A southern Manitoba town’s water supply is on the verge of going dry.

More than 2,000 residents of Niverville have been asked to stop watering their lawns and filling their pools because the community is at risk of running the reservoir dry.

“I was a little disappointed. This is the season where I like to water my lawn and my flowers and vegetables,” said Dorothy Schapansky, who lives in the town. “Hopefully in a week or two we’ll be able to start watering again.”

Water usage over the weekend nearly tripled and officials didn't catch it until Monday morning, said Deputy Mayor John Funk.

“We haven’t had this spike in other summers for some reason,” said Funk.

At the height of usage the community was using 700,000 litres of water a day over the weekend.

It wouldn't take long to deplete the reservoir at that rate, said Funk.

The reverse osmosis system Niverville uses can produce 500,000 litres a day and usually only produces 200,000 litres per day.

It's been a dry summer and people have been watering their lawns frequently, said Funk.

He also said a number of in-ground swimming pools were installed by homeowners this year, which may be sapping more water than usual from the reservoir.

"It's not just lawn watering," said Funk. "We do know of a number of in-ground pools going in, and they were all filling with that as well."

Since the warning went out, Funk said the reservoir has actually increased by 100,000 litres. He hopes the town can remove the water restriction by the weekend.

“Currently we’re at 8.6 litres per second from the wells into the filtering system,” said Niverville’s manager of public works and operations, Ryan Dyck. “Our goal is to reconfigure so we can get that number up to 9.5 litres per second. That should keep up with the peak demand right now.”

Funk said it was the first time the town has had to restrict water use.
