The system is made up of a range of components which include:
Coonemia Bulk Storage Pond
The bulk storage pond has a capacity of 600 megalitres (ML) which is around 12,000 average swimming pools or 600 Olympic swimming pools.
Bulk Storage Return Pump Station
The bulk storage return pump draws reclaimed water from the pond to supply the distribution system.
Coonemia Distribution Storage Reservoir
The distribution storage reservoir holds 4ML, it balances the flows pumped from treatment plants to end-users and maintains constant water pressure in the distribution system.
The treatment plants included in the Scheme are: Vincentia, Culburra Beach, Callala, St Georges Basin, Vincentia, and more recently Nowra and Bomaderry.
There are over 29km of pipelines that connect the treatment plants to end-users including a network of dairy farms on the Shoalhaven floodplain east of Nowra. There is also a 1,400m pipeline constructed under the Shoalhaven River .
Farm Ponds & Flow Control Works
Each property connected to the scheme has their own storage pond which holds approximately one day’s irrigation. A flow control valves automates the rate of supply to each bulk user.
