Can You Use Bore Water for High Pressure Washing in ACT?
Yes, bore water can be suitable for high pressure washing in Canberra, provided the supply is lawfully accessed, the water quality suits the equipment and surface, and washwater is managed responsibly. Bore water is not automatically clean or suitable just because it looks clear.
Before cleaning a driveway, patio or commercial hardstand, check three things: your bore’s approval conditions, the water’s mineral and sediment content, and where the cleaning runoff will go.
Check ACT Bore Water Requirements First
Groundwater use in the ACT is regulated under the Water Resources Act 2007. Requirements depend on the bore, the purpose of extraction and any applicable exemptions or approval conditions. Having a bore on your property does not necessarily mean you can use unlimited groundwater for any purpose.
Before using it for pressure washing, confirm that extraction and the intended use are permitted under the relevant licence or entitlement. Check with the ACT Government’s water resources team if you are unsure, particularly when engaging a commercial cleaning contractor.
Do not assume rules for mains drinking water apply identically to bore water. In 2026, check current ACT water restrictions and your groundwater conditions separately before starting work.
How Bore Water Can Affect Cleaning Results
Iron, manganese and mineral deposits
Some groundwater contains iron or manganese that can leave orange-brown or dark staining. Dissolved salts and hardness minerals may also leave residue as the surface dries. This is especially noticeable on pale concrete, pavers, glass and painted finishes.
A small test patch helps identify immediate staining, but allow it to dry before judging the result. Where mineral levels are high, another water https://kameronbrlk177.rivetgarden.com/posts/canberra-end-of-lease-cleaning-exterior-tasks-explained source may provide a better finish.
Sediment and equipment damage
Sand and grit can clog nozzles and damage pressure washer components. Use filtration that meets the equipment manufacturer’s requirements, and confirm the bore system delivers sufficient inlet flow and pressure.
An ordinary sediment filter does not remove dissolved salts, hardness or all microorganisms. Water treatment needs to match the actual problem.
Practical Checks Before Pressure Washing
- Assess water quality: Consider laboratory testing for sediment, iron, manganese, hardness and salinity. Seek advice about microbial testing if contamination is possible.
- Check equipment specifications: Confirm acceptable inlet water quality, temperature, flow and pressure.
- Protect drinking water: Do not directly connect bore plumbing to the mains supply. Ask a licensed plumber about separation and backflow protection.
- Reduce exposure: Keep people and pets away from spray. Untreated bore water may contain microorganisms, and pressure washing creates aerosols.
- Test the surface: Use an inconspicuous area and suitable pressure to avoid etching concrete or damaging joints and coatings.
Keep Contaminated Washwater Out of Stormwater
Using bore water does not remove your responsibility to manage runoff. Pressure cleaning can pick up oil, detergent, sediment, paint flakes and other pollutants. Keep contaminated washwater out of street gutters and stormwater drains, which discharge into local waterways.
Sweep up loose material first, protect nearby drains and use containment or recovery equipment where needed. Arrange an appropriate disposal method; do not assume discharge to the garden or sewer is acceptable.
Is Bore Water the Best Choice?
Bore water can be a practical option for high pressure washing in the ACT when permissions, water quality and runoff controls are addressed. Tell your Canberra pressure cleaning provider about the bore supply before booking so they can assess filtration, equipment compatibility and whether an alternative water source is preferable.
