Pumping water from our rivers
Council pumps water from the Hastings River at Koree Island (5km south-west of Wauchope), which is approximately 2 kilometres upstream of the tidal limit on the river.
Pumping from the river can only be undertaken when a number of strict conditions are met:
Nutrient levels - nutrients in storage dams can lead to the growth of algae which affects water quality. Nutrient levels are often high after rainfall events due to runoff, and pumping must cease in these instances.
Turbidity - turbidity is a measure of suspended particles in the water. Turbidity can impede the disinfection process allowing the growth of pathogens which can cause illness.
River flow - extraction is dependent on river levels to maintain the natural environment. When flows fall below the monthly environmental flow target, pumping must cease to protect aquatic species such as fish, platypus and plants.
These conditions are monitored to ensure extraction is only undertaken within the permissable limits.
When no pumping is undertaken, consumers are then supplied from either the Port Macquarie or Cowarra storage dams.
Water pumping stations
The Koree Island pumping stations have a combined capacity to pump 120 megalitres (ML) per day into the Rosewood Reservoirs and on to the Port Macquarie and Cowarra Off-Creek storage dams.
The villages of Comboyne, Long Flat and Telegraph Point have their own water supplies which are pumped directly from the Thone, Hastings and Wilson Rivers respectively. They all have small reservoirs and need to pump water more often to keep them topped up on a daily basis. Micro-filtration water treatment plants at the villages allows Council to pump water even when it is raining and the river water is turbid. These automated facilities are continuously monitored and controlled remotely by Council and are regularly maintained by Council operational staff.
