Utility locating is more complicated in urban, highly-populated areas where underground utilities are more dense. The population of metropolitan areas in the U.S. increased 9% between 2010 and 2020. However, less than half of all U.S. counties gained population during this period--which means, in general terms, more people are living in denser areas.

In the last few years, per- and polyfluoroalkyl substances (PFAS) have come under harsh scrutiny for the risks they pose to human health and to our surrounding environment. Governing bodies like the United States Environmental Protection Agency (EPA) are studying them to determine what kind of regulations must be instituted to protect public health. This includes limitations on these chemicals in wastewater—PFAS contaminate our collection systems, and current methods are insufficient to eliminate or remove them during treatment.

When Shawn and Sara Wenner acquired Empire Pipe in North Mankato, Minnesota, in 2009, they were taking a gamble. The company exclusively worked with excavating contractors performing post-inspections, and demand had slowed to a trickle during the recession. “It was a baptism by fire,” notes Shawn.

Many of us are familiar with the rotten egg smell associated with sewers. But few people know the real cause behind this distinctive odor. Here’s the rundown on this stinky situation.

Envirosight’s newest poster details the causes of inflow and infiltration, or I&I. Inflow occurs when water from aboveground sources enters sewer systems through illegal or faulty connections or openings. Infiltration happens when stormwater seeps through cracks, joints or manholes into sewer pipes. Together, I&I consists of water that does not have to be treated but ends up in a treatment plant anyway. 

Purchasing a sewer inspection crawler is a significant investment for any municipality. It’s a time-consuming process that involves research, resources and multiple decision-makers. You know that your new crawler’s performance is vital to your organization’s success, but how do you make sure you choose the right system for your needs?

Root intrusion is a common cause of sewer pipe damage. If not properly addressed, root-related issues can wreak havoc on a municipality’s wastewater collection system. Luckily, there are many solutions available to municipalities looking to implement root control measures.
