What a garden bore actually is
About one in four Perth household gardens runs off a private garden bore drawing on the shallow Superficial aquifer. That is a lot of Gosnells properties, particularly on the older townsite blocks where the lots are generous and a bore has always made sense for the reticulation.
That water has not been through a treatment plant. It comes out of the ground carrying whatever the ground has in it — iron, sediment, minerals, and a lot of local variation. Two bores on the same street can deliver noticeably different water.
Your scheme water is a different supply entirely. Gosnells is fed by Perth's Integrated Water Supply Scheme, a blend of roughly 44.6% groundwater, 36% desalinated seawater and 18.7% surface water, which is treated before it reaches you. The bore and the scheme are two separate systems arriving at the same property, and they stay separate.
What untreated groundwater does
The complaints are consistent and they are rarely about drinking.
Iron staining
The orange-brown marks on paving, limestone, fences and rendered walls. Iron comes out of the ground dissolved and clear, then oxidises in air and stains what it lands on. That is why the water looks fine out of the sprinkler and the paving does not.
Blocked and failing sprinklers
Sediment and iron deposits build up in solenoids, nozzles and small orifices. Heads that stop rotating, zones that lose pressure, and a reticulation controller blamed for something that is not electrical.
Deposits in fittings and lines
Anything with a narrow passage in it accumulates first.
Wear on the pump
Grit through a pump does what grit through any pump does.
Smell
Some bores have a distinct sulphur character that comes and goes with the season.
If any of that is what you are dealing with, ring and describe it. What is coming out of your particular bore decides the equipment, so this is a look-first job rather than a catalogue one.
Why it stays separate from your drinking water
This is the part worth being clear about.
Bore water is for the garden and the reticulation. It is not connected to the household drinking supply, and the two systems have to stay physically separated so that nothing from the bore can find its way into the scheme water in your house or the mains in the street. That separation is not a preference. It is how the plumbing is required to be done, and it is a large part of why bore work belongs with a licensed plumber rather than with whoever is available.
So if your question is about the water in your kitchen, this is not the page — that is scheme water and a different system. Under-sink drinking water filters · Whole house filtration
And if your question is about both, that is two jobs on one property, which is common and perfectly normal. We quote them separately so you can see what each one is for.
What treating a bore involves
The equipment sits between the bore and whatever you are protecting, and it is chosen around what the bore is delivering.
Broadly, the parts of the problem are separable. Suspended sediment and grit are physical and are dealt with physically. Dissolved iron is chemical — it has to be brought out of solution before anything can catch it, which is why a plain sediment filter on an iron bore disappoints people. Smell is its own conversation again.
That is the honest reason we will not quote a bore system over the phone. The right arrangement for a bore with sediment and no iron is not the right arrangement for a bore with iron and no sediment, and installing the wrong one costs you money and changes nothing.
Access and siting matter as well. The equipment needs to be near the bore head or the pump, under cover where possible, mounted properly, and reachable for servicing — because bore filtration is not a fit-and-forget installation. Untreated groundwater loads a filter far faster than treated scheme water does.
Gosnells specifically
The suburb divides into two here, as it does with most plumbing.
The old townsite
— the 1960s and 70s streets off Albany Highway and around the two stations — has the generous blocks, the established gardens and the long-standing bores. Plenty of those bores and pumps have been there for decades, and the reticulation they feed has been extended and patched more than once. A treatment system going onto that is fitted to what is actually there.
The newer estates and infill
are a different picture. Smaller lots, newer reticulation, and often a bore that was put in with the house. Less accumulated history to work around, and a tighter spot to put anything.
Semi-rural properties
on the eastern edge of the district lean harder on bore water than anyone on a standard suburban block does, and the consequences of untreated water show up faster there.
Servicing afterwards
A bore filter needs its consumables changed more often than a kitchen one. That is not a defect — it is what happens when you ask a cartridge to handle untreated groundwater instead of treated mains water.
We do those changes, and we will tell you honestly at install time roughly what sort of interval your bore is going to demand, rather than quoting a household figure that is going to be wrong. Cartridge replacement
Getting a price
Ring or send the form and describe what the bore is doing — the staining, the sprinklers, the smell, whatever it is. A licensed plumber comes out at no charge, looks at the bore, the pump and the lines, and gives you a written price before anything starts.
