100,000-Gallon Sewer Spill Hits East San Antonio
- San Antonio Water System crews responded after a 24-inch sewer main collapsed near Bicentennial Road and I-10 East, sending more than 100,000 gallons toward Rosillo Creek. (saws.org) - The break was tied to recent heavy rains. SAWS set a temporary bypass, started repairs, and warned people to avoid creek water. (saws.org) - It matters because sewer overflows still happen despite years of upgrades under San Antonio’s long-running EPA cleanup program. (saws.org)
A sewer main collapse on San Antonio’s East Side turned into a big wastewater spill this week — the kind of infrastructure story that matters fast because it can hit creeks, neighborh(saws.org)st, and SAWS says the spill topped 100,000 gallons. The immediate problem is obvious: untreated sewage got out before it could reac(saws.org)nd are still repairing the damaged line. (saws.org)ve, east of I-10, near Rosillo Creek. That location matters because once wastewater escapes in a low area near a creek, it does not just stay in one hole in the ground — it can move with runoff and standing water.

That is not a house connection or a tiny neighborhood pipe — it is a major wastewater line, big enough that a structural failure can release a huge volume before crews can isolate it. (saws.org) ### Why did it happen now? The utility says recent heavy rains inundated the line and weakened the structure. Basically, the pipe was overwhelmed in a bad spot, and the surrounding conditions helped turn a weak point into a collapse. KENS reported workers and nearby businesses noticed the smell and then found a sinkhole tied to the break. (saws.org) ### Did it reach the creek? SAWS and local coverage both point to Rosillo Creek as the area potentially affected, and KENS said more than 100,000 gallons were released into the creek area.

(ksat.com) ### Is this unusual for San Antonio? Yes and no. A 100,000-gallon spill is serious, but SAWS has spent years trying to push sewer over(saws.org)EPA consent decree, and it also said 2024 ended with 132 overflows — a record low for the system, down 75% over 15 years. So the trend has improved, but this spill is a reminder that aging pipes and heavy rain can still beat the system in isolated spots.

The repair work should limit further damage, but the bigger takeaway is that storm stress and old infrastructure are still a live risk even after years of upgrades. (saws.org)
