ROVVER, QUICKVIEW HELP TROUBLESHOOT SANITARY SYSTEM OVERFLOW.
Las Vegas, Nevada – Responding to a sanitary system overflow (SSO) near the Las Vegas strip, crew from the Clark County, Nevada Department of Public Works encounter a 15” main filled with enough debris to halt their larger, non-steerable crawler after just a few feet. Jetting fails to clear the debris or improve crawling distance.
Already in the area, an Envirosight sales partner arrives on the scene with a ROVVER 600 and QuickView. Outfitted with large wheels and extenders, the ROVVER 600 pushes through the debris field before encountering a wall of debris at 185’, with debris levels steadily increasing thereafter.
The director of Public Works calls in an emergency excavation crew, who cut a 25’ x 50’ trench 25’ deep. With an 8” bypass installed and a 6” square opening cut into the exposed line, the QuickView is inserted to perform for a preliminary assessment revealing additional blockage.
Widening the opening makes room to lower the ROVVER 600, which finds a steadily tapered stream of concrete downstream, and total concrete blockage upstream.
A construction crew in the adjacent lot is drilling for caissons with a 50” auger. In conversation, the Department of Public Works crew learns they poured 40 yards of concrete into a subterranean footing the evening prior, only to lose 24.
Preliminary findings indicated that an auger had breached a lateral, pushing a massive amount of debris into the sanitary line followed by approximately 24 yards of hot-mix concrete, plugging the main for about 20’.
Thanks to Clark County’s focused response, the source of the SSO was identified quickly so that corrective measures could be taken.
