• First street-runoff harvesting curb core in Colorado Springs

• Augmentation Plan – allowing for rainwater tanks larger than 100-gallon capacity:

• You can get permission to harvest rainwater in tanks well above 100-gallon capacity if you get “Augmentation Plan” approved by the water owner/provider such as the City of Denver water department.

• They have a limited municipal water supply and they want you to harvest water to make their municipal supplies go further.

• This is from Denver landscape architect/designer T. Barnabas Kane (barnabas@newwestworkshop.com), who has successfully applied such augmentation plans.
