Water in Gosford
Gosford mains water is supplied by Central Coast Council. The primary source is Mangrove Creek Dam in the hinterland, supplemented from Mardi Dam and the Hunter Water interconnect during dry years. The water is treated and chlorinated to meet the Australian Drinking Water Guidelines.
For most Gosford households the only complaint about the tap water is the chlorine taste. A two-stage under-sink filter (sediment + carbon) removes it for the kitchen drinking tap. A whole-house system removes it before it reaches every tap, the shower, and the washing machine.
Older homes — sediment and discolouration
Several established Gosford suburbs — East Gosford, Point Frederick, parts of North Gosford and Wyoming — have older houses with aging galvanised internal plumbing. The mains water arrives clean, but the pipework downstream of the meter can shed iron and sediment, especially after upstream maintenance or a water-main flush.
If you see occasional brown water at the tap, the answer is a sediment pre-filter — a 5 micron polypropylene cartridge ahead of the carbon stage catches the rust and grit before it reaches the kitchen. A whole-house Big Blue with sediment + carbon handles it for the whole property.
Rural properties west of the M1
Kariong, Somersby, and the rural blocks heading toward the Old Pacific Highway often draw drinking water from rainwater tanks. Tank water needs a different setup — sediment, carbon, and UV sterilisation — to bring it up to NSW Health's recommended standard for non-mains drinking water. See the rural tank water page for the full configuration.

Frequently asked questions
Where do I get the system from?
Standard delivery anywhere in Gosford — usually next business day from our Wyong warehouse. Or use Click & Collect from the showroom at 6/45 Amsterdam Cct, Wyong. The drive from Gosford is about 25 minutes up the M1; pickup orders are typically ready within two hours during business hours.
Is the water in Gosford chlorinated?
Yes. Central Coast Council chlorinates the mains supply, drawn primarily from Mangrove Creek Dam. Chloramine is not used on the Central Coast — that is a Sydney Water practice. A standard carbon filter handles chlorine taste; you do not need a catalytic carbon cartridge unless you are in a chloramine area.
I'm in an older Gosford home with discoloured water — what filter do I need?
Older suburbs around East Gosford, Point Frederick, and North Gosford often have aging galvanised house plumbing that sheds iron and sediment, especially after a water-main flush. A sediment pre-filter ahead of carbon is the right setup. A 10" twin under-sink or whole-house housing with a 5 micron sediment cartridge and a carbon block typically clears it.
I'm on a rural block near Kariong or Somersby — do I need something different?
Yes. Rural properties west of the M1 are often on tank water rather than mains. Rainwater needs the full sediment + carbon + UV setup — not because the water is dirty, but because tanks are open to airborne contamination and the standard NSW Health recommendation is a multi-barrier treatment train for any non-mains drinking supply.
Do you install systems, or just sell them?
We sell the systems and parts. Mains-pressure installs in NSW must be done by a licensed plumber by law, so we focus on getting the right system to you and can refer a Central Coast plumber who installs our systems regularly. Under-sink filters with push-fit fittings are usually a DIY job.
