Mullumbimby’s drinking water will be sourced from the Rous County Council mains supply, rather than the Lavertys Gap weir for at least the next year, possibly much longer, owing to concerns about Mullum’s ageing water treatment plant.

Since the 1940s Mullumbimby’s water supply has come from a concrete weir on Wilsons Creek, at Lavertys Gap, piped by gravity through a treatment plant perched beside Wilsons Creek Road, to two concrete balancing reservoirs above the old Mullumbimby hospital on Azalea Street.
