The last manhole, which connects to the existing drain (on the left).  The drains are now ready for testing for leaks.  We will put a bungs in and fill each section with water.  When the whole system is full of water, it will be left for about hour to make sure the level doesn't drop (building control also visit to inspect this).  The bungs are then removed to check it all drains.
