Commerce City gets its water from Adams County. North of E. 96th Ave, the county constructed a dual water supply system: drinking water and irrigation water. Pretty cool, in my opinion. I’d never seen anything like this before moving here. Anyhow, to balance out demand, Adams County created a “mandatory watering schedule”.

When we can water

Irrigation watering is allowed three days a week, from evening until morning: between 6pm and 10am.

The actual days we can use the irrigation water depends on whether our street address is even or odd.

Address	Irrigation Days
Even:	Sunday, Wednesday & Friday
Odd:	Tuesday, Thursday & Saturday
