Friday night phone call. Sewer line at a multi-unit apartment building had failed, residents had no functioning sewer, and it needed to be fixed before the weekend was over. We mobilized at 4 AM Saturday morning, located the failed section, dug it up, made the repair, and backfilled — all in a single shift. Every unit had working sewer again before the day was out. Most of our work isn't emergency work, but when a job has to happen right now, we show up.
