River Extraction Update as at 9/11/2018

On 8 November 2018, Council recommenced river extraction and filling of Port Macquarie Dam.  This follows an extended period without any inflow due to the trunk main relocation associated with RMS works at Spencers Cutting Wauchope, and unsuitable water quality following rainfall in the catchment in the two weeks prior. 

Port Macquarie Dam continues to be filled from the river while environmental conditions allow.  Should river levels or water quality prevent river extraction, transfer from  Cowarra Dam to Port Macquarie Dam will be utilised.

Water Demand

In 2015/16 the average annual residential consumption of water was 157kl per property per annum.  This is a 3% decrease from 2014/15 figures. Residential consumption makes up 76% of total water consumption in the Hastings.

Further changes that continue to reduce the Hastings annual water consumption include increased awareness and implementation of water conservation measures, retrofitting existing houses with water efficient products, new BASIX houses and dual reticulation.
