The San Antonio Water System says there won't be any disruption of service after a fire near a SAWS facility on Monday night. Fire officials say lightning started a grass fire near an oil tank not far from the H2Oaks desalination plant. Emergency crews responded about 9 p.m. to the blaze on Hardy Road east of I-37 and south of Loop 1604 on the South Side. A local power outage resulted from the lightning strike, but no injuries were reported.
