Know Your Flow FAQs

How does it work?

Aurora Water Conservation estimates what your property's efficient water use could be for a given billing cycle if you are using water efficiently. This efficient use is referred to as the Recommended Water Use (RWU). This estimate is based on the following:

1. Number of people in a household. This value is provided by participants. If no value is provided, the rounded median number of Aurora residents per household (three) is used.

2. Weather. This data is acquired from local weather stations.

3. Square footage of landscaped areas on the property. This value is calculated using aerial imagery and our Geographic Information System (GIS).

Why can I only see my actual water use in 1,000 gallon increments?

Since we bill in 1,000 gallon units, any water usage above 1,000 gallons will reflect in your next bill. For example, if you used 5,100 gallons in January, your account reads that as 5,000 gallons. The “remainder” (100 gallons) is reflected in your next month's usage. This means that month-to-month fluctuations are normal (e.g. Jan: 1000 g, Feb: 2000 g, Mar: 1000 g). This may cause your monthly percentage of RWU numbers to look higher or lower than what you used in real life, especially if you traditionally use little water. We recommend looking at the Total percent of RWU field to assess your water use, as this field averages your percent of RWU over time.

Why does my Actual Use show a dash (-)?

The dash indicates that your Actual Use was not available for the month of interest (e.g., you recently moved into your home).

Why does my RWU show a dash (-) or a “0”?

We could not generate a RWU as a result of one of the following conditions:

• Based on your survey responses, you indicated there are no people living in the home during the month of interest. If this is the case, we assumed no water use for that month. If you still have water use occurring without anyone living there and do not know what could be using water, we recommend getting an indoor water assessment to investigate potential leaks. Call at 303-739-7195 to set-up an indoor water assessment.

• Your Actual Use was not available (e.g., you recently moved into your home) and as a result, there was no water use attributed to you. For that reason, we did not generate a RWU or compare actual water use to a RWU.

What do I do if my “Number of People” value is incorrect?

You may contact Aurora Water Conservation at 303.739.7195 to change the number of residents in your household. An accurate number of residents results in a more accurate indoor RWU.

How did you get 41 gallons per person per day for the indoor RWU calculations?

1,250 gallons per person per month is considered efficient indoor use in Aurora, Colorado. By extrapolating this to a year and dividing by 365, we arrived at 41 gallons per person per day. This number is then used in conjunction with the length of the billing cycle to recommend a more accurate usage value.

What do I do if my landscape square footage is incorrect?

You may contact Aurora Water Conservation at 303.739.7195 to request an alteration to your property square footage. Accurate landscape values result in a more accurate outdoor RWU.

Why is there a dash (-) through my square footage estimates?

We have not generated square footage estimates as a result of one of the following conditions:

  • We do not have aerial imagery for your property.

  • Your property was very newly developed.

  • We are in the process of resolving technical issues.

If you see a dash through your square footage estimates, it is possible that we will be in touch to set-up a landscape assessment.

What counts as cool season turf?

Cool season turf is any type of grass that thrives during cooler, wetter periods of the year. They require more water to withstand prolonged hot and dry weather. Typical examples of this grass are Kentucky bluegrass, perennial ryegrass, tall fescue and fine fescue.

What types of plants count as water-wise vegetation?

Anything that is not a cool season turf will be considered a water-wise vegetation area. Examples include: bushes, perennial flowerbeds, native or warm season grasses, water-wise landscaping, ornamental grasses, trees that are not growing in turf areas, annuals, vegetable gardens and ground covers.

What type of vegetation are annuals/vegetable gardens considered?

We consider these water-wise vegetation. Though they may need regular watering, they do not cover the ground as completely as turf and require less water per square foot as a result.

What if I think my actual water use is much higher than expected?
