Smoke Testing in the Portola Highlands and Crestmoor Neighborhoods

The City of San Bruno has engaged Duke’s Root Control, Inc. to perform smoke testing in the Portola Highlands and Crestmoor neighborhoods as part of the Earl Ave. / Glenview Ave. Sewer Main Improvement & Replacement Project. The purpose of the testing is to detect defects in the underground sewer system by introducing non-toxic smoke into the pipes and observing where the smoke escapes, which indicates issues such as cracks, improper connections, or open cleanouts. The contractor will carefully document all observed smoke exits to pinpoint locations requiring repair or maintenance, ensuring the integrity and efficiency of the sewer infrastructure. This activity is scheduled under a forecasted project posted on August 7, 2025, with no solicitation number or set-aside details provided. All work will take place within California, specifically in the targeted neighborhoods of San Bruno. The primary point of contact for inquiries is Calvin Iwan, Assistant Engineer, who can be reached via phone at 650-616-7065 or email at ciwan@sanbruno.ca.gov. The testing is a critical step in the larger infrastructure improvement initiative and is designed to support long-term system reliability without disrupting regular residential activities.
