"Safe" and "what you prefer to drink" aren't always the same thing. Adelaide water contains chloramine, fluoride at 0.6–1.1 mg/L, and NO detectable PFAS. None of these are a health emergency at typical levels, but many people filter them out anyway — for taste, personal preference, or health reasons.
Adelaide's water supply comes from 7 Mount Lofty Ranges reservoirs, the River Murray via two major pipelines, and the Adelaide Desalination Plant (up to 50% of supply during peak demand).
Primary catchment sources
About 40% of Adelaide's water comes from the Mount Lofty Ranges reservoirs — primarily Mount Bold (46.2 GL), Happy Valley, and Myponga. The remaining 60% comes from the River Murray via two major pipelines. This water is treated at 3 major water treatment plants across Adelaide: Happy Valley, Anstey Hill (for River Murray), and Myponga.
Desalination
The Adelaide Desalination Plant can produce 300 ML per day, providing up to 50% of Adelaide's peak demand. Seawater is desalinated and blended with reservoir and River Murray water. This gives Adelaide exceptional drought resilience.
Adelaide's water journey
From rainfall in protected catchments and River Murray flows to your kitchen tap — here's how Adelaide's water is collected, treated, and delivered.
Rain falls across the Mount Lofty Ranges catchments and flows into reservoirs. Additional water comes from the River Murray via the Mannum-Adelaide Pipeline (87 km) and Murray Bridge-Onkaparinga Pipeline (approximately 49 km).
Water flows into 7 key Mount Lofty Ranges reservoirs: Happy Valley, Mount Bold (46.2 GL), Myponga, Millbrook, Hope Valley, Little Para, and South Para. Total capacity ~200,000 ML. River Murray water arrives via pipelines.
Raw water moves through pipelines to 3 major treatment plants: Happy Valley Water Treatment Plant, Anstey Hill Water Treatment Plant (for River Murray water), and Myponga Water Treatment Plant.
Multi-barrier treatment: coagulation, flocculation, filtration, chloramine disinfection, Powder Activated Carbon (for algal taste/odour management), and fluoridation at 0.6–1.1 mg/L.
Treated water flows through 9,416 km of pipes and 10 metropolitan storage reservoirs, maintaining pressure and quality across metropolitan Adelaide and surrounding regions.
Clean drinking water arrives at your kitchen tap. For the best taste and to remove residual chloramine, PFAS, and microplastics — add a Tapp filter as the final step.
Here are the main parameters SA Water monitors and reports annually:
Note on chloramine vs. chlorine: Adelaide uses chloramine (chlorine bound to ammonia) for disinfection, not free chlorine. This is gentler but lasts longer in the distribution system. It's why many people report chlorine taste/smell — it's actually chloramine.
PFAS (per- and polyfluoroalkyl substances) are "forever chemicals" used in non-stick coatings, firefighting foams, and food packaging. They persist in water and bioaccumulate.
What's being done: SA Water is investing in advanced treatment technologies at all major facilities. Current multi-barrier treatment (coagulation, filtration, Powder Activated Carbon) is effective at preventing PFAS accumulation. The water continues to test compliant with NHMRC guidelines.
For personal filtering: Tappwater's EcoPro Compact and SMR tap filters remove 93% of PFAS via activated carbon nanofiltration. For maximum PFAS removal (99%), the RO Countertop uses reverse osmosis — the most effective consumer technology available.
Adelaide has moderately hard water (93–96 mg/L CaCO3). For reference:
- Moderately hard: 60–120 mg/L (Adelaide falls here)
- Moderately hard: 60–200 mg/L
- Hard: >200 mg/L (Perth: 200+, Adelaide: 150+)
Soft water is generally better for appliances (less scale buildup), but doesn't mean your water is "pure" — hardness just measures dissolved minerals like calcium and magnesium.
Adelaide's water is safe, but you might filter for taste, hardness/mineral reduction, chloramine/fluoride removal, or algal taste issues. It depends what you want to remove.
EcoPro Compact
5-stage nanofiltration. Removes chloramine, 93% PFAS, 70% fluoride, and >99% microplastics.
EcoPro Chrome SMR™
Same 5-stage filtration plus Swedish Mineral Rock™ — adds calcium, magnesium, and potassium.
RO Countertop
7-stage reverse osmosis. Removes virtually everything including fluoride, PFAS, lead, and heavy metals.
If Adelaide's water meets the guidelines already, why filter? Personal preference. Here's how to choose:
| Filter | Chlorine | Fluoride | PFAS | Microplastics | Price | Best for |
|---|---|---|---|---|---|---|
| EcoPro Compact | >97% | 70% | 93% | >99% | $109.99 | Best value |
| EcoPro Chrome SMR™ | >99% | 70% | 93% | >99% | $149.99 | Taste + minerals |
| RO Countertop | >99% | >99% | 99% | >99% | $799.99 | Maximum protection |
Use this table to compare what each Tappwater filter removes from Adelaide's water:
| Contaminant | In SA Water | Compact | SMR | RO Countertop |
|---|---|---|---|---|
| Chlorine | Chloramine-based | >97% | >99% | >99% |
| Fluoride | 0.6–1.1 mg/L | 70% | 70% | >99% |

| TDS reduction | ~160 mg/L | — | — | 85% |
| Best for Adelaide | — | Best value | Taste + minerals | Maximum protection |
Adelaide's water is safe. Filtered, it's better.
