Piangil Pump Station – Rural customers in surrounding area including Manangatang township
Last update
Starting: 10 am, 12 December 2025
Reason: Blue-Green Algae
AMBER ALERT
Laboratory testing of water samples continues to indicate that blue-green algae levels have increased at the Piangil Pump Station, which pumps from the Murray River.
Water delivered by the Piangil Pump Station is still safe to use and is below the blue-green algae limit recommended for recreation purposes.
Manangatang township customers
This Amber Alert does not affect Manangatang’s water quality and customers may continue to use Manangatang’s water for drinking, food preparation, ice making and other human consumptive purposes.
We ask Manangatang customers to minimise water use outside the home until further notice. This also applies to outside watering at the school, hospital and recreation reserves where mains water is used.
Rural customers
Rural stock and domestic customers will continue to be supplied from the Piangil Pump Station. We strongly recommend rural customers fill all on-farm tanks now in anticipation of a status Red Alert being issued.
Customers are reminded that your rural water supply is not safe for drinking. Water can be used for household activities, such as watering gardens, flushing toilets, showering/bathing, irrigation and laundry.
We will send an SMS to customers on the Piangil Pump Station system, who have provided us with their mobile phone details, when water quality results indicate a change of alert in our three step blue-green algae scale listed below.

The catchment covers an area of about 140 km2 and acts as a sub-catchment for the Rocklands Reservoir catchment. Moora Moora can also receive water directly from the upper Glenelg River via transfers along the Moora Inlet Channel.
Recreationally, Moora Moora is especially popular for bush camping, fishing and boating.
