Stormwater runoff, which consists of rainwater and snowmelt, can cause issues in developed areas where impervious surfaces like roofs and pavement prevent precipitation from soaking into the ground. When water can’t be absorbed into the ground, it can accumulate and cause property damage and flooding, as well as spread disease. 

In the utility locating industry, sondes are radio transmitters that are used to locate non-metal underground utilities. Sonde locating works best when you have an easy access point, as these transmitters are inserted into pipes to identify their location.

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.

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.

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.

The vast majority of sewer systems are built to take advantage of gravity, with sewer lines sloping downward to convey waste to a treatment plant. Although lift stations and force mains can be used when water must be moved uphill, slope is a critical consideration for the design and maintenance of a sewer system.

When sewer systems work, they’re largely invisible to the public. Wastewater flows, unseen, through pipes from homes, businesses and industries to treatment plants, where it is cleaned and returned to the environment. 

But standing pools of water and foul odor—signs a sewer is not functioning properly—are increasingly common.

The design and planning of a sewer system plays a key role in protecting our lakes, rivers and oceans—and the people and wildlife who swim in and drink from them. Treatment plants reduce pollutants, including the human waste, food scraps, chemicals and oils that accumulate in wastewater, so that it can be safely released into the environment.

Generally speaking, pump stations are used to help transport fluids from one point to another. They play an integral role in a handful of infrastructure systems, including sewers. Many sewer systems rely on pumping stations, or lift stations, to push wastewater from point A to point B, especially in cases where gravity can’t move flow from a low-lying area to higher ground. 

The importance of sewer system condition assessments is hard to overstate. Communities depend on sewer systems to carry waste, runoff and pollutants away to a place of final treatment or disposal. Sewer assessment programs can help us better maintain the infrastructure responsible for this—and PACP plays a big role in making sure that’s done consistently.
