You can credit it to the spirit of the season — that’s summer swim season, mind you — but one local summer swim team is giving back.

The Bridlewood Bridalwaves, a team in the Prince William Swim League, will celebrate the Fourth of July with its first Firecracker Relays, a fundraiser for the Prince William Health Systems Foundation. The relays will involve teams from across the league and organizer Scott Deibler said he expects about 700 kids to participate. The goal: To raise $3,500 at one meet.

Deibler said Bridlewood wanted to organize an event that incorporated all 24 of the PWSL teams — and he said only those that already had meets scheduled won’t participate — and doing it to benefit a local charity was extra incentive.

“Every team is in the county and that’s an obvious place every team in the county can get behind donating to,” Deibler said.

Foundation spokesman Ken Collins said the group’s primary mission is to provide healthcare for people who can’t afford it, including the homeless in Prince William County.

“We’re really excited that out of the charities out of our community that they did choose us,” Collins said.

The foundation aids the Prince William Community Health Center, as well as about a half dozen more clinics throughout the area. Last year it donated $150,000, in addition to a $10 million campaign for the Health Center.

The meet starts at 7:45 a.m. on Saturday and Deibler said he expects it to run through about 11:45 a.m. Twenty events will take place, with two heats in each event. Admission is free and money from concessions and T-shirt sales will go directly to the foundation, he said, because a local business covered the costs of the meet.
