DC Water Performs Dye Test to Confirm Sewer Leak

In a remote area of Soapstone Creek, beyond the Soapstone Valley trail, there was a slow leak detected in a sewer pipe. It almost went unnoticed but through a series of tests which required the use of dye, the leak was detected and repaired. DC Water Dept. inspectors poured a concentrated green dye into a manhole upstream from the ooze site, and sure enough, green dye showed up in the ooze. That test identified the source as a particular sewer pipe east of Audubon Terrace and next to the forested Soapstone Valley Trail. The leak existed in an 18-inch diameter, 1908 terra cotta gravity-flow pipe. There is 7,000 linear ft. of pipeline throughout Soapstone Valley and the repairs involved approximately 296 linear feet of pipe in all The Cured in Place Inversion method was used and in 24 days, after close attention to detail, the leak was contained. However, the City is advising that residents stay away from the area as bacteria levels are being evaluated.
