Johnstown, CO - June 22, 2021 – With extreme temperatures the past two weeks (and for the foreseeable future), water usage in Town and in surrounding areas has increased and is over-stressing the water system during the Town’s peak water demand periods. The water schedule below is specific to automatic sprinkler systems and irrigation systems. If you hand water, use a watering can, or manually move a sprinkler device, the Town requests that you refrain from watering between 9am-6pm and be conscious of water use and over watering. The goal of this watering schedule is not to prevent irrigation, but to be more purposeful with the demand on water so that the water tanks have time to refill for continued use for the entire community.

Automatic sprinkler systems and irrigation systems will be watering every other day between the hours of 9pm-2am and the watering schedule is determined based on house number with even numbered homes using the 9pm-2am period that begins on the even numbered day of the month. Odd numbered homes would be using the 9pm-2am period that begins on the odd numbered day of the month for watering/irrigation.

House Number Dates Time/Hours
EVEN House (ex: 14, 118, 450) 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 Between 9pm (even day) and 2am (the following day)
ODD House (ex. 23, 277, 433) 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31*
*when applicable
Between 9pm (odd day) and 2am (the following day)

Those who are hand watering or using a manually placed sprinkler are, again, asked to water every other day based on the schedule above BUT can water any time prior to 9am or after 6pm.

Town Council, during Monday’s Town Council Meeting, opted not to pass a compulsory ordinance regarding the water schedule at this time. However, Council encourages support and responsible consideration of this water schedule and will consider enforceable or compulsory measures in the future if needed.

As of today, the Town is also doing its part to lessen the demand on the watering system, changing its watering of Town parks and greenery to late evening watering and cutting down watering to every other day. At this time, availability of Johnstown water to construction/development sites has been halted in an effort to prioritize current resident needs.

The Town first implemented a watering schedule last Summer, when temperatures and drought conditions were similar and Town water tanks were experiencing unsustainable peak water demands when inclusive of outside irrigation. Watering schedules give the Town’s water system the opportunity to even out the demand for water thereby improving water pressure and accessibility for all residents during periods of extreme heat.

Earlier this year, the Town raised water and sewer rates to be able to afford the maintenance and operation of current infrastructure as well as better and newer infrastructure to support current residents. While a watering schedule is necessary this summer, the Town has upcoming projects that address water capacity such as the construction of a south water tank starting in September, the water treatment plant expansion that is currently under review to hire an engineering firm, and the upsizing of the raw water pipeline in the coming years.
