ground. Boronia, Knoxfield and Rowville are further down the same catchment again.
