    49. 49. Recovery and reuse of wastewater – need to be sure you know what&apos;s in it!<br />
    50. 50. So what&apos;s my take home message about water at Cranfield?<br />International leading research on sustainability is in water resources, energy and chemicals. <br />Research is focussed on short and long terms solutions to municipal, industrial and agricultural needs.<br />Run UK’s largest Water MSc programme producing 120 new graduates per year. <br />
