This structure was designed by a Faculty of Queen's University Belfast so the drainage water from the developed land of Craigavon could be controlled in two lakes before final discharge by normal watercourses to Lough Neagh. When the construction was complete it was estimated that it would take 3 years for the lakes to be full and the syphon system working as designed. However rainfall has no timetable to suit man's designs and the lakes completely filled over their first winter in existence and the drainage from the developed land has worked very well since it was installed.
