Testing to look for leaks in the City’s sewer system began this week in Richardson (see map). The testing, conducted by the RJN Group, will involve the use of smoke to identify where storm water may be entering underground sewer lines. The smoke is nontoxic, with minimal odor, but it could be very visible in areas where leaks are detected.
Testing continues next week, weather permitting. Testing on specific streets within the study area should only take 20-30 minutes. If you live in the test area, you will see a notice placed on your front door at least 24 hours prior to the test. Street signs will also be placed at each end of the blocks where testing is underway. Smoke testing cannot be conducted if it is raining or has recently rained. If crews are unable to conduct testing in the notified areas due to weather, the areas will be re-notified before testing is conducted at a later date.
This is the fourth year of a multi-year schedule for smoke testing of the City’s 410 miles of sewer lines. Over the last three summers, 245 miles have been tested; 5.3 miles will be tested this summer.
