Earlier, 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 the graph below 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. I will reveal answers later this week (stay tuned!).

Springtime in North Carolina normally showcases two things I love: the environment and teamwork. Even if your work doesn’t involve environmental protection, it’s hard not to think about environment this time of year with trees budding out in a green … Read more

It was a beautiful morning as I made the one hour drive from Reno, Nevada to the small rural mountain valley community of Portola, California. Each turn brought increasingly picturesque views of mountains, forests and lakes. As I started my descent into the city, I noticed a slight haze in the valley. Could it be fog? Was it an oncoming storm? Perhaps a forest fire? At another time of year, it might have been any of these natural causes. But at this time of year – early March, temperatures in the 30’s, no wind – it was none of these. What I was seeing hovering in the valley was a layer of smoke and I was going to be spending my day discussing the environmental, economic and health benefits of reducing it.

Our first post this week presented overall findings from a survey conducted on communication between staff and elected officials regarding water utility finances. As many would assume, a solid working relationship between the two parties is important to full-cost recovery. But, when hearing a rate case, what information matters most to elected officials?

The survey asked elected officials what kind of information is the most important in helping them make the best decision about a rate increase for the water utility. It also asked administrators what they believed to be the most important information to share with elected officials. This allowed a comparison to be made between elected officials’ and administrators’ responses.

The water industry is facing unprecedented capital needs, needs which will largely be recovered through increased rates. Sitting between public utilities and the public are governing boards trying to make the right decision for their community and the utility. What information do governing boards need to approve a water rate increase? What are the most effective methods of communicating the need for a rate increase?

North Carolina’s Research Triangle has for years been featured on the list of seminal bests. Raleigh, Durham, Cary, and Chapel Hill are some of the most educated, economically prosperous, family friendly, sustainable, and high-performing cities in the country. The area is even known for happy marriages, rockin’ music scenes, and tasty food. All of these distinctions have helped the Triangle, particularly Raleigh, achieve prominent spots on Forbes 2014 list of America’s fastest-growing cities.

These great features have drawn hundreds of thousands of new residents to the Triangle and its surrounding regions. Researchers at the Renaissance Computing Institute (RENCI) at UNC Charlotte estimate that the population in the Triangle and Rocky Mount areas grew by more than 1 million between 1976 and 2005, a surge of nearly 90 percent. During that time, RENCI found that land development increased nearly 570 percent, from 39,743 developed acres to 264,883 developed acres.

This rapid urbanization has significantly impacted surface water quality in nearby Jordan and Falls Lake and the Upper Neuse River Basin. The 2009 Jordan and Falls Lake clean up rules are estimated to total $750 million and $1.5 billion, respectively. Though the rules have been delayed, larger cities such as Cary, Apex, Morrisville, and Durham could bear the brunt of these costs. The Upper Neuse River Basin rules also place nutrient reduction limits on new development in Durham, Johnston, Orange, Wake, and Wayne counties.
