THE MATERIAL IS READY TO BE INSTALLED..

EVERYTHING AND EVERY BODY ARE IN PLACE..

IT'S 11:00 PM AND THE WATER IS SHUT DOWN ON THE 6" WATER PIPE..

AND THE DIGGING BEGINS..

AFTER THE SURFACE DIRT IS REMOVED, THE REST IS HAND DUG..

THE 6" AC EXISTING WATER PIPE, THAT WAS INSTALLED IN 1956, IS EXPOSED..

A SUBMERSABLE PUMP IS COVERED IN GRAVEL TO COLLECT THE WATER WHEN THE PIPE IS CUT OPEN..

A CIRCLE CUT CHAIN WRENCH IS PREPARED FOR CUTTING THE AC PIPE..

A COUNTY WATER DEPARTMENT EMPLOYEE INSTRUCTS THE WORKER ON THE USE OF THE CHAIN WRENCH CUTTING TOOL..

THE HYMAX COUPLINGS ARE SLIPPED OVER THE AC WATER PIPE AND BOLTED IN PLACE..

THE BLUE FLUSHING WATER PIPE IS INSERTED INTO THE TWO SADDLE TAPS..

WITH THE NEW ISOLATION VALVE CLOSED, THE SOUTH FLUSHING PIPE IS OPENED TO FLUSH THE PIPE OF AIR AND ANY DEBRI THAT MIGHT HAVE GOTTEN IN DURING CUTTING..

THE WATER PRESSURE IS SLOWLY INCREASED TO PREVENT DAMAGE TO THE WATER PIPES..

AFTER THE SOUTH SIDE IS FLUSHED, THE NORTH SIDE IS FLUSHED..

AS THE FLUSHING NEARS AN END, THE DIGGING CREW STARTS TO BACK FILL THE DITCH..
