Water quality across New South Wales

New South Wales has a diverse water supply network, from Sydney’s major catchments to regional systems across the state.

Chlorine treatment, naturally occurring minerals, and water hardness can all influence how water tastes, smells, and behaves around the home, while PFAS remains an area of ongoing monitoring. 

For NSW families, these water characteristics can shape what you need from a whole home filtration system.

  • Sydney

    Sydney's water comes mainly from Warragamba Dam, and some suburbs receive chloramine-treated water that can noticeably affect taste and odour. Explore whole home filtration in Sydney.

  • Newcastle

    Newcastle's dams and sandbeds supply the Lower Hunter, and seasonal algae in reservoirs can occasionally cause earthy or musty tastes. Explore whole home filtration in Newcastle.

  • Central Coast

    Central Coast water comes from creeks, dams, and groundwater, and heavy rain can stir up sediment that affects clarity. Explore whole home filtration on the Central Coast.

  • Wollongong

    Wollongong's water is treated at the Illawarra Water Filtration Plant, and homeowners often want filtered water beyond the kitchen tap. Explore whole home filtration in Wollongong.

Sydney water quality

Sydney’s water comes from a large network of catchments and reservoirs, so its characteristics can vary as different sources are used across the wider supply network. Chlorine can be noticeable in household water, while some areas may also experience metallic tastes or odours and other changes in how their water looks, tastes or smells.

Newcastle water quality

Newcastle’s water can vary in taste and odour depending on local conditions and the substances present in the supply. Some households may notice earthy or musty characteristics, while chlorine and other treatment-related tastes can also affect the taste and smell of water at the tap throughout the local water supply. PFAS is also a well-known local concern, and many Hunter households are looking for better filtration for their drinking water.

Central Coast water quality

Central Coast water can contain naturally occurring minerals such as iron and manganese, which may affect its taste, appearance and colour. These characteristics can become more noticeable in certain seasons, with local water conditions contributing to differences in how water looks, tastes and smells between areas.

Wollongong water quality

Wollongong’s water comes from the Illawarra’s local catchments, where water is treated before reaching homes. While hardness is generally lower across the region, households can still notice changes in taste and smell, including effects associated with treatment and naturally occurring characteristics of the local water supply.
