Project Name: NCIG – Newcastle Coal Infrastructure Group
Vessel Type/Volume: Hydrochoc 20,000L Bladder Surge Vessel
The NCIG Project has a 20,000L Vertical Bladder Surge Vessel  installed for the Raw water supply to site.
This Vessel has been designed and manufactured to AS1210. This was manufactured by Charlatte Reservoirs S.A.S.

Project Name: Malabar Waste Water Treatment Plant Recycled Effluent Pump Station
Vessel Type/Volume: 3 x 6,000L Waste Water Bladder Surge Vessels
The MALABR WWTP has 3 x 6,000L Waste Water Vertical Bladder Surge Vessels for the protection on the Malabar waste water network.
These bladder surge vessels were designed and manufactured to AS1210. This project was installed and commissioned in 2015.


A Bladder Surge Vessel is a surge control device installed with an Internal Rubber Bladder. The bladder vessel is pre-charged with air to give the required stored energy volume to push water into the network during a surge transient.

The main advantages of Bladder Surge Vessels are there is no need for complicated controls and/or compressor systems. There is absolutely no dissolution of the air into the water and thus no requirement for a permanent regulation system. Once the vessel is commissioned with the modelled pre-charge the vessel will operate automatically, emptying and refilling during a surge transient.

In addition to this, if the vessel is fitted with the recommended level monitoring controls the surge vessel can be monitored on the local SCADA PLC and eliminate the need of regular maintenance. Please contact us for more information on this.

In Australia, we have bladder surge vessels ranging from 100L to 125,000L all which are commissioned and operating. We have bladder surge vessels in NSW and on major projects around Australia including the Victorian Desalination Plant which has 11 x 125,000L Bladder Surge Vessels. These are the largest bladder vessels ever commissioned.
