Water sources across the Central Coast NSW

Central Coast Council supply

Mangrove Creek Dam and the Mardi-Mangrove system supply the majority. Historically stable, with wet-season turbidity managed at the plant.

Rainwater tanks

Dominant on the Mangrove Mountain plateau and rural-residential blocks. Coastal aerosols nudge conductivity up on beach-adjacent tanks.

Plateau bore

Mangrove Mountain and Somersby plateau bores tap Hawkesbury sandstone — expect iron staining and occasional hardness.

Farm dams

Stock, irrigation and emergency backup on the plateau. Basic Water Safety Check for human-contact use.

Bathurst & Central Tablelands water testing

Cold-climate high country west of the Blue Mountains: granite-belt bores around Bathurst, rich basalt soils and orchard bores under Mount Canobolas, Fish River scheme towns, and frost-country rainwater tanks that sit for months between refills.

Northern Rivers water testing

NSW's wettest coastal corner: high-rainfall roof-catchment tanks on the hinterland, acid-sulfate-affected shallow bores on the floodplain, and post-2022-flood contamination that still shows up in test panels today.

Riverina & Southern Tablelands water testing

Big country, big contrasts: Murrumbidgee irrigation-area bores that can push nitrate and salinity, Southern Tablelands rainwater tanks and basalt bores, and blue-green algae watch across the summer river systems.

Tweed / Byron Border Coast water testing

Border-coast franchise territory spanning the Tweed and Byron catchments — from Tweed Heads and Kingscliff south to Byron Bay and Mullumbimby. Mail-out kits and local sample handling.
