A sewer line broke Thursday night around 21st Ave. South in North Myrtle Beach.
Due to the break, a couple of hundred gallons of sewage ented a storm water drain.
An Ocean Outfall system is located at 21st Ave. South, causing the water to be dispered through an underground storm water pipe about a quarter-mile offshore. Use of the system kept the sewage away from ocean water.
The South Carolina Department of Health & Environmental Control (DHEC) has alerted swimmers they are not to swim within 500 feet on either side of 21st Ave. South until tests were conducted for the ocean water in question.
