Rotork flow control equipment has been installed throughout a major water industry AMP5 environmental improvement project at a sewage treatment works serving Somerset’s largest tourist resort on the south-western coast of England.Wessex Water has invested GBP 26M at the site to achieve improved bathing water quality for the resort of Weston-super-Mare. The improvements will ensure that the site can cope with increased population and continues to comply with standards set by the Environment Agency. The work has been completed ahead of the revised Bathing Water Directive, which comes into force in 2015 and introduces more stringent water quality standards.Rotork’s scope of supply for flow control in the project includes IQ multi-turn and IQT quarter-turn intelligent electric actuators, and IB manual gearboxes for motorised and hand operated valves and penstocks throughout the new works. All electric actuators are Profibus-DP V1 network enabled and centrally controlled by a bespoke SCADA system designed by the Wessex Water Automation Team. The use of Profibus technology, a standard feature of Wessex Water’s automation programmes, delivers significant savings in cabling, terminations, PLC hardware and labour. The SCADA system runs the automated processes and collects control, status and diagnostic data from each actuator. The upgrade project at Weston-super-Mare STW has been performed by a partnership made up of the Halcrow Group, Dean & Dyball Civil Engineering, Nomenca and Wessex Engineering & Construction Services. The Rotork equipment was supplied in accordance with the Framework Agreement that the company holds with Wessex Water.
