Trident Health is set to invest about $24 million to upgrade its emergency care services in Summerville as the population continues to swell in and around Flowertown. 

Work is scheduled to begin Wednesday on the expansion project at Summerville Medical Center. It's expected to increase capacity, add about 13,000 square feet of space and enlarge the pharmacy and lab, among other improvements. 

The emergency department will remain open.

The expansion will help the Dorchester County hospital improve its pediatric program and increase the number of private patient rooms, said Dr. Preston Wendell, medical director of Trident Health's emergency rooms.

In all, the health system has budgeted $100 million in improvements for Summerville Medical Center, near where young families are moving in and where competing health providers are expanding.

The town of Summerville has slightly more than 50,000 residents, and the population has increased by 18 percent since 2010, according to the Census Bureau. It's also near several large housing developments, such as Nexton, Cane Bay and Carnes Crossroads in neighboring Berkeley County, which greeted more than 6,000 newcomers between July of 2016 and July 2017.
