Billings Will Restrict Lawn Watering Beginning August 2 Neighborhood lawns in Billings may be getting a little browner beginning next month, with the announcement of watering restrictions from Billings Public Works. According to the announcement, Stage 1 water restrictions will go into effect on August 2, prohibiting lawn watering on Monday's for all residential, business, and government properties. The restrictions will remain in place through September 15, 2021. All parks inside the city limits will also be under this watering restriction on Monday's, whether served by the City of Billings or the Heights Water District. Billings Public Works says the watering restriction is being issued "in response to record temperatures, and high water demands." When Stage 1 restrictions go into place, public works crews will be able to address "equipment capacity, overheating issues, and to allow water tanks to fully fill."
