Last week, I posted a graph of my household water use for the past few years and challenged our readers to identify as many interesting characteristics about my household as they can. Often, the only data a water utility has on their customers are what they have in their billing records. Other household characteristics, such as size of household, income, age, house and lot size and features, water use behavior and preferences, etc., are very difficult to obtain for each customer. However, as demonstrated by my own personal example, mining the billing data alone can reveal much about each household. Here is what my water use history reveals about my household, and the application of this exercise in water resources and utility finance management.
Are you up for a challenge? I have disclosed in this graph my own household’s water use between June 2006 and December 2014, as reported on my water bills. Without any more information about my household’s characteristics (except that it is residential, on a single 5/8″ meter, and using drinking water and wastewater service from one utility), this is the extent of knowledge that my utility has about my household. Yet, my water use data – which are present in the utility’s billing records – reveal much about my household. My challenge to you is to look at this graph and identify as many interesting characteristics about my household as you can. Think about it, too, from the perspective of how the utility should interact with my household. Here are a few questions to consider to get you started:
It’s college football season again, and thoughts among many in the South, and elsewhere, turn to tailgating and touchdowns, hot dogs and sodas, field goals and fun. (Here in Chapel Hill, we like to remember alumnus Andy Griffith’s famous 1953 comical monologue about football, “What It Was, Was Football.”) Meanwhile, those of us at the UNC Environmental Finance Center (EFC) have completed our first-ever Alabama Residential Water and Wastewater Rates Dashboard, which, in fact, ties in with – you guessed it – football! (As well as tying in with the affordability of water and sewer bills by customers in Alabama, of course.) Continue reading
In honor of the World Cup that began last night, we are re-posting a wonderful image that made quite a splash online a few years ago. EPCOR Utilities, Inc., the water utility that serves the City of Edmonton in Canada, tracked the water consumption in the city during the Canada-US Olympic gold medal hockey game in 2010, down to the minute.

Almost two years ago, we wrote a blog post revealing that average residential water use is declining in the State of North Carolina. Similar trends have also been identified in other states and across the country, driven by several factors. It turns out; it’s not just average residential water use that is declining. Despite growing service populations, many utilities have noticed that total demand is falling.
