The clean-up is well underway in Windsor after the end to the six-day FINA World Swimming Championship.

Crews are busy at the WFCU Centre Monday, draining 1.4-million litres of water from the 25-metre pool, to turn the facility back into a hockey venue.

The President of FINA says Windsor did an “outstanding job” hosting the world class event.

The City has hired the Canadian Sport Tourism Alliance to calculate exactly how much of an economic benefit the world swim championships had on the area.

Estimates suggest it is upwards of $20-million.

Windsor Mayor Drew Dilkens says the $3-million the City paid to host FINA is money well spent.

Dilkens notes thousands of visitors spent at least a week in hotels, eating at restaurants and shopping in stores across Windsor Essex.

While Canadian swimmers enjoyed their best performance at the Worlds since 1999, many businesses are also happy with the outcome of the event.

The Best Western Plus Waterfront Hotel says more than 300 rooms were sold out for 10 days.

Manager Moe Razak tells CTV Windsor "it has done wonders for us, especially in December, a slow period.”

Restaurants across the city also hired extra staff for the influx of visitors.

More than 1,000 swimmers from about 175 countries competed in Windsor. Many of the athletes say they are leaving the City with great memories.

Members of Team Australia built a snowman during Sunday’s snowfall, an experience they have never had before.

Members of the Iceland swim team also say they documented their entire visit through a video that they will share with family and friends back home.
