From The Colorado Springs Gazette (Fredricka Bogardus):
Adoption of permanent water conservation principles prior to a drought crisis makes sense. We live in a semiarid climate and will have periodic droughts. Long-term planning is always less costly and painful than crisis response.
The new ordinance addresses the frequency and time of watering for those using automatic sprinkler systems.
1. You may operate sprinklers up to three times per week, your choice of days. This is adequate frequency for turf and almost all plants that will do well in our climate.
For more information on turf irrigation frequency check out Colorado State University fact sheet 7.199 Watering Established Lawns (https://extension.colostate.edu/topic-areas/yard-garden/watering-established-lawns-7-199/).
2. Between May 1 and Oct. 15, sprinkler operation is prohibited from 10 a.m. to 6 p.m. During the warm hours of the day, most water applied will be lost to evaporation. While it might seem to be a good idea to run the sprinklers mid-day when it is very warm, it will actually be less beneficial to the turf than watering at a cooler time of the day.
3. Drip irrigation, watering cans and hose watering with a shut-off nozzle are allowed at any time.
4. If you are establishing a new landscape or have other special circumstances, you can apply to Colorado Springs Utilities for a permit or allocation plan.
5. Broken or leaking sprinkler systems are required to be repaired within 10 days.
6. Water runoff across nonirrigated ground, street or sidewalks is prohibited.
