A water line break under a Delta townhouse driveway.
Water was coming up through the asphalt in a townhouse complex. We located the break, dug a small trench, replaced the damaged section of 2-inch water line, tested it and filled the hole back in.
Water was coming up through the asphalt.
The strata called about water running across the driveway in front of one of the units. The leak was underground, so the first step was to find which shutoffs controlled that area and how many homes they served.
One valve controlled six units. Before digging, we planned a temporary water supply from the unit next door so those homes kept water while the line was off, and booked a BC One Call so other buried utilities were marked.
A small trench, right over the break.
We cut out the asphalt and dug a trench about 8 feet long, 3 feet wide and 3 feet deep, down to the line. The leak was a hole in the 2-inch polyethylene (PE) water line.
The damaged piece was cut out and a new section installed, with concrete thrust blocks to hold the fittings in place. We turned the water back on, pressurized the line and checked it: no leaks. Then the pipe was bedded in sand, rocks were cleared away from it, and the trench was backfilled to the original grade.
Find it, dig small, fix it, test it.
We planned the dig before we broke the asphalt, so the job stayed as small as the leak.
Find the shutoffs
Work out which valve controls the leaking section and which homes it serves.Plan the dig
Mark the area, call BC One Call, and set up temporary water for the affected units.Repair the line
Cut out the damaged pipe, install a new section and add thrust blocks.Test and backfill
Pressurize, check for leaks, bed the pipe in sand and fill the trench back in.The line holds pressure and the driveway is filled in.
The leak was a single hole in the water line. Digging in one spot fixed it without opening up the rest of the driveway. Repaving the asphalt was left to the strata, as agreed before the work started.
