Council investigates spill at Robertson STP

28 January, 2016

Wingecarribee Shire Council will today continue investigations into a chemical spill which occurred yesterday at its Robertson Sewage Treatment Plant (STP).

The spill was identified at approximately 10.50am on Wednesday 27 January as part of routine inspections of the plant.

An estimated 3,500 litres of caustic soda was spilt from the plant.

Initial investigations suggest the chemical, which is used in the treatment of sewage, escaped as a result of a broken pipe carrying the chemical from an onsite storage tank.

Safety precautions ensured the chemical was contained on adjoining Council land.

Council immediately notified the relevant agencies including the Environmental Protection Authority (EPA), WaterNSW, SafeWork NSW and NSW Fire and Rescue.

Hazmat crews from NSW Fire and Rescue have since worked with Council staff to capture, contain, dilute and remove the spilt chemical.

Initial tests by NSW Fire and Rescue suggest the spill has been contained.  Further soil and water tests will be undertaken to ensure the spill has been controlled and neutralised.

As a precaution immediate neighbours were informed of the incident.  At no time was there any risk to residents.

Council thanks both NSW Fire and Rescue for their assistance and immediate residents for their understanding.

Further investigations will continue into the cause of the spill.

The Sewage Treatment Plant continues to operate without interruption.
