Cindy Guenther owns Quality Lawn Care Service in Belgrade, and on Friday she was out taking care of her customers' yards.

"We do of course the cutting, we do irrigation- which is your underground sprinklers- we do trimming of bushes" she said.

But there's something she's added to the routine- adjusting sprinkler timers to every other day, because the city's passed emergency water restrictions.

"We started yesterday, and it'll probably take us the rest of the day today and probably Monday, just to make sure that everybody's set up" Guenther said.

Belgrade Public Works Director Steve Klotz said they have six wells feeding two water towers in Belgrade. And recently, they're pumping out more water than they take in.

"When the demand exceeds the amount of time we have in our buffer, then we get into some lower pressures and  lower reserves for fires" Klotz said.

He said it jeopardizes the supply if there's a fire, and water pressure can drop in home fixtures.

"We're wanting them to irrigate every other day" said Klotz. "That should reduce our peak time by about half"

Much of that water goes toward lawn irrigation, so the city decided to restrict when residents can water their lawns.

Here's how the restrictions work- if you live south of Main Street in Belgrade, you can water lawns on even-numbered days.

If you live north of Main Street, then your watering days are the odd numbers.

Local residents told NBC Montana how it affected them. Some told said it's an annoyance, but many said they don't have a problem adjusting.

"I didn't feel upset because I want to have water to put out fires, to drink and take a shower" said Belgrade resident Mary Hoffman, adding "your lawn is nice, but it's down the list on things of importance."

The restrictions are temporary, and Klotz said they'll be lifted when water usage returns to normal.

Guenther told us how you can keep your lawn healthy while following the restrictions.

She said it's best to water your yard between 10 pm and 6 am, avoiding mid-day heat. You can also increase your watering time.

Plus, Guenther suggested leaving your grass a little longer than normal because shorter grass dries out more quickly.
