TEMPORARY WATER PIPE

THE 8" OLD WATER PIPE IS THE LAST WATER PIPE TO BE CONNECTED TO THE BLACK TEMPORARY WATER PIPE SO THE OLD WATER PIPES MOUNTED ON THE SIDE OF THE BRIDGE CAN BE REMOVED.

THE CREW PREPARES THE SITE TO OPEN A TRENCH TO CONNECT THE 8" WATER PIPE..

AN AIR RELEASE VALVE IS INSTALLED ON THE TEMPORARY WATER PIPE..

THE 8" OLD WATER PIPE IS ISOLATED ON BOTH SIDES OF THE BRIDGE..

THE CREW BEGINS BY TO SCRAPEING AWAY THE DIRT TO EXPOSE THE 8" WATER PIPE..

THE 8" OLD WATER PIPE FROM THE ISOLATION VALVE IS UNCOVERED..

GRAVEL IS DUMPED INTO THE PIT TO ABSORB THE WATER AND ALLOW IT TO BE PUMPED FROM THE PIT WHILE THE CREW IS WORKING..

THE 8" WATER PIPE IS CUT OPEN TO DRAIN THE WATER..

WHEN THE WATER IS DRAINED, THE PIPE IS CUT THROUGH..

THE INDIVIDUAL PIECES ARE CUT TO ALLOW THE SPLICE TO BE INSTALLED..

ALL OF THE COMPONENTS ARE WASHED WITH CLOROX AND WATER..

THE FIRST PIPE IS BOLTED IN PLACE IN THE BYPASS VALVE..

THEN THE FITTING FOR THE SECOND PIPE IS BOLTED IN PLACE..

THE SECOND PIPE IS INSTALLED AND BOLTED IN PLACE..

THEN THE LAST PIPE IS BOLTED IN PLACE TO COMPLETE THE BYPASS ON THE NORTH SIDE OF THE BRIDGE..

THE CREW THEN MOVES TO THE SOUTH SIDE OF THE BRIDGE AND DOES  IT ALL OVER AGAIN..
