Without looking, there’s no way to know for sure what your sewer cleaning crew will face underground. That makes choosing which jetter nozzle to use mostly a matter of guesswork. And without any pre-inspection visual information on pipe condition, cleaning crews risk wasting their time and money. A 2015 study even found that up to 35% of sewer lines are jetted unnecessarily as part of scheduled cleaning and maintenance. While CCTV crawlers are great inspection tools, they require a lot of manpower and can be pricey to operate on every cleaning job.

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.

These trends suggest that demand for utility locating will only grow, and that locating itself will become a more and more difficult but essential task as time goes on. To meet the country’s changing needs, wastewater, construction and utilities professionals need to invest in understanding and expanding utility locating services.

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.

Expanding a business requires hard work, good economic sense and often a bit of luck. These four contractors experienced major growth in the wastewater, utilities and locating industries in recent years. Read on to learn how.

The first day that the Tele-Vac Environmental crew took its new ROVVER X SAT II out in the field, they were scheduled to inspect for the Metropolitan Sewer District of Greater Cincinnati (MSD). 

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?
