We were involved in a major contract to prepare the SCADA systems-part of the Water and Environmental Monitoring Network in Tai Lake region in eastern China in procurement, installation, testing and operation. The key SCADA equipment and software was supplied from Australia. Key challenges of the project were the integration of the new systems with the existing systems through database engineering and computer networking. As part of project delivery, we provided system design and documentation of the water and environmental monitoring systems, specification and procurement ofequipment and software including water and environmental monitoring sensors, installation, testing and commissioning of the systems. Based on the results obtained from the monitoring network, we provided an overall model and prediction of water quality changes in the Lake Tai region.
